[0002] The meat of the perch is high-protein meat, rich in vitamin A and vitamin B, and is beneficial to the liver, kidney, spleen and stomach, and has a therapeutic effect on cold and cough, can relieve cough and expectoration, and is rich in various trace elements such as calcium, magnesium, zinc and selenium. There is also a lot of copper element in the blood of the perch, copper can maintain the normal function of the nervous system and participate in the function of the key enzymes of various material metabolisms, and people lacking in copper element can eat the perch to supplement. The Micropterus salmoides is also called large-mouthed black perch, belongs to the order Perciformes, the sunfish family and the black perch genus in taxonomy, is originally from the Mississippi River system in California, USA, is a kind of meat-eating fish with delicious meat, no intermuscular spine, fast growth, easy to catch, and relatively wide temperature adaptation. The Micropterus salmoides basically grows wild in rivers and lakes, and is extremely rare and expensive due to its delicious meat.

[0003] At present, the culture method of the Micropterus salmoides has high density, slow growth, many diseases, and high drug use, and poor economic benefits. Although the Micropterus salmoides can naturally spawn in ponds with fresh water and water grass, the spawning rate is low, the size of the fry is uneven, and the fry is easy to be cannibalistic, and the culture density is not easy to control, and the individual size difference is serious. In the culture process, the feed nutrition is not comprehensive, mainly commercial expanded feed is fed, and the supply of vitamins and minerals is insufficient, resulting in low feed utilization rate, and feed and feces are the main factors causing water environmental pollution; in addition, the water quality requirement in the culture process of the Micropterus salmoides is also very strict, and pesticide and water pollution can cause diseases and death of the Micropterus salmoides.

[0004] Based on the above reasons, it is necessary to improve and modify the existing artificial culture and fry culture technology of the Micropterus salmoides to improve the artificial culture quality. Therefore, it is an urgent problem for those skilled in the art to provide a safe and efficient comprehensive regulation and control method for the Micropterus salmoides. SUMMARY

[0005] Therefore, the application provides a safe and efficient comprehensive regulation and control method for the Micropterus salmoides, which improves and modifies the existing artificial culture and fry culture technology of the Micropterus salmoides to improve the artificial culture quality.

[0007] A safe and efficient comprehensive regulation and control method for the Micropterus salmoides, the method comprises using a microorganism maintenance agent and a mineral to fertilize and feed water before fry release.

[0008] This invention uses a combination of microbial preservatives and minerals to fertilize the water and cultivate fish, efficiently promoting algae growth and fertilizing the water. This fosters the rapid growth of beneficial phytoplankton and animals in the water, while reducing the levels of toxic and harmful substances such as ammonia nitrogen, nitrite, and hydrogen sulfide. It also selectively cultivates easily digestible beneficial algae (such as Chlorella and diatoms) in the water, inhibiting the growth of harmful algae such as cyanobacteria. This keeps the pond water "fertile, vibrant, fresh, and clean," increases dissolved oxygen levels, and promotes fish growth.

[0009] Preferably, the specific steps of the fertilization and water culture are as follows: mix the microbial care agent and minerals with 50-100 times the amount of aquaculture water, stir evenly, soak overnight, and then sprinkle the mixture throughout the pond on a sunny morning the next day.

The method for safe and efficient integrated regulation and aquaculture of California bass according to claim 1, characterized in that, This also includes the preparation of the aquaculture ponds, the specific conditions of which are: The aquaculture ponds are 4-10 mu in size and 1.8-3m deep. The pond walls are sloping, with a slope of 30-60° for both the pond walls and the pond bottom. The pond bottom includes pond mud. The aquaculture pond is also equipped with a water inlet, a feeder, and an aerator.

4. The method for safe and efficient integrated regulation and aquaculture of California bass according to claim 1, characterized in that, This also includes the preparation of the rearing pond before stocking, and the specific steps are as follows: (1) Drain the pond water 15-30 days before stocking, sprinkle quicklime or bleaching powder throughout the pond, and expose the pond to the sun for 5-7 days. (2) After completing step (1) of sun-drying the pond, add aquaculture water to the pond and expose it to the sun for 5-7 days, then sprinkle stress-reducing drugs.

5. The method for safe and efficient integrated regulation and aquaculture of California bass according to claim 1, characterized in that, This also includes seedling release and aquaculture management, with the following specific steps: (1) Stocking: After the fish fry transport vehicle arrives at the pond, immediately check the pond water temperature and the fish fry transport water temperature. If the temperature difference exceeds 3℃, water needs to be slowly pumped into the transport vehicle's water tank until the fish fry transport water temperature and the pond water temperature difference is <3℃. If the temperature difference is <3℃, the fish fry can be directly released into the pond from the water hose. One to two hours after stocking, spray the entire pond with an anti-stress medication. Five to eight hours after stocking, apply povidone-iodine to the entire pond. (2) Management of seedlings and adult fish farming 2-1) During the seedling rearing period: 1-2 days after stocking, feed the fish with California bass seedling feed twice a day, with the amount of feed being 2-4% of the fish's body weight. Adjust the amount of feed every 7 days. During the seedling rearing period, a combination of microbial care agent and minerals is sprayed into the entire pond every 5-7 days for nutrient cultivation. 2-2) Adult fish farming management: After the largemouth bass grows to 0.2 catties / fish, feed them with largemouth bass fry feed twice a day, with the amount of feed being 1.5-2.5% of the largemouth bass's body weight. Adjust the feeding amount every 7 days. Fertilizer and water culture were carried out using a combination of photosynthetic bacteria, spore-forming bacteria, and the aforementioned mineral combination. 3) Fish health care and disease prevention During the breeding period, feed multivitamins every 14-15 days for 5 days. After the multivitamin feeding ends, feed liver-protecting Chinese herbal medicine preparations in the feed for 10 days. Prevention and control of California bass iridovirus: Before stocking, test for infectious spleen and kidney necrosis virus, largemouth bass iridovirus, rhabdovirus, and Nocardia. If no iridovirus is detected, stock the fry. On the day of stocking, send 10-20 fry to an institution for another test. If iridovirus is not detected at the time of stocking, proceed with normal farming operations and test every half month thereafter. If iridovirus is detected during the farming process, administer anti-stress medication first, then stop feeding for 1-2 meals, reduce the feed by 20% and feed with multivitamins for 5-7 days. At the same time, sprinkle compound carbon source throughout the pond, and sprinkle povidone-iodine on the evening of the same day. 4) Water quality requirements during aquaculture: dissolved oxygen > 6 mg / L, pH value of water body controlled at 7.8-8.5, water transparency 20-40 cm, ammonia nitrogen content < 1 mg / L, nitrite content < 0.15 mg / L, hydrogen sulfide content < 0.1 mg / L.

6. The method for safe and efficient integrated regulation and aquaculture of California bass according to claim 1, characterized in that, This also includes fish sales management, the specific steps of which are as follows: Feed the fish with multivitamins for 5 consecutive days, 7 days before selling them; Stop feeding the fish 1-3 days before selling them; One to two hours before netting the fish on the day of sale, apply an anti-stress medication to the entire pond.
