Tilapia wholesale

Tilapia (O'Neill fish) is the parent of the blue tilapia and Nile tilapia as female hybridization, obtained filial generation. Tilapia have shape characteristics, and high back, thick body, small head, shaped like sea bream, body color elegant glossy. Tilapia survival water temperature is 12-39 ℃, the lowest critical temperature is 7 ℃ (common tilapia is 10 ℃), the highest critical temperature of 40 ℃, optimum growth temperature of 24 ~ 35 ℃, short time can be resistant the lowest temperature of 4 ℃, the maximum temperature of 42 ℃, the water temperature is lowered to below 10 ℃ stop feeding growth, the temperature dropped to below 4 ℃ will freeze to death. . Survival PH range 5-10, the optimum range PH7-8.5. Asia euryhaline, both live in freshwater, but also live in brackish water, salinity 8 ‰ less good growth. Resistance to hypoxia, low dissolved oxygen in the fertilizer can grow normally. GIFT is a modified rear tilapia genetic traits (Genetic Improvement of Farmed Tilapia), the English name of the word acronym GIFT, Chinese law referred to as sound Yoshitomi. The fish is since 1993 the use of Nile tilapia strains four Asian and four African strains of a wide range of germplasm in the Philippines bred new lines. This excellent breeding lines, is WorldFish Center (formerly the International Aquatic Biological Resources Management, ICLARM) and Norway, the Philippines, research institutes genetic improvement programs implemented in collaboration tilapia (GIFT program) the results achieved, are aquatic animals Breeding is another successful example.
