Members of the phylum Echinodermata are among the most familiar marine invertebrates. Forms such as the sea star have become virtually a symbol of sea life. Used in ancient oriental medicine as a source of bioactive compounds, sea cucumbers, sea stars and sea urchins are now used for the extraction and purification of cytotoxic, haemolytic, antiviral, antifungal, antifouling, antimicrobial and even anti-tumoural activities. In addition, of the five extant classes, sea urchins and sea cucumbers are important economic resources for current fishery and aquaculture. Molecular and cell biological techniques described in this book are, on the one hand, indicative of the improvements made over the years and, on the other, stress the need of their further exploitation for the sustainable production of bioactive compounds and their application in biomedicine.

Echinoderm Research And Diversity In Latin America written by Juan José Alvarado and has been published by Springer Science & Business Media this book supported file pdf, txt, epub, kindle and other format this book has been release on 2012-08-07 with Science categories.

This book compiles for the first time the development of echinoderm research in Latin America. The book contains 17 chapters, one introductory, 15 country chapters, and a final biogeographic analysis. It compiles all the investigations published in international and local journals, reports, theses and other gray literature. Each chapter is composed of 7 sections: introduction describes the marine environments, and main oceanographic characteristics, followed by a history of research account divided by specific subjects. The next section addresses patterns of distribution and diversity. A specific section would explain fishery or aquaculture activities. The next sections deal with environmental and anthropogenic threats that are affecting echinoderm, and any conservation or management action. Finally, a section with conclusions, needs and new lines of research. The book will include two appendixes with species lists of all echinoderms with bathimetric data, habitat and distribution.

Sea urchins and sea cucumbers are highly sought after delicacies growing in popularity globally. The demand for these species is rapidly outpacing natural stocks, and researchers and seafood industry personnel are now looking towards aquaculture as a means of providing a sustainable supply of these organism. Echinoderm Aquaculture is a practical reference on the basic biology and current culture practices for a wide range of geographically diverse echinoderm species. Echinoderm Aquaculture begins by examining the basic ecology and biology of sea urchins and sea cucumbers as well as the breadth of uses of these organisms as a source of food and bioactive compound. Subsequent chapters delineate the specific species of interest invarious geographic regions from around the world. Together, chapters provide a comprehensive coverage of culture practices. Echinoderm Aquaculture is a practical reference for researchers and industry personnel, and will serve as an invaluable resource to this rapidly growing segment of the aquaculture industry.

Echinoderms and prochordates occupy a key position in vertebrate evolution. The genomes of sea urchin share 70% homology with humans. Researches on cell cycle in sea urchin and phagocytosis in asteroids have fetched Nobel Prizes. In this context, this book assumes immense importance. Echinoderms are unique, as their symmetry is bilateral in larvae but pentamerous radial in adults. The latter has eliminated the development of an anterior head and bilateral appendages. Further, the obligate need to face the substratum for locomotion and acquisition of food has eliminated their planktonic and nektonic existence. Egg size, a decisive factor in recruitment, increases with decreasing depths up to 2,000-5,000 m in lecithotrophic asteroids and ophiuroids but remains constant in their planktotrophics. Smaller ( 110 mm) asteroids generate planktotrophic eggs only. Publications on sex ratio of echinoderms indicate the genetic determination of sex at fertilization but those on hybridization, karyotype and ploidy induction do not provide evidence for heterogametism. But the herbivorous echinoids and larvacea with their gonads harboring both germ cells and Nutritive Phagocytes (NPs) have economized the transportation and hormonal costs on gonadal function. Despite the amazing potential just 2 and 3% of echinoderms undergo clonal reproduction and regeneration, respectively. Fission is triggered, when adequate reserve nutrients are accumulated. It is the most prevalent mode of clonal reproduction in holothuroids, asteroids and ophiuroids. However, budding is a more prevalent mode of clonal reproduction in colonial hemichordates and urochordates. In echinoderms, fission and budding eliminate each other. Similarly, autoregulation of early development eliminates clonal reproduction in echinoids and solitary urochordates. In pterobranchs, thaliaceans and ascidians, the repeated and rapid budding leads to colonial formation. Coloniality imposes reductions in species number and body size, generation time and life span, gonad number and fecundity as well as switching from gonochorism to simultaneous hermaphorditism and oviparity to ovoviviparity/viviparity.

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
