[0022] A method for breeding and raising sea bass with a temperature regulating function comprises the following steps: establishing a breeding pond, dividing an aquatic plant growth zone on one side of the breeding pond, selecting submerged plants, emergent plants and floating plants and transplanting them to the breeding pond, waiting for 8 to 15 days before stocking fry at a stocking density of 3,200 to 4,500 fry per mu, regularly inspecting the breeding pond, and regularly feeding fish feed.

[0023] The area of ​​the aquatic plant growth zone is 25-35% of the total area of ​​the breeding pond. Nets are set up near the aquatic plant growth zone to control the production area of ​​aquatic plants and reduce the coverage of the water area.

[0024] In the specific implementation of the present invention, when the breeding pond is established: the pond area is 10 to 15 mu, the water depth is 2.5 to 3 meters, the bottom of the pond is dried for 30 to 35 days, and after disinfection, the pond is paved with loose sandy soil rich in humus and silt, and the silt thickness is 20 to 35 cm.

[0025] When stocking the fry, they are bathed in salt water for 20 to 35 minutes, and daily oxygenation is also included. The oxygenation time is determined according to the specific dissolved oxygen conditions in the pond. Submerged plants include Vallisneria, Water Chestnut, and Hydrilla verticillata; emergent plants include Acorus calamus, Cattail, and water grass; floating plants include lotus and Euryale ferox.

[0026] It also includes setting up a water quality monitoring center, including data monitoring of the cultivation ponds, including data monitoring of temperature, pH value, dissolved oxygen, ammonia nitrogen, and nitrite, and regulating water quality through monitoring feedback data. Water quality regulation includes regular water changes combined with biological purification to maintain stable water quality;

[0027] The water is changed once every 1 to 2 months, and the amount of water changed is 15% to 25% of the total water volume of the pond. The biological purification is to regularly add beneficial microbial preparations into the pond, and the beneficial microbial preparations include photosynthetic bacteria and nitrifying bacteria. The water quality control requirements are that the water transparency is 30 to 50 cm and the pH value is within the range of 7.0 to 8.5.

[0028] Waste generated during the breeding process (such as fish feces, leftover bait, etc.) can be treated in situ and utilized as resources by constructing ecological floating beds and setting up benthic animal communities (such as snails and clams), thereby reducing environmental pollution, promoting the improvement of the self-purification ability of water bodies, and forming a virtuous cycle ecosystem.

[0029] After the fry are put into the pond, they are fed with complete compound feed. Immune enhancers are added to the bait. The amount added depends on the added species. The feeding amount is flexibly adjusted according to the daily dissolved oxygen and the fish's feeding conditions.

[0030] In one embodiment:

[0031] The pond area is 15 mu, the water depth is 3m, the bottom of the pond is dried for 35 days, and after disinfection, the pond is paved with loose sandy soil rich in humus and silt with a silt thickness of 35cm. When stocking, the fish are bathed in salt water for 35 minutes, and daily oxygenation is also included. The oxygenation time is determined according to the daily dissolved oxygen conditions in the pond. Submerged plants include Vallisneria, Water Chestnut, and Verticillium; emergent plants include calamus, cattail, and water plants; floating plants include lotus and Euryale.

[0032] A water quality monitoring center is set up to monitor the data of the cultivation ponds, including the temperature, pH value, dissolved oxygen, ammonia nitrogen and nitrite. Water quality is regulated through the feedback data from monitoring. Water quality regulation includes regular water changes combined with biological purification to maintain stable water quality.

[0033] The water is changed once a month, and the amount of water changed is 20% of the total water volume of the pond. The biological purification is to regularly add beneficial microbial preparations into the pond. The beneficial microbial preparations include photosynthetic bacteria and nitrifying bacteria. The water quality control requirements are water transparency of 35cm and pH value within the range of 7.0-8.5.

[0034] Waste generated during the breeding process (such as fish feces, leftover bait, etc.) can be treated in situ and utilized as resources by constructing ecological floating beds and setting up benthic animal communities (such as snails and clams), thereby reducing environmental pollution, promoting the improvement of the self-purification ability of water bodies, and forming a virtuous cycle ecosystem.

[0035] After the fry are put into the pond, they are fed with complete compound feed. Immune enhancers are added to the bait. The amount added depends on the added species. The feeding amount is flexibly adjusted according to the daily dissolved oxygen and the fish's feeding conditions.

[0036] In actual application, set up pond A and pond B:

[0037] Pond A: No aquatic plants grow, and the management method is the same as that of general fish ponds

[0038] Pond B: Aquatic plants grow there, and other aspects are the same as those of general fish ponds.

[0039] Pond A showed low feeding appetite and widespread sinus disease in fish, whereas Pond B did not experience this adverse phenomenon.

[0040] The reason is that aquatic plants are planted in a certain space in Pond B, which provides a heat-relief space for fish species during high temperature periods, while regulating the local temperature and dissolved oxygen of the water body, thereby enhancing the stress resistance of the fish species in the pond.

[0041] The maximum temperature, minimum temperature and average value of Pond B are all lower than those of Pond A. At the same time, the temperature change rate of Pond A is smaller than that of Pond B. Specifically, the temperature difference is the local temperature change caused by aquatic plants, which affects the temperature of Pond B.

[0042] At the same time, the dissolved oxygen in Pond B is higher than that in Pond A, and the daily dissolved oxygen change rate in Pond A is higher than that in Pond B. The dissolved oxygen change pattern in Pond B is stable, while that in Pond A is unstable, and explosive growth and cliff-like decline of dissolved oxygen often occur.

[0043] Under the same fish species, breeding area, breeding density, feed and management method, there are obvious differences in growth, disease incidence, feeding habits and feed coefficient.

[0044] In another embodiment:

[0045]

[0046]

[0047] The two ponds were managed and controlled in the same way. During the entire breeding period, there was no disease in the test pond, with only sporadic deaths. In the control pond, there was an outbreak of sinusitis, and stress-induced deaths continued for a week, with more than 230 fish killed.

[0048] Advantages of the present invention:

[0049] 1. It is easy to obtain materials. The price of water plants is low. Most of the wild ponds can be collected. There is no additional cost except labor.

[0050] 2. The economic value of aquatic plants is not taken into consideration, and no additional management is required. It is sufficient to use a net to control their growth, without increasing management costs;

[0051] 3. This plant grows rapidly and can play a role in short-term rapid growth;

[0052] 4. In addition to providing shade and cooling, the roots can also help purify water, as shown in the dissolved oxygen data.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The present invention and its implementation methods are described above, and such description is not restrictive. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design structures and embodiments similar to the technical solution without creativity, which should all fall within the protection scope of the present invention.
