Avoidance of fisheries-induced evolution: management implications for catch selectivity and limit reference points
I examined how the fitness (r) associated with early- and late-maturing genotypes varies with fishing mortality (F) and age-/size-specific probability of capture. Life-history data on Newfoundland's northern Atlantic cod (Gadus morhua) allowed for the estimation of r for individuals maturing at 4 and 7 year in the absence of fishing. Catch selectivity data associated with four types of fishing ...

متن کاملCan catch shares prevent fisheries collapse?
Recent reports suggest that most of the world's commercial fisheries could collapse within decades. Although poor fisheries governance is often implicated, evaluation of solutions remains rare. Bioeconomic theory and case studies suggest that rights-based catch shares can provide individual incentives for sustainable harvest that is less prone to collapse. To test whether catch-share fishery re...
متن کاملEstimating Ideal Points from Votes and Text
We introduce a framework for combining vote data and text data within a single formal and statistical framework. Formally, we model vote choice and word choice in terms of a common set of underlying preference parameters. Statistically, we implement a method for recovering these preference and location parameters. The method estimates the number of underlying ideological dimensions, models zero...
متن کاملInfluence of Skipped Spawning and Misspecified Reproductive Schedules on Biological Reference Points in Sustainable Fisheries
—During the spawning season, adult striped bass Morone saxatilis can occur outside known spawning tributaries. This phenomenon has been observed in other fishes, suggesting that investigators have misspecified reproductive schedules by assuming annual spawning. Across a range of species, skipped (i.e., nonannual) spawning is positively correlated with longevity. Therefore, reproductive schedule...
