Prawn and grass symbiotic culture method

Abstract

The invention discloses a prawn and grass symbiotic culture method. The prawn and grass symbiotic culture method comprises the following steps that S1, a 6 x 3 x 3 natural pond is built, water is dissolved with quicklime, the quicklime is uniformly sprayed to disinfect, the whole pond is disinfected with niclosamide 340 after 10 days, disinfecting is conducted for 5 days, a water inlet valve is arranged, aquatic plants with stem length of more than 10cm is selected, the aquatic plants is planted on a floating mat, continuously culturing is conducted for 3-4 days, and prawn seedlings are placed; and S2, dissolved oxygen content, ammonia content and nitrogen content of water are monitored, and the number of prawns and the aquatic plants and shelling condition, exercise amount and food intake of the prawns are observed by using an underwater camera, a reinforcement learning algorithm is adopted, and according to the dissolved oxygen content, the ammonia content and the nitrogen content of the water and the number of the prawns and the aquatic plants, the putting amount and the illumination degree of drugs or fertilizer and water grass culture products for inhibiting protists and oxygenates are added. According to the prawn and grass symbiotic culture method, a deep learning model and a reinforcement learning model are used for automatic dynamic adjustment, macroscopic regulation and control and real-time adjustment are achieved, manual control is not needed, and aquaculture achievement of the prawns and the aquatic plants can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of symbiotic cultivation of prawns, in particular to a method for symbiotic cultivation of prawn grasses. Background technique [0002] The carbon dioxide produced by protists and prawns can increase the survival rate of aquatic plants. At the same time, aquatic plants can provide nutrients for protists and prawns, forming an ecological symbiosis. In order to ensure the oxygen supply and growth of prawns, it is usually necessary to inhibit the protists with drugs or use fertilizer and water The product is cultivated, but if the amount is not controlled enough, it will lead to too many aquatic plants, resulting in the death of a large area of ​​aquatic plants and aggravating the growth of protozoa. Therefore, it is necessary to regulate the dosage of drugs and fertilizers and water products that inhibit protozoa. , to form an ecological balance, which is conducive to promoting the growth of prawns, but the cu...

[0002] The carbon dioxide produced by protists and prawns can increase the survival rate of aquatic plants. At the same time, aquatic plants can provide nutrients for protists and prawns, forming an ecological symbiosis. In order to ensure the oxygen supply and growth of prawns, it is usually necessary to inhibit the protists with drugs or use fertilizer and water The product is cultivated, but if the amount is not controlled enough, it will lead to too many aquatic plants, resulting in the death of a large area of ​​aquatic plants and aggravating the growth of protozoa. Therefore, it is necessary to regulate the dosage of drugs and fertilizers and water products that inhibit protozoa. , form an ecological balance, which is conducive to promoting the growth of prawns, but the current regulation is usually based on the experience of farmers, and real-time regulation cannot be achieved, which greatly affects the breeding efficiency of prawns and aquatic plants.
