Abstract

North African catfish (Clarias gariepinus) is a food ingredient with high protein content, so it is needed as a source of nutrition. In intensive catfish farming activities, there are constraints on water quality. The high stocking density causes a high value of ammonia. In addition, Nitrobacter, in an intensive aquaculture system, is expected to improve water quality. Especially ammonia, so that it can increase the growth and survival of fish. This study aims to determine the effect of Nitrobacter with different doses on the maintenance of North African catfish. This research was conducted from September to October 2022 at the Aquaculture Environmental Quality Laboratory, Department of Aquaculture, Faculty of Fisheries and Marine, Universitas Riau, Pekanbaru. The research method used in this study was a completely randomized design (CRD) 1 factor with five treatment levels and three replications. The treatment in this research is P0: Dosage Nitrobacter 0 mL/L, P1: Dosage Nitrobacter 0.5 mL/L, P2: 1 mL/L, P3: 1.5 mL/L, and P4: 2 mL/L. Giving Nitrobacter is done once a week according to the dose of each treatment. This research was conducted for 30 days. The research results show that dosing Nitrobacter has different effects on reducing ammonia levels and maintaining North African catfish. The best treatment was P3 1.5 mL/L with the smallest ammonia content of 0.0403 mg/L. a specific growth rate of 0.98%. An absolute growth rate of 0.76 g, an absolute length of 1.06 cm, and a survival rate of 81.4%. The value of water quality during the research was 29-300C, pH 6.5-7.0, and DO 2.9-3.3 mg/L. The value of water quality during the study was good enough to support the survival of North African catfish.

Abstract

The demand for ornamental fish is currently increasing while the availability in nature is decreasing due to overfishing. Clownfish (Amphiprion ocellaris) is a type of marine ornamental fish that is widely kept in aquariums, but the problem is the rapid decline in water quality due to the activity of these fish. The recirculation system is one way that can be used in water quality management. The study aimed to analyze the type of filter used to stabilize seawater quality in clownfish (rearing containers. This research was conducted from January to April 2021 at the Research Centre of Sibolga Fisheries College. The method used was an experimental method using a one-factor Completely Randomized Design (CRD) with four treatment levels and three replications. The treatments in this study were P0 (unfiltered), P1 (cotton filter), P2 (fiber filter), and P3 (activated charcoal filter). The fish used was 2 – 3 cm in size, kept in an aquarium measuring 60x40x40cm with a stocking density of 2 fish/L of water and fed tubifex 2 times a day, at 08.00 and 18.00 WIB as much as 5% of their body weight. Parameters measured were temperature, pH, DO, salinity, ammonia, and phosphate, abundance of bacteria, phytoplankton, and survival of clownfish. Water quality measurements are carried out every 7 days. The results obtained from the improvement and analysis of water quality for the cultivation of clownfish in the recirculation system provides an influence on water quality in the rearing container. The results obtained were temperature 27.9–28.0 0C, pH 8.3–8.4, DO 7.5–8.0 mg/L, salinity 33-34 ppt, ammonia 0.04–0.06 mg/L, phosphate 0.47–0.48 mg/L and bacterial abundance 2.35x104 CFU/mL with a survival rate of 95.55%.

Abstract

Microalgae has an important role in the world of fisheries, because the availability of microalgae is needed as a natural feed in the hatchery business of fish and shrimp. One type of microalgae that is potential to be developed as a natural feed is Dunaliella salina. Factors that influence affect the density and carotenoids of D. salina is the intensity of light because it has an important role in the process of photosynthesis. This study aims to get the best light intensity in increasing the density and content of D. salina carotenoids. This research was conducted on 12-21 May 2019. Located in the Natural Feed Laboratory, Center for Brackish Aquaculture Fisheries (BBPBAP) Jepara. The research method used was a Completely Randomized Design with 4 treatments giving different light intensities namely P1 (2,500 lux), P2 (3,500 lux), P3 (4,500 lux) and P4 (5,500 lux) with 3 replications. Growth was observed for 10 days by calculating daily density and carotenoid content on the 6th day. The results showed that different light intensities affected the density and content of D. salina carotenoids. The highest density and carotenoid content was found in the light intensity of 5,500 lux with a density of 637.87 x 10 4 cells /ml and the carotenoid content of 1.45 µg /ml.
