For their great commercial importance as a human food delicacy, crayfish are now becoming of wider interest to molecular biologists, and also to conservationists due to the fact that in some countries many of the native crayfish species are under threat from human activity, disease, and competition from other introduced crayfish species.

Book Description
Crayfish are one of the most iconic freshwater crustacean groups of the world. The wide range of biological adaptations of the freshwater crayfish to the limnetic ecosystems is surprising, as is there is high potential of some taxa to become invasive species. There is a constant growing interest in develop research with freshwater crayfish. They can be an important food source in several countries, the aquarium pet trade and cultural importance, in addition to the presence of several imperiled species. This book brings important reviews of some aspects of diversity, biological features, evolution, habitat characteristics, behavior and conservation strategies of freshwater crayfish, including native taxa, especially endemic from South America, New Guinea and North America, and non-indigenous species. In South American, new species have been discovered in recent years and are classified in threat categories, indicating the need of more studies regarding taxonomy and conservation. For New Guinean species, data about their exploitation by humans and further perspectives about the improvement of conservation practices are presented. In relation to the North American crayfish, this book brings information about some aspects of biology and behavior of the burrowing species Procambarus acanthophorus. A global assessment and future perspectives for all alien crayfish species are also presented in this book. Regarding the partenogenetic marbled crayfish, Procambarus virginalis, the book brings an extensive review covering aspects of detection history, biology, ecology, evolution, systematics and utilization of this species in the world. In additon, an overview of integrative taxonomy studies and cryptic diversity in crayfish is also presented

Book Description
"This publication describes Australia's Euastacus crayfish, the largest of the 10 genera of Australian freshwater crayfish. We cover the full 50 Euastacus species found in Australia, from the iconic giant Murray lobsters (Euastacus armatus), which are recreationally fished, to the exceedingly rare tiny species, like Euastacus maidae from the New South Wales-Queensland coastal border region ... The Euastacus crayfish are referred to as 'spiny crayfish' because they have impressive arrays of spines on their hard armoured shells."--Preface.

Book Description
Sumerged aquatic plants limit the suitability for trout management of many shallow lakes in the Southwest. Control of these weeds has been achieved by the introduced crayfish Orconectes causeyi. The life history, ecology, and weed-control activities of the crayfish are discussed. Abundant crayfish populations occur over a wide range of elevations in permanent well-oxygenated ponds, lakes and streams where predaceous warm-water fishes are scarce. Weed control is proportional to the crayfish population and proximity of a rocky substrate which is preferred habitat. This crayfish is a tertiary burrower establishing relatively shallow burrows for hibernation and egg hatching periods. It has not damaged dams or irrigation ditches and has been compatible with local agriculture.

Book Description
Crayfish are the largest, mobile freshwater invertebrates with some 540 recognised species. They are of long standing interest to anatomists and physiologists. For their great commercial importance as a human food delicacy, crayfish are now becoming of wider interest to molecular biologists, and also to conservationists due to the fact that in some countries many of the native crayfish species are under threat from human activity, disease, and competition from other introduced crayfish species. This fully comprehensive book covers all major aspects of these important animals, including taxonomy, anatomy, evolution, growth and reproduction, behaviour, ecology, physiology, conservation, genetics, immunology, environmental aspects, and diseases. There are separate chapters on each genus of crayfish of commercial importance. Written by 22 well-known experts, Biology of Freshwater Crayfish has been carefully edited by David Holdich, internationally recognised for his work with these animals. The book is an essential purchase for anyone involved with the biology or exploitation of crayfish, including freshwater and invertebrate biologists and personnel involved in fisheries and aquaculture. Libraries in all universities and research establishments where biological sciences, fisheries or aquaculture are studied or taught should have copies of this important book on their shelves.
