Effect of Growth Performance and Survival Rate of Goldfish ( Carassius auratus L. 1758) Fed Garlic ( Allium sativum L.) Supplemented Diets

This research evaluated the effect of different garlic ( Allium sativum ) levels on the nutritional characteristics, growth, and survival rate of goldfish ( Carassius auratus ). Five different commercial experimental diets were prepared garlic was added at levels of 0 (Control), 5, 10, 15, and 20 g<middle dot>kg(-1) . The experiment was carried out for 84 days. Diet 4 group, in which 20 g<middle dot>kg(-1) garlic was added to the trial feed, showed the best growth performance compared to Diet 0 (Control) and other groups (Diet 1, Diet 2, Diet 3) ( p<0.05 ). The best growth in parameters such as body weight gain, percent live weight increase, and specific growth rate was in the Diet 4 group ( p<0.05 ). It was determined that the statistical difference between the groups for the condition factor and survival rate parameters was insignificant. The highest feed conversion rate was determined in the Diet 0 group with the lowest Diet 4 group ( p<0.05 ). As a result, it has been determined that feeding goldfish with the addition of garlic up to 20 g<middle dot>kg(-1) (2%) in its diet will have a positive effect on growth.
