Admixture analysis of stocked brown trout populations using mapped microsatellite DNA markers: indigenous trout persist in introgressed populations.
Admixture between wild and captive populations is an increasing concern in conservation biology. Understanding the extent of admixture and the processes involved requires identification of admixed and non-admixed individuals. This can be achieved by statistical methods employing Bayesian clustering, but resolution is low if genetic differentiation is weak. Here, we analyse stocked brown trout p...

متن کاملUse of Outlet Barriers to Prevent Fall Emigration of Brook Trout Stocked in Adirondack Lakes
—Outlet barriers in stocked lakes of the Adirondack Mountains were used to test the hypothesis that preventing fall emigration by adult brook trout Salvelinus fontinalis would increase trap-net and angling catch rates as well as the number of large trophy fish. Outlet barriers were maintained during the fall spawning season for 6 years on one lake and 10 years on another lake. We compared preba...
متن کاملVariation in angler distribution and catch rates of stocked rainbow trout in a small reservoir
We investigated the spatial and temporal relationship of catch rates and angler party location for two days following a publicly announced put-and-take stocking of rainbow trout (Oncorhynchus mykiss). Catch rates declined with time since stocking and distance from stocking. We hypothesized that opportunity for high catch rates would cause anglers to fish near the stocking location and disperse ...
متن کاملThermal Stress and Predation: Influences on the Structure of a Gull Colony and Possibly on Breeding Distributions
-The arrangement of nesting territories of Larus occidentalis livens on beaches is commonly linear, and most territories are adjacent to water. This arrangement differs from clustered colonies typical of most gulls. Two hypotheses are advanced to explain this unusual nest arrangement: it may provide access to the intertidal zone for foraging or access to water for thermoregulation. Foraging act...
