Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 12
Abstract
This paper evaluated usage possibility of white worm, Enchytraeus albidus added to brown trout fry pellets at different percentages. The experiment was designed as 4 groups (Live feed, pellet, and additions of (0.25 and 0.5%) white worm with 3 replicates. Each tank included 30 fish. Weigh gains and survival rates of fish were compared and assumptions were made with respect to consumption. It was found that addition of white worm to diets increased weight gain slightly (p>0.05). No differences were observed at survivals of fish (p>0.05). Feed conversion ratio was the higher in Lf group and followed by 0.5, 0.25 % white worm added groups and pellet groups in order. It may be suggested to fish farmers adding White worm at small quantities may provide better survival with not significant changes in total production.
