Biology and Culture of Portunid Crabs of World Seas provides an abundance of valuable first-hand information about the diversity, biology, ecology culture of the portunid crabs of the word seas. Marine crabs play an important role directly or indirectly in the livelihood of millions of people around the world. They have been reported to make up about 20% of all marine crustaceans caught, farmed, and consumed worldwide. Among these marine crabs, portunid crabs or swimming crabs of the family Portunidae (Class: Crustacea; Order: Decapoda; Infraorder: Brachyura) assume greater significance in the marine industry owing to their delicate meat with nutritional qualities. Although, several species of portunid crabs are edible and commercially important, only a few species of Scylla and Portunus have been widely cultivated. This is largely due to the lack of information on the biology of portunid crabs. Keeping this in view, this new volume presents the biology and aquaculture of marine portunid crabs. This volume will be of great use for researchers and students of disciplines such as fisheries science, marine biology, aquatic biology and fisheries and zoology and will also serve as a standard reference for college, university, and research libraries around the world.

The ocean is a source of unique natural products, mainly accumulated in living organisms. The c.4000 species of tunicates or sea squirts (Phylum, Chordata; Subphylum, Urochordata) are a high-potential yet under-studied source of bioactive compounds for pharmaceuticals. The secondary metabolites such as alkaloids isolated from these organisms have led to the discovery of an approved anti-tumor drug, anti-cancer drugs Yondelis® and Aplidin®, as well as many others in clinical trial. There is an urgent need for more research on the bioactive compounds of marine tunicates and better knowledge about the identification and biology of these species. This is the first focused book to meet this need. The taxonomy, common name, global distribution, habitat, diagnostic features and pharmaceutical compounds (along with their activities) of 165 key species of tunicates are given, with high-quality illustrations. Contributed by scientists of both Marine Biology and Pharmacy disciplines, this book will serve as a standard reference for researchers, teachers and students of Fisheries Science, Marine Biology, Life Sciences, Biotechnology, Natural Products, and Pharmacy, and as a valuable guide for pharmaceutical companies involved in the development of new drugs from marine organisms.

This enlightening new volume details over 200 species of bioluminescent marine fishes along with their biotechnological and therapeutic applications. It delves into the chemistry, diversity, biology, and functions of these fishes. Bioluminescence, which is a type of chemiluminescence and is a "cold living light," is seen in a wide variety of organisms from bacteria to fish. The chemicals and circumstances of this phenomenon are used for biotechnological, commercial, and therapeutic applications. Bioluminescence imaging technology has provided valuable means for the monitoring of different biological processes for immunology, oncology, virology, and neuroscience. A new emerging biological technique that combines luminescence with optogenetics involves the use of light to control cells, particularly neurons, in living tissue. Bioluminescence may also be as a potential form of green energy. The author states that more than 75% of deep-sea creatures (700 marine genera within 16 phyla) have been estimated to possess this phenomenon of bioluminescence. While marine plants do not display bioluminescence, several organisms such as the dinoflagellate, cnidarian, jellyfish, ostracod crustacean, molluscan squids and lantern fish are well known for their luminescence. Bioluminescence is employed by marine organisms mainly to hunt their prey, to defend against predators and in reproduction. This scientifically comprehensive and well-illustrated book will serve as an essential standard reference for students and teachers as well as marine biologists, fisheries scientists, zoologists, and environmentalists.

The first comprehensive volume exclusively on marine cone snails, this book provides descriptions of over 100 species of hazardous marine snails along with their biological and ecological characteristics; the characteristics of conotoxins; information on cone snail injuries and their treatment along with prevention measures; and the therapeutic and medicinal value of conotoxins, including as a powerful nonaddictive painkiller, an epilepsy drug, and more. Over 275 color illustrations accompany the text for easy identification.

