Bromatologia, morfometria e rendimento corporal de Crenicichla punctata: alternativa para sustentabilidade da pesca incidental

Natural resources are being depleted and fish from occasional fishing are discarded due to lack of economic importance. Current paper analyzes fillet yield and the physical and chemical characteristics of the native species Crenicichla punctata, with great hauls, in the tropical and subtropical cis-Andes regions of South America, rivers Orinoco and Trinidad, in the northern basin of the River Parana, in the South, so that it may be included in human diet or preserved in several niches of the consumer market. Samples were captured at 33°16’41.94”S and 52°54’16.67”W, with mail nets, knot space 45mm, where (Crenicichla punctata) is more frequent, although capture aimed at more important fish such as the traira (Hoplias malabaricus) and the jundia (Rhamdia quelen). Fillet yield was higher than 53%, with relevant physical and chemical characteristics. Fillet is thin and has high protein rates. Results show that the species is a low-cost protein source and an alternative for fishing sustainability.
