The goal of feed enrichment with amylolytic Lactic Acid Bacteria (LAB) was to get an optimal feed formula in stimulating the growth of freshwater crayfish (Cherax quadricarinatus). The research design used a completely randomized block design, which consists of 2 groups (Group I = probiotic HS7 with inoculum density 108 and Group II = probiotic HS7 with density 1010). Each group were given 4 different treatment (Feed A = protein 50%-carbohydrate 20%; Feed B= protein 40%-carbohydrate 30%; Feed C= protein 30%-carbohydrate 40%; and Feed D= protein 20%-carbohydrate 50%), with 2 repetition. The parameter observed in this study was daily growth rate and absolute growth. The result showed that Feed C, composed by protein 30%-carbohydrate 40% with LAB enrichment and inoculum density of 108 gives the best growth, with daily growth rate of ± 0.22-0.23 % each day and absolute growth of ± 13.10-13.20 gram in 75 days.

Blue swimming crab (Portunus pelagicus) is the important world fishery resource, but the crab larval rearing faces high mortality problem. The aim of the research was to compare survival and growth rate of larvae resulted from wild and domesticated broodstock blue swimming crab. Domesticated and wild broodstock were used to produce larvae. Domesticated broodstock was selected from repeated reared crab until third generation. Selection of the broodstock mainly based on the survival and growth rate. The wild broodstock was collected from Makassar Strait Sea. Larvae from the two sources of broodstock were reared in the conical tanks with density of 50 zoeas per liter. After reaching megalopa phase, then, the larvae were transfered into concrete tank completed with shelter and it were reared until crab phase. Crab phase was reared for 18 days, then these seed were released into the brackishwater pond for further domestication step. Larva from zoea to crab were fed with rotifer, artemia, fresh small shrimp and diet. The result showed that domesticated broodstock produced higher survival rate (P<0.05) larvae, faster larval stage changes (P<0.01) and uniform larval growth compared to the larvae from wild broodstock. It is clearly shown, the use of domesticated broodstock of blue swimming crab produced better larva quality and quantity than the wild broodstoock crab.Keywords : blue swimming crab, larvae, domestication, broodstock selection, faster growth

High density is one of the common consequences of intensive shrimp culture. High density can induce stress on the shrimp. Nonetheless, stress is not always harmful. In limited period, stress can trigger metabolism process and the hormonal system of the body. This study aimed to determine how high-density rearing causes stress on juvenile shrimp. The experiment consisted of three different density treatments, 60, 90 and 120 tiger prawn juveniles/m2 with two different weight groups, 3 to 10 g, and 11 to 16g as test animals. Each treatment with 3 replications, and 2 stocks were provided for treatment A, B, and C respectively (the stock was prepared to substitute the test animals at hemolymph sampling). Total Haemocyte Count (THC) was the main parameter used as a reference in assessing the response of tiger prawn juveniles to hight density. Based on the 3 treatments densities tested, the results showed that THC of the juvenile tiger prawns reared at 3 densities increased up to 24 h observation and decreased at 36 h observation. In fact, THC of the shrimp at the highest rearing density of 120 juveniles/m2 increased, which is one of the alleged treatment of tiger prawn juveniles tried to increase the tiger prawn's body defence. But the decline in THC was observed in the lowest rearing density of 60 shrimps/m2, in which the treatment did not cause stress on the tiger prawns in the lower weight group of 5 to10g (treatment A). In contrast, THC of the tiger prawn in the medium and highest rearing density (treatment B and C) drastically declined due to stress on tiger prawn juvenile and led to the tiger prawn dead. However, it is assumed that the tiger prawn juvenile that can adapt to the stressful condition, stress may become a stimulus that can trigger moulting, which is olso known as an indicator of growth.

The development of sustainable and economically sound practical diet in the coming years will depend on the reduction of fish meal and the increased inclusion of sustainable protein sources. Over the years, our laboratory has systematically reduced the inclusion levels of fish meal and other animal protein sources by using a range of alternative plant-protein sources. These diets may be further improved through the use of specialized proteins, supplements for limiting amino acids, enzyme and attractants. Good success has been seen with corn protein concentrates, advanced processing products of soybean meal, such as soy protein concentrates and advanced soy product (enzyme treated or fermented soy). Based on the results of our research, the proportion of animal meal can be reduced to 12 % in our current formulations without any detrimental effects on pompano performance and nutrient retention. In addition, the use of fermented soy or the combination of enzyme-treated soy with proper inclusion level of squid hydrolysates as an attractant has proven to improve the functional properties of SBM and lead to better liver and intestine condition of pompano. Considering the sizeable body of knowledge concerning nutrition for Florida pompano, all information taken from this species could be used as the starting point to develop better feed formulations for Silver pompano production in Indonesia.

