Book Description
The World of Sea Cucumbers: Challenges, Advances, and Innovations provides broad coverage of sea cucumber biology, ecology, fisheries, aquaculture, and trade while also bringing forward novel cultural, socioeconomic and scientific topics related to commercial and non-commercial species worldwide. Written by international experts in their respective fields, the book offers a unique outlook into the fascinating world of sea cucumbers while also providing valuable information to various stakeholders and researchers. Commercial fisheries and aquaculture programs are addressed, especially as they relate to emerging species, but the book also covers novel, understudied or lesser-known biological, ecological, and commercial aspects. The involvement of Indigenous peoples and minorities in various community-level initiatives and on the cultural significance/impact of sea cucumbers in many regions are also examined. Finally, breakthroughs and emerging biotechnologies centered on sea cucumbers are presented. Brings together a network of experts covering broad sea cucumber topics, from basic biology and commercial trade to socioeconomic value and novel biotechnologies Offers worldwide coverage, including Asia, the Indo-Pacific, Africa, Northern Europe, North and South America, and the poles Raises global awareness on little-known facts of sea cucumber importance

Book Description
Echinoderms, including feather stars, seastars, brittle stars, sea urchins and sea cucumbers, are some of the most beautiful and interesting animals in the sea. They play an important ecological role and several species of sea urchins and sea cucumbers form the basis of important fisheries. Over 1000 species live in Australian waters, from the shoreline to the depths of the abyssal plain and the tropics to Antarctic waters. Australian Echinoderms is an authoritative account of Australia’s 110 families of echinoderms. It brings together in a single volume comprehensive information on the identification, biology, evolution, ecology and management of these animals for the first time. Richly illustrated with beautiful photographs and written in an accessible style, Australian Echinoderms suits the needs of marine enthusiasts, academics and fisheries managers both in Australia and other geographical areas where echinoderms are studied.

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.

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
The Atlantic Sea Cucumber, Cucumaria frondosa (Echinodermata, Holothuria) is a suspension-feeding sea cucumber found throughout the North Atlantic. Recently, interest has emerged in developing a trawl fishery for this species in Nova Scotia, specifically on the Scotian Shelf. As new fisheries emerge in Canada, precautionary management entails examining underlying genetic structure to inform fisheries stocks. This is also important to follow international efforts from organizations such as the Convention on Biological Diversity (CBD) to characterize and manage biodiversity as a biological resource. Little is known about the population genetics of this species, including connectivity across the North Atlantic. One previous study examined genetic structure of C. frondosa in the North Atlantic using Cytochrome oxidase c subunit 1 (COI) and found evidence of minor structure between Europe and North America, but no regional structuring. When this dataset was augmented with additional individuals and sampling sites in this study, the minor structuring between continents remained, but pairwise Fst values between study sites changed. In addition, my results showed that the way DNA sequence data is trimmed can significantly redistribute haplotypes between study sites, implying the need for more standardized methodology for sequence trimming in future analyses. Regional genetic structuring between the coasts of Atlantic Canada and Iceland was re-assessed with a higher resolution method, Restriction Site-Associated DNA Sequencing (RADseq). Overall, both COI and RADseq analyses supported the hypothesis of one metapopulation of C. frondosa across the North Atlantic, with the RADseq analysis indicating that sea cucumbers off the coasts of Iceland and Atlantic Canada constituted at least two subpopulations. In addition, a minor difference between the study site in NAFO Zone 4X and the remainder of Atlantic Canada was found. Thus, there may be greater amounts of genetic structuring within Cucumaria frondosa on the Scotian Shelf than previously thought. There is also evidence that methodology (e.g. marker selection, sequence trimming, sample size) can impact the results of population genetic analyses. The results of this thesis have established a baseline of population structuring for C. frondosa in the North Atlantic, with at least two subpopulations between North America and Europe, but they also demonstrate the need for standardized methodology for trimming sequence data and even selecting appropriate markers for research questions. This will be important for further work on establishing genetic data as a biological resource and for informing long-term management of fisheries.
