Efeito do fotoperíodo sobre a composição do filé de juvenis de tilápia do Nilo

Abstract: Com este estudo objetivou-se avaliar o efeito do fotoperíodo sobre a composição centesimal de filés de juvenis de tilápia do Nilo. Utilizou-se um delineamento inteiramente casualizado com cinco tratamentos (0L:24E; 6L:18E; 12L:12E; 18L:6E; 24L:0E) e quatro repetições. Foram utilizados 160 alevinos de tilápia, distribuídos em 20 aquários (20L) em sistema de recirculação, temperatura controlada em 27 ºC e densidade de oito peixes por aquário. Os peixes foram alimentados duas vezes ao dia, com ração comercial ext… Show more

“…In H. malabaricus, 77.71% moisture, 20.7% crude protein, 1.39% ash, and 0.84% lipid were observed. In O. niloticus, the percentage of moisture and ash did not change with different photoperiods, which was also observed for H. intermedius in the present work (Veras et al, 2014). However, also crude protein did not change in H. intermedius because of photoperiod, which is opposite what is observed in the above mentioned species.…”

“…The lipid content is used as a criterion for comparing different species of fish, by which fish are considered fat with a minimal of 10% lipid content, semi-thin from 2.5 to 10% lipid content, and thin with a maximum of 2.5% lipid content (Veras et al, 2014). Thereby, the lipid contents observed in the present study allow us to consider H. intermedius juveniles as a semi-thin product.…”
