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.
Soybean milk production Soybeans are soaked in warm water of 25°C-35°C for 5 hours to 8 hours before refining. When refining, add soybeans and water at the same time. Generally, 10 kg to 20 kg of water are used per kilogram of soybean. Can also be soaked in soybean cake after refining. The soaking time of the bean cake is 5 hours to 6 hours, and 10 kg to 12 kg per kilogram of water are used for refining.
The method of pouring pulp is to prolong the suspension time of soy milk particles in water and improve the utilization of soy milk. It is fed 3 times to 5 times a day, and the entire pool should be spilled. The most soymilk fat fry is effective to pile up the four corners of the fry
Grass is tender and then the soymilk is splashed around the grass so that the young fry can eat stoutly because they like intensive. 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 amount of liquid-bearing seedlings was fed on an average of 667 square meters per day to 3 kg-4 kg of soya milk; after one week, it was increased to 5 kg-6 kg, and the dosage was adjusted according to the water conditions. The color of water should be live, fat, tender and cool. In general, 10,000 species of fish are raised, and soybeans need 7 kg to 8 kg. In addition, rearing grass carp or blue-fish fry, 10 minutes after the fish ponds up to 10 centimeters, the food intake is larger than other negative seedlings. At this time, in addition to pouring soy milk, it is best to use thicker bean paste, bean cake, etc. Stacked in shallow water around the pond for feeding.
Slurry time is generally from 8 am to 5 pm. 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 too late, you can't eat before dark, and the milk in the water can also cause negative oxygen in the pool. If the weather is hot and you want to make a thunderstorm or a rainstorm, be sure to feed less or stop feeding.
