Queen conch (Strombus gigas) supports a fishery of economic and cultural importance to the Turks and Caicos Islands (TCI) but is thought to be in decline. It has become apparent that the fishery is facing increased pressures from sustained fishing practices, driven by local demand and international markets.
Led by TCI governmental departments and the Joint Nature Conservation Committee (JNCC), in partnership with Marine Conservation Society (MCS), this EU-funded project 'Sustaining queen conch fisheries and livelihoods in the Turks and Caicos Islands' aims to support programmes of work in relation to sustainably managing TCI’s queen conch fisheries, and address CITES requirements for sustainable international trade in this CITES Appendix II listed species.
This 13 month project is urgently needed to better understand the status of the queen conch population in TCI and inform future management decisions by: completing new conch abundance surveys; assessing domestic and tourist consumption; capacity building within TCI government departments; and producing a CITES non-detriment finding (NDF) to determine sustainable trade levels.
Ultimately, the aim is to secure livelihoods and maintain a steady source of income for TCI by safeguarding this valuable component of the marine environment.

Background
The conch fishery is the second most important commercial fishery in TCI, supporting a large export trade ( more than $3.5 million USD per year) as well as a domestic market. However, it is thought that the queen conch fishery, which previously provided a reliable and plentiful food resource, could be in decline due to increased pressures driven by local demand and international markets.
Sustainable exploitation of queen conch fisheries presents a broad range of challenges, including the complex biology of the species; vulnerability to stochastic events; uncertainty of catch and effort data; illegal trade; weak surveillance and enforcement mechanisms and unsustainable fishing practices.
The sustainability of the fishery is threatened by the absence of a comprehensive stock assessment for the species. The extent of offtake through domestic and tourist consumption and under-reporting makes it impossible for managers to optimize fisheries production in a sustainable manner, which has caused economic losses to the sector. Addressing these data gaps is essential to provide new information which can be utilised to mitigate the risk of over-harvesting queen conch.
Furthermore, as TCI has CITES extended to it, it is also necessary to fill these knowledge gaps on population abundance and consumption levels to underpin a non-detriment finding (NDF – an assessment of sustainability) for this CITES Appendix II listed species, ensuring that future international trade is at sustainable levels and meets the requirements of the Convention. CITES is a complex agreement and capacity building is required to enable the TCI government to meet their obligations under CITES.
This project will provide TCI with the ability to assure a future not only for queen conch and the livelihoods which depend upon it, but also contribute to wider regional management efforts underway in the Caribbean for the species.
Overall aim
To promote sustainable utilization of queen conch, while preserving the environment and enhancing the social and economic livelihood of local people.
Project timeline
- May – December 2022: Underwater visual surveys to determine queen conch population status on TCI.
- July - December 2022: Domestic consumption surveys including interviews with key stakeholders on the nature and extent of conch harvest for local consumption.
- February – March 2023: Delivery of training for TCI government and statutory agency staff on the implementation of CITES.
- April – May 2023: Recommendations to support the recovery of the queen conch fishery: ensuring future sustainability.
- April – May 2023: Completion of CITES non-detriment finding (NDF, an assessment of sustainability) for export of queen conch using the gathered information.
Work packages/objectives
Objective 1: Study to compare underwater visual survey (UVS) methodologies
Working with TCI government, two methods of UVS for queen conch will be compared in a short study: the video camera tow method (a peer-reviewed methodology used previously in Saint Eustatius and Anguilla, for which training will be provided to TCI government staff by a technical expert) and the underwater drone method.
Costs, reliability, habitat impacts, and ease of use will all be assessed, and the results of this method comparison study will inform subsequent survey work.
Objective 2: Estimate queen conch abundance on Caicos Bank ready for integration with other scientific data required to determine the queen conch population status in TCI
Extensive queen conch abundance surveys will be conducted to determine the population size and characteristics of queen conch on Caicos Bank, using dive surveys and video camera tow (and/or underwater drone, depending on the outcome of objective 1).
Objective 3: Determine estimated levels of unreported local harvest
Design and implementation of a sociological survey to determine harvest levels of queen conch for domestic and tourist consumption across TCI, which are currently unreported and unrecorded.
Objective 4: Develop a CITES non-detriment finding (NDF) for queen conch fishery
A complete conch stock assessment, conducted by DECR and based on the data acquired, will inform management recommendations and the development of a non-detriment finding for the export of queen conch. CITES training will be provided for TCI government and statutory agency staff, building capacity for the development of future NDFs for other CITES-listed species and assisting in the pursuit of national product traceability schemes in line with catch certification standard requirements.
Objective 5: Complete a review of CITES implementation in TCI
A critical and expert review of CITES implementation in TCI will identify practical measures to address any capacity building needs. This will include a detailed analysis of current and anticipated trade, including a risk assessment to identify enforcement priorities. Following this needs assessment, in-country training, tailored for relevant officials and stakeholders, will be conducted.
