Animal RFID Tags Recognition Based on RFID Technology
Scientific fishery management requires providing abundant biological information about fish, such as activity patterns, seasonal migrations, population size, survival/mortality rates, etc. Common types of fish tags include: RFID tags, T-bar tags, acoustic tags, fluorescent tags, satellite tags.
RFID tagging is widely used in fish stocking, aquaculture, and other aspects due to its long validity period, difficulty to be damaged after implantation into the fish body, non-contact identification, fast reading speed, and good environmental adaptability. It is a reliable and effective monitoring method that can identify and collect information on fish without manual intervention, helping to track and monitor valuable species.
The Functions of Using Fish RFID Tags
- Real-time recording and uploading of fish data sensed, avoiding the need for relevant personnel to spend a lot of time on data processing, and accurately counting the number of fish passing through.
- Conduct quantitative analysis of fish tracks through collected data, timely grasp fish activity patterns and seasonal migrations, and provide important bases for scientifically judging migration times, fish behavior tracking, population assessment, ecological environment restoration, etc.
- Facilitate the future scientific identification and differentiation between artificially stocked fish and naturally bred fish.
- Facilitate the study of the entire life history of fish, improving the effectiveness of fishery production and resource conservation management. By injecting and implanting RFID tags into the fish, each fish has a unique ID, and the RFID tag code is bound to the fish as its identity identifier. Using RFID tag readers to collect fish RFID tag information, thereby determining the growth status, population size, activity area, etc., of the fish, achieving individual identification and tracking of fish, and used for studying fish behavior patterns.
Fish RFID tags comply with the international standards ISO11784/11785, are only the size of a grain of rice, and have passive (no power supply required), non-toxic, and anti-detachment characteristics. They have a long service life and can exist in the fish’s body for life without any behavioral impact on the fish after implantation.
RFID tag readers use wireless reading methods to read fish RFID tag information. The readers support USB and Bluetooth two communication interfaces, have a bright OLED display, 2W large-capacity data storage, and support multiple languages for free switching, making data collection and information reading more convenient and faster.
For example, in the Chinese sturgeon stocking activity, the stocked Chinese sturgeons were implanted with RFID tags as their “ID cards.” Subsequently, by scanning with an RFID tag reader, information such as their birth time, breeding unit, fry batch, and stocking time can be accessed. When the RFID tag is captured at certain time points, a location information can be obtained at each different time point, thereby calculating the activity space, swimming speed, population structure, etc., of the Chinese sturgeon, helping to establish a complete tracking system for the growth, reproduction, and migration of Chinese sturgeon, facilitating later individual tracing and evaluating the stocking effect.
