Abstract

This research was conducted at the Center for Brackish Water Aquaculture Situbondo on February to April 2013. The research material is the development of the egg mouse grouper (Cromileptes altivelis) to the size of the seed. Humpback grouper hatchery activities undertaken in Situbondo Brackish Water Aquaculture Centres covering, container preparation, maintenance of the parent, the parent spawning, handlers egg, larva, natural food culture, water quality management and harvest seeds. Spawning parent process carried out at the bright moon and new moon after the management maintained a predetermined feed. Observations eggs done from the early morning (eggs age ± 4 hours) to hatch (± 28 hours) by using a light microscope with a magnification of 10 x10. Larval rearing is to obtain seeds produced optimally usual during 45-55 days. The seeds that will harvest measuring 2 hinga 5 cm and ready to send to consumers first fasted for between 12-24 hours with the aim of reducing expenditure stool (feces) during transport seeds.

Abstract

The purpose of this study is to know the techniques for natural food culture (Chlorella sp, Rotifera sp) mass scale and the management of natural feeding larvae Cantang grouper (Epinephelus sp) in Situbondo BPBAP which was held from 04 February to 04 May 2015. Fertilizer use is: UREA = 400 gr, ZA = 300 gr and TSP / SP-36 = 200 gr. After fertilization, tubs filled inoculant of Chlorella sp. as much as 20% streamed using 1-inch hose and pump with a capacity of 450 V until evenly distributed (marked in green on the entire surface of a body culture). Harvesting Chlorella sp. performed after the maintenance period 7 -8 days. Rotifer mass culture is done in an open bath with a capacity of 5 tonnes with the installation of oxygen (aeration), inlet and outlet pipes are equipped with stop valves. Before use, bath cleaned first, then filled with sea water as much as 3 tons and filled Chlorella sp 1 ton gradually. Harvesting is done if it had been passed through a maintenance period 4-5 days using planktonet measuring 300 microns. Distribution of Chlorella sp. Reviewed grouper larvae Cantang since D2 - D30 with a density of 15,000-20,000 cells / cc or ½ ton to 1 ton. Provision of Chlorella sp. conducted in the morning is 07.00 pm. While Rotifers sp. given the grouper larvae Cantang since D2 - D30 gradually namely on D2 = 2-5 ind / ml. While on D3 - D30 = 5-10 ind / ml. Giving Rotifers sp.dilakukan at 08.00 am.
