This research was conducted to determine the closed transportation system with biomass and water volume ratio that can support the osmoregulation ability of glass eel significantly. Glass eel was obtained from catching activities in the Cimandiri River, Pelabuhan Ratu (mean length 52.40+0.84 mm and weight 0.10+0.01 g) and acclimatized for 24 hours at salinity 6 mg L-1 and temperature 20°C gradually.The research design was a completely randomized design. The applied treatment was glass eel closed transportation system with various ratio of glass eel biomass (kg): water volume (L), i.e. 1:11; 1:12; 1:13; and 1:14 during 24 hours of land transportation and continued with a 3-day recovery period.The water was used refer to the above acclimatization method, with ratio the water part of pure oxygen in a plastic bag was 1:3. The measured parameters include survival rate, osmotic gradient, body hydromineral, and water quality in transport packaging and recovery medium. Survival rates were generated in the high range until recovery period (P<0.05), but the transportation method caused differences significantly (P<0.05) in osmotic response and hydromineral status (sodium, chloride, potassium, and water content), so that it will affect production performance in the next stage of culture. Ratio of glass eel biomass: water volume of 1:13 has been able to support the ability of osmoregulation glass eel to maintain homeostatic condition during the transportation until 3 days of recovery period. There was no drastic decline in physical and chemical value of water in the transport bag so it could reduce the mortality rate for 24 hours.

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.

Effluent from the local batik home industry is a serious problem, because the effluent discharge generated is spread in different places. 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. The study confirms the ability of indigenous fungi isolates in the remediation of IB batik effluent and their potential for future analysis in the treatment of all types of batik effluent.

Researchers have widely applied heat shock on zygote stadia of domesticated aquatic animals especially for the purpose of ploidy manipulation in fish to accelerate growth, intermediate products for the production of infertile seeds, providing prospective brood stock as well as the monosex population. This is certainly an interesting study to see how far the impact of heat shock on the early development stages. This experiment used a 42 0C heat shock for 2.5 minutes on the zygote at different initial time i.e. 28.5; 29; 29.5; 30 and 30.5 minutes after fertilization. All treated larvae and control were reared in a 25 liters plastic container at density of 5 larvae per liter. The results showed that high percentage of fertilization rate were 92.61 % to 96.32 % and hatching rate was 85.33 % without any abnormalities were achieved in the control. While in all treatments had a very low hatching rate of 4.12 % to 8.93 % with relatively high abnormalities of 12.36 % to 27.60 % and a significant differences (P<0.05) compared to controls, but survival rate, specific growth rate and feed conversion ratio after 30 days rearing period showed no significant difference (P>0,05). In terms of seed production, the heat shock treatment will limit 78 % to 82 % of larvae production.
