Australian biologists from the Department of Sustainability and Environment are electrofishing on the Murray Darling River, collecting Murray Cod and Trout Cod, taking measurements and implanting PIT tags in some then releasing them back into the river. This project is evaluating the long-term effects of replacing snags in the Murray River on these fish populations.

Updated with video of the PES™ in action.

The Portable Electroanesthesia System (PES™) allows for researchers and commercial hatcheries to effectively anesthetize fish using electricity without the withdrawal effects and disposal issues associated with the use of chemicals.

This technique eliminates the product cost of chemical agents and the associated storage fees, as well as addressing concerns with increasing regulations concerning chemical applications to aquatic species.
