Hiroko Matsubara, (2011) Effects of different fish sizes, stocking densities and feeding rates of tilapia, Oreochromissp. Culture in chlorella sp. Production. Masters thesis, Universiti Malaysia Sabah.
To establish a suitable technique of Chlorella sp. production in tilapia culture tank, eight experiments were conducted. The recommendable stocking density (kg/m³) and feeding rate (%BW) of tilapia were investigated for different sizes of tilapia; 0.5 g (Super Small, 55), 9.1 g (Meddle, M), 46.0 g (Large, L) and 160.6 g (Extra large, LL) in body weight for Chlorella sp. production. All of experimental tilapia culture water was regulated to 10 ppt salinity by mixed freshwater and filtered seawater for the purpose of producing euryhaline rotifer, Brachionus spp. by using this Chlorella sp. In the 55 size tilapia culture, the optimum stocking densities and feeding rates for Chlorella production were 3 kg/m³ and 4 %BW, respectively. In the M size tilapia culture, the densities of Chlorella were not significant difference a month the stocking densities 2 to 6 kg/m³ and feeding rates 1 to 3 %BW. In the L size tilapia culture, the optimum stocking density and feeding rates for Chlorella production were 4 kg/m³ and feeding rate 1 %BW, respectively. In the LL size tilapia culture, the optimum stocking density and feeding rates for Chlorella production were 10 kg/m³ and 1 %BW, respectively. For the Chlorella production In tilapia culture, it was necessary to culture the tilapia under the optimum stocking densities and feeding rates according to the tilapia sizes. The M size tilapia culture with stocking density, 4 kg/m³ and feeding rates, 1 %BW is the most recommendable combination of tilapia rearing combination for Chlorella production in tilapia culture under 10 ppt.
