This book provides a comprehensive and current source of information on fishes--including systematics, zoogeography, behavior, and conservation of fishes--that is often needed by professionals as background for writing accurate reports. This book covers the structure and physiology, evolution and taxonomy, zoogeography, and ecology and conservation of fishes. For fisheries biologists, conservation biologists, and aquatic ecologists that need an up-to-date reference on Ichthyology.

Anders Halverson provides an exhaustively researched and grippingly rendered account of the rainbow trout and why it has become the most commonly stocked and controversial freshwater fish in the United States. Discovered in the remote waters of northern California, rainbow trout have been artificially propagated and distributed for more than 130 years by government officials eager to present Americans with an opportunity to get back to nature by going fishing. Proudly dubbed "an entirely synthetic fish" by fisheries managers, the rainbow trout has been introduced into every state and...

From the fifty-one-foot whale shark Rhincodon typus to a less-than-one-half-inch fish in the minnow family--the tiny Paedocypris progenetica--fish certainly carry a lot of weight . . . or do they?

A fish's heft in water may vary, but these diverse aquatic animals certainly carry a lot of weight in our ecosystems and environment. From freshwater to ocean habitats, Judith S. Weis offers a fascinating look at these deceptively simple creatures. Fishes may appear to live a dull existence, but appearances change once we understand more about how they survive. These wonders...

If you travel the open ocean anywhere in the tropics, you are very likely to see flyingfish. These beautifully colored "ocean butterflies" shoot out of the water and sail on majestic, winglike pectoral fins to escape from predators such as dolphins, swordfish, and tuna. Some can travel for more than six hundred feet per flight. Yet despite their prevalence in warm ocean waters and their vital role in the tropical food chain, surprisingly little is known about flyingfish--more than 60 species are said to exist, but nobody is sure of the number. This beautifully illustrated book presents...

Exploring what he considers to be the outstanding aspects of fish biology, Mr. Marshall surveys the present knowledge in the field and suggests possibilities for future investigation.

He considers the causes of the overwhelming predominance of the teleost fishes, discusses the biology of deep-sea fishes, and studies such aspects of dynamic design as body form, fin pattern, muscular organization, and certain neural features in relation to movement and water.

His last chapter, on convergent evolution, deals with convergences among fishes as well as with...
