Putian cultivating loach is a highly efficient ecological breeding, generally more than 150-200 kg per mu. Wherever the water level is low and the silt layer is relatively thin, it can be used to raise oysters.
1. Putian transformation. Dig a circular fish ditch with a width of 2.5-3 meters and a depth of 1-1.2 meters around the plot, and let one fish slip in each corner or corner. Dig the mud to form a slope of 1 meter. The aboveground and above the slope should be covered with 30 or more white nylon nets or polyethylene nets. Both ends and joints should be buried in soil, or be inserted around. Plank and calcium plastic board (30cm into the mud), injection, drainage outlet to build a second network, the outside of the available polyethylene net, inside the metal mesh to prevent escape.
2, put into the species. Before stocking, the field should be drained, sun exposure for 3-4 days, and then 130 kg per mu. The next day, 250 kg of animal manure was applied per acre and dried for 4-5 days. After that, the water is planted and planted. After a week of planting, 10-15 grams of sturdy and sturdy oyster species of 80-100 kg will be stocked per acre.无 无 无 可选 可选 可选 可选 可选 可选 可选 可选 可选 可选 可选 可选 可选 无 无 无. Before the stocking, 20 grams of bleaching powder was used to disinfect Putian, and the quail was soaked with 3% saline for 3-5 minutes before stocking, so as to improve the survival rate of the loach.
3, daily management. Feed 2 times a day, feed 70% from 6:00 to 7:00 in the morning, and feed 30% at 1:00 in the afternoon. When the water temperature is 15°C, the daily dosage is 2% of the body weight, the water temperature rises, the feeding amount increases, and the highest feeding amount can reach 10% of the fish body weight. The water temperature is lower than 10 °C, noisy feeding or stop feeding, the first month after the release of the seed should be fed mixed cocoons and fried rice bran half of the mixed bait. Once a day, each feeding amount was 3-4% of the total weight of the alfalfa. After one month, the organic fertilizer mainly composed of animal fertilizer was applied once every 15 days, and the amount of topdressing was 100 kg per mu. At the same time feeding silkworm cocoon, rice bran, bean cake, vegetable cake, animal waste and other bait. It is better to fertilize and feed in the fish pit later in the collection period to facilitate centralized catching. The embankment facilities should be inspected frequently. If loopholes are found to be broken and collapsed, they should be immediately blocked and repaired to prevent predators such as birds, rats and snakes. Generally change the water once a month, apply a suitable amount of quicklime or bleach. Lotus roots management operates as usual.
