Meeting Abstract
Many fisheries in the Northeastern United states are seasonal as cooling temperatures in the fall trigger many species to migrate offshore away from summer fishing grounds. Once established, the seasons of “open fishing” are difficult to change. By understanding the physiology of commercially and recreationally important species managers can make more informed decisions as to seasonal activity of these species. As a case study, we examined a series of performance metrics related to routine activities in a seasonally active species from New England. The overfished tautog (Tautoga onitis) make short migrations to offshore wintering habitats where they undergo winter dormancy. We analyzed muscle performance, feeding kinematics and the escape response at a range of relevant temperatures in order to establish a comprehensive view of how temperature impacts this species and its associated fishery. Based on the research we present here we can provide managers a more accurate picture as to how temperature and future climate warming will impact seasonal distribution and activity. Understanding the seasonality of fish behavior and physiology is integral in a management strategy.
