APPENDIX C: ANODE RING MAINTENANCE
Make sure the Anode ring is kept clean. Anode rings will
eventually develop an oxide coating that will give the
ring a dull appearance. This coating impairs the transfer
of electricity from the electrode to the water and can be
removed with fine steel wool.
Resist the temptation to put a net on Anode rings.
Nets have the following very undesirable characteristics:
1. Nets present a safety hazard since it can place the
operator's hands unnecessarily close to the electrode
when removing fish.
2. The intensity of the electric field increases as the fish
to electrode distance decreases. Therefore, the risk of
injury to the fish is greatly increased with the use of an
Anode-ring net.
3. Nets make the Anode ring more difficult to clean.
An Anode Ring with netting
attached - never a good idea.
An Anode Ring with pronounced
oxide coating.
