Resumo: The objective of this work was to determine the effect of photoperiod on the cannibalism, growth, and body composition of giant trahira (Hoplias intermedius) juveniles. A completely randomized design was employed, with four photoperiods - 0L:24D, 6L:18D, 12L:12D, and 18L:6D, hours of light (L): dark (D) - and four replicates, for a period of 90 days. The analyzed parameters were: cannibalism, growth in weight and length, food consumption, feed conversion, protein efficiency rate, muscle growth, and body composition (moisture, lipid, ash, and crude protein). Fish from the 12L:12D photoperiod showed the highest survival rate and no cannibalism, as well as a great uniformity for length and mass values at the end of the experiment. The best photoperiod for giant trahira juveniles is 12L:12D, as these fish showed growth uniformity and no cannibalism, while fish from the 6L:18D and 18L:6D groups had a greater diameter of white muscle fibers and a higher frequency of greater diameter fibers. Giant trahira showed the lowest value for lipids at 6L:18D and the highest value at 12L:12D. Photoperiod affects survival and cannibalism; regarding body composition, only lipids are influenced by photoperiod.

Um delineamento inteiramente casualizado foi empregado, com quatro fotoperíodos - 0L:24D, 6L:18D, 12L:12D e 18L:6D horas de luz (L) por horas de escuridão (D) - e quatro repetições, pelo período de 90 dias. Os parâmetros analisados foram: canibalismo, crescimento em peso e comprimento, consumo alimentar, conversão alimentar, taxa de eficiência proteica, crescimento muscular e composição corporal (umidade, lipídios, cinzas e proteína bruta). Os peixes do fotoperíodo 12L:12D apresentaram maior taxa de sobrevivência e nenhum canibalismo, bem como grande uniformidade nos valores de comprimento e massa ao final do experimento. O melhor fotoperíodo para juvenis de trairão é 12L:12D, uma vez que os peixes mostraram uniformidade de crescimento e nenhum canibalismo, enquanto peixes dos grupos 6L:18D e 18L:6D apresentaram maior diâmetro de fibras musculares brancas e maior frequência de fibras de maior diâmetro. Os peixes apresentaram menor valor de lipídios no fotoperíodo 6L:18D, e o maior valor no 12L:12D. O fotoperíodo afeta a sobrevivência e o canibalismo; quanto à composição corporal, somente os lípidos são influenciados pelo fotoperíodo.Embrapa Secretaria de Pesquisa e Desenvolvimento Pesquisa Agropecuária Brasileira2019-06-03T12:44:31Z2019-06-03T12:44:31Z2018-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfRAMOS, S.
