Annual increase in fish performance in two seasons

In the same fish pond, the fish will raise two seasons of fish a year. In the first half of the year, the fish will be cultivated. The cultivation of fish species in the second half of the year will increase the utilization rate of fish ponds and increase economic efficiency.

Fish pond conditions:

It is required that the area of ​​the fish pond be suitable and the depth be appropriate. In order to facilitate net fishing and dry pond fishing, generally choose an area of ​​3-15 acres, depth of 1.5-3 meters of fish ponds. It requires sufficient water sources, convenient drainage and irrigation, and convenient transportation. It is important to raise two seasons of fish in one year because fish species, fertilizers, feed, and adult fish enter and leave frequently, and the labor intensity is high.

Production process:

For the first quarter of the year, fish were released from January to February. Feeding was enhanced from March to June, and fish was sold in June. After the season of July 15, the fish of the season will be used for the summer fish species, and will be intensively cultivated from August to October. The fish will be sold at the end of the year from the 11th to the 12th of December.

Adult fish breeding. 1. Fish stocking: Disinfection in clear ponds for 15 days before stocking. The base fertilizer was applied 3 days later. Fish species require the same specifications, robust physique, no disease or injury, and mainly eat large-scale fish. Each acre stocking rearing weight of 200-500 grams of 250 grass carp tail, 200-500 grams tail weight of 100 squid, 50 grams of tail weight of 100 species of squid. When stocking, soak the fingerlings and inject the vaccine.

2. Strengthen rearing: Promote early eating. After the fish is put into use, feed with high-quality pellets and tame the food. At the beginning of March, enter normal feeding. From April to June, we fed 2 times a day, and the amount fed was 3% to 5% of the body weight of the fish, with a suitable amount of green grass such as tender grass and lettuce leaves.

3, adjust the water quality: the transparency of the water body should be reduced in time to add new water, adjust water quality, increase the pool of dissolved oxygen, keep the water transparency of about 25 cm. If necessary, add an aerator, and turn on the oxygen for 1-2 hours at noon on a sunny day.

4, to strengthen the prevention and treatment of fish diseases: mainly prevention and treatment of red skin disease, gill disease, enteritis disease, surface parasitic disease and other diseases. Adhere to the main prevention, once a month water disinfection. Feed the bait every 15 days.

Fish breeding:

Thoroughly clear the pond to disinfect the wild fish before applying the fish, and apply enough basal fertilizer. Fish breeding, soaking and disinfecting operations must be careful to prevent injury. 7 centimeters per mu are stocked with 3000 grass carp species, 5 cm species of carp species are 500 species, and 3 cm species of carp species are 100 species (which can be cultivated in that year). Feeding is mainly based on pelleted feeds. During the period of intensive cultivation from July to October, the daily feeding amount is 8%–10% of the fish’s body weight and it is fed 3 times a day. Fertilization is dominated by organic fertilizers to keep the water quality “fat, live, tender and cool”. Common diseases of grass fingerlings are bleeding and surface parasitic diseases. With bleeding loose, rare earth fish mixed feed to prevent bleeding. Use exterminator once a month to kill parasites.
