Book Description
Excerpt from The Distribution and Food of the Fishes of Three Wisconsin Lakes in Summer Except for the reconnoissance of Reighard little has been published on the ecology of lake fishes. For several years the writer has been studying the distribution, food, and parasites of the fishes in Wisconsin lakes. In 1916 routine catches were made in Lake Wingra, which is small and shallow (pearse and Achtenberg, During the summer of 1919 the fishes in Green Lake and Lake Mendota were investigated (pearse, The former lake is remarkable for its depth and clearness, the latter for the stagnation of its deeper parts during the summer. In 1920 work was done on three lakes: -lake Pepin, which is a part of the Mississippi River and yet shows typical lacustrine conditions; Lake Michigan, representative of primitive lake habitats for the St. Lawrence drainage; and Lake Geneva, the clearest and deepest lake on the Mississippi drain age. The study of the ecology of the Wisconsin lake fishes has progressed to such a stage that it is now possible to compare the fishes in six different types of lakes. Though this paper deals primarily with the three lakes studied during 1920, it also makes comparisons between all the lakes investigated, and thus gives a general summary of the work. Table I contains data relating to all the lakes considered. The lakes are arranged according to the total volume of water.

Book Description
New York Times Bestseller Winner of the Los Angeles Times Book Prize Winner of the J. Anthony Lukas Award "Nimbly splices together history, science, reporting and personal experiences into a taut and cautiously hopeful narrative.… Egan’s book is bursting with life (and yes, death)." —Robert Moor, New York Times Book Review The Great Lakes—Erie, Huron, Michigan, Ontario, and Superior—hold 20 percent of the world’s supply of surface fresh water and provide sustenance, work, and recreation for tens of millions of Americans. But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

Book Description
Centrarchid fishes, also known as freshwater sunfishes, include such prominent species as the Largemouth Bass, Smallmouth Bass and Bluegill. They are endemic to Eastern North America where they form part of a multi-million dollar sports fishing industry, but they have also been widely introduced around the globe by recreational anglers, in aquaculture programs and by government fisheries agencies. Centrarchid Fishes provides comprehensive coverage of all major aspects of this ecologically and commercially important group of fishes. Coverage includes diversity, ecomorphology, phylogeny and genetics, hybridization, reproduction, early life history and recruitment, feeding and growth, ecology, migrations, bioenergetics, physiology, diseases, aquaculture, fisheries management and conservation. Chapters have been written by well-known and respected scientists and the whole has been drawn together by Professors Cooke and Philipp, themselves extremely well respected in the area of fisheries management and conservation. Centrarchid Fishes is an essential purchase for all fish biologists, ecologists, fisheries managers and fish farm personnel who work with centrarchid species across the globe.
