Abstract

ABSTRACTCultivation of green mussels (Perna viridis) using multilevel plastic baskets has been carried out in the waters of Salemo Island, Pangkep Regency, Indonesia. The purpose of this study was to determine the oceanographic parameters that affect mussel cultivation at different water depths. The research treatment was placement on the surface and bottom of the waters (five meters deep) with different stocking densities. Green mussel cultivation is carried out for 4 months, namely May, June, July and August. Measurement of oceanographic parameters was carried out every month during green mussel cultivation, in situ, namely temperature, turbidity, salinity, pH, DO and those analyzed in the laboratory, namely TSS, TOM, Nitrate, Phosphate and the composition and abundance of plankton. Growth measurements of green mussels were also carried out, namely absolute weight and survival (SR). The results showed that the condition of oceanographic parameters differed between the surface and bottom waters, especially the parameters of TSS, turbidity, TOM, nutrients and plankton abundance. This situation is related to the absolute growth value and SR of mussels at different stocking densities and depths.Keywords: Oceanographic, green mussels, multilevel baskets, absolute growth, Salemo

印度尼西亚邦吉普省萨莱莫岛水域采用多层塑料篮法养殖格伦贻贝（Perna viridis）的海洋学条件

ABSTRACTC 使用多层塑料筐在印度尼西亚 Pangkep 行政区 Salemo 岛水域养殖绿贻贝（Perna viridis）。这项研究的目的是确定影响不同水深贻贝养殖的海洋学参数。研究处理方法是在水面和水底（5 米深）投放不同密度的贻贝。绿贻贝养殖为期 4 个月，即 5 月、6 月、7 月和 8 月。在绿贻贝养殖期间，每个月都在原地测量海洋学参数，即温度、浊度、盐度、pH 值、溶解氧，以及在实验室分析的参数，即 TSS、TOM、硝酸盐、磷酸盐以及浮游生物的组成和丰度。还对绿贻贝的生长情况进行了测量，即绝对重量和存活率（SR）。结果表明，表层水和底层水的海洋学参数条件不同，特别是总悬浮固体、浊度、总有机碳、营养物质和浮游生物丰度参数。这种情况与青口在不同放养密度和深度下的绝对生长值和SR有关：海洋学、绿贻贝、多层篮、绝对生长、Salemo
