    Conversion factors for processed queen conch to nominal weight/ Factores de conversión para el caracol reina procesado a peso nominal 2009

    Queen conch (Strombus gigas) is one of the important fishery resources in the Caribbean in terms of its annual landings and its social and economic importance. Queen conch is an edible marine gastropod of the Caribbean region that has been listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which allows international trade of the species only after certain conditions are met. An FAO FishCode STF*/OSPESCA** workshop held in Panama identified the need to be able to convert the different processing grades to nominal weight. Three countries (Dominican Republic, Honduras and Nicaragua) volunteered to participate in a field experiment to establish the conversion factors. This investigation resulted in the establishment of conversion rates for different processing grades per country. There were slight but significant differences between conversion factors for processing grades between countries, most likely related to different processing techniques used. Within this limitation, the following preliminary regional conversion factors are recommended: 100 percent fillet to nominal weight 16.4; 85 percent fillet to nominal weight 13.7; 50 percent fillet to nominal weight 9.46; dirty meat to nominal weight 5.7.

    Supporting the Implementation of the Regional Queen Conch Fisheries Management and Conservation Plan in the Wecafc Area - GCP/SLC/017/EC 2021

    Each year, an estimated 30 000 35 000 tonnes of queen conch ( strobus gigas ) are harvested across 36 countries and territories, with the largest producer being Nicaragua, followed by Jamaica, Bahamas and Belize. In the Caribbean region, queen conch is the principal marine species under regulation by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). This is attributable not only to its high production but also its value and socio economic significance. To better promote cooperation and coordination in the sustainable management and utilization of queen conch, several regional bodies, including the Western Central Atlantic Fishery Commission (WECAFC), Caribbean Regional Fisheries Mechanism (CRFM), Organization of Fishing and Aquaculture in Central America (OSPESCA) and Caribbean Fishery Management Council (CFMC), formed the Working Group on Queen Conch. In 2014 2015, the working group prepared the Regional Queen Conch Fisheries Management and Conservation Plan, which was later endorsed at the 16th Session of the WECAFC. However, the effective implementation of this plan necessitates adequate human, financial and technical capacities in Member States. This project was therefore designed to assist WECAFC members and working group partners in developing their capacity to better implement the queen conch management plan at the national level.
