Pesquisa do Estado do Amazonas Instituto Federal do Amazonas (IFAM) - Campus Presidente Figueiredo The tambaqui Colossoma macropomum is the main native species in fish farming in Brazil, with an estimated annual production of 278,671 tons in 2020. Several technological factors are needed to leverage the production of native fish, including the supply of juveniles with genetic quality, good zootechnical performance, in addition to an affordable price. Therefore, producing feed management protocols for breeders from genetic improvement are necessary. The present study evaluated the impact of diet on the reproductive success of tambaqui, aiming to implement management protocols for juvenile production stations in the Amazon. One hundred fish from the AquaBrasil program, aged 5 years, were used. Four tanks of 600m2 T1- daily feed with 28% of crude protein (CP) were used; T2 ??? daily feeding with 32% CP; T3 ??? feeding 3 times a week with 28% CP and T4 ??? feeding 3 times a week with 32% CP, in which 25 fish per tank (15 males and 10 females) were stocked. The sampling unit was the induced female, identified with a pittag microchip. Reproductive indices were compared using descriptive statistics and measures of central tendency. Statistical analyzes were performed using the statistical program R. ANOVA and ANCOVA tests were applied, at a 5% confidence level, to identify significant differences between treatments. The variables, hatching rate and survival rate did not present the necessary assumptions of homogeneity of variance to perform the statistical analyses, being then submitted to descriptive analysis of the data obtained. There was no significant difference between treatments. The animals showed satisfactory results for the species in all treatments evaluated, demonstrating that even in the absence of statistical differentiation, the performance of the animals did not suffer any loss. Based on the evaluated data, it is possible to assume that fish farming stations that work with tambaqui breeding can adopt a fish feeding regime with 28% crude protein, being administered three times a week, without harming the quality performance of the breeders of oocytes and larvae. O tambaqui Colossoma macropomum ?? a principal esp??cie nativa nos cultivos de peixes no Brasil, com uma produ????o anual estimada de 278.671 toneladas no ano de 2020. Diversos fatores tecnol??gicos s??o necess??rios para alavancar a produ????o de peixes nativos, entre a oferta de juvenis com qualidade gen??tica, bom desempenho zoot??cnico, al??m de pre??o acess??vel. Sendo assim, produzir protocolos de manejo alimentar para reprodutores oriundos de melhoramento gen??tico se fazem necess??rios. O presente estudo avaliou o impacto do regime alimentar no sucesso reprodutivo de tambaqui, visando a implanta????o de protocolos de gest??o de esta????es de produ????o de juvenis na Amaz??nia. Foram utilizados 100 peixes oriundos do programa AquaBrasil, com idade de 5 anos. Foram usados quatro tanques de 600m2 T1- alimenta????o di??ria com 28% de prote??na bruta (PB); T2 ??? alimenta????o a di??ria com 32% de PB; T3 ??? alimenta????o 3 vezes na semana com 28% PB e T4 ??? alimenta????o 3 vezes na semana com 32% PB, nos quais foram estocados 25 peixes por tanque (15 machos e 10 f??meas). A unidade amostral foi a f??mea induzida, identificada com microchip pittag. Os ??ndices reprodutivos foram comparados por estat??stica descritiva e medidas de tend??ncia central. An??lises estat??sticas foram realizadas no programa estat??stico R. Foram aplicados os testes ANOVA e ANCOVA, ao n??vel de 5% de confian??a, para identifica????o das diferen??as significativas entre os tratamentos. As vari??veis, taxa de eclos??o e taxa de sobreviv??ncia n??o apresentaram os pressupostos de homogeneidade de vari??ncia necess??rios para execu????o das an??lises estat??sticas, sendo ent??o submetidas a an??lises descritivas dos dados obtidos. N??o houve diferen??a significativa entre os tratamentos avaliados. Os animais apresentaram resultados satisfat??rios para a esp??cie em todos os tratamentos avaliados, demostrando que mesmo perante a aus??ncia de diferencia????o estat??stica, o desempenho dos animais n??o sofreu nenhum dem??rito. Com base nos dados avaliados, ?? poss??vel assumir que as esta????es de piscicultura que atuam com reprodu????o de tambaqui podem adotar um regime de alimenta????o de peixes com 28% de prote??na bruta, sendo administrada tr??s vezes por semana, sem prejudicar o desempenho dos reprodutores na qualidade dos ov??citos e larvas.
