Title: Multidisciplinary tools for a rational management of fisheries resources

Name: Cláudia Moreira

 

Up-to-date scientific information shows that several fish species are currently exploited beyond their maximum sustainable threshold, leading to situations of over-exploitation and depletion of fish stocks. The spatial delineation of stocks is often based on stationary fish distributions, oceanographic features, and political or administrative boundaries, and often the management areas do not match the biological meaningful entities. Nowadays, the most common tools applied in Fisheries Science, to assess fish stocks, focus on the genetic and phenotypic characterization of the fish populations. These tools focus essentially on the geographic variation and dispersal of individuals, and infer the reproductive isolation or local adaptation, mixing rate and individuals’ movement patterns and rates.
The aim of this study was to apply multidisciplinary tools - molecular analyses, geometric morphometrics and otolith chemical analyses - to study the population structure of an important small pelagic fish harvested in the North-East Atlantic.
