The sustainability of the shrimp aquaculture depends largely on disease control and the health status of shrimp. Probiotics, which make shrimps healthier and more resistant to pathogens, are promising countermeasure for shrimp diseases. In this study, the effects of the marine purple non-sulfur photosynthetic bacterium (PNSB) Rhodovulum sulfidophilum on Marsupenaeus japonicus (kuruma shrimp) growth and survival were examined in 177 m2 aquaria (140 tons of water) for 70 days. The shrimp received feed containing 0.01 % fresh weight (106 colony forming unit/g) of R. sulfidophilum cells. The survival rate significantly improved (P < 0.001) (R. sulfidophilum-fed = 81.9 %; control = 71.5 %), the feed conversion rate improved (R. sulfidophilum-fed = 1.83; control = 2.11), and there was no difference in the shrimp average body weight. The approximate bacterial cell cost was $0.003 to $0.005 per 1 kg feed, indicating that the R. sulfidophilum approach is economically feasible and a promising candidate for probiotic bacteria in shrimp aquaculture.

This study aims to determine the effect of different doses of booster grotop in feed on the growth and survival of Asian Redtail (Hemibagrus nemurus) maintained in peat swamp media. This research was conducted from 27 March - 05 May 2020 at the Laboratory of Aquaculture Technology, Faculty of Fisheries and Marine, University of Riau. The container used was an aquarium measuring 60 cm x 40 cm x 40 cm as many as 15 units with a stocking density of 12 fish/60 L. This study used a completely randomized design method (CRD) one factor with five levels of treatment and three repetitions. The level of treatment applied in the study was P0 = without giving Boster Grotop (Control), P1 = dose of Boster Grotop 25 g/kg of feed, P2 = dose of Boster Grotop 30 g/kg of feed. P3 = dose of Boster Grotop 35 g/kg of feed and P4 = dose of Boster Grotop 40 g/kg of feed. The results showed that giving boster grotop with different doses in the feed had a significant effect (P<0.05) on growth but had no significant effect (P>0.05) on the survival rate of the Asian Redtail seeds. The best treatment was found at a boster grotop dose of 40 g/kg of feed, which produced protease enzyme activity (0.1731 IU/mL), total weight growth (5.11 g), total length growth (3.73 cm), specific growth rate (3.67%), feed efficiency (72.30%), feed conversion (1.38), survival rate (86.11%).

Abstract. Nugroho RA, Hardi EH, Sari YP, Aryani R, Rudianto. 2019. Growth performance and blood profiles of striped catfish (Pangasianodon hypophthalmus) fed leaves extract of Myrmecodia tuberosa. Nusantara Bioscience 11: 89-96. The application of plant extract in the aquaculture field is gaining momentum. This study aimed to determine the effects of M. tuberosa Jack leaves extract on the growth performance and blood profiles of striped catfish (Pangasianodon hypophthalmus). 400 fish with an initial average weight of 1.54 ± 0.02g were randomly divided into five groups and fed with different concentration of M. tuberosa Jack leaves extract (0.25, 0.5, 1, 2%) and control diet for 80 days. Growth performance, feed conversion rate, feed efficiency, survival rate, morphometric, and hematological profile of the fish were evaluated at the end of the trial. The results found that fish fed 0.5-1% concentration had significantly higher (P<0.05) growth, feed conversion rate, feed efficiency, morphometric value, survival, white blood cell, hemoglobin, neutrophil, lymphocyte, and monocyte than control. Meanwhile, supplementation of 2% MTE in the diet of fish reduced growth, feed utilization, viscerosomatic index, and morphometric values but increased red blood cell. All the supplemented diets decreased platelet of fish. The findings indicated that supplementation 0.5-1% of MTE is beneficial to the growth and blood profile of fish through the increment of growth indices, feed utilization, white blood cell, hemoglobin, neutrophil, lymphocyte, and survival rate of fish.

