| 溯源编码与标识技术是全程质量控制技术的关键，参照EAN·UCC全球统一标识系统，通过研究EAN/UCC-13码和EAN/UCC-128码，建立了基于EAN/UCC-128编码方式的鲆鲽类产地溯源的编码方案；在研究确定标签材料的基础上，通过比较研究尾部捆扎、不同部位嵌挂等不同标识方法，建立了单尾标签标识技术，系统的建立了产地标识方法，为鲆鲽类产品进行产地追溯提供了技术支持。该方法可借助电子信息技术，实现养殖到消费终端的全程可追溯。研究和示范结果表明，标识标签脱落率小于2%，标签浸泡30 d条码信息识别准确率可达到近100%。 |

| Abstract: |
| Traceability coding method and identification technology is the key step for the total quality control. According to EAN·UCC-the Global Identification System, this study established the coding method for flounder traceability based on UCC/EAN-128 Bar Code by comparing UCC/EAN-13 to UCC/EAN-128. After the label material was determined, the label was linked to each fish by strapping the label on the fishtail or embedding on different parts of the fish, and after comparison an identification method of flounder traceability was established. This method could provide technical support for flounder traceability and ensure the total traceability from breeding to consumption with electronic information technology. The research and demonstration results indicate that the label abscission rate is less than 2%, and after the labels being soaked for one month, the recognition accuracy of bar code information reached 100%. |
