Abstract

This research evaluated the nonspecific immune responseand growth of Litopenaeus vannamei fednucleotide diet.  In Laboratory, juveniles were reared in two groups of glass aquaria, each with threereplications.  Shrimps in group one were fed nucleotide diet and in group two were fedpellet four consecutiveweeks. Total Haemocyte Count and Phenoleoxydase activity were evaluated at the end of feeding whilegrowth was measured at two weeks interval. At the end of feeding, shrimps were intramuscularlyinjectedwith Vibrio harveyi  0.1x106 cfu.shrimp-1.  In tambak, juveniles were raised in two groups of net cages(hapa), each with three replications. One group was fed nucleotide diet while the other wasfed pellet forfour weeks. Total Haemocyte Count of shrimp fed nucleotide diet significantly increased up to 87% higherthan shrimps fed pellet.  Phenoleoxydase activity of shrimp fed nucleotides diet also increased isignificantlyas compared to shrimp fed pellet (p=0.02). Higher resistance and growth were observed in shrimp fednucleotide diet. In tambak, weight gain of shrimp fed nucleotide was 35.75% greater than shrimp fedpellet. Survival rate (83.24%) was higher than shrimp fed pellet (81.71%).  As conclusion, oral administrationof nucleotide at 400 mg.kg-1 diet could enhancethe nonspecific immune response, resistance, and growth ofL. vannamei.

Abstract

A study was carried out to evaluate the efficacy of Baker’s yeast (Saccharomyces cereviciae) to enhancenonspecific immune response and growth of Nile tilapia fish (Oreochromis niloticus). The fish were obtainedfrom Freshwater Hatchery Tateli (BP3I), Marine and Fisheries Office, North Sulawesi. After acclimatizationfor two weeks in 1000 L fiberglass tank, fish with an average weight of 9 g were put in five 45 L-aquaria ata density of 15 fish/aquarium. During the experiment, fish were fed with feed pellet supplemented withfive different doses of baker’s yeast (10, 20, 30, 40 g yeast/kg pellet) for four consecutive weeks at 5% bw/day, twice a day. Fish in different aquarium received different dose of baker’s yeast. Immune parametersincluding total leucocyte count and phagocytosis activity and growth of fish were measured at two weeksinterval. After four weeks of feeding, total leucocyte count and phagocytosis activity of phagocyte cells offish fed pellet supplemented with 10 g yeast/kg pellet increased significantly as compared to that ofcontrol fish (p<0.01). Growth of fish fed pellet supplemented with 10 g yeast/kg pellet also increasesignificantly as compared to control group (p=0.01). Average weight gain of fish fed pellet supplementedwith 10 g yeast/kg pellet was 15.00±1.00 g while control fish was 8.33 g. As conclusion, supplementationof baker’s yeast in feed could enhance nonspecific immune response and growth of Nile tilapia fish.
