The aim of the study was the effect of white shrimp polyculture, and seaweed in an effort to increase the growth and survival of white shrimp and seaweed and control the abundance of phytoplankton. The research method was a completely randomized design with 4 treatments and 3 replications namely T1 (10V + 10 cm RL): given 10 seeds / m2 white shrimp and seaweed 10 cm spacing, T2 (10V + 20RL) = 10 seed / m2 white shrimp and seaweed planting distance of 20 cm, T3 (10V + 30RL) = 10 seed / m2 white shrimp and seaweed distance 30 cm, T4 (10V + 40RL) = given 10 seed / m2 white shrimp Vannamei and seaweed plant distance 40 cm), and observed abundance of plankton used sample collected (April-August 2018) from site (T1),(T2),(T3) and (T4) of this penculture pond. The weight of Gracillaria sp 150 g / to treatment with the long line system was placed around the plot of waring area of 1 m2 in the pen culture pond area of 300 m2. Data collection included: absolute weight growth, survival, FCR, and water quality data (temperature, salinity, pH, O2, NO2, NH3). Data were analyzed for variance and to find out the middle values between treatments, Tukey Test analysis was performed. The results showed that the presence of white shrimp and seaweed polyculture engineering at different plant distance had a significant effect (P <0.05), on growth and survival and effected community structure and abundance of phytoplankton. The highest absolute weight growth in white shrimp (L. vannamei (g) on T4 (27.53 ± 0.04 g), white shrimp survival (90.25%), white shrimp of FCR (FCR = 1.19 ± 0.05b), and also on seaweed Gracillaria verocosa on T4 has the highest growth of absolute weight of seaweed (G. verocosa) (g), namely 2905.05 ± 7.5b, survival of T4 seaweed (93.33 ± 0.25% and abundance of phytoplankton

Aquaponic cultivation systems require good care and management. Aquaponics that are not managed properly have great potential to cause failure in aquaponic cultivation itself. To simplify management, a system that can simplify the process is needed. The purpose of this research is to create a system that can help manage aquaponic cultivation. The system has a built-in aquaponic condition monitoring feature via an installed sensor. The conditions monitored by this system are conditions of air temperature, humidity, water temperature, light intensity, level of turbidity of water, and height of fish feed at the feedlot. The system has two automation features. The first automation feature is the automation of fish feeding with a certain time lag. The second automation feature is the automation of the water heater engine. Water heater engine will be turned on or off at a certain temperature. The system also features an engine control feature in aquaponics that includes a water pump engine, an aerator engine, and a water heater engine. System monitoring, automation and control features can be accessed by users via the web. Testing of the system has indicated that the system is functioning properly in accordance with the objectives. The algorithm is correct, so the system output matches the expected output.

Up regulation of heat shock proteins (HSPs) in organisms can be detected in response to many kinds of stressor. Recently there were few studies have focused on the three kinds of heat shock proteins (HSPs) and antioxidant enzyme activity after biofloc stress. The objective of this study was to investigate the effect of different biofloc volume on the expressions of (LvHSP60, LvHSP70, and LvHSP90), the activity of superoxide dismutase (SOD) and phenoloxidase (PO) of the L. vannamei after biofloc addition. PL10 L. vannamei were divided into three groups: precondition, biofloc stress (5mL/L, 10mL/L, 15mL/L), and recovery. The gene expression results showed that the expressional levels of LvHSP60, LvHSP70, and LvHSP90 were increased significantly in 6h treatment and tend return to normal conditions after 48h treatment. Superoxide dismutase activity was reduced during treatment and phenoloxidase activity was elevated slightly after 12h to 24h and tend to pretreatment level at recovery periods. All of these HSPs expression reverted to normal levels 6h after the recovery period. The results indicated that different expression patterns of the three HSPs. HSP60 have a longer and higher protection expression after 12h treatment than HSP70 and HSP90. HSP90 was more sensitive in 6h at all treatments than HSP60 and HSP70. It is concluded that supplementation of biofloc with the volume of 5-15mL/L caused Hsp protection in L. vannamei PLs at the first 6h to 48h treatment and increased phenoloxidase activity at 24-48h treatment and reduced survival rate of the white shrimp.

