Aquaculture Production

Currently, abrasion at the northern coastline of Central Java, Indonesia, is severe. One of the biggest abrasion area is in Kaliwlingi village (Brebes District), where 800 ha of brackish water ponds were submerged. Abrasion could wipe away or damage dykes on brackish water pond and the pond can no longer be used for aquaculture production. A 5 000 m2 of netting broken dyke of brackish water pond is used for semi–intensive cultivation of milkfish, tilapia, vanamae shrimp, green mussel and Gracilaria seaweed as an application of Integrated Multi Trophic Aquaculture (IMTA) concept. The aim of this study was to determine the aquaculture production in abraded dyke on brackish water pond by measuring the growth of milk fish, tilapia, vaname shrimp, green mussel and Gracilaria based on IMTA concept. The study was carried out from May to July 2015 at Kaliwlingi Village, Brebes district. The results showed Specific Growth Rate (SGR), i.e. milk fish 2.35 % d–1; tilapia 3.8 %·d–1 vanamae shrimp 3.75 % d–1; green mussel 2.8 % d–1 and Gracilaria 4.6 % d–1. Based on the result, the water quality is good and the availability of the natural food can support the growth of milkfish, tilapia, vanamae shrimp, green muscle and seaweed at broken dyke ponds with IMTA concept.

ABSTRACTIn applying traditional brackish water pond aquaculture of tiger shrimp (Penaeus monodon), plankton is one of water micro organisms that plays an important role as natural food and stability indicator of water or aquatic environment in which life and growth of aquatic organisms depend on water quality variables, both physical and chemical properties. This research objective was to find out the effects of dominant water variables on plankton abundance in brackish-water pond. The research was conducted in traditional brackish water ponds of tiger shrimp in Pasuruan Regency, East Java Province. The research was conducted through direct measurements in the field and also collection of plankton and water samples. Those were then analyzed in the laboratory. Better change to analysis used in this study was regression model analysis was based on the smallest square method. Dependent variables was plankton abundance and independent variables were the water quality variables such as temperature, dissolved oxygen, salinity, pH, total suspended solid (TSS), nitrite, nitrate, ammonia, phosphate, iron (Fe), and total organic matter (TOM). The result showed that range of plankton abundance was 20.0-6,360 individuals/L with average 401.3 individuals/L. There was a significant relationship between plankton abundance and TSS which negatively affected plankton abundance as much as 0.52 or 52%. Based on index values of average dominance, variety, and uniformity, the brackish water pond water or aquatic area in this study was categorized as moderately stable, where plankton genera were well distributed and there was no genus dominating other genus.

Indonesian shrimp cultures are threatened by vibriosis. Some traditional brackish water ponds remained along the north coast of Central Java after the disease outbreaks destroyed the shrimp culture. This study aimed to discover the Vibrio diversity associated with shrimp vibriosis in traditional brackish water ponds. An exploratory method with purposive sampling was used in this study. Twenty-four shrimps presumably infected with vibriosis were collected from two district regions on the north coast of Central Java in July–September 2018. The bacteria associated in shrimp vibriosis were isolated from the telson and inner part of the hepatopancreas with TCBS medium. Forty-one bacteria associated with shrimp vibriosis were obtained, and then repetitive-polymerase chain reaction (rep-PCR) was performed to obtain Vibrio strains. On the basis of rep-PCR results, five respresentative strains were selected for further study. The results of 16S rDNA sequence analysis showed that the JKP03, JKP05, JKP19, JKM01, and JKM06 isolates were closely related to Vibrio rotiferianus, Vibrio diabolicus, Vibrio parahaemolyticus, Vibrio alginolyticus, and Shewanella algae, respectively. Vibrio biodiversity in shrimp vibriosis was high. These results confirmed that traditional shrimp farming was susceptible to vibriosis. Therefore, control methods such as vaccines, probiotics, and immunostimulant formulas must be developed to prevent and control the outbreak of shrimp vibriosis in traditional brackish water pond.

