Optimize the Autonomous Sensor Fish Device for Understanding Interactions of Aquatic Animals with Marine and Hydrokinetic and Hydro Systems (CRADA 476) Final Report

Summary

This final report details the successful completion of CRADA 476, focused on optimizing autonomous sensor fish devices to understand aquatic animal interactions with marine renewable energy and hydropower systems. Completed in November 2024, the project developed three sensor variants: the Marine Sensor Fish (MSF), Sensor Fish Mini (SF Mini), and Flexible Sensor Fish (FSF), under U.S. Department of Energy Contract No. DE-AC05-76RL01830. These devices are capable of measuring critical environmental stressors like shear forces, pressure changes, and strike impacts. Field testing at sites such as Sequim Bay, Washington, yielded high-resolution data that supports fish-friendly design improvements and validated computational fluid dynamics models for sustainable energy development.
