Environmental problems due to aquaculture occur along with the increase in aquaculture production. IMTA is one system used as a solution in dealing with environmental problems. The objective of this study was to analyze the growth performance, survival rate, and production of the main commodity (tilapia) and the supporting commodities (Peres, Lemeduk, and Depik) which are applied through the application of integrated multi-trophic aquaculture (IMTA) using floating net cages. This research was conducted at the Lukup Badak Fish Seed Center, Central Aceh from July to August 2020. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely: A (tilapia), B (tilapia and peres), C (tilapia and lemeduk), and D (tilapia and depik). ANOVA test results showed that the IMTA system had a significant effect on absolute length growth, absolute weight growth, specific growth rate (SGR), survival rate, and biomass production of tilapia (P0.05). The results showed that maintenance for 42 days produced the highest value in treatment B with the increase in absolute length growth (4.26cm±0.24); absolute weight growth (5.47g±0.45), specific daily growth rate (2.28%/day±0.13) and the highest tilapia biomass production (480g/0.5m2±19.25). The highest survival rate was found in treatment C (82.42%±2.28). It was concluded that the treatment using the IMTA system was better than without the IMTA system.Keywords:IMTAWater qualityGrowth performanceTrophic interactionBiomass production

Abstract. Kawan fish (Poropuntius tawarensis) is an endemic fish found in Danau Laut Tawar, Central Aceh, Indonesia. This species has been threatened by ecological partubation, unfrindly fishing practices and pollution. Cryopreservation is one of the ways to maintain the presence of these fish. Cryoprotectant (CP) is a critical material in the cryopreservation and DMSO is a common CP used in cryopreservation. Hence, the aim of the present study was to determine the optimum DMSO concentration for kawan fish sperm. The completely randomized design with 6 treatments and 3 replications were used in this study. The tested treatment was the difference of DMSO concentration, namely; 0, 3%, 6%, 9%; 12%, and 15% DMSO was combined with 5% egg yolk. The ratio of sperm to diluent is 1: 20. The cryotubes containing diluented sperm were evaporated at 5 cm from the surface of liquid nitrogen for 10 min, then stored in a liquid nitrogen container at -1960C for 2 weeks, then thawed and analyzed for the quality. The results showed that fresh sperm of kawan fish had motility of 48.67%, pH 7, milky white, with moderate consistency. The assessment of mass movements shows that the sperm has good quality. The ANOVA test showed that the addition of DMSO in diluents gavee significant effect on sperm motility, fertility and hatchability rates of fish eggs (P 0.05). The highest percentage of sperm motility and fertilization rates of fish eggs were found at concentration of 6%, respectively with the value of 46.67% and 45.67%, respectively. The highest percentage of hatching rate was also found in similar concentration of DMSO with the value of 19.33%. %. The DNA integrity test using the electrophoresis gel method showed that there was damage to DNA fish sperm after freezing, the the lower damage was found at 9% and 12% DMSO. It is concluded that the optimum concentration of DMSO for kawan fish sperm is at 6% of DMSO. Key words: kawan fish (Poropuntius tawarensis), cryopreservation, DMSO, DNA integrity Abstrak.

Depik Fish (Rasbora tawarensis) is an endemic fish species found in Tawar Lake, with a threatened status. Domestication efforts are being undertaken to conserve the Depik Fish population. This study aimed to analyze the effectiveness of different vitamins on the growth and survival of Depik Fish. The study was conducted at Balai Benih Ikan (BBI), Pegasing - Central Aceh Regency, from December 2021 to January 2022. A Complete Random Design (CRD) with four treatment levels and four replications was employed, including a control group and three experimental groups: 300 mg/kg feed of vitamin C, vitamin B complex, and Viterna Plus. The results of the Anova test indicate that the dosage of vitamin C, vitamin B complex, and Viterna Plus in commercial feed significantly influenced the absolute weight growth, absolute length growth, and specific growth rates of the Depik Fish (P<0.05). However, it did not have a significant effect on feed efficiency and survival. Duncan’s test revealed significant differences among the treatment groups, with the highest values observed in the application of Viterna Plus at a dosage of 300 mg/kg feed, which resulted in increased growth and survival of the Depik Fish. Therefore, the use of Viterna Plus in fish feed is recommended.

Tinfoil barb (Barbonymus schwanenfeldii) is freshwater fish found in Borneo, Java, and Sumatera including in Aceh Province waters. It is known as a native species in Indonesia, locally known as Tengadak or Lampan and this species is popular for consumption due to its taste. Tinfoil barb is targeted species of inland water for fisheries production. In recent years, the fish population has declined because of overexploitation and habitat degradation. Therefore, this study aimed to analyze the effects of temperature on Tinfoil barb (B. schwanenfeldii) eggs incubation using a funnel system. It was conducted at Balai Benih Ikan (BBI) Lukup Badak, Central Aceh Regency. The Completely Randomized Design was used as a statistical analysis method with four treatments and three replications at 22±1 oC, 25±1 oC, 28±1 oC, and 31±1 oC. Hatching was carried out using a funnel system with 100 grain/liter of eggs density for incubation. The parameters measured were hatching time and rate, egg yolk absorption time, the survival rate of the embryo, larvae abnormality, and water quality. The ANOVA test results showed that temperature significantly affected hatching time and rate, egg yolk absorption time, and larvae abnormality (P0.05). In contrast, the effect was insignificant on the survival rate of an embryo, with P0.05. It is concluded that the optimum temperatures for Tinfoil barb eggs incubation were about 25±1 oC–31±1 oC. A funnel system was more effective for incubation than the conventional system.Keywords:Tinfoil barbFishIncubationTemperatureFunnel System

Global biodiversity, especially fish, has experienced a decline, this occurs as a result of over-exploitation, the presence of introduced fish species and climate change. This condition makes researchers look for solutions to overcome these problems by using cryopreservation techniques. The main purpose of cryopreservation is to store, maintain, and ensure the survival of genetic material, so that using cryopreservation techniques can maintain the viability and function of gamete cells both immunologically, biologically and physiologically. The success of the cryopreservation technique has made this technique widely developed in various species of living organism including fish. This article summarizes and reviews the history of the development of cryopreservation of animal species with specific focus on fish.Keywords:CryopreservationHistoryDepikEndemic species

The artificial breeding method for depik fish Rasbora tawarensis was not available, and the extenders and its dilution ratio are the crucial factors in artificial breeding of fishes. Herein, we tested several common sperm extenders and its dilution ratio in the artificial breeding for depik fish. Two series of experiments were performed to find the best extender and its dilution ratio. In the first experiment, five types of extenders, namely: Ringer’s solution, physiological solution, coconut water, sugarcane water, and roomie water. The second experiment studied four dilution levels of sperm and extender (v/v), namely: 1: 20, 1: 30, 1: 40, and 1: 50. Every treatment was conducted in four replicates and experiments were conducted in series so that the best results in the first experiment were used in the second. The first experiment showed that Ringer’s is the best extender for depik sperm, and the second experiment revealed that Ringer’s at dilution ratio 1: 40 gave higher sperm motility, fertilization and hatching rates. Hence, the best formula for the dilution solution of depik sperm is Ringer’s at the dilution ratio of 1: 40, sperm: extender (v/v).
