Analisis parameter biologis (kelimpahan plankton, bod) pada budidaya udang windu (Penaeus monodon) bersama rumput laut (Gracillaria sp.) dan kerang hijau (Perna sp.) dengan sistem imta (Integrated Multitrophic Aquaculture)

Integrated Multi-throphic Aquaculture (IMTA) is a system in cultivation that prioritizes balance its maintenance. The IMTA method utilizes feed residues can be utilized by organism from the remaining biota at higher levels of trophic with lower levels. This study aims to analyze biological parameters different densities seaweed and green mussels best stocking for growth survival tiger shrimp. test animals used were PL 30 shrimp range sizes 0.03 0.08 grams / larvae. Stocking density 80 larvae m2. experimental complete randomized design factorial 9 treatments 4 replications. stock treatment 50, 100 150 while 30, 60, 90 grams. results showed highest rate was found A1B1 50 mussel RGR value 67.11% day SR 88.75%. Phytoplankton included 2 classes, namely Bacillariophyceae, Cyanophyceae. which dominates each Bacillariophyceae class. plankton abundance mussels. BOD values ranged 4.5 7.1 mg /l.
