Copies of the video and CD Rom will be available for purchase during the session for an additional charge. This course is offered as an introduction to fish passage design and evaluation for engineers, biologists, and resource managers that deal with fish restoration and stream rehabilitation efforts. The objective is to give participants the necessary background to understand what is needed to design and evaluate a simple fishway. Participants will be given a list of references for additional information, design details, evaluation techniques, and operation and maintenance of fishways. Jeffrey Johnson , Senior Scientist, Smith-Root Electrofishing is an important, commonly used tool that allows biologists to collect a range of fishery data including species composition of a stream, population estimates, growth rate and others.
Improper techniques can bias results and jeopardize the plausibility of data comparison.
Electrofishing equipment produces voltages and currents that can be injurious or lethal to humans and the fish they capture. Therefore, it is extremely important that biologists learn how to operate electrofishing equipment both properly and safely. Content of the class will include the electrical theory, circuit theory, electrofishing safety and fish injury. The primary method of delivery will be through lecture and discussion facilitated with transparencies, slides, and video. Brightwater Inc. Many rivers and streams are suffering from degraded habitat.
