Immunity studies in sharks over the past three decades have produced some remarkable discoveries. If one message rings true, it is that alternative animal model systems, such as sharks and their relatives, have contributed very substantially to a better understanding of the development evolution of our own immune system.

Immunobiology of the Shark describes the cellular, genetic, and molecular specifics of immune systems in sharks. Diverse approaches were employed to study the immunobiology of the shark from basic microscopic observations to detailed genome...

Fish constitute an important natural renewable resource and any reduction in their ability to propagate as a result of human interference may have significant socioeconomic consequences. The negative effect of human activity on sex differentiation and reproductive output in fish is so diverse that it has been difficult to encompass it in a single book. This book serves as the first attempt to do so.

Unlike in mammals, the expression of a host of sex differentiation genes in fish is mostly controlled by environmental factors. Not surprisingly, environmental sex differentiation is...

The darters are a fascinating group of colorful and diminutive freshwater fish whose beauty rivals that of the tropical reef fishes. Native only to North America, the darters occur widely, especially in the United States, but are little known to the general public, largely because of their small size -- few exceed six inches and some measure a mere one inch at maturity.

This book is the first comprehensive guide to the darters, covering all named and several undescribed forms -- 140 species in all. Each species account includes a synoptic description to aid in separation of similar...

Atlantic salmon (Salmo salar, L) is an anadromous species contributing to major fishery catches and comprising a significant part of the aquaculturally produced fish for human consumption. The aim of this book is to incite the interest in the field of knowledge gathered from a broad scope of disciplines that have investigated this fish species. Undeniably, increasing fishery pressure on wild fish stocks throughout the world oceans has prompted the need for sustainable aquacultural production for increasing human demands.

Generously illustrated, this essential handbook for herpetologists, ecologists, and naturalists features comprehensive keys to eggs, embryos, salamander larvae, and tadpoles; species accounts; a glossary of terms; and an extensive bibliography. The taxonomic accounts include a summarization of the morphology and basic natural history, as well as an introduction to published information for each species. Tadpole mouthparts exhibit major characteristics used in identifications, and the book includes illustrations for a number of species. Color photographs of larvae of many species are also...

The waters of the Pacific Northwest are home to some of the most unique and diverse marine creatures in the world, including rockfishes, greenlings and, of course, salmon. This full-colour brochure is packed with information on seventy-eight "must-have" common fishes of the Pacific Northwest. A Field Guide to Common Fish of the Pacific Northwest provides a succinct rundown on a huge variety of our fishy neighbours, and is an ideal guide for fishermen, divers and anyone interested in the marine life that fills our surrounding waters.
