Résumé
|
Leatherback turtles, Dermochelys coriacea, have not previously been reported nesting in
Vanuatu. A review of archival data, unpublished reports, interviews with key informants from coastal communities, and a nesting beach survey indicates that leatherback nesting occurs on a number of islands, including Pentecost, Ambrym, Malakula, Epi, and Efate. Leatherbacks are opportunistically consumed in some areas, particularly Malakula, where 5 have been reported killed in the past 7 years.

Résumé
|
Community fisheries management (CFM) has been introduced in fisheries management in Vanuatu almost over a decade ago. Today, most of Vanuatu’s coastal zone fisheries are managed under CFM system. However, it appears that the current CFM is inefficient, weak and unsustainable. In this study, the actual form of CFM in Vanuatu is described and compared to the Arnason design principles for an efficient CFM. According to Arnason approach, CFM is a form of property rights regime. It was found that Arnason design principles existed to some certain degree in CFM in Vanuatu. The CFR appeared to exist as moderately strong. However, it was not efficiently utilized because of the set-up and organization of the communities. Nevertheless, there is overall practical applicability in the context of CFM in Vanuatu.

Résumé
|
Vanuatu's involvement in trochus research commenced in the early 1990s and its in involvement in the Australian Centre for International Agriculture Research ACIAR trochus funded project spanned over 10 years. This encompassed 3 phases of the ACIAR trochus funded research project, with phase 1 of the project involving nutritional aspect of trochus, phase 2 concentrated on hatchery seed production and reef reseeding and the final phase concentrated on broodstock enhancement using a community-based management approach. Constant involvement of Vanuatu in trochus research demonstrated the importance of this resource to the economic and social well being of the rural communities of the country. Emphasis has been placed not only in assisting communities to developing best community based management guidelines to promote its long-term benefits but also to use experiences gained in trochus to managing other commercially viable inshore resources such as green snails and giant clams in the country.
Establishment of taboo areas or marine protected areas (MPAs) was achieved in all project sites through establishment of local coordinators and active participation of the communities concerned which in turn greatly assisted in the management decision makings of the areas concerned. Involvement of the local coordinators in field aspects of the enhancement work as well as dissemination of information on project updates during the project phase was useful in giving the communities and their coordinators an insight on the importance in managing trochus as a valuable resource for their livelihood. Results revealed that MPAs and/ or closed areas were highly effective in protecting seeded stock and allowing recruitment to proceed. Enhancement was recorded to be more effective in the seeded area compared to the control (unseeded) areas. Towards the end of the project, adult density in the seeded sites has reached harvestable numbers.
Overall, the involvement of Vanuatu with partner countries (Australia and Samoa) in the recent study was useful in terms of information sharing and technology transfer. Vanuatu has assisted Samoa by shipping some 1000 adult trochus in 2003 to establish trochus population in Samoa. Likewise Vanuatu benefited from experimental designs, data analysis and sampling techniques from its Australian counterparts. This report outlines the achievements of the three year project since its implementation.

Résumé
|
The commercial trade of ornamental fish for aquarium industry has become of recent concern in Vanuatu. A dramatic increase in export quantities over the past 12 months without subsequent increase in fishing locations or managemnt regulations, has generated many political, socio-economic and environmental issues. As is the trend throughout Asia-Pacific region very little knowledge and understanding currently exists on the dynamics of coral reefs and the impact that extractive fisheries have on sustainability. a quantitative survey of reef systems, involving estimation of ornamental fish abundance and species diversity, was carried out at 15 locations around the south and west coast of Efate Island. Results indicate that in the regions where the greatest amount of fishing for ornamentals occur, communities are of a marked lower quality. Disruption of community structure has a variety of detrimental consequences and it is recommended that the extent of this demarcation be quantified. Achieving a more conservative management of this industry is necessary and the use of area and species prohibition, along with the necessary procedures for further assessment and monitoring, are discussed in this paper.

Résumé
|
The Vanuatu Coral Reef Monitoring Network Project commenced in early 2002 as a new project coordinated by Kalo Pakoa under the research section of the Vanuatu Fisheries Department. The aim of the project were to: set up monitoring sites and a coral reef monitoring database, conduct surveys, establish linkages between government, NGOs and the private sector, conduct community-based education and awareness, provide training on monitoring methods and provide country status of reef reports to the South West GCRMN node coordinator.
It was decided that only two sites were to be established and monitored for three years. The sites were selected in close proximity to Port Vila for easy accessibility and representative of both high and low human-impacted sites. It was recommended that the Reef Check method be used for surveys.

