Abstract

The increase in Vannamei shrimp farming is closely related to an increase in the demand for shrimp feed. At present there are many technological developments in cultivating natural feed. The natural feed here refers to plankton which can be used as natural food for every organism of larvae in waters. Conditions in water will affect the distribution pattern of phytoplankton either horizontally or vertically. As a result, it affects the abundance of phytoplankton and subsequently also affects the value of the main productivity. The purpose of study is to find out the cultivation process and to find out the types of plankton that exist in Vannamei shrimp farming ponds. Plankton observations were carried out directly with the help of a microscope and haemocytometer, while the measurement of water quality using each instrument had been prepared for each parameter. The results of plankton observations found species of Chaetoceros sp., Oocystis sp., Oscillatoria sp. and Cyclotella sp. while the water quality measurements obtained temperature (29-31°C); DO during the day (7.6-9.5 ppm) and at night (4.0-4.6 ppm); pH in the morning (7.8-8, 5) and daylight (8.1-9.0); and salinity 26-27 ppt. The application of probiotics used carbon sources derived from molasses and katul.
