Dietary α-linolenic for juvenile Nile tilapia at cold suboptimal temperature

Nile tilapia, a tropical species, has been considered for aquaculture in subtropical regions, but its nutritional requirements under suboptimal temperatures are unknown. The present study shows that the α-linolenic requirement for this species under 22 °C is slightly higher than in 28 °C. Therefore, we suggest the increase in the α-linolenic levels in the diet for Nile tilapia during the cold seasons.
