Abstract

Plant meals from Eichhornia crassipes and Salvinia molesta can be used as alternative ingredients for feed in aquaculture. The purpose of this study was to determine the effect of the use of plant meals as a feed on the growth of Pangasius. The experimental designed consist of three treatments and triplicates: P0: commercial feed (control); P1: feed with the addition of 25% Eichhornia crassipes; P2: feed with the addition of 25% Salvinia molesta. The results showed that plant meals in feed showed significantly different results on the growth of body weight, specific growth rate, and efficiency of Pangasius feed. The recommended treatment was the addition of Salvinia molesta  with a weight growth value of 3.84 g, a specific growth rate of 2.07%, and feed efficiency of 59.96%.

Abstract

The development of catfish culture affects increasing waste in the waters. Aquaculture waste containing high nutrients has the potential to damage the cultivation environment. The Biofloc system in catfish farming can break down NH3 waste into flocks that can be consumed directly by fish. This study aims to analyze the growth and survival rate of catfish in biofloc systems with different C:N ratios. The research design used was a completely randomized design (CRD) with four treatments and three replications. Siamese catfish seeds were maintained in an aquarium container size 40 x 30 x 30 cm for 40 days with treatment media A (maintenance without biofloc), treatment B C:N ratio 15, treatment C C:N ratio 20, and treatment D C:N ratio 25. The results showed that the biofloc system with different C:N ratios had significant effect on the weight growth, daily growth rate, and feed convertion ratio of catfish. The best treatment for growth and viability of catfish is C:N ratio 25.

Abstract

One effort made to improve the color quality of comet fish is to add canthaxanthin. Canthaxanthin is a red-orange pigment found in plants, fungi, bacteria, crustaceans, sea trout, and algae. This study aims to determine the optimum dose of canthaxanthin given in feed to improve comet fish' color quality. This research is also expected to be beneficial for fish farmers related to the use of canthaxanthin to improve comet fish' color quality. This study used 5 treatments with 3 replications. This research was conducted in April-June 2019 at the Aquaculture Laboratory, Department of Fisheries and Marines, University of Lampung. The parameters observed were color measurement using the Red Blue Green (RGB) method, converted into the Hue Saturation Brightness (HSB) value, color measurement by the scoring method, and water quality. The addition of canthaxanthin in diets with different doses showed the highest results in treatment C (P <0.05) on comet fish visual appearance. The results showed that the best dose in this study was the addition of canthaxanthin as much as 125 mg/kg of feed.

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

Marosatherina ladigesi’s original habitat is in the freshwater of South Sulawesi as endemic fish in the wallacea zone Indonesia, with a local name called beseng-beseng fish. M.ladigesi was already in the category of at threat of extinction.The purpose of this study was to investigate the effect of different protein levels on survival rate, growth performance, body protein composition and enzyme activity of protease, lipase and amylase of beseng-beseng fish. The research method was using Completely Randomized Design with three treatments and three replications. Treatment of the study: protein content of feed A: 40%, B: 50% and C: 60%. Fish maintenance takes 90 days. The results showed that protein content had a significant effect (P<0,05) on absolute body growth, specific growt rate, survival rate, body protein composition and protease enzyme activity of juvenile beseng-beseng fish. The best growth performance is obtained at 50% and 60% protein content, while the survival and body protein composition and the best protease enzyme activity at 60% protein content.

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).