Asian seabass (Lates calcarifer) aquaculture is potential developing industry in Australia and Indonesia. As the aquaculture industry intensifies, the occurrence of significant diseases becomes more likely. Hence, it is important to find better methods for controlling diseases in this industry. Research on mammals and fish have previously demonstrated the potential benefits of dietary nucleotides to enhance immune function of the animal to combat diseases. However there is still very limited study of this subject in Asian seabass. This study aims to investigate the role of dietary nucleotides on the growth and immune responses of Asian seabass. Juvenile Asian seabass with average weight of 13.8±1.29 (mean ± SD) g were fed three different diets containing either Optimun® nucleotides or a mix of pure nucleotides at 0.25% per kg feed and one basal diet (nucleotide free diet). Fish were fed at 3 % BW per day for 28 days. Results showed that dietary nucleotides did not significantly effect the growth, survival rate, and immune responses of the fish. However Optimun® diet gave higher result in terms of growth, leucocrit level, lysozyme activity and respiratory burst activity of head kidney leucocyte compare to basal and the mix of pure nucleotide diets.

In this study, the effects of oral administration of probiotic Bacillus sp. D2.2 and prebiotic from sweet potato extract on growth performance and resistance against Vibrio harveyi in Pacific white shrimp (Litopenaeus vannamei) were investigated. During 32-day feeding experiment, 360 individuals of Pacific white shrimp (PL15) with initial weight of 0.02 ± 0.002 g were fed with basal diet as control (A); supplemented with 6% probiotic and 0% prebiotic (B); 6% probiotic and 2% prebiotic (C); 6% probiotic and 4% prebiotic (D). At the end of feeding trial, weight gain (WG), average daily growth (ADG), feed conversion ratio (FCR), and survival rate (SR) were assessed. WG, ADG and FCR of the shrimp were significantly better in treatment D than those of the shrimp in other treatments. Control and treatment D as the best feeding trial were selected for challenge test with infectious V. harveyi. Survival rate and mean time to death (MTD) of the shrimp fed the supplemented diet were not significantly different (P>0.05) to the control. Infection levels in shrimp were evaluated using morphological scoring methods. Infection levels of V. harveyi in shrimp fed the diet were lower compared to the control.

The aims of this research were to determine the hatching performance of snakehead fish egg which incubated at different water temperature. This research had been conducted in the Fish Breeding Unit “Batanghari Sembilan”, Indralaya South Sumatera Indonesia. This research was an experimental research with 5 treatments of water temperature P1 (26 ± 0.5°C), P2 (28 ± 0.5°C), P3 (30 ± 0.5°C), P4 (32 ± 0.5°C), P5 (34 ± 0.5°C) and 3 repetitions. The results showed that incubation period needed at P1: 30.01 hours, P2: 28.02 hours, P3:23.13 hours, P4: 21.03 hours, P5: 20.12 hours. The best treatment for hatching rate, normality and survival rate were P2 treatment, 86.33%, 100% and 97.3%, respectively. Even though the fastest incubation period was the P5 treatment (20.12 hours). Water quality of the research was intolerance range, pH (4.17-5.32) and Dissolved Oxygen (6.23-6.71 mg.L-1). Based on the results acquired, incubation temperature at 28 ± 0.5°C produced the best hatching rate, normality, and survival rate.

Blue swimming crabs (Portunus pelagicus) from Makassar Strait have some variations in color and pattern of spots on the carapace. The purpose of this study was to analyze the habitat preferences blue swimmer crab species complex from Macassart Straits. Crabs were grouping based on the difference of color and pattern of spots on the crab carapace to identify the variety of crabs. Habitat was observed salinity, depth, and substrate type. The results of PCA analysis showed a tendency of each population occupies a different base substrates (P<0.01). Substrate type also correlated with depth and salinity. The conclusion of this study is the difference in the color and pattern on the carapace thought to be different species or varieties and they occupy different habitats. Preferences of the different habitats for different population groups are very important information for the development of blue swimming crab aquaculture in the future.
