Catfish (Clarias gariepinus.) is one of the leading commodities that are widely cultivated in Indonesia. The current development of the aquaculture industry, which leads to intensive cultivation systems with an increase in stocking and high amount of feed, causes an increase in organic waste that can reduce water quality. Phytoremediation is one way to stabilize pollutants, both organic and inorganic compounds, through aquatic plants. Water hyacinth (Eichornia crassipess) is one aquatic plant that can reduce total nitrogen up to 73.05%. This study aims to analyze the effect of water hyacinth (E. crassipess) as a phytoremediator on TAN reduction, survival rates, and growth of catfish (C. gariepinus) seeds. This study used a Completely Randomized Design (CRD) method with four treatments and four replications, namely P1 / control (without water hyacinth), P2 (without replacement of water hyacinth), P3 (alternation of water hyacinth every 21 days), and P4 (alternation of water hyacinth) every 14 days). The results showed that the P4 treatment (alternation of water hyacinth every 14 days) gave the lowest TAN content 0.01 mg / L and provided the highest survival rate of 89.88%, as well as the absolute weight and length growth of the most catfish seeds height, i.e., 9.80 g, and 5.50 cm, respectively.

Catfish (Clarias gariepinus) was cultured with an aquatic plant, water hyacinth/eceng gondok  (Eichornia crassipes), kangkung air (Ipomea aquatica) or kapu-kapu (Pistia stratiotes) in concrete ponds, for 3 months. Catfish cultured without aquatic plant was used as a control. The experiment was carried out to evaluate the survival rate as well as the growth of fish and aquatic plants.The survival rates of catfish cultured with I. aquatica, E. crassipes, and P. stratiotes were 76, 87, and 98%, respectively. In addition the survival rate of catfish cultured without any aquatic plant was 93%. The weight gain of catfish was 14,1-16,2 kg per pond. Whereas, the total weight gains of aquatic plant were 37,0,  27,7 and 7,7 kg per pond for E. crassipes, P. stratiotes, and I. aquatica,. Respectively. Dissolved oxygen, and the concentrations of NH3, NH4+ and PO43- in water with aquatic plants were higher than that of in water without aquatic plant. However, the concentration of CO2 was higher in water with aquatic plant.

Management of aquaculture wastewater is still the major problems in fisheries, especially in intensive systems. Intensively aquaculture activities often increase organic matter and nutrients (N and P) in the water.  The study was conducted to evaluate the phytoremediator performance of Echinodorus amazonicus and Echinodorus palaefolius in removing inorganic nitrogen and orthophosphate from aquaculture wastewater with the recircula­tion system. This study used a completely randomized design with three treatments and 3 replications. The treatments of this study were P1: E. amazonicus,  P2: E. palaefolius and P3: control (without aquatic plants). The tested fish were elvers  which average weight 6.98 ± 0.19 g,  and  fish density was 4 gL-1. Elvers reared in an aquarium that containing 48 L in  a recirculation system. The paste feed which protein level of  45.25% was given at satiation 3 times/day. Elvers reared for 60 days. The results showed that E. palaefolius significantly reduced concentrations of total ammonia nitrogen (TAN), nitrite (NO2), nitrate (NO3) and orthophosphate (PO4) with an efficiency of 27.10 ± 2.42%; 45.03 ± 9.77%; 20.94 ± 1.29% and 14.19 ± 3.05%, respectively higher than E. amazonicus and control. The best result of elver’s performance (SGR and FCR) was in treatment P2 (E. palaefolius), i.e.  1.19 ± 0.18% and 1.57 ± 0.30. Based on the results of this study, it can be concluded that the use of E. palaefolius as phytoremediator in eel culture with recirculation system can removed inorganic nitrogen and orthophosphate more optimal compared to other treatment.

The objective of this research was to evaluate the supplementation of turmeric in the diet on antioxidant status and growth performance of African catfish (Clarias gariepinus) in zero water exchange condition. This study used a completely randomized design with 4 treatments and 4 replications. Each treatment consisted of feed supplementation turmeric at dosage of 0; 2.5; 5 or 7.5 g kg-1 diet. One hundred catfish juvenile (5.95±0.05 g) were stocked in intermediate bulk container (IBC) tank (1×1×1 m3) and rearing in zero water exchange condition for 60 days. Catfish were fed at satiation twice a day, in the morning and evening. The results showed that an increase in antioxidant content in catfish fed with the addition of turmeric, which simultaneously also reduced the percentage of liver damage. The parameters of liver damage can be seen from several parameters i.e. pale liver, droplet fat and fat content in the addition of turmeric treatment is lower than without the addition of turmeric. However, catfish fed with the addition of turmeric did not show significant results in terms of growth performances.

