Low-Cost RFID Fish Tracker for Local Fishery Conservation

Introducing a low-cost RFID reader for fish population studies in local fisheries, aiding conservation efforts with scalable monitoring for small streams. The system includes a Passive Integrated Transponder implanted in fish, with a dual coil half-duplex transceiver board for efficient tracking. Engineered by Nate Alix with guidance from advisor Mike Carter.

  1. SYSTEM DIAGRAM PROBLEM: State fish and game agencies have limited funds for extensive research projects that help to enhance and conserve local fisheries SOLUTION: A low – cost RFID reader will increase the fiscal feasibility of many fish population studies The antennas can be scaled up for monitoring fish in small streams RFID Fish Tracker METHOD: A Passive Integrated Transponder (PIT) is implanted in the fish READ CYCLE The transponder transmits a unique code that is received by the tuned coil and processed by the receiver Dual Coil Half – Duplex Transceiver CHARGE CYCLE SYSTEM FEATURES TRANSCEIVER BOARD • Low cost – less than $100 in components • Low power – can operate for 14 days with two marine batteries • Fast read rate – 15 cycles per second Current driven through the low impedance coil creates a magnetic field and charges the transponder Engineer: Nate Alix • Advisor: Mike Carter