Résumé
|
The islands of Vanuatu are surrounded by narrow fringing reefs, which are least well developed and are constantly coming under the influence of natural disturbances such as cyclone, tectonic activities and global warming. Although human impact is reported to be generally low, reefs are generally considered to be in a poor condition and damage by cyclones, coral bleaching, and crown of thorns starfish is widespread. A survey in the late 1980’s reported that cyclone damage was evident in 50% of the sites surveyed throughout the country and coral mortality was widespread. Crown of thorns were seen active in 10% of the sites and reefs near urban center are under pressure from anthropogenic disturbances (Done and Navin, 1990).
The major threats affecting coral reefs in Vanuatu includes: over use (overfishing), sedimentation and run offs, urbanization and sewage pollution, natural catastrophic events such as cyclone damage, tectonic uplifts and global warming (bleaching) (Done & Navin, 1990, Naviti & Aston, 2000, Sulu et al, 2002,). According to the reef check monitoring survey information, the most recent threat comes from the inevitable temperature rise that show the destruction of large coral reef areas in 1998 and 2002 throughout the country as a result of bleaching. The Vanuatu Coral Reef Monitoring Network (VCRMN) was designed to assess and detect changes in coral reefs and increases our understanding of the controlling factors (both natural and anthropogenic) influencing the reef stability. In addition it was designed to strengthen the local capacity for data collection, analysis and dissemination of data on coral reefs to communities, schools including different levels of management authority. This report presents a brief summary of the findings of the Coral Reef Monitoring Project survey conducted from the period of March 2002 to March 2004.

Résumé
|
Recently there has been an increase in awareness for the need of conservation of marine mammals in the South Pacific Islands with the project of creating a Sanctuary for whales in the South Pacific. This is the reason why, following the increasing interest of local people for marine mammals conservation in the South Pacific region, Natural Heritage Trust (Australia) funded the South Pacific Whale Research Consortium to develop a research project on assessment of marine mammals in Fiji, Samoa, and Vanuatu. Operation Cetaces was to undertake the research in Vanuatu.
A first sea-based survey was undertaken in August 2003 in the southern Islands of Tanna and Aneityum. A total of 16 humpback whales were observed, including solitary whales, singers, pods of two adults, mother and calf. Good quality whale songs were recorded when possible. These observation indicate that humpback whales use the southern islands of Vanuatu as a reproductive ground.
The confirmed distribution of humpback whales around Futuna and Efate suggest that humpback could have a wider distribution and could possibly exist around other islands.
The first catalogue of photo-identified humpback whales for Vanuatu was established, it contains six animals individually identified by the underside of their fluke or f1ukeprint. This catalogue has been compared to the existing catalogues of the South Pacific in collaboration with members of the South Pacific Whale Research Consortium. One animal has been matched to New Caledonia and two to Tonga, adding to the knowledge concerning movements of humpback whales in the South Pacific.
A total of seven species were identified in the waters of Vanuatu, they are: sperm whale, humpback whale, spinner dolphin, pan-tropical spotted dolphin, melon-headed, tropical pilot whale and dugong. Other species that are potentially present include: minke whale, brydes whale, common dolphin and bottlenose dolphin.
Stakeholders were met with in order to collect information. Capacity building was limited, no university section in biology, very few NGO, and small environmental and fisheries section inhibited such develop. The Cultural Vanuatu Center and some of the private tour operators were the only groups to indicate a desire for a continuing relationship.

