description | Bycatch assessments in trawl fisheries have been mainly referred to an annual scale, ignoring possible seasonal variations. In the Gulf of Salamanca, an artisanal shrimp trawl fleet operates recently and this study evaluates its bycatch for first time, considering the climatic and oceanographic seasonality that dominates the region (runoff and upwelling). 90 hauls in the calm or rainy season (November 2010) and 86 in the windy season (April 2011) were sampled on board of fishing boats. The bycatch to shrimp ratio was 2,69 (2,37 -3,21, 95 % CI) and 6,37 (5,10 – 8,24, 95 % CI) for the calm season and windy season respectively. We recorded a total of 101 taxa, with a large number of juveniles. The community structure of bycatch differed between seasons (ANOSIM, p |
