Other features to simulate wounded features. Replacement fins and weighting constructions allow a user to tailor a weight and action enabling a circling or injured motion during retrieval.

Abstract: A fishing jig with a hook that has an oversized eye and a jig head that has a funnel-shaped lead-in area. The oversized eye makes it easy to insert the fishing line into the eye. The funnel-shaped lead-in area is used to guide the line directly into the eye of the hook.

Abstract: A bait assembly for fishing, e.g. leisure fishing, is described. The bait assembly comprises a hook coupled to a rearward end of a line. A bait body is slideably or detachably mounted with respect to the line so that in normal use a flexible section of the line extends into the bait body. The bait body may comprise an artificial lure, or may comprises a skewer onto which dead bait may be mounted. A retaining mechanism is arranged between the bait body and the line to bias the bait body in a forward position on the line relative to the hook. Thus when a pulling force is applied between the bait body and the line which overcomes the biasing action of the retaining mechanism, the bait body is operable to move backwards with respect to the line (e.g. by sliding or breaking free), thereby causing a relative forward translational movement of the hook with respect to the bait body.

The hook attaching device comprises an elongated member adapted to be securely received in the first hole, a stem adapted to be securely received in the first hole and an eyelet on the stem. The stem extends perpendicularly from the center of the elongated member and is substantially of the same length of the second hole. The hook attaching device is inserted in the bait; and the nose portion of the soft-bodied bait is resiliently pushed back to expose the eyelet for inserting a fish hook.

Abstract: A fishing lure capable of mimicking various motions of a wounded or distressed fish in the water. The lure may resemble a prey fish, worm or other natural food, and includes a flaccid elastomeric body having a front end, a tail end. and a tail section. The fishing lure includes a spine extending lengthwise through some, but not all, of the elastomeric body. The spine allows a fisherman to shape the lure by hand to a motion defining configuration that will cause motion that simulates that of a wounded or distressed prey fish or other natural food. The elastomeric body is not rigid enough to sustain a motion defining shape without the spine. The spine extends forward of the front end of the lure and exits the elastomeric body of the lure near the tail section, but not at the rear end of the lure. The spine does not support the tail section. The tail section is free to flutter in the water as the fishing lure is drawn through the water.
