This invention discloses a method for co-culturing giant freshwater prawns (Macrobrachium rosenbergii) with shrimp, grass, and fish based on probiotic regulation, and its application. This invention constructs a three-dimensional ecological system with shrimp as the main body, grass as the protector, and fish as a supplement. Elodea and water spinach purify the water, silver carp and crucian carp decompose uneaten feed and feces, and a compound microbial preparation of Lactococcus gasseri C6a2 regulates water quality, while a biological bottom conditioner improves the bottom sediment, achieving precise ecological regulation of the aquaculture environment. This invention does not rely on chemical agents, effectively inhibits ammonia nitrogen accumulation, reduces disease incidence, and significantly improves the survival rate and size of giant freshwater prawns, achieving a win-win situation for both ecological and economic benefits.

The present application relates to the technical field of feeding of crucian carp, and discloses a compound functional feed for repairing carbonate alkali damage of crucian carp, which is composed of alpha-ketoglutaric acid, linoleic acid, laurylene and basic feed, wherein the weight ratio of the alpha-ketoglutaric acid accounts for 1.5% of the total weight of the compound functional feed for repairing carbonate alkali damage of crucian carp, and the weight ratio of the linoleic acid accounts for 0.7% of the total weight of the compound functional feed for repairing carbonate alkali damage of crucian carp. The compound functional feed for repairing carbonate alkali damage of crucian carp can significantly enhance the repair capacity of the tissue cells of the crucian carp, improve the disease resistance of the crucian carp, reduce the risk of diseases and promote the energy metabolism process of the crucian carp, so as to ensure the efficient use of energy and maintain the normal homeostasis of the body.

This application discloses a method for periodically feeding vine tea ultrafine powder in aquaculture and its application. The method includes the following steps: mixing vine tea ultrafine powder into aquatic animal feed at an addition rate of 1% to 8% of the total feed weight, and feeding it using a periodic feeding pattern; the periodic feeding pattern consists of continuous feeding for 7 days, followed by a 7-21 day break, which constitutes one cycle. This application, by pulverizing vine tea to an optimal particle size of 300 mesh, and by optimizing the optimal addition rate of 4% and the periodic feeding strategy of "7 days of continuous use, 14 days of break," fully utilizes the antioxidant and immune-enhancing effects of vine tea while effectively avoiding the potential liver and kidney burden and immunosuppression risks associated with long-term continuous use. Large-scale application trials show that this method achieves a protection rate of 52.91% to 65.14% in various aquatic animals, including crucian carp, largemouth bass, whiteleg shrimp, carp, and tilapia, demonstrating significant economic benefits and promising prospects for industrial application.

The application discloses a Chuzhou crucian carp anti-aeromonas hydrophila ability prediction method and system based on data fusion, which comprises collecting physiological and biochemical, immune-related gene expression and post-infection phenotype multi-source heterogeneous data, and screening a characteristic variable set through alignment processing; an adaptive weighted fusion strategy is used to generate a fusion feature matrix, which is input into an improved deep learning model to train a preliminary prediction model; model parameters are optimized and a decision boundary is corrected through cross-validation to obtain an optimal prediction model; and the prediction data is input into the model after the same processing, and a quantitative result is output. In the method, the adaptive weighted fusion strategy realizes deep integration of data through feature extraction, redundancy elimination and weight optimization, the improved deep learning model adopts a hybrid network architecture and introduces an attention mechanism, and cross-validation is used to train and verify multiple groups of samples to optimize parameters, so that the prediction accuracy and generalization ability are effectively improved, and an efficient technical means is provided for evaluation of the stress resistance of Chuzhou crucian carp.
