We contrast catchability of walleye (Sander vitreus) and northern pike (Esox lucius) populations with angling fisheries across regions that differ twofold in growing-degree-days and productivity and sixfold in fish diversity. Populations of both species in Alberta, Wisconsin, Minnesota, and Oneida Lake, New York, had density-dependent catchability with approximately tenfold higher catchability in Alberta than in the other regions when density was controlled for. There is no evidence that the higher catchability estimates for Alberta walleye and northern pike are due to differential spatial distributions, enhanced hook avoidance due to catch and release or to differential size structure of the populations, or to differences in harvest regulations. We argue that the most likely explanation for the tenfold higher catchability is increased hunger resulting in enhanced foraging activity in the region with a substantially shorter growing season, lower prey productivity, and lower prey community diversity. Regardless of the proximate causes, higher catchability of fish harvested in recreational fisheries in Alberta substantially increases their vulnerability to overharvest and collapse if angling effort is unabated.Résumé : Nous comparons la capturabilité de populations de doré jaune (Sander vitreus) et de grand brochet (Esox lucius) dans la pêche sportive dans diverses régions présentant des différences du simple au double du nombre de degrés-jour de croissance et de la productivité, et du simple au sextuple en ce qui concerne la diversité des poissons. Des populations des deux espèces en Alberta, au Wisconsin, au Minnesota et dans le lac Oneida (New York) présentaient des capturabilités dépendantes de la densité, celle de l'Alberta étant environ dix fois supérieure à celles des autres régions quand la densité était prise en considération. Aucune observation ne porte à croire que les estimations de capturabilité plus élevées pour les dorés jaunes et les grands brochets en Alberta découlent de répartitions différentielles, d'un plus grand évitement des hameçons en raison de la pêche avec remise à l'eau, de différences sur le plan de la structure de tailles des populations ou de différences touchant à la réglementation des prises. Nous postulons que l'explication la plus vraisemblable pour la capturabilité dix fois plus élevée en Alberta est la faim plus intense se traduisant par une activité de quête de nourriture accrue dans cette région caractérisée par une période de croissance sensiblement moins longue, la productivité plus faible des proies et la plus faible diversité des communautés de proies. Quelles qu'en soient les causes immédiates, à défaut d'une réduction de l'effort de pêche sportive, la plus grande capturabilité des poissons visés par cette pêche en Alberta accroît considérablement leur vulnérabilité à la surexploitation et à l'effondrement.

“…The study site was protected from any other forms of fishing and was confined to a short period of intensive sampling within one season. Therefore, variations in CPUE were likely not associated with large changes in population density, which would otherwise confine the analyses of abiotic and fishingrelated variations in catch rates (Hansen et al, 2005;VanDeValk et al, 2005).…”

Influence of Population Density and Length Structure on Angler Catch Rate in Kokanee Fisheries

Management agencies are often charged with providing fisheries that lead to angler participation. Catch rate is one of the primary drivers of angler participation but can be influenced by a suite of factors, including population structure (e.g., density and size structure). The complexity of understanding how population structure influences angler catch rate is typified in kokanee Oncorhynchus nerka fisheries. Previous research suggests that angler catch rates of kokanee are positively influenced by fish density and total length. However, that research was based on data collected using size‐selective midwater trawls. Due to the potential limitation of previous research, we sought to (1) understand the relative bias of midwater trawls and gill nets for describing the size structure of kokanee available to anglers and (2) re‐evaluate the influence of fish density and fish length on angler catch rates in kokanee fisheries. Midwater trawl, gill‐net, and creel data were collected on five prominent kokanee fisheries throughout Idaho in 2016 and 2017. Catch composition and percent overlap of midwater trawls, gill nets, and angler‐caught fish were compared to understand the efficacy of midwater trawls and gill nets for representing the size structure of kokanee available to anglers. In addition, the influence of kokanee density and length on angler catch rates was evaluated. Midwater trawls primarily sampled small kokanee (<330 mm) and exhibited little overlap with angler‐caught fish, whereas gill nets sampled more large fish (>330 mm) and exhibited higher overlap with angler‐caught fish when compared to midwater trawls. Fish length was not positively associated with angler catch rates. However, fish density exhibited a positive relationship with angler catch rates. Our results highlight the importance of gear choice for understanding how kokanee populations function and elucidate the tradeoffs associated with population density, fish length, and resulting kokanee fisheries.
