Fingerlings used in the study were acquired from the Center for Freshwater Hatchery and Aquaculture, Muntilan, Central Java, Indonesia. The fingerlings had average weight of 3.43±0.50 g/fish. Completely Randomized Design was used in the experiments with 5 (five) treatment and 3 (three) repetitions. The experimental feed contained 31% of protein and 252.06 Kcal/g of energy. Various doses of the addition of papain enzyme were incorporated into the feed, those doses were A (0 g/kg feed), B (2 g/kg feed), C (4 g/kg feed), D (6 g/kg feed) and E (8 g/kg feed). Parameters of digestibility of protein (ADCP), relative growth rate (RGR), efficiency of feed utilization (EFU), feed conversion ratio (FCR), protein efficiency ratio (PER), survival rate (SR) and water quality were evaluated. The papain enzyme supplement significantly (P<0.01) influenced on ADCp, RGR, EFU, FCR, and PER, otherwise SR of catfish was insignificantly affected by the papain enzyme supplement. The best treatment result was the addition of 6/kg feed papain enzyme (treatment D). The study concluded that the optimum dose of the papain enzyme supplement for ADCp, EFU, FCR, PER and RGR were 5.65, 5.62, 6.0, 5.66, 6.0 g/kg feed respectively. Water quality during study was still in favorable condition for nurturing Sangkuriang catfish (Clarias sp).

A shortcut to get functional male, which proven difficult to be founded from natural catching, is masculinization. This research aimed to induce masculinization of tropical eel, Anguilla bicolor McClelland supplemented with various doses of 17α-methyltestosterone during a month culture in freshwater (0 ppt) or brackish water (10 ppt). The eel was grouped and fed with supplementation of 17α-methyltestosterone at various doses, depending upon treatments, namely 0 mg Kg-1 diet (control), 40, 80 or 120 mg Kg-1 diet. Eels size were similar, at approximately 16,78 g ± 0,62 in weight and 25,38 cm ± 0,15 in length were either culture in freshwater or brackish during the experiment for eight weeks. Sex gonad, based on anatomical histological structures, Eye Index and Fin Index were measured after time culture treatment achieved, as well as body length, weight, eye diameter and the length of the pectoral fin were measured. Results showed that supplementation 17α-methyltestosterone 80 mg/Kg diet culture in brackish water has the highest number of male (90%).

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.

Untreated effluent can cause environmental pollution, such as in groundwater reservoirs,because most is discharged into rivers. The aim of this research was to evaluate the bioremediation potential of indigenous fungi in liquid culture media with Indigosol Blue 04B (IB) batik effluent. The fungi isolates tested were Aspergillus sp. 1, Aspergillus sp. 2 and Aspergillus sp. 3, isolated from dye effluent soil and batik effluent, and compared to white rot fungi (Phanerochaete chrysosporium) as a positive control. The physiochemical properties of IB batik effluent before and after fungal treatment were investigated. All of these parameters before the fungal treatment were above the recommended standard values based on the Governor regulation of Yogyakarta Special Region No. 7/2010. The level of biochemical oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), total suspended solids (TSS), and electrical conductance (EC) was reduce by Aspergillus spp. The highest percentage reduction was achieved by Aspergillus sp. 3, namely 88.34% BOD, 89.11% COD, 75.77% TSS, 85.85% TDS and 71.21% EC, after 3 days of incubation. These results show that the positive control isolate had the lowest value.
