AI Technical Summary

Technical Problem

Existing timed and fixed-point feeding methods cannot effectively simulate the long-term feeding habits of herbivorous fish in their natural environment, leading to fat accumulation in the fish's body, relaxation of muscle fibers, differences in growth curves, and the risk of malnutrition or viral infection in the aquaculture pond. Furthermore, long-term feeding methods are easily affected by environmental changes, resulting in feed waste and water quality deterioration.

Method used

Monitoring nodes, including cameras and feeders, are arranged in a ring or circular pattern in the farm. Risk status is identified by calculating feeding fluctuation values ​​and abnormal feeding factors. Feeding fluctuation values ​​are centralized, STL decomposed, and Spearman correlation analysis is used to dynamically evaluate feed feeding efficiency and adjust the feeding amount.

Benefits of technology

It improves feed feeding efficiency, reduces the risk of fat accumulation in fish, balances individual growth, reduces feed waste and water quality deterioration, and enables sensitive risk identification and real-time adjustment under long-cycle feeding methods.

Abstract

The present application belongs to the technical field of aquaculture, and proposes a feed feeding efficiency evaluation method and system, specifically: first, the monitoring node camera is arranged in the breeding farm, the real-time monitoring data is read at the monitoring node to calculate the feeding fluctuation value, then the feeding abnormal factor is calculated according to the feeding fluctuation value, the feeding risk state is identified, and finally the feed feeding efficiency is evaluated through the feeding risk state. The feeding abnormality is calculated by the feeding fluctuation value of each sampling point of each monitoring node in a monitoring period, the micro recession performance of the fish feeding enthusiasm observed by each monitoring node in the long-period feeding strategy is captured, the identified feeding risk state can more sensitively prevent the excessive feeding amount of feed, avoid the risk of feed waste and water quality deterioration, and improve the feed utilization efficiency and breeding quality under the long-period feeding strategy.
