At the “swim up” stage in the development of larval fish, they need to get to the water surface to inflate their swim bladder. Sometimes the surface tension of the water may be too great and they aren’t able to penetrate it. This paper details a method to improve survival of small larvae by the addition of egg white and camphor grain to the water.

| Abstract: | To prevent surface tension-related deaths in horse mackerel larvae, Trachurus mediterraneus, camphor grain (CG; 26 and 52 mg L-1with and without ethanol) and chicken egg white (EW; 40 and 80 µL L-1) were added to rearing water. Compared with the control groups, supplementation of EW (40–80 µL) and CG (52 mg L-1, dissolved in ethanol) significantly improved the survivals of horse mackerel larvae (P<0.05). At the end of the 10 days after hatching, the survival rates of EW-40 and EW-80 were 64% and 72% respectively. No clear correlation was found between surface tension and survival rate. | ||||||||||||||||
