2、算法规则：对鱼类投喂量在基础投喂量计算的基础上，结合环境参数修正因子、鱼群行为修正因子和残饵率修正，采用如下综合算法： 基础日投喂率：根据平均体重设定：0.2–0.5 kg：1.8%–2.5%/日，0.5–1.0 kg：1.2%–1.8%/日，1.0–2.0 kg：0.8%–1.2%/日； 日总投喂量 = 平均体重(kg/尾) × 放养密度(尾/亩) × 基础日投喂率； 环境修正因子 = 1 - (0.35 × |溶氧 - 溶氧最优值| + 0.30 × |水温 - 水温最优值| + 0.20 × |pH - pH最优值| + 0.15 × |氨氮 - 氨氮最优值|)； 溶氧最优值：6.0 mg/L，权重：0.35； 水温最优值：26.0 ℃，权重：0.30； pH最优值：7.0，权重：0.20； 氨氮最优值：0.1 mg/L，权重：0.15； 行为修正因子 = 0.4 × 鱼群活性评分/100 + 0.4 × 摄食活跃度评分/100 + 0.2 × 鱼群聚集度/100； 历史残饵率修正系数:根据历史残饵率设定（< 3%：1.10，3%–5%：1.00，> 5%：0.80）； 当日投喂次数根据季节设定：春季/秋季3次（8:30、11:30、16:30），夏季4次（7:00、9:30、17:30、20:00），冬季1-2次（中午时段）; 最终单次投喂量 = (日总投喂量 × 环境修正因子 × 行为修正因子 × 历史残饵率修正系数) / 当日投喂次数。

3、数据分析： 通过算法规则获得最终单次投喂量去进行投喂，不仅能显著减少饲料浪费，更能精准匹配鱼类不同生长阶段、不同环境下的进食需求，保障其健康生长；从源头可降低历史残饵率，减少残饵分解产生的有机污染物积累，避免水体溶氧消耗、氨氮超标等问题，有效缓解因过量投喂导致的水质恶化，优化下一次测量数据，更精确的得到最终单次投喂量数据，为智慧养殖的降本增效与绿色生态发展提供了可落地的技术路径。

Research on Feeding Management Methods for Large-Scale Aquaculture Farms Based on Farmed Crucian Carp Feeding Analysis Data

This analysis integrates multi-source data including dissolved oxygen, water temperature, pH, ammonia nitrogen, meteorological conditions and fish activity, to study the influence law of feed feeding strategies on the growth rate of crucian carp, and realize scientific and precise feeding management. It is mainly applied in scenarios such as daily precise feeding, risk warning and emergency response, cost control and optimization, data-driven decision-making, and compliance quality traceability. Through technical means such as multi-parameter fusion, real-time monitoring and data analysis, it can improve feed utilization rate, reduce breeding costs and ensure breeding safety.

For the aquaculture industry, this not only avoids feed waste and residual feed pollution, reduces breeding costs, but also relies on data anomalies to warn of risks such as water quality deterioration and fish stress, reducing disease losses; furthermore, it can transform effective experience into a standardized system, promoting the transformation of crucian carp farming from an "experience-based" extensive model to a refined one.

For society, precise feeding reduces resource consumption and environmental carrying pressure, which is consistent with the concept of green agriculture; scientific feeding improves the quality of crucian carp and breeding success rate, reduces the demand for emergency medication to ensure food safety, and stabilizes market supply; at the same time, cost reduction and efficiency improvement directly increase the income of farmers, drive the development of the industrial chain, and inject industrial momentum into rural revitalization.

1. Data Collection: Enterprises conduct data detection and collection on fish ponds, using water quality sensors to collect data. The original data fields obtained after sorting are: aquaculture pond number, fish species, recording time, week number, season, activity level, dissolved oxygen, water temperature, pH, ammonia nitrogen, fish activity score, feeding activity score, fish school aggregation degree, average body weight, stocking density, and historical residual feed rate.

2. Algorithm Rules: Based on the calculation of the basic feeding amount, the feeding amount for fish is corrected with environmental parameter correction factors, fish school behavior correction factors and residual feed rate correction, and the following comprehensive algorithm is adopted:
Basic daily feeding rate: Set according to the average body weight: 0.2–0.5 kg: 1.8%–2.5% per day; 0.5–1.0 kg: 1.2%–1.8% per day; 1.0–2.0 kg: 0.8%–1.2% per day;
Total daily feeding amount = average body weight (kg/ind.) × stocking density (ind./mu) × basic daily feeding rate;
Environmental correction factor = 1 - (0.35 × |dissolved oxygen - optimal dissolved oxygen value| + 0.30 × |water temperature - optimal water temperature value| + 0.20 × |pH - optimal pH value| + 0.15 × |ammonia nitrogen - optimal ammonia nitrogen value|);
Optimal dissolved oxygen value: 6.0 mg/L, weight: 0.35; Optimal water temperature value: 26.0 ℃, weight: 0.30; Optimal pH value: 7.0, weight: 0.20; Optimal ammonia nitrogen value: 0.1 mg/L, weight: 0.15;
Behavior correction factor = 0.4 × fish activity score/100 + 0.4 × feeding activity score/100 + 0.2 × fish school aggregation degree/100;
Historical residual feed rate correction coefficient: Set according to the historical residual feed rate (< 3%: 1.10, 3%–5%: 1.00, > 5%: 0.80);
The number of daily feeding times is set according to the season: 3 times in spring/autumn (8:30, 11:30, 16:30), 4 times in summer (7:00, 9:30, 17:30, 20:00), 1-2 times in winter (noon time);
Final single feeding amount = (total daily feeding amount × environmental correction factor × behavior correction factor × historical residual feed rate correction coefficient) / number of daily feeding times.

3. Data Analysis: Using the final single feeding amount obtained through the algorithm rules for feeding can not only significantly reduce feed waste, but also accurately match the feeding needs of fish in different growth stages and environments, ensuring their healthy growth; it can reduce the historical residual feed rate from the source, reduce the accumulation of organic pollutants generated by the decomposition of residual feed, avoid problems such as water body dissolved oxygen consumption and ammonia nitrogen exceeding the standard, effectively alleviate water quality deterioration caused by overfeeding, optimize the next measurement data, obtain more accurate final single feeding amount data, and provide a feasible technical path for cost reduction, efficiency improvement and green ecological development of smart aquaculture.
