The invention provides a lactobacillus pentosus and a preparation method and application of bacteriocin of the lactobacillus pentosus. The name of the strain is lactobacillus pentosus YCL31, and the strain is preserved in Guangdong Microbial Culture Collection Center (GDMCC) on June 25, 2025, the preservation address is the 5th floor of the building 59, No. 100 courtyard, Xianlie Middle Road, Guangzhou, and the preservation number is GDMCC No: 66589. The bacteriocin separated and purified from the metabolite of the bacterium can destroy the morphological structure of the vibrio parahemolyticus and inhibit the toxicity of the vibrio parahemolyticus, can also achieve the effect of remarkably inactivating the vibrio parahemolyticus in a metapenaeus ensis system, can effectively delay the spoilage of the metapenaeus ensis, and has a good application prospect as a bacteriostatic agent or preservative. Therefore, development and application of the novel bacteriocin have important reference value in related fields.

The invention discloses a metapenaeus ensis breeding management method and system based on data analysis, and the method comprises the steps: constructing a water quality anomaly detection model based on a generative adversarial network, obtaining environment monitoring information, and carrying out the abnormal water quality detection of a breeding region; evaluating the breeding quality influence degree under the current water quality according to the water quality anomaly detection information, and performing regulation and control early warning; performing disease monitoring on the metapenaeus ensis in the target breeding area to obtain disease monitoring information, performing disease prediction in combination with the water quality anomaly detection information, and analyzing the cause of the disease; noise identification analysis and noise tracing are carried out on the breeding area according to the environment monitoring information, and noise abnormity early warning is carried out; according to the disease type and the disease condition of the metapenaeus ensis in the target breeding pool, breeding feed optimization is carried out. The breeding management comprehensiveness of the metapenaeus ensis is improved, meanwhile, breeding feed optimization is carried out for the breeding ponds with diseases so as to enhance the disease resistance of other shrimps in the target breeding ponds, and the breeding quality is improved.

The invention relates to the technical field of metapenaeus ensis culture, in particular to a waste cleaning device for metapenaeus ensis seed culture, which comprises a mounting base, a filter cylinder rotating around the mounting base is arranged on the outer side of the mounting base, and a fixed cylinder is fixedly arranged in the middle of the filter cylinder in a penetrating manner; the water suction pipe and the water drainage pipe are respectively positioned at the upper half part and the lower half part of the filter cartridge and are respectively communicated with the two compartments in the filter cartridge; the surface of the drainage pipe is provided with drainage ports; the device has the advantages that the mounting base is fixed to the bottom of the culture pond, the filter cartridge rotating around the mounting base is arranged on the outer side of the mounting base, the water outlet is formed in the surface of the water drainage pipe, and the water pump pumps water through the water suction pipe; and counter-acting force generated by water flow on the drainage pipe pushes the drainage pipe and the water suction pipe to rotate around the mounting base integrally, so that the cleaning area is automatically changed, manual field intervention is not needed, and use is more convenient and labor-saving.

The present application relates to the technical field of enclosure shrimp culture, in particular to a waste cleaning device for enclosure shrimp fry culture, which comprises: a mounting base, a filter cylinder rotating around the mounting base is arranged on the outer side of the mounting base, a fixed cylinder is fixedly arranged in the middle of the filter cylinder; a water suction pipe and a drain pipe are respectively arranged in the upper half and the lower half of the filter cylinder, and the water suction pipe and the drain pipe are respectively communicated with two compartments in the filter cylinder; a drain port is arranged on the surface of the drain pipe; the beneficial effects are as follows: the mounting base is fixed at the bottom of the culture pond, the filter cylinder rotating around the mounting base is arranged on the outer side of the mounting base, the drain port is arranged on the surface of the drain pipe, the water pump performs water suction through the water suction pipe, the water flow is discharged downwardly through the inclined drain port to impact the bottom of the pond, the reaction force generated by the water flow on the drain pipe pushes the drain pipe and the water suction pipe to rotate as a whole around the mounting base, so that the cleaning area can be automatically changed, manual on-site intervention is not needed, and the device is more convenient and labor-saving to use.
