Tilapia is not salmon.

Tilapia is a kind of economic fish, reproduction speed, and the taste and common fish is almost the same, it is easy to get tired of eating, so the price of tilapia has been very cheap, in the coastal areas, and even can be sold to 1, 2 yuan a catty, but tilapia is rich in protein, vitamins, minerals, consumption can be added to the body of the body's energy, the general population can be eaten.

Adult fish farming

Generally take the form of monoculture and mixed farming. Monoculture tilapia, in a pond with a water depth of 1 meter, put 3000-5000 fish species of 3 cm size per mu, the yield can reach 300-400 kg. Mixed culture can be divided into two forms of tilapia as the main fish and tilapia as the main domestic fish and then ride the tilapia.

Tilapia-based adult fish pond stocked with 2,500 tilapia species of 3-5 centimeters, raised to specifications up to 180-200 grams / tail. Tilapia breeding in ponds dominated by domestic fish can increase production by 10%-20%. Adult tilapia mainly feeds on plankton and organic debris, so the water quality should be fertile whether it is monoculture or mixed culture mainly with domestic fish.

Cultivate the water quality through fertilization, so that the water body is rich in biological bait. Generally, 100-150 kilograms of manure or 200-300 kilograms of green manure are applied per mu every week. During the feeding period, the method of regular water injection or water change is adopted to promote the photosynthesis of phytoplankton, so that the water body maintains sufficient bath oxygen, which is conducive to the growth and feeding of tilapia.
