Abstract
Cultivation of green mussels (Perna viridis) using multilevel plastic baskets has been carried out in the waters of Salemo Island, Pangkep Regency, Indonesia. The research treatment was placement on the surface and bottom of the waters (depth of five meters) with different stocking densities. Measurement of oceanographic parameters was carried out three times during cultivation within 3 months, namely temperature, turbidity, TSS, salinity, pH, DO, TOM, nutrients and heavy metals as well as composition and abundance of plankton. Measurements of absolute growth and survival and quality of mussels were also carried out. The results showed that the conditions of oceanographic parameters and dynamics of plankton as food were in a condition that supported the life and growth of green mussels. Absolute growth of biomass and survival of green mussels did not differ between surface and bottom locations. There was an increase in the weight of green mussels of more than 100% of the initial weight with quality according to consumption standards.
