Available in PDF, EPUB and Kindle. Book excerpt: A multiple event capture-recapture study of rainbow trout, Oncorhynchus mykiss, in the upper Kenai River was conducted in 2001 as a result of concerns that mortality from catch-and-release fishing might be jeopardizing sustainability of the resource. The objectives of the study were to estimate the abundance and length composition of rainbow trout in the most heavily fished section of the upper Kenai River, from river mile 69.7-73.2.

Book excerpt: A multiple-event mark–recapture study was conducted on rainbow trout (Oncorhynchus mykiss) in the upper Kenai River in 2018. The objectives of this study were to estimate the abundance and fork length (FL) composition of rainbow trout in the most heavily fished section of the upper Kenai River (river miles 69.6–73.2) and to compare these estimates to those from previous surveys conducted in 1986, 1987, 1995, 2001, and 2009 on the same stretch of river. There were an estimated 10,568 (SE 608) rainbow trout at least 200 mm FL and 8,482 (SE 495) rainbow trout at least 300 mm FL in the study area. Abundance of fish at least 200 mm FL was 79% higher than in 2009 and 24% higher than in 2001. Abundance of fish at least 300 mm FL was 66% higher than in 2009, 33% higher than in 2001, and 52% higher than in 1995. Most of the rainbow trout were between 250 mm and 449 mm FL, accounting for 88% of the population. Approximately 75% of the population was less than 400 mm FL, which is the approximate upper length (16 inches total length) of fish allowed to be harvested by regulation. Overall, rainbow trout abundance in 2018 was considerably higher than in any other study year, but the number of fish more than 450 mm FL was only 743 (SE 71), which was less than half of what was observed in 1995, 2001, and 2009.

Available in PDF, EPUB and Kindle. Book excerpt: A two-event mark-recapture experiment was conducted for the Kisaralik River rainbow trout population in 2011. Sampling took place in a 68-rkm section starting from Golden Gate Falls and continuing downstream to the lower boundary of the Yukon Delta National Wildlife Refuge. The first event occurred from 16 to 22 July and the second event from 6 to 12 August. A Bailey-modified Petersen estimator was used to estimate the abundance of rainbow trout =350 mm fork length (FL). The estimate omitted the bottom 13 rkm of the planned study area due to inadequate sample sizes attributed to poor water conditions during the recapture event. The estimated abundance of rainbow trout =350 mm FL for a 55-rkm section of the river immediately below Golden Gate Falls was of 3,959 (SE=651; 95% CI=2,683-5,235). Although the abundance estimate of this study ended up not being directly comparable to the 1997 estimate, they appear to be similar in terms of densities. Estimated length composition for the truncated study area had no dominant 25-mm FL length categories with five length categories (350-374, 375-399, 400-424, 425-449 and 450-474) all comprising between 14% and 20% of the population. Cumulative length frequencies of fish sampled in 1997 and 2011 were significantly different (P
