Based on the culture conditions and method of *Propionibacterium f. reudenreichii* subsp. *shermanii* in this invention, the optimal amount of carrageenan added is selected as 0.6%, which significantly enhances the antibacterial activity of the *Propionibacterium f. reudenreichii* subsp. *shermanii* metabolites.

This invention relates to the field of black-spotted catfish farming technology, and in particular to a method and apparatus for black-spotted catfish farming. The apparatus includes a farming pond, a sludge treatment component, a temperature control module, a drive component, and a heat-insulating shed component. The sludge treatment component is fixedly connected to the farming pond, and the temperature control module is fixedly connected to the inner wall of the farming pond. The catfish are placed in the farming pond for farming, and the temperature is controlled at 8℃-9℃ by the temperature control module. When a large amount of fish excrement and debris is generated at the bottom of the pond, the drive component activates the sludge treatment component to collect and clean the sludge and clean the hourglass farming plate, preventing blockage of the hourglass farming plate and avoiding water quality issues and fish diseases. When the weather is cold or too hot, or when the temperature exceeds the minimum and maximum thresholds, the temperature control module activates the heat-insulating shed component to maintain a stable water temperature in the farming pond and ensure an optimal farming environment.
