A method of line fishing, includes handling of fishing hooks (16, 116) relative to fishing lines (15), especially on board fishing vessel (10). Provision is made for each fishing hook (16, 116), during drawing in of fishing line (15) with associated catch fastened to the fishing hook (16, 116) and particularly with specially occurring, especially high tractive forces, to be broken in pieces at a definite fracture location instead of being deformed. The fracture location is fixed at a weakened, local position in the fishing hook. The local position defines a moment arm (116') in the hook (16, 116) relative to a definite traction loading position in the hook. A fishing hook (116) for use in connection with line fishing, is designed for mechanical handling on board a fishing vessel (10). The fishing hook (116) is made of material rigid to bending and is designed at a definite location (at 116a) in the fishing hook with a weakened hook cross section for directing a possible fracture of the fishing hook to the definite location (at 116a) in the fishing hook (116).

A fish hook (10) comprising: a hook portion (11); a shank (12) extending from the hook portion (11); and a line attachment portion (13) to engage a fishing line (17) to secure the fishing line (17) to the hook (10), said attachment portion (13) comprising a pair of legs (14, 15) which extend to a junction, with one of the legs (14, 15) having a free end (16) and the other leg being a continuation of the shank (12), said legs (14, 15) each having a line engagement portion (33), with the line engagement portions (33) being spaced by a distance of at least one time the diameter of the fishing line (17). A knot to secure the hook (10) and a method of forming it is also disclosed.

A fish hook (2) of the invention includes a J-shaped shank (4). The shank (4) has a point (6) at its one end for hooking a fish and a flattened joint (10) at the opposite end where a fishing line is fastened to. The joint (10) has a slit (12) extending from its edge. In fastening, a fishing line is firstly positioned in the slit (12), secondly wound around the shank (4), and finally positioned in the slit (12) again.
