good night hive friends, hopefully in good health always, amen.
Chlorella sp. is a natural food for zooplankton and grouper larvae.
The presence of natural food for microalgae Chlorella sp. can also minimize the amount of production costs in fish farming because the feed used is low-priced feed and has a high level of protein content so that it can promote higher growth in these fish. Chlorella sp. culture technique. which starts from the preparation of the tub. Before entering Chlorella into the tub, it was done before the pool, filling water, aeration was carried out for 24 hours. After the plankton can be put into the tub and done in the morning to get enough sunlight. Furthermore, fertilization was carried out with Urea, TSP and ZA fertilizers at a dose of 200gr/l, 100 gr/l, and 60 gr/l. Water quality management, water sources used in natural feed culture tanks are derived from direct seawater. Water quality parameters measured every day in the morning are temperature, pH, salinity. Optimum temperature for Chlorella sp. between 25-300 C, pH 4.5–9.3 and salinity 25-35‰. Prevention of contamination of Chlorella sp. This is done by presenting chlorine on the tools and materials to be used. Harvesting is carried out in two ways, namely, the first is deposited and the second is harvested in liquid form.
Thank you, hopefully useful 😊🙏
