Introduction

The Department of Ecology has been checking the population and migration patterns of fish in the Smith River. Radio Frequency Identification (RFID) tags are implanted into fish swimming in the river which communicate with various antennae spread out across the system. The antennae transmit data to the RFID reader stations such that the location and frequency of fish at a particular point along the river can be recorded. The Department of Ecology currently uses a system, known as the gray box, produced by Oregon RFID™ which exhibits a large number of problems.

The Oregon RFID™ Feild Unit (gray box) is incredibly restrictive in terms of user interface. The data feed produced is inaccessible without physically visiting the RFID reader sights. This is a tremendous problem considering the very remote locations of the RFID readers. Additionally, the RFID data feed can only be accessed by opening the box containing the RFID circuitry exposing the internal components to water from the river and increasing the risk of contamination. The data feed format is incredibly unusable as the putty database where it arrives is not easily manipulated and must be copied into a more usable program such as excel.
This is the second consecutive year in the which the MSU Fish RFID project has been assigned. A proposed solution, known as the orange box, was created last year and is the basis for the approach of this year’s project. The orange box has advantages over the gray box such as an improved user interface and the addition of a lightning surge arrester and utilized similar technology to read the RFID tags. There are issues with the orange box that will be addressed in this year’s project. The user interface enhancements must be completed including the ability to convert the data feed into a usable format such as a .csv file and grant remote access to some of the more inconvenient locations. The RFID reader also most include an additional antenna such that both fish populations and movements can be recorded by the system for better population assessments by the department of ecology. By the end of the academic year, the MSU Fish RFID project will achieve these enhancements and provide an improved replacement for the current RFID reading system.

Motivation

The main goal for the MSU Fish RFID project is to provide an improved alternative the fish tracking system currently used by the Department of Ecology. The department has issued concerns over the usefulness of the RFID reader used to track the population of fish on various points on the Smith River. The ability to track and monitor the populations of fish is especially important in a state like Montana where outdoor activities are a major component of its culture. Monitoring through the RFID system is important to provide assistance to responsible involvement with the environment ensuring that recreational activities are still possible while the ecology is in no way threatened unnecessarily.

From a technical perspective, the MSU Fish RFID project is an opportunity to incorporate technical design with an actual client. The project requires design elements in power efficiency, communication design, and software design. The power implementation design is to be performed in order to ensure that the RFID tags can be efficiently read and the antennas sufficiently powered while minimizing losses due to noise and unnecessary power draw. The communication design will be performed in order to create a signal that can accurately respond to the tags implemented within the fish and to have multiple antennas receive signals without interference. The software design is to be implemented to create a system where the data feed is easily attainable and the data is clear and usable. The RFID project ensures technical advances and design experience while simultaneously contributing to the expansive outdoor experiences available in Montana.

Sponsor Information

Michael Lance | Department of Ecology

The sponsor for the MSU Fish RFID project is Michael Lance of the Department of Ecology. Mike researches fish population and movement in the Smith River monitoring the ecological stability of the region. The reader stations are located in numerous locations, many of which are in relatively inaccessible regions requiring multiple day trips in order to access the data. Mike has requested the redesign of the RFID readers in order to simplify the process of obtaining data while simultaneously enhancing the data feed. It has been specifically requested that the new design incorporate multiple antennas in order to monitor fish movements as well as populations. It has also been requested that the main focus on the project is to enhance the user interface of the system. Michael Lance effectively has the main authority in stipulating the constraints and goals of the project
