Tools of the Trade

As technology continues to evolve in biological sciences and research fields, monitoring tools are becoming increasingly effective. Equipment such as high definition underwater video cameras, sonar devices, acoustic receivers, infrared scanners and much more are proven fisheries science instruments that can all be incorporated into weir structures. By coupling one or more of these monitoring tools with a resistance board weir you have many options to gather more precise and varied data.

Cramer Fish Sciences' biologists have years of experience with these varied technologies and approaches; specifically, our staff has an intimate working knowledge of the Vaki RiverWatcher fish counter and monitoring system. The RiverWatcher, which combines infrared scanning technology with an underwater digital camera, produces paired silhouette images and digital photos. Data collected at the Stanislaus River weir project illustrates the effectiveness of combining monitoring technology with a weir, and Dr. Merz's research demonstrates the utility of silhouette data (click here to read his paper).
