Electrofishing saves fish population

September 30, 2012 by  

Who would have thought that sending an electrical charge into a lake, river or ocean would actually save aquatic life rather than destroy it? Yet, electrofishing actually helps the conservation efforts of the Oregon Department of Fish and Wildlife instead of wreaking havoc.

Electrofishing is one of the latest technological advances used by marine biologists in Coos Bay to assist with monitoring and amending fish populations. It requires the use of a specialized boat well-equipped for the task. A machine with generators sends an electric shock into the water that attracts fish to the boat and stuns them at the same time. Biologists can then net the fish for sampling, assessing, measuring and analyzing the fish population. Removal of non-native and unwanted species can also be done.

The system works particularly well for certain species of fish, including bass. Sampling is usually done at night since the bigger fish come closer to the surface.

As new technology such as electrofishing comes onto the market, printing companies can work together with manufacturers to create top notch promotional material to advertise the benefits of the system. Flyer printing and poster printing are great tools to describe and illustrate new technology. Brochure printers can also contribute.

Besides Coos Bay, the electrofishing boat currently is used in other southern Oregon water bodies, such as Empire, Butterfield and Eel lakes. Most electrofishing is done in the fall and spring months when the Oregon Department of Fish and Wildlife is actively monitoring the quality and quantity of fish populations.
