Abstract: (560 Views) |
Since aquaculture is directly related to human food and water resources, we need to use new techniques to realize sustainable aquaculture. One proposed solution to achieve sustainable aquaculture is to increase the density and improve the diet of farmed fish. The present study investigates the effect of coenzyme Q10 (CoQ10) in the diet on the growth, carcass composition, and ammonia stress of rainbow trout Juveniles. To this end, fish were fed diets containing zero, 0.1, 0.5, and 1% CoQ10 levels for two months. At the end of the breeding period, growth and hematology indicators were calculated, and the carcass composition was analyzed. Ammonia stress was induced at a concentration of 0.6 mg/liter at the end of the study. The findings reveal that adding 1% CoQ10 to the diet before stress leads to increased growth, reduced carcass fat, and increased white blood cell count (p<0.05). Additionally, after ammonia stress, CoQ10 creates resistance in fish, resulting in significantly reduced losses (p<0.05). In general, it can be concluded that CoQ10 can be effectively used in aquaculture to increase growth and improve the ability to tolerate stressful conditions, particularly those caused by an increase in ammonia levels. Furthermore, CoQ10 can be utilized during dense and ultra-dense breeding to enhance growth and increase tolerance to stressful conditions, such as an increase in ammonia levels. As a result, CoQ10 can be used in breeding farms to significantly reduce losses by preventing damage to blood cells and maintaining the oxygenation process.
