No. of bitstreams: 1 Adriano_Vitor_Azevedo.pdf: 597728 bytes, checksum: e6a13262b762314a59f32f1842001ead (MD5) Previous issue date: 2015-09-02 / The objective was proportional an analysis in the processing of Nile tilapia in different weight ranges. A total of 200 tilapias were used, separated into four weight groups: P1 (180 to 220 g); P2 (280-320 g); P3 (380-420 g) and P4 (480-520 g), derived from a farmers association of fish in net-tank from the hydroelectric Governor José Richa-Salto Caxias, Pr. The fish were processed in an industrial environment . For statistical analysis, we used the analysis of variance, followed by F test at 5% significance level, and when significant Tukey test. The found average weights were P1 (206g), P2 (297g); P3 (382g) and P4 (491g). A clean trunk proceeds analysis was significant for P2 weight ranges (51.15%), P3 (51.36%) and P4 (53.01%). Proximate analysis for clean trunks were used, and the weight ranges P3 and P4 were significant for protein and fat. As the production cost and manufacturing proceeds for the clean trunk, the weight range is indicated P2 / O objetivo do trabalho foi o de proporcionar uma análise no processamento da tilápia do Nilo em diferentes faixas de peso. Foram utilizados um total de 200 tilápias, separadas em quatro grupos de pesos: P1 (180 a 220 g); P2 (280 a 320 g); P3 (380 a 420 g) e P4 (480 a 520 g), oriundos de uma associação de aquicultores de peixes em tanques-rede do reservatório da Usina Hidrelétrica Governador José Richa-Salto Caxias, PR. Os peixes foram processados em um ambiente industrial. Para a análise estatística, foi utilizada a análise de variância, seguido do teste F em 5 % de significância, e o teste de Tukey quando significativo. Os pesos médios encontrados foram P1 (206g), P2 (297g); P3 (382g) e P4 (491g). A análise de rendimento de tronco limpo mostrou-se significativa para as faixas de peso P2 (51,15%), P3 (51,36%) e P4 (53,01%). Para análise centesimal foram utilizados os troncos limpos, e as faixas de peso P3 e P4 foram significativas para proteína e gordura. Quanto ao custo de produção e rendimento industrial para obter o tronco limpo, a faixa de peso indicada é o P2