<p>Seurukan fish (<em>Osteochilus vittatus</em>) has many advantages, besides the fish also has disadvantages which are the slow growth, so the temperature shock of triploidization technique was expected to solve the problem.   The objective of the present study was to obtain an effective temperature to increase of triploidization success of <em>seurukan</em> fish (<em>Osteochilus vittatus</em>). The experimental method and completely randomized design model were used in this study. Five levels of temperature shocks at three replicates were tasted: 4℃ (cold), 6℃ (cold), 28℃ (normal), 35℃ (heat) and 37℃ (heat). The sperms and eggs were fertilized in the plastic jar then a total 100 of fertilized eggs (zygotes) were taken randomly 3 minutes after fertilization and soaked in respective temperature for 90 seconds, and then incubated in incubation jars at the water temperature of 28-29℃. The results showed that the temperature shock gave the significant effect on the hatching and the success of triploidization success (P˂0.05), but did not give the significant effect the fertility and survival rates (P&gt;0.05). The triploid fish can be achieved using cold and heat shock, but the higher triploid fish was recorded at 37℃ was the best temperature recommended for triploidization of <em>Seurukan</em> fish.</p>

The G2 trangsenic Mutiara catfish (Clarias sp.) (MTG) is a Mutiara catfish that is inserted with the CgGH gene (Clarias gariepinus Growth Hormone) through the transgenesis. The effect of transgenesis stimulates gonad growth of G2 transgenic Mutiara catfish (Clarias sp.) faster than non-transgenic fish. Study aimed to analyze the maturity of the gonads and the spawning ability of female G2 transgenic Mutiara catfish (Clarias sp.) to obtain superior broodstock candidates. Experimental method with completely randomized design (pair of parents used as treatment and repeated four times) for spawning was used for this study. Three pairs of parent G2 were crossed semi-artificially as treatment A (female 1 MTG G2 crossed with male 1 MTG G2), B (female 2 MTG G2 crossed with male 2 MTG G2) and C (female 3 MTG G2 crossed with male 3 MTG G2). The results showed that the performance of female G2 transgenic Mutiara catfish (Clarias sp.) (treatment A, B and C) was higher given non-transgenic with an average relative fecundity of 82,438 eggs / kg of broodstock, an average egg diameter of 1.76 mm and an average egg weight 1.75 mg. These indications suggest that GH transgenesis increases gonadal maturity. The gonad maturity profile reached the stage of complete maturity (full ripe) compared to Sangkuriang catfish (Clarias gariepinus) (immature gonads). Therefore it is necessary to compare the reproductive performance of G2 transgenic Mutiara catfish (Clarias sp.) with non-transgenic fish (Sangkuriang) as candidates for superior broodstock of catfish.

An experiment to evaluate the effectiveness immunostimulant and bacterin on humpback grouper have been conducted at the Disease Laboratory of Research Institute for Mariculture, Gondol, Bali. The experiment was designed in completely randomized design with four treatments in duplicates. Two hundred of humpback grouper juveniles (15-18 cm of total length, 55-65 g of body weight) were injected intraperitoneally with (A) bacterine at 107 cfu/kg body weight (BW), (B) peptidoglycan at 100 mg/kg BW, and (C) immuno star at 100 ml/kg BW, (D) control. The fish were then challenged with VNN by intramuscular injection at 10 days post treatment. Results showed that survival rates of juvenile after challenged with VNN were 60.00% (B & C), 53.34% (A), and 1.67% (control). Parameters of non-spesific immune respons showed that phagocytic activities were 17.56% (B), 17.55% (C), 13.11% (A), and 9.33% (control). In addition, lisozyme activities were 1.64 cm (B), 1.58 cm (C), 1.55 cm (A), and 1.46 cm (control). Immunostimulant and bacterin stimulated non-specific immune response, and increased survival rate of humpback grouper juvenile.
