Description

Technical Field

[0001] The invention relates to the technical field of freshwater fish breeding, in particular to breeding equipment and a method for increasing the content of beneficial flavor substances in freshwater fish muscle. Background Art

[0002] Aquaculture is the use of waters available for breeding (including planting) by humans, according to the ecological habits of the breeding objects and the requirements for the environmental conditions of the waters, using aquaculture technology and facilities to engage in aquatic economic animal and plant breeding. It is one of the agricultural production sectors. The development of aquaculture is of great significance, as shown in the following: ① It can provide high-quality animal protein food for humans economically. In animal breeding, fish are aquatic cold-blooded animals. Compared with terrestrial constant-temperature livestock and poultry, fish consume less energy, have high feed conversion efficiency, and have a high content of animal protein in the product. ② It can provide raw materials for industry and is an important source of raw materials for the pharmaceutical industry, chemical industry, feed industry, etc. ③ It plays a significant role in making up for the shortage of marine fishing. With the rapid growth of the world's population and economic development, human demand for animal protein is increasing, but the catch is limited by the renewal of natural fishery resources. Fishery forecasts point out that the trend of increasing annual catch has reached its peak, and in the future, it will not be able to meet the demand by fishing natural fishery resources alone. ④ It is conducive to maintaining ecological balance. In offshore areas, the increase in aquaculture production can reduce fishing intensity and prevent overfishing from causing ecological imbalance; in inland waters, the combination of aquaculture and other agricultural production is conducive to the formation of a virtuous ecological cycle.

9. A method for using the aquaculture equipment for increasing the content of beneficial flavor substances in freshwater fish muscle as claimed in claim 1, characterized in that: The method of use includes the following steps: A. Add the fish feed into the mixing box, turn on the mixing component, and mix the fish feed evenly; B. After the fish feed is mixed, it is discharged onto the discharge plate; C. Control the air pump to blow out gas, which is ejected from the air nozzle to evenly blow the feed into the freshwater fish breeding box; D. The oxygen concentration sensor and hydrogen concentration sensor collect the oxygen content and hydrogen content in the aquaculture water in real time, and the collected values ​​are fed back to the external monitoring terminal in real time; E. If the oxygen content or hydrogen content is lower than the set value, the oxygen flow rate and hydrogen flow rate are adjusted, and the oxygen filling time and hydrogen filling time are controlled at the same time.

10. The method for using the aquaculture equipment for increasing the content of beneficial flavor substances in freshwater fish muscle according to claim 9, characterized in that: The method for processing sensor data in the external monitoring terminal is as follows: a. Establish a data set, wherein the data set includes multiple sub-data sets to be extracted features; b. Perform feature training on the data set to obtain a training model; c. Extract the first keyword and the second keyword in the data set; d. Circularly search each sub-dataset in the data set, using the first keyword and the second keyword as initial conditions to search the sub-dataset; e. If the first keyword or the second keyword is matched in each sub-data set, the data is extracted.
