This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned.
Fishing techniques include hand-gathering, spearfishing, netting, angling and trapping. Recreational, commercial and artisanal fishers use different techniques, and also, sometimes, the same techniques. Recreational fishers fish for pleasure or sport, while commercial fishers fish for profit.

Sea water flake ice machine can make ice directly from the seawater. This ice can be used in the fast cooling of fish and other sea products. The fishing industry is the largest user of flake ice machines. Flake ice can lower the temperature of cleaning water and sea products, therefore it resists the growth of bacteria and keeps the seafood fresh.
Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. [2] Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems.
