Abstract
A fish bait intended mainly for use in long line fishing is constituted by a natural bait material, such as fish, squid, shellfish, fish offal, dehydrated or freeze dried fish meal and/or fish oil (3) enclosed in a porous casing (1,2). The casing, which surrounds the entire bait, is made of a layer of semi-permeable membrane (1) and a layer of mesh reinforcement (2). The membrane preferably is a collagen based material which allows fish oil and aroma constituents of the natural bait (3) to permeate into the surrounding water to attract fish. The reinforcing mesh, which preferably is made from a knitted cotton tubular bandage material, provides stability for the bait package, and ensures that the bait package is retained on a hook (5).
