Book (series)Advances in sea cucumber aquaculture and management 2004
Also available in:
No results found.The utilization of sea cucumbers for human consumption and other uses has been steadily growing over the years. Up-to-date information on the present status of world sea cucumber resources and utilization is presented with special focus on those countries such as China PR, Ecuador, Indonesia, Japan, Malaysia and the Philippines which have been heavily engaged in the industry for decades. Information from other countries such as Cuba, Egypt, Madagascar and Tanzania, relative new comers to the sec tor, is also provided indicating to some extent the growing interest with regards to the exploitation of holothurians for the demanding Asian markets. Information on technical advances made in the artificial reproduction and farming of selected commercial species is presented. This document includes the recommendations formulated during the FAO Workshop on Advances in Sea Cucumber Aquaculture and Management (ASCAM) held in Dalian, People's Republic of China, in October 2003, along with the techn ical papers presented. The report will be useful to those international and regional development organizations and national governments who wish to prioritize their activities concerning sea cucumber conservation and exploitation. -
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 (series)A guide to northern sea cucumbers
The biology and management of Cucumaria frondosa
2023Also available in:
No results found.This document synthesising knowledge on the northern sea cucumber Cucumaria frondosa was prepared for all stakeholders, including industry participants, government scientists, policymakers, and academic researchers. Its aim is to highlight the uniqueness of this marine resource to guide the industry forward and to emphasize areas that deserve further investigation. Available data from eastern and northern Canada, eastern United States of America, Greenland, northern Europe and the Russian Federation are presented. Topics covered include the taxonomy, distribution, biology, and ecology of the species, the natural threats it faces, the current harvesting, processing and marketing practices, and the prospects for aquaculture development. Relying on a knowledge base gathered over more than 40 years, this contribution compares C. frondosa with other common commercial species of sea cucumbers to tease out the major aspects that set it apart. A final section provides a number of key recommendations for its management and conservation.
