Problems solved by technology

In the channel catfish intensive culture mode, high stocking density is the basis for obtaining high breeding returns. However, there are many shortcomings in the current breeding methods, including unstable breeding yield, low yield, weak seedlings, and the growth period. There are no effective preventive measures for the disease, which restricts the further improvement and industrialization of the channel catfish breeding level

Embodiment 1

[0022] A channel catfish runway breeding method, in which 4-8 side-by-side breeding water tanks are built by pouring cement in the middle of the pond, each running water tank is 20-50 meters long, 5-7 meters wide, and 1.5-2.5 meters deep. After the construction is completed, dealkalization treatment is carried out. Specifically, water is directly added to the cement pool, soaked for 10-20 days, and the water is changed every 2-3 days in the middle. Set up a push water aeration area, use the push water aeration device to push the pond water to form a high-dissolved oxygen flow into the water tank, set up a sewage suction channel outside the fish fence on the other side, and use the waste and excrement collection device to collect the breeding manure and excrement. The residue is discharged. During the channel catfish breeding period, the water flow rate of the water tank is controlled by the water pushing device. Specifically, the flow rate of the channel catfish is controlled a...

[0024] A channel catfish runway breeding method, in which 4-8 side-by-side breeding water tanks are built by pouring cement in the middle of the pond, each running water tank is 20-50 meters long, 5-7 meters wide, and 1.5-2.5 meters deep. After the construction is completed, dealkalization treatment is carried out. Specifically, after adding water to the cement pool, add 1g of sodium thiosulfate per cubic meter, and change the water after soaking for 3 days. Set up a push water aeration area, use the push water aeration device to push the pond water to form a high-dissolved oxygen flow into the water tank, set up a sewage suction channel outside the fish fence on the other side, and use the waste and excrement collection device to collect the breeding manure and excrement. The residue is discharged. During the channel catfish breeding period, the water flow rate of the water tank is controlled by the water pushing device. Specifically, the flow rate of the channel catfish is co...

Embodiment 3

[0026] A channel catfish runway breeding method, in which 4-8 side-by-side breeding water tanks are built by pouring cement in the middle of the pond, each running water tank is 20-50 meters long, 5-7 meters wide, and 1.5-2.5 meters deep. After the construction is completed, dealkalization treatment is carried out. Specifically, after adding water to the cement pool, add 20g of acidic sodium phosphate or 250g of phosphoric acid per cubic meter, and change the water after soaking for 2-3 days. A water pushing and oxygenation area is set outside the fish fence, and the pond water is pushed by the water pushing and oxygenation device to form a high-dissolved oxygen flow into the flow tank. Discharge the cultured manure and residues. During channel catfish culture, control the flow rate of the water tank through the water pushing device. Specifically, control the flow rate of the channel catfish at 0.2-0.3 m / s during the channel catfish juvenile stage, and after 4-6 hours Reduce t...

Abstract

The invention discloses a runway breeding method of ictalurus punetaus. According to the runway breeding method, 4-8 breeding launders are built side by side in the middle of a pond through cement pouring; two ends of each launder are blocked by fish screens; a water-driving oxygenation area is arranged outside one side of each fish screen; pond water is pushed to form high-dissolved-oxygen water flow to enter the launders by utilizing a water-driving oxygenation device; and a sewage suction water channel is arranged outside the other side of each fish screen, breeding excrement and residues are discharged through a waste and excrement collection device, and during the breeding period of channel catfish, the water flow speed of the launder is controlled through a water-driving device on juvenile fish and adult fish and different time periods. The runway breeding method of ictalurus punetaus can realize high-density and high-quality breeding of the ictalurus punetaus, can avoid the complex ex-situ purification circulation process of a breeding water body, can realize a large amount of movement of the ictalurus punetaus during breeding so as to improve the feed utilization and reduce manual management cost, and can remarkably improve the economic and environmental benefits of ictalurus punetaus breeding.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a channel catfish raceway culture method. Background technique [0002] Aquaculture is one of the important pillar industries in my country's fishery field. At present, most economic fish in my country are mainly cultivated in ponds, but they are already facing the pressure of structural optimization and technological upgrading. In terms of production efficiency, resource utilization, and environmental Protection and other aspects need to be improved urgently, and the active promotion of factory farming systems meets the requirements for intensification and sustainable development of the aquaculture industry. [0003] Channel catfish is native to the Americas and belongs to the Siluriformes and Catfish family. It is also known as channel catfish. It has the characteristics of fast growth, wide temperature range, and strong disease resistance. It feeds on pellet fee...
