| Electrofishing | ||
| One of the key tools available to fishery management is that of electrofishing. |
| The main purposes of electrofishing are stock assessment, sampling/health surveys, tagging, catching spawners, anaesthetising or eliminating species. | ||
| Electrofishing is an effective tool for fishery management because most aquatic organisms become motionless when the body voltage exceeds a certain value from nose to tail. | ||
| A field of electricity is passed through the water which in turn causes a muscle response reaction from the fish forcing them toward the netsmen. |