Résumé
|
Fishing has always been considered secondary to agriculture in Vanuatu. However, a village subsistence fishing survey conducted in 1983 indicated that over 50 percent of the countrys rural population engages in fishing. Apart from the collection of trochus and green snail for the production of button blanks etc. in local factories, most of the fishing within the reefs and lagoons has been on the subsistence/artisanal level. Reef and lagoon fishes as well as non-finfish animals such as lobsters are becoming increasingly important in the artisanal level. The current decreasing trend in the number of boats engaged in the bottom-fish fishery is a possible indication of the likely increased pressure on the inshore resources. Export of bêche-de-mer and aquarium fish has been relatively small and erratic in the past. However, recently they have become major marine products exported, particularly the aquarium fish trade. At present, trochus is one of the major lower scale, higher prices are offered for green snails.
Due to the decline in prices of agricultural products, especially copra, coconut crabs have become a target species and form an important component of the income of the inhabitants of the more remote islands.
Two animal species have been introduced into Vanuatu in efforts to develop aquaculture initiatives in the Republic. These introductions of new species involved the marine Pacific oyster, Crassostrea gigas and the giant Malaysian fresh-water prawn, Macrobrachium rosenbergii. The oyster culture trials were conducted in three different areas but all failed due to poor growth, high mortality and predation. Good growth results were obtained from the trials conducted on Santo but predation and irregular spat supply were problematic. No information could be located on the failure of the Macrobrachium project but indications are that it may have been caused by high mortality and slow growth rates attained and possibly land disputes. The Department of Fisheries has recently (2004) commenced research work on farming of imported Tilapia fish and the local fresh water prawn, Macrobrachium lar. Future intention would be to diversify to include Macrobrachium rosenbergii.
Vanuatu was one of the countries included in the study conducted by the FAO/SPADP on the potential of green mussel aquaculture in 1989. The study indicated potential sites within the Republic, especially Erakor Lagoon, but water quality (pollution) could be a problem. The Fisheries Department currently operates a small-scale hatchery for three native mollusc species, Trochus niloticus; the green snails, Turbo marmoratus and Tridacna crocea and maxima species The hatchery work on these species is for re-seeding purposes.
The Fisheries Act 1983 is currently under review. This process would hopefully lead to changes that seem necessary in the Fisheries Regulations currently in force. There is clearly a need for coordination in this area with other agencies to define responsibilities clearly to avoid conflict and overlap in work programmes, which should complement each other.
During the recent past, the Department of Fisheries has commenced studies on fresh water resources. Preliminary observations indcated that there is a potential in development of aquaculture using the fresh water indigenous fish species.

Résumé
|
Coconut crabs are a vital resource for many small communities in Vanuatu. The collection and sale of these crabs is sometimes the only form of cash-crop available in many remote regions making the conservation of this resource of paramount importance. This need was highlighted in the previous ACIAR and AIDAB funded studies conducted between 1985 and 1992. These studies revealed that the crabs grew slowly, recruitment of juveniles may not be large and that the numbers of adult crabs in an area could be reduced very quickly. At the conclusion of these initial projects, a series of recommendations were provided for the Vanuatu Government to assist with the development of a management strategy to protect the remaining stocks of crabs. This resulted in a set of management restrictions being imposed in July 1991which included the use of closed seasons and a restriction on the numbers of crabs that could be taken each year from the key areas. These controls were in addition to the minimum legal size and protection of berried crabs that had been in force since 1983, but had been ineffective in halting the decline in crab stocks. In many areas, stocks were suffering from growth overfishing and potentially recruitment overfishing.
The purpose of the present ACIAR funded study was to re-examine the stocks of coconut crabs in Vanuatu to determine if the management arrangements introduced 10 years ago have been sufficient to conserve the remaining stocks. Furthermore, if necessary, suggest ways that controls could be revised to improve the management of this important resource. Finally,
complete the initial assessment of crab stocks for areas where significant collections of crabs have only recently begun.
Consequently, the terms of reference for the study were to:
1. Re-assess the stocks of coconut crabs in the Torba and Sanma Provinces where management has been in operation for 10 years
2. Ass ess the relative impact of current management arrangements on markets for the crabs and the benefits/costs to each of the above regions
3. Using the results of TOR 1 & 2 in conjunction with stakeholder input and market surveys, review existing management arrangements for the Torba and Sanma Provinces
4. Provide estimates of the status of stocks within the Tafea Province which has been identified as having potential for ongoing commercial harvesting but formal management arrangements have not been developed
5. Propose initial management arrangements for the Tafea Province
6. Following broad stakeholder consultation on the proposed arrangements, develop firm recommendations for future management action in the Tafea Province.

