Abstract
This research was aimed to discover the growth of converted Larasati tilapia (Oreochromis niloticus Linnaeus, 1758) using bioflocs system on its farming, the dynamics of its water quality, and the fish health condition. Bioflocs is the utilization of floc-forming bacteria (flocs forming bacteria) for sewage treatment. Waste mentioned in fish farming is particularly faeces and feed residue. This research took place at Laboratory of Aquaculture, Fisheries Department, Faculty of Fisheries and Marine Science of Diponegoro University. It started from May 2013 to August 2013. The design of the research was exploratory. The data of Larasati tilapia are from Janti, weighted 93.32 g or 200 fish per m3. The fiber tank with 2 m3 capacity is prepared for the bioflocs technique. The result shows that the growth of Larasati tilapia with bioflocs system on its farming is better than with the conventional system. The survival rate SR reaches 90 % and food corvertion ratio FRC reaches 0.82. The water quality shows that there is oxygen dynamics around 4 mg · L–1 to 5 mg · L–1 and Amonia around 0.01 mg · L–1 to 0.015 mg · L–1. Based on the cell concentration and the blood chemistry, it can be concluded that the L. tilapia with bioflocs system on its farming is healthy.
Highlights
Nile tilapia is popular fish and its production is very important for aquaculture industry
The research showed that Larasati tilapia with bioflocs technology on its farming was growth (Fig. 2.)
Tave (1999) stated that the fish growth for productivity development of aquaculture can be done with selection process
Summary
Nile tilapia is popular fish and its production is very important for aquaculture industry. Based on Avnimelech (2013), nile tilapia which belongs to tilapia is one of the ideal fish to be farmed using bioflocs technology. It is because nile tilapia is omnivore, which eats both natural and artificial feed, and they consume the organic waste (Farouq, 2011). The research of finding new species is done to fulfill the demand of the high quality nile tilapia seed It was reported by the local aquaculture research center in Janti area that Larasati tilapia is a high quality nile tilapia from the crossbreeding of female GIFT strain (GG) with Male Singapore strain (SS), third generation (F3) (Satker PBIAT Janti, 2011)
