Book (series)Commercially important sea cucumbers of the world 2023
Also available in:
No results found.Sea cucumbers are harvested and traded in more than 90 countries worldwide. They are exploited in industrial and small-scale fisheries, nearly from pole to pole, especially in the tropics. In some fisheries, more than 20 species are exploited by fishers. Fishers in general know how to distinguish the species they harvest, often identifying them with local names. For fishery officers and even biologists, recognizing sea cucumber species remains daunting however as they are confronted only with the final product: bêche-de-mer (or trepang) which is the processed (cooked and dried) product. This field guide offers a tool for fishery managers, scientists, trade officers and industry workers to recognize live and processed (cooked and dried) animals. This animal resource is mainly exported to Asian markets where it is sold mainly, but not exclusively, as a luxury food item. This book provides identification information on 84 species of sea cucumbers that are commonly or opportunistically (as bycatch) exploited around the world. The list is certainly not all-encompassing, as some other sea cucumber species are also exploited. More scientific data and accounts are needed for species from some regions such as the Eastern Atlantic Ocean. The accounts are based on more than 270 reports and research articles and on comments and reviews by taxonomists and field workers. Two-page identification sheets provide selected information to enable similar species to be distinguished from each other, both in the live and processed (dried) forms. Where available, the following information for each species has been included: scientific and known common names used in different countries and regions; scientific illustrations of the body and ossicles; descriptions of ossicles present in different body parts; a colour photograph of live and dried specimens; basic information on size, habitat, biology, fisheries, human consumption, market value and trade; geographic distribution maps. The volume is fully indexed and contains an introduction, a glossary, simplified dichotomous keys to live animals and dried products and a dedicated bibliography. Readers are encouraged to base their identifications on a combination of morphological features, samples of ossicles from different body parts and information on what habitat and locality the species was found. -
Book (stand-alone)Putting into practice an ecosystem approach to managing sea cucumber fisheries 2010
Also available in:
No results found.Boom-and-bust cycles are commonplace in the exploitation history of sea cucumber fisheries but pandemic overfishing to critical levels now threatens the persistence of breeding stocks for future generations of coastal fishers. Resource managers must embrace an ecosystem approach to fisheries, in which biodiversity conservation, ecosystem services and the concerns of stakeholders are taken into account alongside of the productivity of stocks and the economic gains from fishing. This document is an abridged version of FAO Fisheries and Aquaculture Technical Paper No. 520 Managing Sea Cucumber Fisheries with an Ecosystem Approach. This booklet provides a “roadmap” for developing and implementing better management of sea cucumber fisheries. A set of management regulations and actions by the resource manager are needed in all fisheries and will depend on the way in which animals are fished, the status of stocks, and the technical and human resource capacity of management institutions. Als o summarised here are the merits and limitations of potential management regulations and actions by the resource manager, and steps required for their implementation. -
