Splash is an industry term for hatching a film that can swim fry. Seasoning time for water bloom in Sichuan is generally from the end of March to August, and water in Guangdong enters Sichuan at the end of March. April is the peak and it basically ends at the end of April. Sichuan Shuihua began to emerge in mid-April, and the technically strong broodstock kept a large amount of seedlings in the water in August. Normally, in order to gain time, the seedling field will have a large number of water splashes in Guangdong, mainly grass carp and white peony. The first step: The important work before the water splash is the clear pond. The clear pond is the first guarantee of the high survival rate of the spray. Kill parasite eggs, large harmful aquatic insects, harmful bacteria, and miscellaneous fish in the sludge. The best way to clear the pond, winter sun pond, the best clear pond medicine recommended lime. With regard to the amount of quicklime, one hundred kilograms of water can be used for clearing one mu of clear water. The second step: Into the water, the inlet must be filtered with a dense mesh cloth, otherwise the clear pond kills the pest, and the water is brought in again. The influx of water emphasizes that the time for entering the water should not be too early, and if the incoming water is too early, the water will age and grow large aquatic insects. For example: rotifers, cladocera, copepods, duration is the key to livelihood and high-speed growth. The fact that the quantity is long lasting can greatly save labor and it is no longer necessary to boil the egg yolk to beat the Soybean milk every day. The third step: fertilization, this is an important work to cultivate the fish's open bait. Xintang fertilizer, old pond less fertilizer or no fertilizer. After a few days, the food organisms will decay and the fertilizer will need to be added. Step 4: Under the seedlings, determine the density according to the conditions of the water source, pond size, management level, and post-sales expectation. Generally, the bio-density of the bait is larger (typically 30-50 thousand mu). The initial two to three days of the lower pond may not be fed. Focus on observing fish fry bubbles. If it does, splash salt, activate the aerator, or enter a new hydrolysis solution. Step 5: Topdressing, once the food organisms are attenuated, they can be topdressed in sunny mornings. You can use rotten farmyard fertilizers, or you can use commodity fertilizer and aquatic products. Laotang does not recommend using farmyard fertilizers. The novice farmer must remember to use: Less fertilizer, diligent fertilization. On the issue of top dressing, first of all, rotted farmyard fertilizers. The teaching materials require sealed fermentation. A layer of quicklime layer of manure cut off the air for more than seven days. Pig manure, cow dung, and no poultry are recommended. The sixth step: feeding training, according to the density of the pond food organisms and the size of the fry timely artificial feeding training. If food organisms are not cultivated or are prematurely reduced, the size of the fry is very small and it is necessary to feed egg yolks, soya milk, or milk or milk powder. If the food organism can persist in more than one centimeter of the fish, it can directly feed the powdered feed opening. Feeding principle: A small number of times, feeding around the pond, try to feed once an hour. Step 7: When replenishing water, when the water is released, the water does not have to be deep. It can be four to fifty centimeters (the higher the temperature is in the season, the stronger the light is, and the initial depth needs to be deepened). New water must be added after the water is released (filtering) This is the law that the food organism continues and the spray grows at high speed. Step 8: Disease prevention. When the waterflood reaches a height of three to four centimeters, there is a disease peak, which is mainly parasitic on trichodinosis. At this time, the fry is small in size, poor in resistance and poor in drug resistance. It is necessary to select medicines, calculate the water body, and clear the morning. Apply medicine. The ninth step: Pull the net to exercise, can be carried out in fish fry more than three centimeters (inch-inch), the net must be fine and soft. After 25 days of rearing, the fry can grow to three to five centimeters. At this time, it can be divided into ponds or sold. However, you must exercise more recently. Step 10: Divide the pond or sell it. This is the key to high yield. The more the fish is sold, the more productive it is. When the time is divided, if there are 500,000 seedlings under an acre, survival can be divided between 50% and 3 centimeters, and the pond rule can be divided. The earlier the pond is divided, the longer it is better. supplement: 1. Regarding the use of em strains, photosynthetic bacteria and Bacillus can be considered as commercial fertilizers in the cultivation of aquatic plants. 2. Regarding the quality of the spray, there is little room for selection, but the method of identification still tells everyone that when the bag is not bagged, it can be topped with water (traveling against the water) and no dead flowers (white) after bagging. 3. The spray can swim, when the specification is small, can not eat powder, powder in the fry grow to more than a centimeter to eat. 4. About rotifer peaks, the old pond is filled with lime clear ponds about four days after the injection of water. Transparent tubes can be used to put some pond water in front of the sun, and you can see the rotifers swimming, or microscopic examination, the horns, Rao Foot species (that is, red worms) can be seen with the naked eye. Cladocera can not swim fast in water and cannot swim in a straight line. Rafting class can. These feeds are generally only needle-sized, with red, yellow, white, and even green bugs. The general hordes of activities are easy to see and it is easy to evaluate the density of pond food.
The protein content of oats is as high as 12%-18%, fat 6%-8%, starch 21%-55%, more than other commonly used grains, in addition, oats are rich in vitamin B1, vitamin B2 and vitamin E and trace elements, calcium, phosphorus , iron, riboflavin and saponins unique to cereal crops, can significantly reduce cardiovascular and liver cholesterol. Oatmeal is not only rich in nutrients, but also has high nutritional value, and has been listed as a health food.
