Mortality of lesser scaup (Aythya affinis) from commercial trotlines was studied on Lake Okeechobee, Florida, from November 1985 to March 1986. Of 27 scaup removed from 118 trotlines, 81% were hooked in body parts other than the mouth. An estimated 7,458 scaup, or 8% of the estimated average winter population of 97,071, were killed during 5,675 man-days of fishing. Potential impacts on scaup populations are discussed.
Duck migration chronology was determined for 11 national wildlife refuges (NWRs) in Florida during 1976-81. Mean monthly population indices differed by month, with peak populations occurring in December. Extension of the duck hunting season framework until 31 January, with a concurrent reduction of season days in December probably would reduce the statewide duck harvest. Implications of this harvest strategy are discussed in terms of hunter satisfaction and possible duck population impacts.
The Journal of the Southeastern Association of Fish and Wildlife Agencies presents papers that cover all aspects of the management and conservation of inland, estuarine, and marine fisheries and wildlife. It aims to provide a forum where fisheries and wildlife managers can find innovative solutions to the problems facing our natural resources in the 21st century.
