Abstract
The present study aimed to investigate the effect of different soluble biodiesel fraction (SBF) concentrations from burnt soy oil on the embryonic development of curimba (Prochilodus lineatus). The embryos were obtained from semi-natural spawning, collected and transferred to an experimental nursery, in duplicate, under constant aeration, containing different SBF concentrations: treatment I (control), treatment II (0.0645 g.L-1), treatment III (0.129 g.L-1), treatment IV (0.645 g.L-1), treatment V (1.29 g.L-1) and treatment VI (6.45 g.L-1). Mean water quality variables were temperature 23.0 ± 0.1°C, dissolved oxygen 4.58 ± 0.34 mg/L and pH 7.3 ± 0.1. Fish fertilization rates ranged from 50.88 to 81.61%, undergoing alterations beginning at treatment IV (p<0.05). From the tenth hour post-fertilization, delays in embryonic development were observed in relation to the control treatment. Hatching rates ranged from 7.56 to 46.26%, with all groups statistically differing from group I (controls). It is concluded that the different soluble biodiesel fractions interfere in curimba (Prochilodus lineatus) embryonic development.
