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