Study of probiotics of yeast and lactic acid bacteria in feeding on culture of larvae shrimp (Penaeus monodon)

Abstract

Aceh is one of province which have a high potential of tiger shrimp hatcheries and is one of the main commodities of marine and fishery resources. Actually, tiger shrimp hatcheries in Aceh have been able to supply the demands of the commercial shrimp farms, but prevalence of diseases and the low quality of the postlarvae have resulted in huge damage to both the hatchery and grow-out sector. Hence, the application probiotics of yeast and lactic acid bacteria (YELAB) from fruit in feeding on shrimp culture have a victorious future to inhibit the growth of pathogenic bacteria. The aims of this study are to examine the effect of probiotics YELAB fruit concentration on the growth, survival, feeding convertion ratio (FCR), development of villy cell in intestine organ and water quality of culture reared larvae of tiger shrimp P. monodon. This research will be conducted at Brackish Water Aquaculture Center, Ujong Batee, Aceh Besar district. The concentration of YELAB wiil be arranged for four treatment which are 0 ppm (control), 50 ppm, 100 ppm, and 150 ppm. The analysis parameters are growth, total length, specific growth rate (SGR), feeding conversion rate (FCR), survival rate (SR), amount of villy cell in intestine, water quality and hystology. The significant effect of YELAB on each parameter will be analysed by ANOVA (analysis of varians) with post hoc Duncan comparison of mean scores using SAS software (SAS Inc. Chicago, IL).
