Techniques Tanaka pond fish

Dig the pond in the field, put the fish in the pond and grow rice in the field. During the rice growth and development, let the fish in the pond swim to the fields and eat the weeds, worms, aquatic animals, and water in the fields. Organic nutrients and paddy rice that have fallen during flowering, the fish not only grow fast and grow quickly, but also have fast weight gain, fast fattening, no pollution, clean fish, strong fruit, strong flavour, and good meat quality. Moreover, rice suffers from diseases and pests. Good growth, strong, high yield, excellent quality. The technical points of Tianzhongtang fish farming are as follows:

Dig the pond. Tianzhongtang fish farming area accounted for one-third of the pond, field area accounts for two-thirds of the most appropriate. Choose to dig the pond in the middle of the field, about 1.5 to 2 meters deep. The pond base is 50-60 cm wide and 30-40 cm high, leaving 3 to 4 outlets, each 20 to 30 cm deep and wide. At the same time, a 30-40 cm wide path leading to Tianbian can be built. The pond should be dug about one and a half months before the “Ching Ming”.

Water storage. In the first half of the Qingming, there was a flood of pond water. If the pond water is a clean river, landscape, spring or groundwater. After the pond is filled with water, 0.5 to 1 kg of dry and pure plant ash is applied per square meter of water to disinfect the pond water and cultivate aquatic organisms, and fertilize the pond water. Afterwards, it is necessary to pay attention to the inspection of the pond water, and when it is found that the pond water is reduced, supplement it in time to maintain the depth of the pond water.

Put the fish. During the "Ching Ming - Gu Yu" period, when the temperature rises, fish can be released. Generally, every 100 square meters of fish ponds will have 100 grass carp fish, 150 catfish, squid, and squid, and 500 fishes of pond horn fish. The weight of fish fry put is about 30 to 50 grams. At the same time, 15 to 20 snail species weighing 25 to 30 grams per square meter are placed, allowing the snail species to breed at the bottom of the pond, and to do a scavenger to clean the water. When the fish is cast in the snail, first let the fry and the snails soak in the 1000-fold vitamin C aqueous solution or the 1000-times baking soda aqueous solution for 10-15 minutes to sterilize to kill the various pathogens that are excreted in the fry and snails. Then feed into the pond.

Feeding. After 5 to 10 days after the fish is released, it is necessary to feed and feed some plant natural feed such as grass and peanut cake powder, corn flour and soybean powder. Let grass carp eat grass, carp, carp, carp eat peanut cake powder, corn flour, soybean powder, pond angle fish, snail grazing fish, carp, carp, squid excrement of manure, generally every 2 to 3 days once, each Every 10 to 15 kilograms of green grass on every 200 square meters of water surface, peanut cake flour or corn flour or soybean powder 6 to 8 kilograms, evenly placed on the surface of the water, so that fish can freely feed.

Field. About 15 to 20 days after the early rice planting, when the seedlings are about 30 to 40 cm high, they can open the water outlet, let the fish in the pond swim out of the fields, eat the weeds in the fields, and eat the aquatic animals in the fields and each Insects, eating organic nutrients in the water. When rice blooms, there are rice flowers scattered on the water for feeding. During this period, basically no feeding is required. If you need to spray pesticides or spread fertilizers, you have to rush fish back to the pond and block the outlet before it can poison fish. After the early rice is harvested, it is necessary to block the outlet and allow the fish to move in the pond. At this time, feeds such as grass and peanut cake powder, corn flour or soybean powder should be properly put in. When the late rice seedlings are about to be sealed, open the outlet again. , Let the fish out of the field activities, has been put until the late rice harvest before the field dry? 笫 谟昙 谟昙 谟昙 谟昙 笆 笆 笆 笆 笆 笆 chat? 獗 獗 獗 愀匣靥 愀匣靥 愀匣靥 愀匣靥 愀匣靥 chat? ?/P>

Make up water. In the rearing process, if the pond water is reduced, supplement it in time, especially in the dry season, pay attention to keep the pond water more than 1.5 meters deep. When replenishing water, if the field is clean, fill it directly from the field. If there is a lack of water in the fields, or if the fields are polluted, such as spraying pesticides, applying fertilizers, etc., they must be filled from rivers, springs, mountains or groundwater.

Disease prevention and insecticide. Tianzhongtang fish culture, pond water, and field water are all relatively clean. Fish is rarely sick, but after fish swims out of the fields, they are vulnerable to parasites such as trichodiae, tongue beetle, and ciliate. Therefore, we should always put some fresh pine needles with a branch in the pond and put some dry and pure plant ash in the field to kill various parasites that are extinct in the water and kill the bacteria in the water. Freedom from harm.

Capture. Fish reared during the “Qingming ~ Guyu” period can be caught before and after “Chongyang”. At this time, grass carp, carp, carp, and carp can each weigh about 2 to 3 kilograms each, and Tongjiao Fish weigh 250 to 300 pounds each. Grams, summer breeding snails weigh 20 to 25 grams each. Per 200 square meters of fish ponds can be harvested more than 1,000 kilograms of carp, grass carp, carp, eel, pond angle more than 150 kilograms of fish, snail more than 500 kilograms. If you do not capture before and after “Chongyang,” keep the pond water depth 1.5 to 2 meters before catching it before the “winter solstice”. At that time, the fish and snails are heavier and more fat, and the meat quality is better. The yield is also significantly increased because the winter fish and snail are more Easy fattening.
