Review: A Guide to California's Freshwater Fishes By Bob Madgic; Illustrated by William L. Crary. Reviewed by Ryder W. Miller The Aquarium of the Bay, San Francisco, USA Bob Madgic.

US$19.95 Out of sight and therefore out of mind, except perhaps when an angler is interested in catching a meal, freshwater fish swim through perilous, degraded and often polluted waters. Once truly wild, some fish species, like the salmon, are also approaching domesticated status due to the reliance on hatchery release programs. Wet, smelly and often cold, fish and their preservation and protection may offer a challenge to conservationists, who have an easier time with the warm fuzzy things we don't want to eat. Intended as a book for the lay person, A Guide To California's Freshwater Fishes by author and conservationist Dr. Bob Madgic and illustrator William L. Crary succeeds in clearly telling the sad history of California freshwater fishes, celebrating the diversity of freshwater fish that exists in the golden state, and relaying the efforts needed to protect them. As Madgic points out, fish are the most important indicator of aquatic diversity; they signal the health of our waterways, and therefore in some ways the state of the planet. Madgic notes that California's history is reflected in the changing status of its fishes. (p. 7) Madgic begins by telling the long, bleak story of what has happened to the California fish stock, which used to be one of the world's richest. Millions of salmon once migrated up the state's rivers to spawn. As Madgic relays, In California's inland waters resided some of the most beautiful fish imaginable- -the state's native trout species. (p. 11) But California's freshwater fish are in trouble. Two-thirds of the 116 native California fishes are now species of special concern. Sixty-six of these species are endemic to the state. Declines have been due to habitat destruction and introduced species. Florida is the only state with more introduced species than California. Introductions of fish for fishing stock, and the desire to stock any fish species in any available water, led to the demise of the local fish, in some cases extirpation of the native fish species. The problem was compounded by agriculture, which consumed a large majority of the state's water supply. The Department of Fish and Game was also a

Crary专门为非专业人士准备的一本书，《加利福尼亚淡水鱼指南》成功地清楚地讲述了加利福尼亚淡水鱼的悲惨历史，庆祝了加利福尼亚淡水鱼的多样性黄金状态，并传递保护它们所需的努力。正如Madgic指出的，鱼类是水生生物多样性的最重要指标。它们表示我们水道的健康，并因此以某种方式表示地球的状态。 Madgic指出，加利福尼亚州的历史反映在其鱼类状况的变化中。 （第7页）Madgic首先讲了一个漫长而凄凉的故事，讲述加州鱼类种群曾经是世界上最丰富的鱼类种群之一。数百万的鲑鱼曾经迁移到该州的河流中产卵。作为Madgic的接力者，在加利福尼亚的内陆水域栖息着一些可以想象得到的最美丽的鱼类-该州的本地鳟鱼物种。 （第11页）但是加利福尼亚的淡水鱼遇到了麻烦。现在，在116种加利福尼亚本地鱼类中，有三分之二是值得特别关注的物种。这些物种中有66种是该州特有的。数量下降的原因是栖息地遭到破坏和引进物种。佛罗里达州是唯一引进物种比加利福尼亚州更多的州。引进鱼类作为捕捞鱼类，并渴望在任何可用的水中捕捞任何鱼类，这导致了当地鱼类的灭绝，在某些情况下还消灭了本地鱼类。农业使该问题更加复杂，农业消耗了该州大部分的水。鱼和野味部也是
