Soymilk is rich in nutrients and has a high protein content, which can meet the nutritional needs of fry and allow fish to grow quickly. In addition, the soy milk that can't be eaten by the fry falls into the water, the water quality is easy to be fattened and the fertilizer is stable, the quantity of plankton is more, and fish diseases and predators are less.
Making milk
Soybeans are soaked in warm water at 25-35°C for 5-8 hours before refining. Soybean and water should be added at the same time when refining, generally 10-20 kg of water per kilogram of soybean. Can also be soaked in soybean cake after refining. The soaking time of the bean cake is 5-6 hours, and 10-12 kilograms of water per kilogram for the refining.
Pouring method
In order to prolong the suspension time of soy milk particles in water and increase the utilization rate of soymilk, feed 3-5 times a day and the entire pool should be spilled. It is best to pile some tender green grass on the four corners of the fry pool, and then spill the milk around the grass. Grass and herring like to concentrate on activities in the shallow water near the pool, so the pool of grass and green turtle ponds should splash more milk.
The number of batter
During the seedling period, 667 kilograms of soybean milk was fed on an average of 667 square meters per day; after 1 week, it was increased to 5-6 kilograms, and the dosage was flexibly adjusted according to the water conditions. The color of water should be live, fat, tender and cool. Generally cultivating 10,000 species of fish need 7-8 kilograms of soybeans. In addition, rearing grass carp or bluefish seedlings, when the fish 10 days after entering the pool up to 10 centimeters, when the food intake is greater than other fry, then in addition to pouring milk, it is best to use thicker bean paste, bean cake, etc. In the shallow water around the pond for them to feed.
Slurry time
It is usually from 8 a.m. to 5 p.m. Early water temperature is low, oxygen content is low, and fry are eating less. Especially when the fish floats, the slurry will increase the lack of oxygen floating head. If you feed it too late, you can't eat it before dark, and the decomposition of soybean milk in water can also cause oxygen deficiency in the fish pond. If the weather is hot and you want to make a thunderstorm or a rainstorm, be sure to feed less or stop feeding.
