An investigation on the growth and reproductive performance of Poecilia reticulata Peters (Cyprinodontiformes: Cyprinidae) fed diets with dried insects
Abstract :In the study, five feeds given to guppies (Poecilia reticulata) were evaluated for their effects on growth and reproductive performance of females. Feeds namely Diet I, II, III, IV and V formed flake food, blood worm, locust, rhino beetle and flour worm, respectively. Blood worm, locust, rhino beetle, flour worm were insects, and flake food was a commercial fish food. The growth and reproductive performance were investigated based on growth parameters, gonadal development and fry production. Fish fed Diet II, IV and V had a higher specific growth rate compared to the other groups. The ovary weight of guppies fed Diet II was significantly (p<0.05) higher than those with diets I, III, IV and V. The absolute fecundity values were 35.5±0.02, 58.8±0.04, 30.8±0.03, 50.2±0.05 and 48.1±0.02, respectively for the fish fed Diet I, II, III, IV and V. The number of fry produced was also significantly higher in fish fed Diet II. Between the groups, fish fed Diet II obtained the highest mean gonad weight and gonadal somatic index. The results of the present study demonstrated that the use of such dried insects is a reliable source for commercial guppy farming and the reproductive performance of the fish increased
