This research aimed to determine the ability of quorum sensing inhibitor compound thiophenone to protect catfish (Clarias sp.) larvae when challenged with the pathogenic Aeromonas hydrophila. This research was conducted at Fisheries Laboratory, Faculty of Marine Science and Fisheries, Udayana University, from December 2019 to January 2020. The experiment was setting up with four treatments and three replications for each treatment. 10 larvae of catfish were maintained in aquarium 15 cm × 15 cm × 20 cm filled with 1 liter of freshwater and used aeration for oxygen supply. The treatments were treatment A (control), treatment B (addition of A. hydrophila 106 cfu/ml), treatment C (addition of thiophenone 10 µM), and treatment D (addition of A. hydrophila 106 cfu/ml and thiophenone 10 µM). The results showed that the addition of thiophenone 10 µM increased the survival of catfish larvae up to 73% when challenged with A. hydrophila. That was significantly difference (P<0,05) compare to treatment B with survival rate of 43% within 3 days of culture period. Although it was not statistically different (P>0,05), the highest absolute weight and length were found in treatment A of 0,47 g and 0,50 cm, respectively, while the lowest absolute weight and length were found in treatment B about 0,23 g and 0,17 cm, respectively. The water quality such as temperature, pH and DO were still within the range that supported the growth and survival of catfish larvae during this study.

ABSTRACT The development of lobster farming in floating net cage in Ekas Bay caused an environmental degradation such as decrease water quality due to some aquaculture wastes. The purposes of this study were to determine the status of water quality and their effect on growth and survival rate of lobster reared in floating net cages (FNC) in the Ekas Bay, West Nusa Tenggara Province. Water sample collection and handling referred to the APHA (1992). Analyses of water quality data were conducted using Principal Component Analysis. Determination of the water quality status of Ekas Bay was performed with STORET system. Multivariate analyses were used to determine the relationship between water quality, growth, and survival rate of lobster reared in FNC. Results showed that Ekas Bay water quality status was categorized in class C (medium contaminated), which exceeded some quality standard parameters such as ammonia (0.3 mg/l), nitrate (0.008 mg/l), and phosphate (0.015 mg/l). During lobster farming activities feeding with trash fish for 270 days, we obtained daily growth rate of  0.74% (lower than normal growth rate of 0.86%), survival rate of 66% (lower than normal survival rate of 86.7%), and feed conversion ratio of 11.15. Ammonia was found as a dominant factor reducing growth  and survival rate of lobster reared in FNC. Keywords: water quality, lobsters, growth, survival, Ekas Bay

Research Experiment

Live foods such as rotifers and Artemia are commonly used as foods in larval rearing of mud crab (S. olivacea). However, the continuous availability and nutritional consistency of live foods are difficult to control. Thus, the development of artificial diets to partially or fully replaced live foods is needed to overcome the limitations of live foods. The purpose of this research was to determine the best stage at which mud crab larvae can be weaned from live foods to artificial diets. The research experiment consisted of: treatment-1, the larvae were fed with live foods from zoea-1 to megalopa stages as the control treatment; treatment-2, the larvae were fed with artificial diet from zoea-2 to megalopa stages; and treatment-3, the larvae were fed with artificial diet from zoea-3 to megalopa stages. In treatment-4, artificial diet was given from zoea-4 to megalopa stages. The growth and survival rate of larvae in treatment-1, 3, and 4 were not significantly different (P>0.05) but significantly different with treatment-2. Based on the present results, this study suggests that artificial diet can be given to mud crab larvae (S. olivacea) from the third zoea stage.

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.
