Stocking is a common practice throughout the world that may increase hybridization between wild and domesticated populations. Stocking intensity alone does not always fully explain the observed patterns of hybridization, suggesting that the intensity of hybridization may be modulated by environmental factors. Using brook charr (i.e., brook trout, Salvelinus fontinalis) as a model, the objective...

Diet, age, and growth rate influences on fish mercury concentrations were investigated for Arctic char (Salvelinus alpinus) brook trout fontinalis) in lakes of the eastern Canadian Arctic. We hypothesized that faster-growing have lower because dilution, a process whereby more efficient dilutes fish’s burden. Using datasets 57 133 char, linear regression modelling showed age diet indices dominan...

Abstract A fundamental assumption of mark‐recapture studies is that individuals do not lose their marks or tags, because tag loss can lead to biased parameter estimates. Retention 8‐mm full‐duplex and 12‐mm half‐duplex passive integrated transponder (PIT) tags implanted in the abdomen, opercular musculature, dorsal sinus age‐0+ hatchery male brook trout ( Salvelinus fontinalis ) was evaluated l...
