Abstract

The release of organic waste into the waters due to the Eel (Anguilla sp.) rearing activity will cause eutrophication. Efforts to reduce organic waste can be done by using local mussel (Pilsbryoconcha exilis) because it has biofiltration capabilities. The purpose of this study was to determine the ability of local mussels in reducing organic waste. The research design used in this study was a randomized block design (RBD), with treatment in the form of differences in waste concentration (50% and 100%), while the group was in the form of differences in the size of the gravestone (small, medium, and large). The results showed that mussel was able to reduce organic matter, the effective time of local mussel (P. exilis) to reduce organic waste from the cultivation of eel (Anguilla sp.) Was in the first 6 days. The most effective treatment is the use of 100% waste concentration and small mussel. This treatment was able to reduce COD values ​​by 66.1 mg/L (28%), turbidity by 187.2 NTU (16%), TSS by 134 mg/L (36%), and ammonia by 0.004 mg/L (24%), and increased biomass by 7.21 grams (3%).

Abstract

Eel (Anguilla bicolor bicolor) rearing activities that develop in Indonesia generally still use a large volume of water. The application of a recirculation system reduces water requirements and at a small volume of water, the load on the container to accommodate water becomes lighter so that several containers can be arranged vertically. This study aims to determine the best water volume in eel rearing with a recirculation system on production performance. This study used a completely randomized design with four treatments and three replications. The treatments, namely the difference in the volume of water (VA) used in the maintenance container, included VA 2.5 L (A), VA 3.5 L (B), VA 4.8 L (C) and VA 5.8 L (D). Eels were reared for 60 days in an aquaverticulture system with a stocking density of 10 fish per container. The test parameters in this study included survival rate (SR), specific growth rate (LPS), absolute weight growth (PBM) and feed conversion (FCR) and coefficient of final weight diversity (KKb). Other parameters analyzed include water and land use analysis. The results showed that aquaverticulture with multilevel containers on eel produced the best water volume of 5.8 L with high production performance (100% survival, specific growth rate 1.60%/day). The volume of water needed to produce 1 kg of eel for 1 year is 27.69 liters and the productivity of aquaculture land is 86.14 kg/m2. During the COVID-19 pandemic, this system design has been applied on a laboratory scale, but has not been applied commercially in the community.
