Book Description
This publication contains current information on the status of world sea cucumber resources and use, focusing on established countries such as China, Ecuador, Indonesia, Japan, Malaysia and the Philippines, as well as relative newcomers to the sector such as Cuba, Egypt, Madagascar and Tanzania. Issues discussed include technical advances in artificial reproduction and farming of selected commercial species; and the report includes the recommendations of a FAO workshop on cucumber aquaculture and management, held in China, in October 2003.

Book Description
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 booklet provides a "roadmap" for developing and implementing better management of sea cucumber fisheries.--Publisher's description.

Book Description
"Sea cucumbers are important resources for coastal livelihoods in more than 40 countries. Sadly, widespread overexploitation of wild stocks risks biodiversity loss and the long-term viability of fisheries. Spawned from an FAO international workshop of experts, this document presents a 'roadmap' to guide fishery managers in choosing appropriate regulatory measures and management actions for sea cucumber fisheries. It elaborates on their use, limitations and modes of implementation, with examples and lessons learned from various fisheries. Achieving sustainable management of sea cucumber fisheries requires an ecosystem approach to fisheries (EAF), precautionary regulations, improved enforcement and stronger commitment of fishery managers and policy-makers"--Publisher's description

Book Description
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.
