First, to improve the pond environment The past fish species pools are generally small and shallow, so that floating species often occur, especially in the late, almost every day floating head. This not only inhibits the growth of fish species, but also affects water quality. Therefore, it is necessary to improve the pond environment so that the water depth reaches 2 to 3 meters, and the area increases to 4.5 to 7 to 5 acres. At the same time, it is equipped with an aerator (0.5 kilowatts per mu). Under this condition, as long as the irrigation and drainage are convenient, feeding and fertilizing can keep up, and the summer fish and grass can reach 10 centimeters in the next pool, which is about 3 centimeters longer than the ordinary shallow pond. In the later stages of growth, weight gain can be increased. Therefore, the survival rate and yield of the fingerlings are significantly higher than those in shallow ponds.
Second, timely early stocking in order to ease the contradiction between water quality, food, and space between the summer flowers and grass carp and the fish, grass carp should be obtained as soon as possible. At present, the use of greenhouse artificial propagation of early propagation seedlings is more effective. The stocking density of the total production of 500 kg or more per acre cultivation pond is 3000- 3,500 fish tails, 800-1000 tail heads, 1000-1500 tails and 1,500-2,000 tails.
Third, after cultivating the natural food clearing pond, 400-500 kg of organic fertilizer is applied per acre. Use bamboo to separate the surface of the water into a cross, and then put 15 to 25 kg of duckweed per acre. After 5 months, put 35 to 40 kg of organic fertilizer every 2 days, or use 1 kg of ammonium bicarbonate and 500 g of superphosphate to dilute the whole pool, in order to accelerate the breeding of duckweed and cultivate suitable natural food.
Fourth, pay attention to feeding flushed Xiahua grass fish do not have to control the amount of food after the pool, it should be done after the vote, requiring the fish in the pool with fish before the fish more than 10 cm, and uniform specifications. In the early summer, Xiahuaxiachi mainly feeds on branches and duckweeds, and 2 to 3 days before the duckweed is eaten, so that the fish can switch to the shredded tender grass or black-leaf algae. Special attention should be paid to high temperature, hot and thunderstorms, the fish species can easily float head, loss of appetite, and proper control of feeding. After the high temperature season is over, when the water temperature falls below the optimal water temperature range below 30°C, it is necessary to seize the time to feed enough feed to ensure rapid growth in the later period. In general, the annual feed amount per mu is 800 to 1,000 kg, and the feed for green feed is 1500 to 2000 kg.
Grass carp enjoys fresh water quality. The first-year-old grass carp is mainly herbivorous, so it has more manure and water quality. Therefore, it must be flushed frequently. Within 20 days after Xiahuaxiaxia, new water should be refilled once every 2 days, each time is 10cm deep; after 20 days, in addition to regular replenishment of new water, part of the old water should be discharged, and the transparency of water quality can be maintained at about 35cm. In order to promote the appetite of grass carp, the number of flushes will gradually decrease after late September.
Fifth, to strengthen the prevention of fish diseases before the lower pool of grass fish with 3% to 4% of the saline or 20 mg / potassium manganate solution dip for 15 to 20 minutes, to kill the body of the fish or the axillary pathogens. When the grass carp grows to about 10 cm, an inactivated vaccine for grass carp hemorrhage is used to prevent grass carp bleeding. At the end of July and early August, 20-30 mg/litre quicklime solution is sprayed once in a whole to control bacterial gill disease; 0.5 g/l crystal trichlorfene and 0.2 mg/g are used in mid-August and mid-September. Raise the ferrous sulfate Quanchiposa once to prevent foot inflammation. At the same time, furazolidone was used for 2 courses (each treatment course was 3 to 4 days, and 1 kg of bait contained 1 to 1.5 grams of drug to make pellets).
