Third, the bait

  Summer grass carp can be planted in the pond during the vigorous breeding period of the branches, in order to shade the hot sun, it is recommended to cultivate 20-30% duckweed in the pond. The first-in-year grass carp pond can be fertilized after clearing the pond, the amount of fertilizer is calculated according to 400 ~ 500Kg / mu, and then put duckweed or small duckweed seeds 16 ~ 25 Kg / mu, 3-5 months after applying organic fertilizer twice a week, 25 ~ 50 Kg / time, or 1 Kg ammonium bicarbonate with 0.5 Kg of calcium superphosphate diluted after the whole pond is spilled. Sprinkle 3 times a day in the morning, during and in the evening to accelerate duckweed reproduction.

  1 week before stocking, first add 30cm of fresh water, fertilize 300~ 500Kg/mu, and add 50cm of water every 2 days.

Fourth, appropriate amount of seedlings in a timely manner

  According to the weather, pond mouth, breeding mode and other aspects of different conditions, grass carp summer flower stocking quantity is also different, the main fish in the polyculture mode should be released early.

Fifth, strengthen the bait

  Summer flower grass carp seedlings do not have to control the amount of food, you can completely eat and cast. It is required that the grass carp grow to more than 10 cm before entering the pond with cultured fish, and the specifications are uniform. When the summer grass carp enters the pond, it feeds on branches and duckweed, and the small duckweed can be fed with tender dry grass (finely cut) or purple-backed duckweed, black algae and so on 2 to 3 days before eating.

  From July to August, the amount of feeding should be properly controlled, and no feeding should be given at night; in late September, sufficient feed should be ensured and can be fed day and night. In order to promote the digestion of grass carp, increase the amount of feeding, and promote growth, you can mix fish into the feed to adjust the intestinal health of grass carp and promote feeding.
