F. Information about the Users
Which stakeholder(s) does the record primarily focus on?: Local people and National / local private sector
G. Information about the sustainability of use
Is there evidence that the use is having an impact on the target species?: Wild species sourced from its natural habitat
Has an assessment (or judgement) of sustainability of the use of the target species from an ecological perspective been recorded?: Yes, considered sustainable
Details of assessment carried out: This NDF Case study
Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Efforts by government, such as moratoria on commercial fishing and careful adjustments to total allowable catch should enable this fishery to be sustainable in the future.
Has an assessment (or judgement) of sustainability of the use of the target species from an economic perspective been recorded?: Yes, considered sustainable
Details of assessment carried out: This NDF Case study
Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Provided the conch fishery remains ecologically sustainable. According to the ICA (Instituto Colombiano Agropecuario) registries (Carlos Borda, personal communication), between the years 2000 and 2003, Colombia queen conch exports totalized more than $USD 3.2 million, with pearls accounting for 63%, conch fillets 36% and shells less than 1%.
Has an assessment (or judgement) of sustainability of the use of the target species from a social perspective been recorded?: Yes, considered sustainable
Details of assessment carried out: This NDF Case study
Brief summary on why the use has been assessed/judged to be sustainable or unsustainable: Fishing practices may be exploitative: The combination of diving with old and poor-quality gear, fishing deep (140 feet) and frequently (up to 15 times a day) threatens serious decompression sickness and results in significant socio-economic impacts to already poor communities, such as the Miskitos Indians.

Recommendations provided in the record to maintain or enhance the sustainability of the use of the target species
• Improve regional controls regarding illegal fishing and get consensus among managers in the south-western region to account for illegal fishing when defining TAC for CITES. • It may be appropriate to include a minimum spawning population density as a fundamental sustainability criterion in regional conch fishery management regimes. • Conduct regional connectivity studies to determine the level of larval supply and connectedness to maintain key “stepping stone” populations. • Strengthen precautionary measures if a population is composed mostly by very old adults (perhaps low recruitment) or juveniles (reducing reproductive output). • Promote bi-national agreements to reach consistent regional management strategies and policies, particularly in the areas with existent international treaties. • CITES may continue acting as a dominant force in enforcement. In fact, specific enforcement workshops and better communication among managers in the South-western Caribbean region were recently identified as a priority to strengthen the functionality of a queen conch networking. • To overcome budget limitations, a more coordinated research agenda and collaborative work should be explored to address critical knowledge gaps.