Résumé
|
period between 1998- 2000 on the status, abundance, distribution and diversity of beche-de-mer, giant clam, rock lobster and Coconut crab (Birgus latro) resources in the Vanuatu archipelago. These marine resources are socially and economically vital not only to the rural coastal people but also nationally. In remote rural areas of the country some of these resources may be the only form of cash crop available providing much needed cash for daily living and most importantly school fees and health
fees.
As the country continues to expand in its population and attempts are being made in the diversification of its economic base, and due to the low prices in the agricultural products particularly copra and cocoa, attention is being diverted to the Marine resources. This may have put a lot of fishing pressure on the marine resources. Because stock assessment is one of the key information indicating level of exploitation and resource stock it is therefore of great significant that such surveys be carried out. This could enable fisheries managers and particularly the policy makers to monitor trends of resources stock thus in a better position of formulating effective management regulations concerning the marine resources thus ensuring resources sustainability.
Funding of this assessment survey was made possible through the US treaty Project Development Funds for Vanuatu. The need to carry out this survey was identified by the Director of Fisheries Department Mr. Moses Amos, then, Fisheries Principle Biologist and Head of RAMACIS mainly due to the difficulty faced with in the management of coastal resources such as beche-de-mer, giant clam, rock lobster and coconut crab (Birgus latro).
The primary objective of the stock assessment survey is to develop a precautionary principle to sustain the beche-de-mer, giant clam, rock lobster and coconut crab resources and to provide a viable alternative to the rapidly declining of the fishery in Vanuatu. The objectives of the survey were as follows:
• Find alternative procedures that will help facilitate development and sustainable management
of the beche-de-mer, giant clam, rock lobster and coconut crab (Birgus latro) resources in the
Vanuatu waters.
• Develop a monitoring procedure of beche-de-mer, giant clam, rock lobster and coconut crab
(Birgus latro) stocks which will enable better assessment of the resources.
To effectively meet the objectives of the survey, three main areas of research were proposed:
• Stock assessment of beche-de-mer, giant clam, rock lobster and coconut crab (Birgus latro)
resources within the archipelago.
• Awareness program
• Hatchery production of giant clam seeds.
Although this report may be outdated, the results will provide useful information and aid the Fisheries Department to make realistic management policies and regulations concerning these respective coastal marine resources.

Résumé
|
Giant Clam meat is an esteemed food item for the ni-Vanuatu people and because of its large meat volume, it constitutes an important component of sea-food consumption in the subsistence fishery. Vanuatu has very limited giant clam resource which has been exploited by the subsistence fishery for many years. Sale of clam meat is not common in the public markets in Port Vila and Santo, an indication that the resource is not large enough to support even a small giant clam meat market.
In 1997, Vanuatu began trading wild giant clam to the marine aquarium market which mainly comprised of species, Tridacna crocea, T. maxima and T. squamosa due to their beautiful colouration. The dull colours of Hippopus hippopus made it unsuitable for the aquarium market and was not targeted by the trade.
This report provides an overview on the status of the giant clam resource of Vanuatu and the existing mechanisms in place to ensure sustaianble management of this resource.

Résumé
|
There is no systematic monitoring programme for coral reefs in Vanuatu. The Fisheries Department is focussed on rural fisheries development and stock assessment of inshore fisheries resources. Monitoring began in 2002 with funding from CIDA through the SW Pacific Node of the GCRMN. A team comprising staff from fisheries and environment departments established the sites on Efate, conducted surveys and stakeholder consultations (tour and dive operators, communities, NGOs)

Résumé
|
The purpose of this survey is to assist the Fisheries Department in gathering data for the stock assessment program so management strategies can be formulated for the long term. This stock assessment survey was year two of a three-year program. The survey encompassed the Torba Province, which is the northern most province of the Vanuatu group and is made up of the Banks and Torres group of islands. The species surveyed were beche-de-mer, rock lobsters, giant clams, and coconut crabs. This area has not been surveyed before so this will provide a base line for future surveys and play an integral part in formulating management plans for the fishery.
In order to gain some insight and understanding of the state of the Vanuatu fishery a brief In order to gain some insight and understanding of the state of the Vanuatu fishery a brief history has been documented in the report. This illustrates how and why the fishery is seemingly undeveloped and under utilised. Many schemes have been started and failed leading up to Vanuatus independence and Republic formation. Every aspect of the growth and development of the fishing industry in Vanuatu is dictated by the financial position of the country, therefore any progress will be slow and calculated.
Giant clam and beche-de-mer made up the bulk of the first part of the surveys using transect and timed drift methods. The most prolific species ofbeche-de-mer found was the lolly fish although a scattering of other species were recorded. Although the lolly fish are of low commercial value their ability to reproduce in large numbers and several times per year shows them as having great potential as a commercially cultured species. There are eighteen species ofbeche-de-mer known to be present in the Vanuatu waters.
The giant clam Tridacna maxima was the most abundant clam of all found with encouraging numbers recorded throughout the islands. Hiu Island had the highest density of clams. The two larger species, Tridacna squamosa and Hippopus hippopus, which are commonly harvested, are very limited and the numbers found were not adequate to sustain harvesting.
The lobster surveys differed slightly in as much as they were carried out during the hours of darkness for the simple reason that they are nocturnal and come out to feed at night. Of the three species, the double spine is by far the most prolific lobster (58%) on all the islands except Reef Island. On this island the painted lobster recorded slightly more than the double spine, which simply may be because the latter is the most preferred species for consumption. The slipper lobster accounted for a small proportion of the total lobster count (11%) except for the site on Pakea Island. As is with the painted lobster the slipper is not popular for
consumption and is generally left alone. Because the slipper lobster is much smaller than the other two, competing for habitat and food would be difficult, which could also explain the low overall numbers found, which tends to suggest that sustainable harvesting would be marginal.
Coconut crabs are probably the biggest revenue earner of the Torba province and the least known about, especially when it comes to the state of the population. It is widely known that the majority of coconut crabs in Vanuatu come from the Torres group especially the island of Hiu. The pressure on the stocks is ultimately controlled by the demand for the product. More often than not the demand for crabs is higher than the supply. The effects of over harvesting was present at several sites and the increasing exploitation is of growing concern to some of the locals.