This comprehensive volume focuses exclusively on sea snails (or gastropods), which are popular food items and occupy an important role in the commercial shell craft industry. Familiar examples include conchs (highly sought after due to their mild flavor) and escargot, abalone, and periwinkle snails. This book covers the profile (habitat, distribution, morphology, food and feeding, reproduction, conservation status, etc.) of about 180 species of commercial edible marine gastropod molluscs as well as their nutritional values, commercial importance, and pharmaceutical value. Also included is information on their prevalent diseases and parasites. The informative descriptions are presented in an easy-to-read style with neat illustrations.

This comprehensive volume provides a plethora of first-hand information on the diversity, biology, and ecology of edible marine bivalve molluscs. It covers the biology of edible marine bivalves; profiles about 180 species, providing information on their habitat, distribution, morphology, food and feeding, reproduction, conservation status, etc.; discusses their nutritional values; examines their pharmaceutical value; and looks at their diseases and parasites. This abundance of knowledge is presented in an easy-to-read style with informative illustrations. Marine bivalve molluscs play important roles in the marine ecosystems by filtering water and serving as habitat and prey for a variety of sea life. This diverse group of species, estimated at around 9,200, inhabits virtually the entire world’s oceans, from the balmy tropics to the sub-zero Arctic, and from deep oceans to sandy and rocky shorelines. Among the marine bivalves, a total of 180 species (including mussels, oysters, scallops, cockles, and clams) have long been a part of the diet of coastal human populations. Many species of marine bivalves are also commercially important for other purposes, such as pearls and shells for jewelry and decoration. The volume, part of the Biology and Ecology of Marine Life book series, will be of great use to students and researchers in fisheries science, marine biology, aquatic biology, and zoology.

Here is a first-of-its-kind volume on the biology and ecology of venomous and traumatogenic freshwater and marine catfishes. This comprehensive volume first provides an introduction to venomous catfish families and then goes on to describe and explain their diversity, species, characteristics, geographical distribution, venomous symptoms, ecology, and the pharmaceutical value of catfish venoms. Catfish form an important group of fishes with many different roles, including as food, as ornamental fishes, and for sport fishing. Catfish are found to be distributed worldwide but are most abundantly distributed in the tropics of Asia, Africa, and South America. Like jellyfish, scorpions, and snakes, several species of catfish have been reported to be venomous with their painful stings. The major groups of persons at risk for catfish envenomation are fishermen and water sports participants. It is estimated that 1625 species of catfish are venomous although this has been studied for only 158 species. While some species of catfish cause mild envenomation, several species have been reported to cause severe envenomation associated with secondary bacterial infections. The symptoms related to catfish envenomation include local intense pain, edema, erythema, paleness, and cutaneous necrosis. Notable species of catfish causing serious envenomations include the Arabian Gulf catfish (Arius thalassinus), Carolina madtom (Noturus furiosus), and Oriental catfish (Plotosus lineatus). Providing extensive information, this volume serves as a text and reference for students and researchers of several disciplines, such as marine biology, fisheries science, and aquatic biology; as a guide for physicians and environmentalists; and as a valuable reference book for marine libraries of colleges and universities.

This comprehensive book provides first-hand information on the diversity, biology, and ecology of venomous stingrays of freshwater, brackish, and marine ecosystems. Each year thousands of injuries to swimmers and surfers are reported, with 750 to 1,500 stingray injuries reported each year in the US alone. As more vacationers spend their leisure time exploring coasts and tropical reefs, often in isolated areas without immediate access to advanced health care, there will be greater potential for stingray injuries. A thorough understanding about the diversity of stingrays of marine and freshwater ecosystems and their injuries and envenomations would largely improve the public health community’s ability to better manage and to prevent stingray injuries. This volume fills that gap. With over 200 photos and illustrations, this book shows the characteristics of venomous stingray families along with other profile information, such as common name, geographical distribution, diagnostic features, reproduction, predators, parasites, the International Union for Conservation of Nature’s conservation status. Importantly, it includes valuable information on stingray injuries, envenomation, and medical management. This volume will be very informative for students of fisheries science, marine biology, aquatic biology, and environmental sciences, and will become a standard reference for marine professionals, health practitioners, and college and university libraries, and as a helpful on-board
