Bycatch of the Isla del Rosario (Gulf of Salamanca, Colombian Caribbean) artisanal shrimp fishery in an approximation to the biodiversity impact

ABSTRACT In the period March 2009-February 2010 the fish bycatch of the artisanal shrimp fishery operating off the beach of Isla del Rosario (Gulf of Salamanca, Colombian Caribbean) was evaluated and length-frequency data analysis were done for five of the main ichthyic species. For this purpose, da...
