Abstract: 

This project delineates an integrated study of meagre Argyrosomus regius ecology in Portugal, with emphasis on the movements to and from estuarine areas considered important spawning and nursery grounds for the species across its distribution range. The meagre forms ephemeral spawning aggregations that result in dedicated fishing effort and high risks of overexploitation. These risks together with the paucity of current data and difficulties in applying analytical stock assessment models underscore an urgency to search for innovative alternatives that can inform management and safeguard the reproductive resilience. This project uses an interdisciplinary approach of five techniques including natural markers, artificial tags and bioacoustics. The integrated analysis of results will provide timely answers for the science of fish migration and useful advice for the sustainability of fisheries.
