Biology, management, and culture of walleye and sauger.
Empirical findings about the fish are presented along with speculative or theoretical discussions designed to stimulate and guide future research. The 13 studies update and supplant an earlier reference published by the Food and Agriculture Organization sometime during the 1990s. The topics include a phylogenetic analysis of Percidae using osteology, the distribution and population genetics of walleye and sauger, reproductive and environmental biology, feeding ecology and energies, harvest regulations and sampling, and lessons learned over the past century on stocking and marking. The reference will be useful to researchers or fishery personnel. (Annotation ©2011 Book News Inc. Portland, OR)
Invasive Asian carps in North America; proceedings.
Population surges in four species of Asian carp have caused ecological and economic damage as they compete with native fish populations and cause changes in water quality in the US and Canada, especially in the Mississippi River Basin. This collection of updated papers from an August 2006 symposium sheds light on the biology, effects, and management of Asian carp. The book also contains research completed since 2006, for a total of 17 chapters. Early chapters give the history of the government's involvement in promoting the use of Asian carp and detail the latest methods for assessing the biological risk of Asian carp. Later chapters cover topics such as alternative methods for snail control in aquaculture ponds, a heuristic tool for predicting dispersal of bighead carp in the Mississippi River system, an electric fish dispersal barrier in the Chicago Sanitary and Ship Canal, and a theoretical strategy for eradication of Asian carp using a Trojan Y chromosome to shift the sex ratio of the population. The book contains b&w images and maps, plus a few in color. Chapman is affiliated with the US Geological Survey's Columbia Environmental Research Center.
