- CARACTERIZAÇÃO DA PESCARIA DE GALEOTA-MENOR (Ammodytes tobianus Linnaeus, 1758) NA RIA DE AVEIRO, PORTUGALPublication . Maia; Francisco; Instituto Português do Mar e da Atmosfera, I.P.In the Spring and Summer of 2002 an experimental fishing study was carried out in Ria de Aveiro to determine the impact of the fishing gear, “Rede-da-Galeota”, on its target species the small sandeel Ammodytes tobianus. Catch data showed that this fishing net has the potential to affect both target and non-target species, with negative consequences for the local marine ecosystems. Survey data analysis revealed that the “Rede-da- Galeota” retained 9 by-catch species, 7 of which with commercial interest, namely the sardine (Sardina pilchardus), the thinlip grey mullet (Liza ramada), the thicklip grey mullet (Chelon labrosus), the golden grey rangon) and the european green crab (Carcinus maenas) . The by-catch species made up to 15% of the total catch and the remaining 85% were composed mainly of juvenile specimens of A. tobianus (71,3%). All the commercial bycatch specimens caught by “Rede-da-Galeota” were smaller than the minimum allowed landing sizes. Taking into consideration the poor size selective properties of this fishing net, it is recommended to maintain the “Rededa- Galeota” in the list of prohibited fishing gears and practices in Ria de Aveiro, in compliance with the administrative rule Portaria n.º 563/90 of July 19th.
