[1][2] Ancient methods of preserving fish included drying, salting, pickling and smoking.

Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode. This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned.
