养殖草鱼存活率检测数据

在水产养殖管理过程中，草鱼存活率数据是衡量养殖技术水平和环境管理成效的重要指标。通过对不同养殖池塘、批次的草鱼投放数量、存活数量等数据的持续采集和跟踪，企业能够精准分析各环节对成活率的影响，及时调整养殖策略，优化饲养管理流程。结合历史存活率数据，可用于预测养殖风险、制定科学的养殖计划、提升经济效益。草鱼存活率数据还可为品种改良、疾病防控、政策申报等提供数据支撑，助力企业实现高效、可持续发展。1、数据采集：通过企业对鱼塘进行数据检测与采集，使用重量法估算和抽样标记发等对鱼塘进行采集数据，整理后获得原始数据字段：养殖池编号、投放时间、检测时间、投放数量、存活数量、死亡原因、养殖周期、负责人、水温、溶氧、pH和氨氮。

2、算法规则：草鱼存活率在基础存活率计算的基础上，结合环境参数修正因子，采用如下综合算法(算法数据依从四舍五入计算)：

基础存活率 = (存活数量/投放数量) × 100%

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：24.0 ℃，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

综合存活率 = 基础存活率 × 环境修正因子

3、数据分析：根据算法规则获得的综合存活率来进行分析，如果存活率降低，该养殖池可能存在环境参数异常、管理不当或疾病风险，需要及时排查水质问题、调整养殖密度、加强疾病防控措施；如果存活率升高，则说明养殖环境适宜、管理措施有效，可以总结经验并推广到其他养殖池，同时考虑适当提高养殖密度以提升经济效益。

In aquaculture management, grass carp survival rate data serves as a critical indicator for evaluating breeding technical levels and the effectiveness of environmental management. Through continuous collection and tracking of data such as the stocking quantity and survival count of grass carp in different culture ponds and batches, enterprises can accurately analyze the impact of each link on the survival rate, timely adjust breeding strategies, and optimize feeding management workflows. Combined with historical survival rate data, it can be used to predict breeding risks, formulate scientific breeding plans, and improve economic benefits. Grass carp survival rate data can also provide data support for variety improvement, disease prevention and control, policy declaration and other aspects, helping enterprises achieve efficient and sustainable development.

1. Data Collection: Enterprises conduct data detection and collection on fish ponds, using methods such as gravimetric estimation and sampling marking to collect data from the ponds. After sorting out, the original data fields are obtained: pond ID, stocking time, detection time, stocking quantity, survival count, cause of death, breeding cycle, person in charge, water temperature, dissolved oxygen, pH, and ammonia nitrogen.

2. Algorithm Rules: The grass carp survival rate is calculated using the following comprehensive algorithm based on the basic survival rate calculation combined with the environmental parameter correction factor (algorithm data is calculated in accordance with rounding rules):
Basic survival rate = (survival count / stocking quantity) × 100%
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: 24.0 ℃, weight: 0.30; Optimal pH value: 7.0, weight: 0.20; Optimal ammonia nitrogen value: 0.1 mg/L, weight: 0.15
Comprehensive survival rate = Basic survival rate × Environmental correction factor

3. Data Analysis: Analysis is conducted based on the comprehensive survival rate obtained from the algorithm rules. If the survival rate decreases, the pond may have abnormal environmental parameters, improper management, or disease risks, requiring timely troubleshooting of water quality issues, adjustment of breeding density, and strengthening of disease prevention and control measures. If the survival rate increases, it indicates that the breeding environment is suitable and the management measures are effective. Experience can be summarized and promoted to other ponds, and consideration can be given to appropriately increasing the breeding density to improve economic benefits.
