Book Description
Channel Catfish are widely distributed across North America and highly valued as a sport fish and for food. While most Channel Catfish fisheries are managed under liberal harvest regulations, the Red River of the North (Red River) in Manitoba, Canada is managed with restrictive harvest regulations to promote a trophy fishery. Two barriers (dams) are present on the main stem of the Red River and may fragment the population to some degree. My objectives were to: 1) analyze population dynamics of the trophy Channel Catfish population on the lower Red River, 2) compare population characteristics of Channel Catfish in selected reaches throughout the Red River in Manitoba, and 3) determine movement characteristics of Channel Catfish and the permeability of a dam on the lower Red River. We compared our results to the most recent studies on Channel Catfish in the Red River, and also to range-wide age, growth, and mortality statistics. Channel Catfish in the lower Red River commonly reached ages > 20, grew slowly, and had a low mortality rate. Trophy Channel Catfish were most abundant below the dam on the lower river. The size structure within the most upstream reaches we studied were predominantly comprised of small- and intermediate-sized Channel Catfish. We determined the dam is passable by large Channel Catfish (>600 mm), but may be an impediment to small Channel Catfish. My mark-recapture data indicated Channel Catfish can move long distances, where upstream movements > 500 kilometers were common for large Channel Catfish. This research provides insight into the age, growth, and mortality of a trophy fishery for Channel Catfish. We believe restrictive harvest regulations are adequately maintaining the desired age structure and size structure of Channel Catfish in the lower Red River and by consequence, sustaining one of the premier fisheries in North America.

Book Description
Dramatic changes have occurred in the functioning of larger rivers because of social values and policies, land use, inchannel causes, and alien species. These changes have resulted in the reduction in range and abundance of many native fish species. This book describes the historical changes observed in the fish assemblages of 27 large rivers in North, Central, and South America. A synthesizing chapter highlights common and distinct patterns among the rivers and their stressors. The book focuses on entire fish assemblages, including the many species that do not enter fisheries. It will be of interest to both fishery biologists and aquatic ecologists who are concerned with the status and trends in biodiversity and biointegrity. Contains historical information as well as new research and monitoring results, including research on metapopulations, genetics, and life history strategies.