Here, we investigated the inhibitory effects of the biodegradable, water-insoluble polymer poly-hydroxybutyrate-co-hydroxyhexanoate (PHBH) and its two constituent monomers, the hydroxyalkanoic acids 3-hydroxybutyrate (3HB) and 3-hydroxyhexanoate (3HH), on the growth of the shrimp-pathogenic bacterium Vibrio penaeicida. In vitro experiments revealed that 3HH showed greater growth inhibitory activity than 3HB against V. penaeicida. In addition, the activities of hydroxyalkanoic acids were pH dependent, being greater at pH 6.0 than at pH 7.0. Investigation of the pH of the shrimp gut revealed a pH range of 5.9–6.7 (mean 6.29 ± SD 0.20), indicating that the physiological environment was suitable for 3HB and 3HH to exert their inhibitory activities against V. penaeicida. In vivo bacterial challenge experiments revealed that survival rates in kuruma shrimp (Marsupenaeus japonicus) infected by V. penaeicida were significantly increased in shrimp reared on feed containing PHBH (0.1%–5% w/w PHBH) compared with that in shrimp reared on standard diet alone. Supplementation with PHBH had no significant effects on three shrimp growth parameters: increase in body weight, daily feeding rate, and feed conversion ratio. These results suggest that supplementation of standard diet with PHBH will increase shrimp resistance to infection by V. penaeicida, thereby increasing shrimp aquaculture productivity.

Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density information on tilapia seeds measuring 2-3 cm as an alternative to using tilapia (O. niloticus) seeds 7-9 cm in size so that they can be developed in Batur Lake. The research was conducted in January - March 2020 in the floating net cages in Trunyan Kintamani village, Bangli, Bali. The research used a completely randomized design method with three treatments and three repetitions. The Tilapia seeds used are 2-3 cm with different stocking densities, 100 ind/m3, 150 ind/m3, and 200 ind/m3. The parameters observed were SGR (Specific Growth Rate), absolute growth, SR (Survival Rate), FCR (Feed Conversion Ratio), and water quality including temperature, DO, pH, TDS. The results of this study indicated that stocking density did not have a significant effect on the growth and survival rate of tilapia seeds, because the temperature was too cold so that the tilapia seeds failed to adapt properly at the beginning of stocking and the physiological conditions of the fish were disturbed so that the fish experienced stress and went to died. Water quality parameters measured include temperature with a range value of 25.86-25.880C, pH with a range value of 9.08-9.13, DO (Dissolved oxygen) with a range value of 7.9-8 mg/L, and TDS (Dissolved solids) with a range value of 1040.25-1041.58 mg/L.

Abstract Lobster is among freshwater crustaceans which is potentially cultivated in aquaculture system. This present study was conducted to determine the growth and survival rate of freshwater lobster Cherax quadricarinatus fed different forage feed. The experimental methode used a completely randomized design consisted of 4 treatments in triplicate: commercial diet (PL), commercial diet and carrots (PW), commercial diet and potatoes (PK) and commercial diet and sweet potatoes (PU). The experimental lobsters were 5-7 cm in size and 6-8 g in weight. Results indicated that forage feeding can affect the total weight and length, weight gain, specific growth rate and survival rate of lobster. Data showed the best weight gain and specific growth rate were found in PW (34.37±0.30%) and (1.05±0.03%), respectively. The lowest survival rate was seen in PU at 86.67%. However, the best feed conversion ratio gained by PL at 1.74±0.09. This study suggested that the combination of commercial diet with carrots provided the best growth performances in freshwater lobster Cherax quadricarinatus.

Availability of good-quality shrimp feed is an important factor of shrimp increased production. High protein feed can be generated by adding raw materials that contains high protein. One of the raw materials that contains high protein is earthworm meal (Lumbricus sp.). This research goal was to study the influence of the substitution of fish meal by earthworm feed with different proportions toward growth and survival rate of tiger shrimp larvae (Penaeus monodon). The experimental design used Completely Randomized Design (RAL) consists of five treatments with three replications: Feed test A (25%  earthworm meal + 75% fish meal), feed test B (50% earthworm meal + 50% fish meal), feed test C (75% earthworms meal + 25% fish meal), feed test D (100% earthworms meal) and feed test E (commercial feed). Results showed that the tiger shrimp which given feed test E is the best result for tiger shrimp growth with 0.480 ± 0.076 grams/individual, while feed test B was the best result for tiger shrimp survival rate with 82 ± 3.46%., and on the feed test D was the best result for tiger shrimp feed conversion rate with 4.0 ± 0.17. Based on results of statistical tests showed that the substitution of fish meal with earthworm meal did not give significant effect on growth and survival rate of tiger shrimp.
