Plastic pollution has increased worldwide and specially in the oceans, where it turns out to be a concerning threat regarding marine wildlife. Previous research has reported plastic ingestion in the small spotted catshark (Scyliorhinus canicula) as a common occurrence, probably due to its benthic nature and feeding behaviour. S. canicula is one of...

Viral nervous necrosis (VNN) is the most important viral disease affecting farmed fish in the Mediterranean. VNN can affect multiple fish species in all production phases (broodstock, hatchery, nursery and ongrowing) and sizes, but it is especially severe in larvae and juvenile stages, where can it cause up to 100% mortalities. European sea bass ha...

Microfibres are among the most prevalent type of microplastics in marine environments. Man-made fibres derived from cellulose are distributed worldwide, but are often confused with synthetic plastic fibres and consequently neglected. All these fibres may adversely affect aquatic organisms, but their levels and potential effects in wild fish remain...
Article
Marine litter is one of the most concerning threats for marine wildlife especially regarding plastics and their micro-sized forms, widely known as microplastics. The present study evaluates mesoscale spatial (230 km, Catalan coast) and temporal (2007 vs 2017–2018, Barcelona area) differences on the ingestion of anthropogenic fibers in the deep-sea...
