Sumario:Most of the world’s marine fishery resources are overexploited. Despite the measures implemented to reverse this trend, many depleted stocks have failed to recover. Recovery of fish stocks will be dependent on their reproductive potential. However, there is increasing awareness that the traditional indicators of reproductive potential are inadequate, as they do not represent the capacity of populations to annually produce viable eggs and larvae. In addition, egg production is also influenced by environmental conditions; the exact effects of which remain largely unknown. Worldwide, considerable research is underway which examines linkages between fish reproductive success and subsequent population dynamics. The aim of this conference is to better understand the causes and consequences of changes in reproductive potential. To broaden and integrate international advancements by (i) standardization and cross calibration of different protocols, (ii) demonstration of the latest methodological advances and (iii) creation of a common research platform that provides fisheries managers with realistic tools to promote stock recovery. And to explore important advances made recently to improve stock assessment methodology and promote sustainable exploitation of marine fishery resources.