Pinrang Regency is a center of brackish water pond aquaculture production in South Sulawesi Province in which some of brackish water pond farmers in this regency have adopted Good Aquaculture Practices (GAqP). A study was conducted to determine GAqP adoption level, to identify GAqP aspects required to be improved, and to determine the category of GAqP adoption level as the first step to maximize the GAqP adoption level in the brackish water ponds. Primary data were obtained from 76 respondents consisted of pond farmers who already have adopted and or obtained GAqP certificates. On the basis of the adoption level, the adoption level classification is carried out into three categories, namely low adopters, medium adopters, and high adopters. The results showed that the highest GAqP adoption levels in brackish water ponds were in food security (89.41%) and technical aspects (78.57%). The lowest GAqP adoption levels were in management (8.71%) and environmental aspects (0%). It was also reported that the GAqP adoption level in brackish water ponds varied from 40.58 to 67.01% with an average of 42.86% and was categorized as moderate adopters. Based on this study, management and environmental aspects were found to be the aspects that need serious attention to increase the GAqP adoption level in the brackish water ponds.

The present work aimed at determining the effects of the association between the periphyton-based system with the bioflocs-based system in the intensive culture of juvenile Nile tilapia (1.56 ± 0.07 g; 72 fish m-3), on variables of water quality, growth performance and effluent quality after 10 weeks. The experiment was arranged in a 2 x 2 factorial randomized block design with four treatments and five repetitions each. The factors tested were the following: ‘underwater structure’ (absence and presence) and ‘adjustment of the C: N ratio of water’ (no and yes). The final fish body weight, specific growth rate and yield were higher (p < 0.05) in the C: N-adjusted tanks. The presence of submerged structures in the tanks had no significant influence on those same variables. It was concluded that the periphyton-based system is not indicated for intensive farming of Nile tilapia, in which there is a high allowance of artificial feed to fish.

Catfish (Clarias sp.) is a freshwater fish that is widely cultivated because it is a leading commodity. Increased production of catfish resulted in extra area of cultivated land and water use. The technology suitable to be applied is aquaponic system. In addition to saving land and water use, Aquaponic is also improving business efficiency through the utilization of nutrients from food remains and fish metabolism. Water quality is an important factor for the success of cultivation. Maintenance catfish with the addition of probiotics in aquaponic system can be a solution for maintaining water quality, because it contains bacteria that can increase nitrite to nitrate changes that can be utilized for growth of plants and do not poison the fish. The purpose of this study was to determine the effect of different probiotics in the aquaponic system towards growth rate and survival rate of catfish. The method that used in this research is experimental with completely randomized design (four  treat and five repeated) are P0 (control), P1 (probiotic A), P2 (probiotic B) and P3 (probiotic C). Analysis of data processed using Analysis of Variance. If there are significant differences then continued Duncan's Multiple Range Test. The results showed that the giving of probiotics in the aquaponic system is significantly different (p <0.05). The final conclusion is that the addition of probiotics in  aquaponic system affect the growth rate and survival rate of catfish. The highest specific growth rate (0.025%/ day) and the highest survival rate (77.8%) contained in the P2 treatment. The lowest specific growth rate (0.019% /day) and the lowest survival rate (64.4%) contained in P0 treatment (control). Keywords : Aquaponic, Catfish, Probiotic, Growth Rate, Survival Rate, Clarias sp.

Growth inhibition of chromium (Cr), cadmium (Cd) and lead (Pb) to fresh water microalga Chlorella vulgaris (C. vulgaris) FACHB-8 was examined. These results demonstrated that the concentration level (EC50 value) of three heavy metals (Cr, Cd and Pb) could be utilized as an indicator for evaluating the toxicities of Cr, Cd and Pb for microalga growth. The EC50 values of Cr for C. vulgaris were 0.22, 0.07 and 0.04 mg/L at 24, 48 and 72 h based on Algorithm 2 (%Ir, percent inhibition in average specific growth rate), respectively. The EC50 values of Cd for C. vulgaris were 2.76, 1.08 and 0.93 mg/L at 24, 48 and 72 h based on Algorithm 2, respectively. The EC50 values of Pb for C. vulgaris were 73.21, 65.02 and 48.38 mg/L at 24, 48 and 72 h based on Algorithm 2, respectively. The results laid a good foundation for the application of C. vulgaris in the water quality monitoring.
