收藏资源简介:
对象山各大黄鱼产地及养殖户基本养殖条件、养殖技术、养殖品种、生长周期、突然环境等进行数据调研,用于评估预测象山在册各大黄鱼养殖产量情况,便于针对产量告警的养殖户及时提供技术支持,确保出产大黄鱼的质量和产量,并针对质量存在问题的养殖户进行提前告警,确保产出大黄鱼的整体品质。Q= (J1+J2) x (1-0.1xwxn-0.2 xZ-0.3 xG-0.5xD)xTJ3x100 Q:大黄鱼品质评估结果,数值型; J1:大黄鱼品种外观评估结果,数值型; J2:大黄鱼品种口味评估结果,数值型; wxn:一年内违规使用药物次数,数值型; Z:水质pH值规范,0或1; G:水域水温规范,0或1; D:天气灾害发生情况,0或1; T:大黄鱼生长期,数值型; J3:是否进行过养殖结构调整,0或1; 品质分析:高品:80-100分;中品: 60-79分;低品:<60分
This dataset conducts data investigations on basic aquaculture conditions, breeding techniques, cultivated varieties, growth cycles, and abrupt environmental conditions of major large yellow croaker producing areas and farmers in Xiangshan. It is used to evaluate and predict the breeding yields of all registered large yellow croaker farms in Xiangshan, so as to provide timely technical support for farmers receiving yield warnings, ensure the quality and yield of the produced large yellow croakers, and issue early warnings to farmers with potential quality issues to guarantee the overall quality of the harvested large yellow croakers. The quality assessment formula is: Q = (J1 + J2) × (1 - 0.1 × wxn - 0.2 × Z - 0.3 × G - 0.5 × D) × T × J3 × 100 Detailed definitions of each variable are as follows: - Q: Quality assessment result of large yellow croakers, numerical type - J1: Appearance assessment result of large yellow croaker breed, numerical type - J2: Taste assessment result of large yellow croaker breed, numerical type - wxn: Number of unauthorized medication uses within one year, numerical type - Z: Compliance with water pH standard, 0 or 1 - G: Compliance with water temperature standard, 0 or 1 - D: Occurrence of weather disasters, 0 or 1 - T: Growth period of large yellow croakers, numerical type - J3: Whether aquaculture structure adjustment has been conducted, 0 or 1 Quality grading criteria: - High-quality: 80-100 points - Medium-quality: 60-79 points - Low-quality: <60 points
