Angler demographics and motivations are an important consideration to successful fisheries management. We examined 29 years of angler license and activity records from the recreational Atlantic salmon fishery in Newfoundland and Labrador, Canada to: (1) provide a contemporary evaluation of angler demographic trends; (2) evaluate age and regional differences between anglers who prioritized retention versus catch‐and‐release; an...

Despite studies on the effect of catch‐and‐release on the survival of Atlantic salmon ( Salmo salar ) being widespread in the literature, studies to date have failed to evaluate the potential role of thermal history. Herein, we show that despite cooler conditions post‐release, 4/18 (22%) salmon died when caught‐and‐released at water temperatures ≥20°C, whereas 1/13 (8%) salmon caught‐and‐released at water temperatures ≤20°C, b...

To evaluate the scientific basis for catch and release as a management tool, a comprehensive 3‐year study compared long‐term survival of Atlantic salmon that were either angled, radio‐tagged and released, or trapped, radio‐tagged and released (control). Overall, the mean survival probability of angled salmon relative to the control group was between 0.94 and 0.98. At cool to moderate water temperatures (10–18°C) mean survival...

The genetic underpinnings of incipient speciation, including the genomic mechanisms which contribute to morphological and ecological differentiation and reproductive isolation, remain poorly understood. The repeated evolution of consistently, phenotypically distinct morphs of Arctic Charr ( Salvelinus alpinus ) within the Quaternary period offer an ideal model to study the repeatability of evolution at the genomic level. Sympa...

Dendritic metapopulations have been attributed unique properties by in silico studies, including an elevated genetic diversity relative to a panmictic population of equal total size. These predictions have not been rigorously tested in nature, nor has there been full consideration of the interacting effects among contemporary landscape features, colonization history and life history traits of the target species. We tested for...
