Abstract

Aeromonas salmonicida are specific bacteria that can cause infections and death to the cultivation of carp (Cyprinus carpio) during larval stage. Death in carp can be prevented by a vaccine, but the vaccine can only be given on the seed over the age of 3 weeks. Maternal vaccination needs to be done to improve the immune system of the larvae by means of inactivated whole cell vaccine A. salmonicida on broodstock ready to spawn. Aims to determine the effectiveness of vaccines on breeders carp to the parent antibody titer test and larvae, as well Survival Rate (SR) and the Relative Percent Survival (RPS) larvae. This research was conducted with a completely randomized design, 4 treatments A (control); B (0.3 ml/kg); C (0.4 ml/kg); D (0.5 ml/kg) and 3 repetitions. The results show that the antibody titer of 0.3 ml dose capable of providing agglutination reaction to pitting 7th (64x dilution) in broodstock, and vaccine doses 0,4ml on broodstock able to give agglutination reaction to the larvae until all 6 wells (32x dilution). A dose of 0.4 ml/kg resulted the highest SR and RPS with 96.11% and 81.25% respectively. Clinical symptoms of redness in control larvae was spread throughout the body whereas on the vaccine treatment was only in certain body parts.Keywords: A. salmonicida, vaccines, maternal immunity, larva, specific immune respon

Abstract

Water temperature has an influence on the development and growth of fish larvae. The appropriate water temperature can caused the development and growth of fish larvae optimum. This research aimed to study the effect of water temperature on the development and growth of brown marbled grouper larvae. This experimental design used a completely randomized design that had 3 treatments (26-28°C, 28-30°C, 30-32°C) equipped with 3 replications each. The parameters observed were the duration of yolk absorption, morphogenesis of larvae, and growth of body length. Data of larval morphogenesis development were analyzed descriptively, while the duration of yolk absorption and larval growth were analyzed of variance and post hoc test using the Least Significant Difference (LSD). The results showed that water temperature influenced morphogenesis development, the duration of yolk absorption, and the growth of larval significantly different. The result showed, larvae had morphological development and duration of yolk absorption faster in warmer incubation media.

Abstract

Bumi Dipasena Sejahtera as part of Bumi Dipasena, which is managed by PT. Dipasena Citra Darmaja is the largest shrimp farming in Southeast Asia. Since operating in 1980, Bumi Dipasena has made production up to 200 tons/day. However, the current condition shows a decrease in total production to 30 – 40 tons/day from 16.000 operated ponds. Decreasing production is caused by declining water quality. This study aims to find out about nutrient loading and water suitability based on water quality criteria. Nutrient loading is determined from total production calculated from three different ponds. Suitability analysis was conducted by matching and scoring methods based on water quality measured at 7 sites in the inlet, outlet, and pond site. The result shows that nutrient loading has the highest value at the highest production. Water suitability analysis both of inlet and ponds include in suit marginal class (S3).
