Description: The population status of cutthroat trout Oncorhynchus clarki at Neck Lake in Southeast Alaska was examined from 1996 through 1998 in response to angler concerns about restrictive harvest regulations and the potential effects of introduced coho salmon Oncorhynchus kisutch on the trout population. Sampling in 1996, 1997, and 1998 (twice) permitted use of a Jolly-Seber (JS) model to estimate abundance in 1997 and 1998. Also, a two-event (Petersen/Darroch) closed population (CP) model was used to estimate abundance in 1998. An estimated 2,982 (SE = 232) cutthroat trout were present in 1997; 2,742 (SE = 243) were present in mid-May 1998 under the JS model, and 3,151 (SE = 144) were present in May 1998 under the CP model.
