摘要

Sportfishing catch and effort were sampled on lakes Michigan, Huron, Erie, andSuperior from April 1, 1992 through March 31, 1993. The objective of the creel monitoring program is to obtain a continuous record of sport catch, catch rates, and catch composition for the Great Lakes and important anadromous river fisheries. Over 79,000 anglers were interviewed at the completion of their fishing trips. Catch and effort estimates were calculated by month for all areas sampled. It was estimated that anglers spent 5.9 million angler hours in all areas of the Michigan waters of the Great Lakes that were surveyed. Total harvest was estimated to be over 4.3 million fish. Yellow perch were the most abundant species in the sport catch in most sample areas, totaling 3.4 million fish. In addition to yellow perch, sport anglers harvested an estimated 324,000 walleye, 76,000 chinook salmon, 75,000 lake trout, 51,000 rainbow trout, 49,000 coho salmon, and 14,000 brown trout.
