Resumo: The aim of this experiment was to study Clarias gariepinus carcass in three weight categories (P1=below 1kg; P2= 1 to 2kg and P3=over 2kg) to analyze yield of carcass with head (YCH), without head (YCW), fillet (YF), abdominal muscles (YAM), eatable parts (YEP), dressed out (YDO) and percentages of skin (PSK), head (PHE), viscera (PVI), total residues (PTR); and to determine the proximate composition of fillet (crude protein, moisture, fat and ash) . Sixty catfish were used in a completely randomized design (3 trataments with 20 replications), with 5% significance level. Fillet yield was higher for P2 (38,61%) than for P1 and for P3 fillet. The eatable parts and dressed out yield were higher for P2 (YEP=46,27% and YDO=56,67%), but were not different from P3. The carcass with head was higher than P3, and didn’t differ from P2. P2 was lower in PSK (4,64%), PHE (23,62%) and PTR (53,73%), without being different from P3 in percentages of head and total residues. There was no significant difference for yield of abdominal muscles, carcass with head, percentages of viscera. P2 (2,25% and 77,49%) did not differ from P1 (1,51% and 77,78%) and from P3 (3,03% and 76,39%) for fat and moisture, respectively, while for crude protein there was no significant difference (P > 0.01). It may be concluded that P2 provided better filleting yieds, while the proximate composition of fillet in the three weight categories was relatively similar to the increase of fat deposition in the fish over 1kg live weight.

Foram utilizados 60 bagres, em delineamento inteiramente casualizado, 3 tratamentos com 20 repetições, em nível de significância de 5%. O rendimento de filé foi maior para P2 (38,61%) que para P1 e P3. O rendimento das partes comestíveis e tronco limpo foram superiores para P2 (RPC=46,27% e RTL=56,67%), mas sem diferirem do P3. O rendimento de carcaça sem cabeça foi maior para P3, não diferindo de P2. O P2 foi inferior para PPE (4,64%), PCA (23,62%) e PRE (53,73%), sem diferir de P3, para porcentagem de cabeça e de resíduos totais. Não houve diferença significativa para rendimentos dos músculos abdominais, carcaça com cabeça e vísceras. P2 (2,25% e 77,49%) não diferiu do P1 (1,51% e 77,78%) e P3 (3,03% e 76,39%), para gordura e umidade, respectivamente, enquanto, para proteína bruta, não houve diferença significativa. Conclui-se que P2 apresentou melhores rendimentos de filetagem, ao passo que a composição proximal do filé, nas três categorias de peso, foi relativamente similar, com aumento de deposição de gordura nos peixes acima de 1kg de peso vivo.Editora da Universidade Estadual de Maringá2008-07-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/432410.4025/actascianimsci.v21i0.4324Acta Scientiarum.