Résumé
|
The definitions in this document are those used in the Fisheries Act. “Fish” means any aquatic animal, and includes any mollusc, crustacean, coral, sponge, holothurian, or reptile, and all their young and eggs, and includes coconut crabs. “Fishery” means one or more stocks of fish or fishing operations based on such stocks which can be treated as a unit for purposes of conservation and management and which are identified on the basis of geographical, scientific, technical, recreational and economic characteristics. For the purposes of this document, “fisheries development” also includes the aquaculture and mariculture.
Vanuatu’s fishery resources support a wide range of fishing activities, including:
• subsistence harvesting of inshore fish and invertebrates;
• commercial collection of trochus and other shells;
• commercial harvesting of deep-bottom fish;
• game fishing;
• commercial trolling for tuna and coastal pelagic fish;
• foreign-based industrial tuna fishing;
• domestic longline fisheries for tuna;
• exploitation of miscellaneous other resources such as beche-de-mer, lobsters, and
aquarium life.
There is the potential for increased exploitation of certain resources, particularly those for tuna and coastal pelagic species, and for the domestication of the foreign-based components of Vanuatu’s fisheries.
The Government has a key role to play in the development and management of these resources which, if exploited within the limits of sustainability, will allow the long-term generation of food, income and employment opportunities for ni-Vanuatu people, and of foreign exchange for the national economy. For this to occur, however, the principles of sustainable development must be applied to ensure that the growth of the fishing industry is balanced by the need to conserve fishery resources for future generations.
This policy statement sets out a blueprint for the future management and development of Vanuatu’s fisheries. It defines the role of Government in the administration of the fisheries sector, spells out the Government’s major policies in this area and, where appropriate, provides some indication of the thinking behind these policies. It also describes Government’s expectations in regard to the roles of the private sector, non-Government organisations, traditional resource custodians, and others.
The policies laid out in this document take into account the constraints that have been identified as hindering the sector. In the medium term, they are aimed at optimising the economic benefits to Vanuatu of the exploitation of its fisheries resources, and at
strengthening the administration of the sector. Over the longer term, the Government’s goal is to ensure that fisheries management is carried out in accordance with the principles of sustainable development.
The purpose of this paper is to inform the private sector, other Government Departments, non-Government organisations, and the public at large about Government’s broad policies in regard to fisheries. As such it is intended for wide circulation. The document provides written evidence of the Government’s commitment to the wise development and management of fisheries in Vanuatu.

