he characteristics of Guangdong tilapia:
Guangdong tilapia with a mixed diet, hypoxia tolerance, tolerance to low temperature is not strong, propagation:
1, a mixed diet: Guangdong tilapia is plant-based omnivorous fish. Guangdong tilapia ponds, gut contents mostly organic debris and other plant feed (such as water grass, commercial feed and so on), followed by phytoplankton, zooplankton and small benthic animals.
2, resistant to hypoxia: Guangdong tilapia hypoxia resistant ability is very strong, asphyxia point was 0, 07, 0, 23 mg / L, the oxygen in the water 1 and 6 mg / L, Guangdong tilapia can still live and breed. The oxygen in the water more than 3 mg / L, growth was not affected.
3, not resistant to low temperature: the survival temperature range Guangdong tilapia was 15 - 35 ℃. When the water temperature is below 15 ℃, tilapia dormant. Tilapia highest critical temperature of about 40 DEG C －41 ℃, the optimum growth temperature was 28 ℃ - 32 ℃, Guangdong tilapia breeding temperature at 20 ℃.
4, breeding strong: Guangdong tilapia early sexual maturation, spawning cycle short, oral incubation juvenile, reproductive condition requirements is not high, the static water area of natural reproduction. Tilapia 6 months reached sexual maturity, weight 200 grams of female fecundity number during breeding in the 1000 - 1500 eggs. Males have marriage, color beautiful, abdominal anal and urogenital hole two, squeezing the abdomen white semen, females abdomen with 3 holes, i.e. the anus and genital pore and urinary pore. The water temperature of 18 ℃ - 32 ℃, mature males have "dig nest" ability, mature females nest matching, output of mature eggs and immediately be contained in the mouth, make ovum fertilization, zygote development in females in the oral cavity, the water temperature 25 ℃ - 30 4~5 days hatched juveniles. The mother left the juvenile to yolk sac disappeared and has a certain capacity.
