PERTUMBUHAN KEPITING BAKAU Scylla olivacea DENGAN RASIO JANTAN-BETINA  BERBEDA YANG DIPELIHARA PADA KAWASAN MANGROVE

Mudcrab fattening is potential to develop in mangrove areas. The aim of the present study was to determine the best ratio of male and female in fattening of mud crab in the mangrove area. Research was conducted in the mangrove areas of Pangkep Regency, South Sulawesi Province. Test animals used were mud crab S. olivacea male and female measuring weight of 250 ± 10 g and were stocked at a density of 10 animals/cage. The bamboo cages measuring length, width, and height of 1.0 x 1.0 x 1.0 m3 were placed in the mangrove areas. Feed used was trash fish at 10% of the biomass with the feeding frequency of two times a day ie morning (30%) and afternoon (70%). The study used a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The ratio of male and female crabs were 7:3; 6:4; 5:5; 4:6 and 3:7 crabs/cage, respectively. Results of analysis of variance showed that the treatment with the different ratio of male and female was not significant (p> 0.05) on the survival rate of crab, but was highly significant (p <0.01) on the absolute and daily growth rate. The resulting survival rate ranges from 93.33 to 100%, absolute growth and the highest daily growth rate of crabs produced at a ratio of males and females (7:3) and (6:4) crabs/cage ie: 56.99 and 1.35; 56.25 g and 1.36%/day, while the lowest was in the ratio (3:7) crabs/cage ie: 28.97 g and 0.73%/day.

The study aimed to determine the growth and survival of Litopenaeus vannamei shrimp with the application of probiotics to different stocking densities. The study was conducted from May to June 2018 at the Balai Benih Ikan Pantai (BBIP) Ghonebalano, Duruka District, Muna Regency, using a Completely Randomized Design (CRD) with three levels of solid stocking treatment namely treatment A is 18 individu per container, treatment B is 24 individu per container and treatment C is 30 individu per container with three replications. Data analysis using Variance Analysis (ANOVA) at the confidence level of 95% (α 0.05). The results showed that the highest daily growth was obtained at 24 individual densities of 5.88% per day, compared to 18 individual densities of 5.86% per day and 30 individual densities of 5.74% per day. The highest absolute growth is obtained at 24 individual density of 2.43 g per individu, then 18 individual density of 2.15 g per individual, and the lowest at 30 individual density of 2.02 g per individual. Survival at a density of 18 individual and a density of 24 individual at 88.89%, while a 30-ind density of 86.67%. Analysis of variance (α 0.05) showed that the application of probiotics to different stocking densities had no significant effect on the daily growth rate of vannamei shrimp (p<0.939), absolute growth of vannamei shrimp (p<0.080), and survival of vannamei shrimp (p<0.744).

ABSTRACTThe research was conducted at the Aquaculture Laboratory, University of Lampung in May to July, 2018. The aim of this study is to determine the effect of substitution of fish meal with catfish head flour on the growth of catfish, and head flour dosage the best for catfish growth. The study used a Completely Randomized Design with 3 treatments and 3 replications A (100% fish meal), B (70% fish meal and 30% catfish flour), and C (40% fish meal and 60% catfish flour). Parameters observed included absolute growth, daily growth rate, protein retention, feed convertion ratio (FCR), survival rate (SR), and supporting parameters that is feed cost and water quality. The data obtained were analyzed by variance and continued with smallest real difference test with a 95% confidence level. The results showed that the proportion of catfish head flour in artificial feed had an effect on absolute weight growth and daily growth rate (P, 0.001). The proportion of the use of 30% starch in the feed of catfish has a real influence on absolute growth (40.25 ± 5.67 g), and daily growth rate (0.67 ± 0.09 g/day).Keywords : Catfish, catfish head waste, substitution, feed, growth

The research is aimed to knowthe best concentration of Keong Masshell mealto increase the growth rate and survival rate of freshwater lobster. The experimental research used completely randomized design with 4 treatments and 3 replications. The treatments were K (the commercial shrimp artificial feed), A (the artificial feed with 5% the shell meal of Keong Mas), B the artificial feed with 7% the shell meal of Keong Mas), and C (the artificial feed with 9% the shell meal of Keong Mas). The test shrimp were the freshwater Lobster sized 3.5 – 4.5 cm and was fed at satiation twice a day. The daily growth rate, the feed efficiency, survival rate, and water quality has been observed. The results of research showed there were not a significantly different between the treatments (P>0.05) against the daily growth rate, the feed efficiency, and survival rate of the freshwater Lobster.The shell meal of Keong Mas could be as a Calcium source. The Keong Mas meal can subtitute 100% fish meal of artificial feed thus could be the alternate standard material of the fish meal of the freshwater Lobster feed.Water quality in aquaculture media still on the range of feasible for the freshwater Lobster culture.