Interspecific hybridization of mud crab Scylla spp has been successfully conducted in controlled tanks. However, there is no information yet available about the male size S. tranquebarica is capable to copulate with female of S. olivacea. The objectives of the experiment is to find out the male size of S. tranquebarica that willingly copulated with newly molted female of S. olivacea. Twelve individual of adolescent female of S. olivacea were reared individually in the conical fibreglass tanks each of 400 L volume. In another tank, 12 adult male S. tranquebarica with various size (200-400g/ind.) were also prepared. The crabs fed with chopped trash fish in the morning (7.00 am) and afternoon (17.00 pm) at 5% of the total crab biomass. Each newly molted female is transfered to the copulation tank and three male of different size also stocked at the copulation tank, then wait until one of the three male do copulation with female new molt. The size of copulated crabs (body weight, carapace with, and carapace length) were recorded. The female crabs sizes were measured before and after molting, whereas, the male crab sizes were measured soon after mating process has finished. Post mating, the female crab then reared individually in the tank until spawned. The result showed that male S.tranquebarica of >300g individual weight are preferable to copulate with female S. olivacea, and contrary none of male crab with size <300g do succsess mating The time period from mating until gonad maturity stage IV for the S. olivacea in this study range between 59-103 days.

Institute for Mariculture Research and Fisheries Extension have been able to spawn yellowfin tuna in the floating nets cage (FNC) since 2015. However, the number of juveniles produced is still low due to the high mortality of larvae at first 10 days old and when metamorphosed into juveniles. The inner wall color of tank is suspected to affect the survival of early larvae stage. The purpose of the study is to get suitable inner wall color of the tank to increase growth and survival rate. Eggs harvested from FNC and stocked 20 eggs/L in 5 Fiberglass Reinforced Plastic tanks, volume of 6 m3. Treatments were: A. Gray, B. Blue, C. Yellow, D. Black, and E. White, 3 replication. Hatching rate of eggs at treatment (A) was 60.39%, blue (B) 76.64%, yellow (C) 61.74%, black (D) 71.08% and white (E) 69.19%. Daily observation of Yellowfin tuna larvae kept in blue, yellow and white inner wall tank are more patched in the corner near the surface of the tank. While the larvae in the gray and black inner wall tank were distribute evenly either in the surface layer and water column. The survival rate of juvenile in black inner wall tank is better than others color treatments, although statistically does not significantly different.

The utilization of coastal area nowadays is commonly used for vannamei prawns aquaculture, either with traditional technology ?plus? and intensive technology. The regency of Indramayu is a district in which coastal regions are now utilized to vannamei prawns aquaculture. The uncontrolled development of this aquaculture farming will cause an impact on the surrounding environment, and will eventually threaten other environment sectors in the coastal areas of Indramayu. This research was aimed to calculate the carrying capacity of Indramayu sub-district coastal area. The results of the measurement of the coastal area in Indramayu showed that the aquaculture activities were not exceeding its carrying capacity. It is demonstrated by the high productivity of biomass, which is 21 000 tons of vannamei prawn per year from the ideal productivity of only 1959 tons per year. This condition could be occurred due to the water quality in the coastal of Indramayu is still relatively good with the quality status of mild pollutants.

This study aims to determine the effect of salinity on the growth of microalgae C. vulgaris cultured in 5% concentration of water hyacinth liquid organic fertilizer. The research used a completely randomized design with four salinity treatments at 30, 35, 40 and 45 ppt in triplicates. The volume of culture media was 150 mL that consisted of 142.5 ml of sterile sea water and 7.5 ml of water hyacinth organic fertilizer. The increase in microalgae cell density was observed every other day using haemocytometer under light microscope. The culture was harvested after they reached stationary phase at day 8. Culture age (p= 0,00<0.05) and salinity (p= 0,00<0.05) affected the growth, dry weight and biomass productivity of C. vulgaris. Cells density and yield in all salinities tested was significantly different (p= 0,00<0.05) at stationary phase of growth. Higher cell density, specific growth rate, yield, dry weight and biomass productivity were observed in 40 ppt salinity compared to other salinities. At 40 ppt, cell density was 85.33 x 104 cells. ml-1 as well as specific growth rate that was at 0.839 cells.day-1, with the highest average yield of C. vulgaris was observed on day 6 and day 8 (exponential to stationary phase) at 115, 3 x 104 cells.ml-1. Similarly, considerably higher dry weight at 40 ppt was observed at 0.038 g.L-1 with biomass productivity at 0.032 g.L-1.day-1 compared to other salinities tested However these results were not significantly different (p=0.7>0.05) from other salinities. This study suggested that 40 ppt can be used to culture C. vulgaris in 5 % concentration of water hyacinth organic medium to obtain better growth and higher biomass production.
