| Popis: | Tilapias are produced worldwide, including subtropical areas. In turn, dietary fatty acids can enhance resistance under cold stress. The present study reports the nutritional effect on suboptimal temperature tolerance based on histopathological alterations in tilapia (Oreochromis niloticus). Fish (initial weight: 34.02 ± 0.79) were exposed to two different temperatures (20 °C and 30 °C) for 30 days. Under both conditions, fish were fed two different diets based on the linoleic/α-linolenic ratio (n6/n3 = 12.02 and n6/n3 = 3.85). The most important alterations in liver caused by temperature included high cellular hyperplasia in fish at 30 °C (P |
