This book was released on 2003 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resident coastal cutthroat trout Oncorhynchus clarki clarki population in Florence Lake, Southeast Alaska was sampled from July through October, 1997 to assess its maturity, fecundity, growth and sustained yield. Maturing female cutthroat have significant gonad development between mid September and late October. A gonadosomatic index threshold was established for female cutthroat trout. A logistic model for maturity estimated asymptotic percentages by age and length: 92% and 100% for males and 86% and 80% for females, indicating presence of skip spawning. Male cutthroat trout matured earlier and at smaller length than females, but females matured more rapidly. An allometric model fitted fecundity data well. Schnute's growth model indicated that growth was relatively slow. An ll-inch (279 mm) minimum size limit allows a high proportion of trout at Florence Lake to spawn at least once. Age-based and length-based per recruit analyses performed comparably and established sustainable fishing mortality estimates.

This book was released on 2016 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A two-event mark-recapture study was conducted during 2002 at Florence Lake in Southeast Alaska to estimate the abundance and length composition of coastal cutthroat trout Oncorhynchus clarki clarki. Fish were captured with hook and line gear and hoop traps, marked with t-bar anchor tags, and given a dye mark as a secondary mark. The pooled Petersen estimate of abundance of cutthroat trout =180 mm FL was 13,515 fish (SE = 1,010; 95% CI = 11,534 - 15,495). Most of the cutthroat trout =180 mm FL were estimated to be =300 mm FL ( = 0.987, SE = 0.054). A much smaller proportion were 301-360 mm FL ( = 0.02, SE = 0.006), and very few fish were =360 mm FL ( = 0.005, SE = 0.002). Although the Petersen estimate was biased, abundance estimates and length composition of large and small fish were relatively similar to estimates from 1994 and 2003
