Description: A lack of information about cutthroat trout Oncorhynchus clarki in Southeast Alaska prompted an examination of their population status in the Sitkoh Lake drainage on Chichagof Island. A study to estimate abundance and size composition in 1997 using a multi-season Jolly-Seber estimator was conducted from 1996 through 1998. The study was designed such that abundance was also estimated for 1997 using a two-event Petersen closed population estimator. An estimated 1,260 (SE = 221) cutthroat trout 180 mm were present in Sitkoh Lake and upper Sitkoh Creek in 1997 under the Jolly-Seber model, and 1,481 (SE = 262) fish were estimated in Sitkoh Lake with the Petersen model. Only 2 percent of the estimated cutthroat trout population were larger than the minimum 14-in total length limit (336 mm fork length) established for harvest in the sport fishery at Sitkoh Lake.
