Abstract

Discards are common in commercial fishery, and are evaluated in order to support fisheries management in the region. Fish discards in the middle Solimões River were described through daily monitoring of fishing activities by the commercial fleet of the town of Tefé. By making use of analyses of correlation and covariance, determinant factors for discards in three different types of fisheries were evaluated. The crew selected the fish at the moment of capture, by species and size. Among the most discarded fish species were silver prochilodus, peacock bass, and curimata inormata; however, the most frequently discarded were Siluriform species. The fishing gear analyzed featured differences in their discarding characteristics. Discard was lower during the flood period (5-17% of catches, depending on gear) than during the dry season (20-62% of catches, depending on gear)
