Seasonal variation in fish bycatch associated with an artisanal flounder fishery on Coquimbo Bay, Chile

Seasonal bycatch composition of the flounder gillnet fishery in the Coquimbo Bay, between October 2006 and November 2007 was analyzed. Landed species were identified and weighted (kg). These data set was used to estimate the relative importance of weight and frequency of occurrence of each species i...
