The present invention relates to a fish hook settler for longline fishing, which comprises a plate body. The three corners on the surface of the plate body are respectively fixed with a first wire, a second wire and a third wire, and the first wire, the second wire and the third wire are together connected with a fourth wire. The first wire is shorter than the second and the third wires, and the portion of the plate body fixed with the first wire is configured with a pasture weight. The plate body will be floating in the water temporarily due to buoyancy, and then the plate body will be formed upright in the water by the pasture weight configured on one side of the plate body. Thus, by obtaining the settling force in the baiting process due to towing, the plate body will sink rapidly, and tow down the fish hook fastened on the free end of the second wire and the fish bait attached therewith.本發明係關於一種延繩釣魚鉤沉降器,包括一板體,該板體表面三角隅各固接一第一線體、第二線體與第三線體,且該第一線體、第二線體與第三線體匯接於一第四線體,該第一線體分別較該第二線體與第三線體為短,且於該第一線體固接於該板體之板體設一甸重體。藉由該板體於水中得以短暫因浮力而形成漂浮,而受該甸重體設於該板體本體偏側,會將該板體形成直立於水體中,因此在投餌過程中因拖曳而得到沉降力,使該板體急速下沉,並拖沉該第二線體自由端所繫掛之漁鉤以及所附掛之漁餌。(1)...板體(10)...甸重體(21)...第一線體(22)...第二線體(23)...第三線體(24)...第四線體(A)...沉降器
