Last Updated: 2024/11/23, Pelteobagrus fulvidraco cultured in ponds with other aquatic species has the advantages of simple operation, low investment, easy feeding, fast growth and high benefit, so it is a high-yield feeding method to improve the utilization rate of water surface. The main results are as follows: 1 the cage is stitched with polyethylene mesh, which is 2m long, 2m wide and 1.2m high, and the mesh is 0.5~1cm. The cage adopts a closed stretcher floating type, the bottom uses 9-purpose mesh cloth as the cushion, and the edge of the cushion is high 20cm, in order to reduce the loss of bait, and the upper part of the cage is higher than the water surface 30cm.

1 net cage setting

The cage is stitched with polyethylene mesh, which is 2m long, 2m wide and 1.2m high. The mesh is 0.5~1cm. The cage adopts a closed stretcher floating type, the bottom uses 9-purpose mesh cloth as the cushion, the edge of the cushion is high 20cm, in order to reduce the loss of bait, the upper part of the cage is about 30cm above the water surface. A square plastic basket with high 10cm and side length 30cm made of 18 mesh polyethylene window screen is used as a dining table, which is placed in the middle of the box, with one in each box. The cage is set at the inlet of the fish pond, and there are 3 fish ponds per mu (667 square meters). Cages can also be set in spacious waters with fresh water quality, sufficient dissolved oxygen, shelter from the wind and sun, and no pollution, arranged in a "one" shape, with a box spacing of 4m and a row spacing of about 10m. Transplant water hyacinth or water peanut which accounts for about 2 / 3 of the cage area.

2 fish fingerling restocking

The cage was launched 1-2 weeks before the fingerling was released. Fish species are required to be disease-free, injury-free, physically strong and neat in specifications. There are 100,150 large size yellow croaker fingerlings with a tail weight of about 20g per square meter.

3. Feeding and management

3.1 Feed

Common baits include small miscellaneous fish, snail clam, @ # @ 254 fish, silkworm pupa, viscera of livestock and poultry and animal blood, which are fed regularly, positioned, qualitatively and quantitatively to ensure that yellow croaker can eat well and grow rapidly.

3.2 Pipe water

Keep the water quality fresh and sufficient dissolved oxygen. Observe the activities of the fish every day and check whether the cage is damaged, fish out the sick fish and dead fish in the cage, and keep the water in the cage clean. Clean the cage once a week to ensure the normal exchange of water inside and outside the cage. Adjust the height of the cage in time when the water level changes.

(4) Disease control

Soak the cage with bleach solution for 30 minutes before entering the water; wash the fish with salt solution before entering the box to kill surface bacteria and parasites; sprinkle and disinfect the whole box with raw lime water every 10 to 15 days; regularly hang bags with the mixture of copper sulfate and ferrous sulfate; bait made of antibiotics for 2 days every 20 days or so.
