Abstract

The effects of probiotic Primalac (Lactobacillus acidophilus, Lactobacillus casei, Enterococcus faecium and Bifidobacterium bifidium) was investigated on Reproductive performance of Famale Livebearing and Survival larvae Black Molly (Poecilia sphenops.)Three practical diets containing 0 (control), 0/4, 0/9 and 0/14% Probiotic Primalac were used to feed fish. Fish were fed 4 times per dayThis experiment was performed since spring 2009 for 60-days in center of Fish propagation and culture at Hemat Abad.132 brood stock (36 males and 96 females) were randomly distributed between12 aquariums (30*40*60) were used with water temperature 28±1◦c. In each aquarium Were placed 8 females and 3 males. The volume of each aquarium was 500 L capacity. For covering the larvae, we made home place with nylone.. At the end of 60-days, the fish receiving Probiotic Primalac feeds showed significantly higher number of larvaethan those fed the control diet So that maximum larva were at 1.4gr/Kg diet Primalac (122 individual.) and minimum larva were at diet without Primalac (54 individual)(P<0.05).Maximum of survival famales and males observed at 1.4gr/Kg diet Primalac and minimum of observed at diet without Primalac (control)(P<0.05).The results indicated that Probiotic Primalac could affect survival and Reproductive performance of Famale Livebearing and Survival larvae Black Molly(P<0.05).
