HUBUNGAN KOMUNITAS FITOPLANKTON DENGAN PRODUKTIVITAS UDANG VANAME (Litopenaeus vannamei) DI TAMBAK BIOCRETE
MetadataShow full item record
Management of phytoplankton is generally conducted by controlling the concentration of organic matter, fertilization and water exchange. Organic materials are from uneaten feed and excretion of shrimp. By using post facto method it was found four class of phytoplankton in biocrete pond at one cycle rearing of white shrimp (Litopenaeus vannamei). Population at early rearing period was dominated by Bacillariophyceae (50.4%; 13 species) and Cyanophyceae (42.41%; 1 species), followed by Dynophyceae (6.2%; 5 species) and Chlorophyceae (1.3%; 1 species). Increment in phytoplankton density was followed by increment in chlorophyll-a and oxygen from photosynthesis, and productivity was 2132 kg/pond.
