Gillnetting is a fishing method that uses gillnets: vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water. The floats are sometimes called "corks" and the line with corks is generally referred to as a "cork line."
Drift netting is a fishing technique where nets, called drift nets, hang vertically in the water column without being anchored to the bottom. The nets are kept vertical in the water by floats attached to a rope along the top of the net and weights attached to another rope along the bottom of the net. [ 1 ]

They are normally set at dusk and hauled in at dawn. Drift gillnetting is commonly used on Lake Albert, but rarely on other water bodies. The target fish species for the gillnet fishery are Nile perch, tilapia, Bagrus, Clarias, Protopterus, Alestes, Hydrocynus and many other demersal fish. Fish nets have different sizes.
Seine nets can be deployed from the shore as a beach seine, or from a boat. Boats deploying seine nets are known as seiners. Two main types of seine net are deployed from seiners: purse seines and Danish seines. A seine differs from a gillnet, in that a seine encloses fish, where a gillnet directly snares fish.
Netting is the principal method of commercial fishing, though longlining, trolling, dredging and traps are also used.