Résumé
|
Overall, fisheries play a small part in Vanuatus formal economy. Marine product exports in 1995 were 113 million Vatu, about 3.6% of total exports, of which 89% were trochus and green snail products. Additional revenue of about 36 million Vatu is generated through licensing of foreign fishing vessels, even though those vessels rarely fish in Vanuatu waters.
Domestically, however, fisheries are important in providing nutrition and income-earning opportunities, particularly in rural areas. Overall production was estimated to be about 2,500 tonnes in 1990, of which 80% was taken in the subsistence fishery.
There is considerable overlap between subsistence and commercial fisheries. Much of the production from subsistence fisheries is sold, and many households rely on income from marine product sales of some form. The main commercial fisheries are rurally-based, carried out at a village or community level, and constitute only a part time occupation. In this sense they have more in common with subsistence harvesting than with “true” commercial fishing.
The two most important commercial inshore fisheries in Vanuatu are in need of improved management:
• the deep-bottom fishery, which is carried out by about 122 small (5-7 m) boats based in rural
areas, currently produces 50-70 tonnes annually, about half the fish sold domestically in the
country. This fishery should be managed through the introduction of a small-vessel
licensing scheme to allow limitation of fishing effort, and through the declaration of three
Fishery Conservation Areas around the islands of Efate, Espiritu Santo and Malekula;
• the shell fishery (for trochus and green snail), which provides income for rural residents
throughout Vanuatu. This fishery should be managed through an immediate cap on the
number of processing factory licences issued, continuation and, over the longer term,
possible reduction of a per-factory shell quota, and continued encouragement of customary
marine management measures.
Other domestic fisheries target reef fish, inshore and coastal pelagics, coconut crabs, lobsters, and miscellaneous other species such as octopus and land crabs. Of these the coastal pelagic fishery shows the greatest prospect for further development in Vanuatu. Given the rapidly expanding (and largely unemployed) population of Port Vila, the large unsatisfied demand for fish there, that the poor economics of fishing in rural areas, development of this fishery should be first and foremost centered on Port Vila. Conservation action (as opposed to fishery management) is needed in regard to coconut crabs. Other fisheries are not in need of management attention at this point.
Other export fisheries are for beche-de-mer and aquarium life. Improved management of the bechede-mer fishery is needed, through customary management arrangements and a reduction of the overall export quota. The aquarium life fishery is not in need of management attention.
The authority that the 1994 Decentralization Act gives to Provincial Governments to manage and licence fishing activities within six miles of their shores should be rescinded. Provincial Governments should be consulted about fishery management and development issues relating to their geographical areas, but should not be responsible for actual decision-making, which should be in the hands of the national Government, via the Fisheries Department.
The Vanuatu Fisheries Department needs to:
• improve the quality, timeliness and accessibility of fishery statistics, especially in regard to
the shell and deep-bottom fisheries.
• formulate a series of management plans in regard to the countrys key fisheries;
• institute a system of licensing and registering all motorised commercial fishing boats;
• put in place a coastal pelagic fishery development programme based in port Vila.
• carry out a number of studies on aspects of Vanuatus fisheries, as detailed in the
recommendations section of the report.
A Fisheries Development/ Management Specialist should be recruited for a period of three years to oversee implementation of the recommendations contained in this report. Section 6 contains 25 specific recommendations made in support of these findings.

Résumé
|
Trochus shell is one of the main source of income for the people of Vanuatu and it plays an important role in the economy of the country. The shell is qualifying as luxury product, as a result of his high quality pearly shell and the high demand from the industrialise country. Due to his rich-protein flesh, collection of Trochus shell has been a traditional activity on the Islands for a long time. However, the exportation of his shell become apparent in Vanuatu only at the end of the 19th century. At the beginning of the 20th. century, French settlers were reported to have harvested Trochus for the shells in Vanuatu.

Résumé
|
The ACIAR (Australian Centre for International Agricultural Research) funded project on coconut crabs (Birgus latro) in Vanuatu was devised to investigate the biology and ecology of this, the largest land crab. Their land-dwelling habits and the fact that they can grow as large as 5 kg have made them highly prized as a traditional food item throughout most islands of the tropical Indo-Pacific. Their unique flavour has also made them popular with tourists at local restaurants. Consequently, during the last 20 years, increasing levels of exploitation and changing land-use in areas where coconut crabs used to be common have contributed to a decline in local stocks. In some areas, this has resulted in their virtual extinction (Amesbury, 1980).
The Republic of Vanuatu is one of the few countries in which natural populations of the coconut crab are still large enough to support harvesting. Since 1983, improvement in transport among the islands and increased marketing facilities have seen a significant increase in the numbers of crabs collected for sale, resulting in increased pressure being applied to a number of crab stocks. Fisheries authorities recognised the need to assess the status of these stocks and to institute a programme of management to regulate this harvesting. The industry (although relatively small) of conslderable soclo-econom1c importance to communities in the more remote areas.
In response to a request to ACIAR from the Vanuatu Government in 1983, the Queensland Department of Fisheries Research and the University of Queensland were commisssioned to investigate the coconut crab to enable a plan of management to be formulated. Despite a considerable history of research into this unique species (more than 200 years), little was known about the basic biological and population characteristics (Amesbury, 1980; Held, 1963; Helfman, 1973). Yet, it is these paramaters which are vital for managing any exploited stock. The major aims of the study therefore, were to:
a) estimate the crab's natural growth rate;
b) examine the effects of harvesting pressure on population;
density and structure; and
c) to study the process of recruitment;
