Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids, and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

The use of wildlife for food and other human needs poses one of the greatest threats to the conservation of biodiversity. Wildlife exploitation is also critically important to many people from a variety of cultures for subsistence and commerce. This book brings together international experts to examine interactions between the biology of wildlife and the divergent goals of people involved in hunting, fishing, gathering and culling wildlife. Reviews of theory show how sustainable exploitation is tied to the study of population dynamics, with direct links to reproductive rates, life histories, behaviour and ecology. As such theory is rarely put into practice to achieve sustainable use and effective conservation, Conservation of Exploited Species explores the many reasons for this failure and considers remedies to tackle them, including scientific issues such as how to incorporate uncertainty into estimations, as well as social and political problems that stem from conflicting goals in exploitation.

Investigation of Missing & Exploited Children: The Gateway of Child Sex Trafficking is designed to provide the essential knowledge needed to identify and understand the issues and solutions that effectively combat the evils of domestic child sex trafficking in the United States. It is both an instructional guide and a resource manual for both the citizen and the government manager. The approach is direct and concise, which facilitates comprehension by novices as well as experienced public servants. The purpose of this book is to fill the existing need within the field of public and private prevention/investigation of runaways for a precise, comprehensive manual detailing the elements necessary for the elimination of turning vulnerable children into sex slaves. There is a lack of professional resources on preventing child sex trafficking currently available. Investigation of Missing & Exploited Children: The Gateway of Child Sex Trafficking will help fill this void

The book comprises country reports of the 10 new EU Member States. Each country report provides essential definitional information regarding the various forms of sexual exploitation of children and types of missing children, outlines the way data collection on sexual exploited and missing children by various governmental (police, judicial, other) and nongovernmental actors is organised, and delivers available data on the phenomena concerned. A final, comparative report bridges the country report information into a first epidemiological state of the art for the 10 new Member States and for the entire enlarged EU, comparing the newly gathered information with information collected in the initial 15 Member States during a previous study, the report of which has been published in January 2004 as the first book in the Childoscope series.
