Fish seedlings under the water of the pond, good water, and many benefits
According to the traditional breeding mode, the fish seedlings are divided into fertilizer submerged ponds and clear ponds. The so-called fertilizer submerged pond means that the pond water is treated with fertilizer in front of the fish pond. When the fish is in the pond, there is a large amount of palatable organisms for feeding. The advantage of this method is that a large number of fish fry eat food, not only improve physical fitness, but also save feed, the disadvantage is that the degree of water body fat is difficult to control, the body of water is easy to cause bubble disease. The so-called "underwater pond" means that the pool of water is not bred in front of the fish pond and the water is kept in a state of clean water. After the fish is fed to the pond, the fish is provided with palatable food by pouring soya milk. At the same time, the milk that has not been eaten can also achieve the purpose of water. The advantage of this method is that the fish eats artificial feed, and the water body is thin and the amount of feed is convenient for human control. The disadvantage is that the fish fry only ingest the soy milk particles, which is far less than the full nutrition of the raw fresh live bait. Once again, the key season for the fry “flowering†in the year is whether the fry in the bottom of the pond is good water or good water? Based on years of production experience, I think it is best to combine the two organically. About 15 days before the release of fry, the fish nursery ponds were completely cleaned and disinfected. After 5-7 days, the water was injected 0.8 meters deep. Then the fermented chicken manure was piled in the corners of the pond so that the water just flooded the chicken manure. The amount of chicken manure was 200 per mu. kg. After chicken droppings enter the water for 3-4 days, activate the activated limonin in the surface waters of the chicken excrement and the surrounding waters (risenase can be activated with 5% brown sugar water for 6-7 hours), and stir the dung to stimulate Lishengyuan and chicken manure particles are fully combined, and fish fry can be released after 3-4 days when the water color turns green. After the fry, the water color of the pond is not too green, and it is possible to spill the right amount (day by day) of soybean milk in the first few days, while closely observing the changes in the amount of "fish and fish" (ie, large clam-like aquatic animals that the fry can feed). When a group of "fish worms" appear in the body of water, they can stop feeding soy milk. At this stage, the chicken manure heap should also be frequently used to disperse the nutrient components of the chicken manure and feed it to the aquatic organisms and fry. When it was found that the fry was rarely on the water Ingestion of aquatic animals (indicating that aquatic animals in the water can no longer meet the feeding needs of the fry) can be fed at the feed station with broken full-priced compound feeds. When the fry starts feeding on broken full-priced compound feeds, it is necessary to stop the water and fertilizer cultivation. . If you miss the opportunity to use Shiji in front of the fish seedlings in the pond, you can also use the livestock manure that has been fermented and diluted with water and diluted with activated vitamins. Many years of production practice show that using this method to cultivate fish fry can save 50% of feed input, and the fry's constitution and survival rate are also higher than the traditional cultivation methods.
