Resumo: | The present research had as objectives to evaluate the productive performance during the initial phase and growing and the fillet yield obtained in the fatten phase of different strains of Nile tilapia existents in Brazil. The studied strains were: the intraspecific hybrid (HIB), resulting from crossing between the male Chitralada (Thailand), and the female Bouaké (Brazilian); the Bouaké (BOK) popularly known like Nile tilapia; the Chitralada, first Thailand generation (CHI1); the Chitralada, second Thailand generation (CHI2). This experiment was carried out in the period from December 2000 to August 2001 and had four phases as characteristic. To the three first phases was used an installation type greenhouse, with 24 boxes, with capacity to 250L, where were tested the four treatments, with six replicates. To the fourth phase, the fishes were individually marked and put in a land tank with 300m². The obtained results to the final weight for the growing phase (3a phase) were: 93,66g (HIB); 71,79g (BOK); 108,17g (CHI1) e 114,31g (CHI2), and for apparent feed conversion ratio 1,77 (HIB); 1,98 (BOK); 1,46 (CHI1) e 1,45 (CHI2) and for weight gain there was the increasing from 47% to 49% (CHI1 and CHI2, respectively) and 17% (HIB) in relation to BOK. The CHI1 and CHI2 and the HIB showed a mayor tolerance and a mayor storage density and final biomass than the BOK. To the average values of carcass weight in the fatten phase (4ª phase) were: 261,99g (HIB); 177,98g (BOK); 292,75g (CHI1) e 307,82g (CHI2); the strains CHI1, CHI2 and the HIB presented the best results, obtaining significative differences of BOK. The results obtained to fillet yield showed that there was no significative difference between the strains. These results showed, that the strains with best general performance, was Chitralada (CHI1 and CHI2), followed by hybrid (HIB) and the Bouaké (BOK) strains. |

As linhagens estudadas foram: o híbrido intra-específico (HIB), cruzamento entre o macho Chitralada (tailandês) e a fêmea Bouaké (brasileira); a Bouaké (BOK), conhecida popularmente como Nilótica; a Chitralada, primeira geração da tailandesa (CHI1); a Chitralada, segunda geração da tailandesa (CHI2). Este experimento foi conduzido em quatro fases, no período de dezembro de 2000 a agosto de 2001. Durante as três primeiras fases foi utilizada uma instalação do tipo estufa, com 24 caixas, com capacidade de 250L, nas quais foram testados os quatro tratamentos com seis repetições. Na quarta fase, os peixes foram marcados individualmente e colocados dentro de um mesmo viveiro de terra de 300m². Para a fase de crescimento (terceira fase), os valores médios de peso final obtidos foram 93,66g (HIB); 71,79g (BOK); 108,17g (CHI1) e 114,31g (CHI2), de conversão alimentar aparente 1,77 (HIB); 1,98 (BOK); 1,46 (CHI1) e 1,45 (CHI2); para ganho de peso houve um aumento de 47% a 49% (CHI1 e CHI2, respectivamente) e 17% (HIB) em relação a Bouaké. A linhagem Chitralada (1ª e 2ª geração) e o híbrido mostraram maior tolerância a maior densidade de estocagem e biomassa final do que a linhagem Bouaké. Os valores médios de peso de carcaça obtidos na fase de engorda (quarta fase) foram: 261,99g (HIB); 177,98g (BOK); 292,75g (CHI1) e 307,82g (CHI2); sendo as diferenças significativas entre a Chitralada e o híbrido da Bouaké; para o rendimento de filé não houve diferença significativa. Estes resultados demonstraram que a linhagem de melhor desempenho foi a Chitralada (CHI1 e CHI2), seguida da linhagem híbrida (HIB) e da linhagem Bouaké (BOK).Editora da Universidade Estadual de Maringá2008-04-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/186410.4025/actascianimsci.v26i2.1864Acta Scientiarum.

The studied strains were: the intraspecific hybrid (HIB), resulting from crossing between the male Chitralada (Thailand), and the female Bouaké (Brazilian); the Bouaké (BOK) popularly known like Nile tilapia; the Chitralada, first Thailand generation (CHI1); the Chitralada, second Thailand generation (CHI2). This experiment was carried out in the period from December 2000 to August 2001 and had four phases as characteristic. To the three first phases was used an installation type greenhouse, with 24 boxes, with capacity to 250L, where were tested the four treatments, with six replicates. To the fourth phase, the fishes were individually marked and put in a land tank with 300m². The obtained results to the final weight for the growing phase (3a phase) were: 93,66g (HIB); 71,79g (BOK); 108,17g (CHI1) e 114,31g (CHI2), and for apparent feed conversion ratio 1,77 (HIB); 1,98 (BOK); 1,46 (CHI1) e 1,45 (CHI2) and for weight gain there was the increasing from 47% to 49% (CHI1 and CHI2, respectively) and 17% (HIB) in relation to BOK. The CHI1 and CHI2 and the HIB showed a mayor tolerance and a mayor storage density and final biomass than the BOK. To the average values of carcass weight in the fatten phase (4ª phase) were: 261,99g (HIB); 177,98g (BOK); 292,75g (CHI1) e 307,82g (CHI2); the strains CHI1, CHI2 and the HIB presented the best results, obtaining significative differences of BOK. The results obtained to fillet yield showed that there was no significative difference between the strains. These results showed, that the strains with best general performance, was Chitralada (CHI1 and CHI2), followed by hybrid (HIB) and the Bouaké (BOK) strains. |
