Abstract Most studies about benthic community use small-scale sampling methods focused on the infauna such as grabs or box-corers. The data collected by scientific trawl surveys in all European waters, frame of Common Fishery Policy Data Collection Multiannual Program, can be used to study impact large-scale fisheries trawling. However, catchability trawls is very dependent nature seabed well r...

Bycatch in demersal trawl fisheries challenges their sustainability despite the implementation of various gear technical regulations. A step towards extended control over catch process can be established through a real-time monitoring tool that will allow fishers to react unwanted compositions. In this study, for first time commercial fishery sector, we introduce an automated description levera...

Media Independent Handover (MIH) is an emerging standard which supports the communication of network-critical events to upper layer mobility protocols. One of the key features of MIH is the event service, which supports predictive network degradation events that are triggered based on link layer metrics. For set route vehicles, the constrained nature of movement enables a degree of network perf...

The Banc d’Arguin in Mauritania is an area characterised by shallow waters and tidal flats with extensive seagrass beds. The aim of this study was to determine the role of the Banc d’Arguin tidal flats as a habitat and a nursery for shrimps. Shrimps were sampled in the Baie d’Aouatif in the intertidal (ponds, Zostera noltii seagrass beds and bare sediment) with a push net during high and low ti...
