Within the framework of MAIA, a study was led by the Syndicat Mixte Espaces Littoraux de la Manche (SyMEL) on the management of exploited shellfish in Chausey Archipelago. This study ended in an interim report and then a final report on this subject.

In the archipelago of Chausey, the praire (Venus verrucosa) undergoes fishing pressure by dredging and recreational low water fishing..

The approach developed in this project aimed to better understand the interactions between the state of praire populations in the archipelago and the levels and uses of catches. The multidisciplinary approach aims to bring the local elements of knowledge interaction at work, to propose management rules and shared tools followed.

On the one hand, the work carried out on praire and trophic resource has helped to bring new scientific knowledge on the status of populations across Chausey. Recommendations of scientific monitoring are removed from these 2 years, including vulnerability to fishing pressure at certain sites in the archipelago with low growing performance.

On the other hand, the work carried out on the characterization of fishing practices helped to bring quantitative, qualitative and behavioral elements. Low water fishing pressure across the archipelago can be estimated in terms of space and quantity.

The sampling tool developed (Symel Dredge) and allometric relationships defined in the biological study now allow to estimate exploitable populations in the next years on the sites. This work can be conducted with professional fishermen.partnership.

Annual monitoring can be initiated to test the prediction of resources avalaible for porfesisonnalet leisure low water fishing.
