Study of trophic interactions of green mussels (Perna viridis) as bioremediation of waste for cultivation of windu shrimp (Penaeus monodon) in Gampong Alue Naga, Banda Aceh: application of IMTA system (Integrated Multi-Trophic Aquaculture)

Abstract Residual organic matter from the cultivation of Windu Shrimp ( Penaeus monodon ) can cause a decrease in quality cultured water. This study aims to examine trophic interactions and Green mussels Perna viridis polyculture system including observing growth performance, survival rate bioremediation level green mussels. research was conducted April – September 2022 Gampong Alue Naga, Banda Aceh. Sample biota (PL20) with an average length 1.2 cm, obtained nature shell size range 3 cm 5 cm. Research on species composition per container volume used completely randomized design method 4 treatment levels replications. The treatments this were differences stocking density A (0 ind/m 2 ), B (20 C (40 D (60 ). In study, number windu stocked same, namely 60 fish/container 1x1 meter. results showed that difference had significant effect (p<0.05) absolute shrimp but no weight daily (p>0.05). (SGR) ranges 10.54% - 11.98%. lowest value found B, which 26.11±10.04 highest is 73.33±26.6. best 40 . mussel filtration ranged 0.6 1.7 L/day. Application multispecies (polyculture) better than monoculture based performance
