Abstract Size-selective harvesting is expected to reduce the average age and weight of commercially exploited fishes. The loss larger, older fish has been hypothesized negatively affect metrics population viability, such as spawning behaviour, recruitment, adult survival. Most studies date have focussed on individual stocks. Here, we examine trends in at broad taxonomic temporal scales, using subsets data compiled 95 marine Following moderate declines between 1960 1990, find that generally...
Marine fisheries have a long history of exploitation, with the potential to shape many life traits, particularly those that are heritable, such as age and size at maturity. Here, we analyze 43 marine fish stocks, using prewhitened cross-correlations, examine relationship between past levels fishing mortality ( F) resulting shifts in structure. Significant cross-correlations F structure were evident 88% stocks examined. For 37% changes followed F, whereas 39% cases preceded F. Sensitivity...
