A castable object is described. In some embodiments, a castable object includes: a structure including a first distal end and a second distal end; a fastener coupled to the first distal end, where the fastener is configured to couple to a fishing system; and a first fastening surface attached to at least the second distal end, where the castable object is configured to be cast by the fishing system onto a target, and where the first fastening surface is configured to removably attach to a second fastening surface of the target.

A lure includes a first and second body parts, a structure in which the first and second body parts are coupled together, and an interior cavity, and a rod bridging the first and second body parts in the interior cavity. The rod has a rod portion, a flange portion connected to a first end of the rod portion, and a projecting portion projecting from the flange portion to an opposite side of the rod portion. The first body part has an inner surface and a rod hole on the inner surface thereof. The second body part has an inner surface and a base projecting from the inner surface thereof, and a receiving hole recessed from the surface of the base. A second end of the rod portion is inserted into the rod hole, the projecting portion inserted into the receiving hole, and the flange portion in contact with the base.

A link fishing lure system may provide an interchangeable lure that may be used in many fishing conditions. The link fishing lure system may contain an enclosure with a channel that may house a connecting link. The link fishing lure system may contain the connecting link within the channel. The connecting link of the link fishing lure system may be secured within the channel when an attachment is coupled to the connecting link. The link fishing lure system may contain an eye canal that extends through the enclosure, intersects the channel, and is operable to house an eye capsule. The eye capsule of the link fishing lure system may be secured within the eye canal when the connecting link is secured within the channel. The link fishing lure system may contain a weighting compartment. The connecting link of the link fishing lure system may be slidably moveable within the channel.

A fish attractant dispersal apparatus may comprise a dispersal pouch encompassing fish attractant. The dispersal pouch may comprise a water-soluble material configured to dissolve in water to release the fish attractant. The dispersal pouch may define an attractant cavity configured to encompass and seal the fish attractant. The attractant cavity may be sealed to at least partially reduce air trapped within the attractant cavity. The attractant cavity may be sealed to remove air within the attractant cavity.

A sonic stimulation and detection device includes an enclosure mounted on a fishing rod having to a fishing line attached to and extending along the rod. A microphone element is mounted in the enclosure and is acoustically coupled to the line through the enclosure and the rod line to couple sounds of fish contact with the line to the microphone. The microphone may be coupled to a headphone. A sound generator is mounted in the enclosure and is acoustically coupled to the line through the enclosure and the rod to couple fish simulating sounds generated thereby to the line to attract fish to a lure attached to the line. The enclosure is shaped to efficiently couple sounds coupled from the line to the microphone and sounds generated by the sound generator to the line.

A process where materials are applied to a plastic fishing lure surface, producing a lure that possesses chromatic vicissitude as a result of water temperature fluctuations. A non-thermochromatic base layer of one or more colors is applied to the plastic fishing lure. This layer acts as the visual appearance of the fishing lure in the absence of temperature fluctuations. Clear extender is then used as an additive to the thermochromatic ink. This addition to the ink then allows the ink to be sprayed onto the surface of the lure. This ink-extender amalgam can be applied in multiple layers however the bottom layer must have the least amount of hue saturation. Each layer thereafter would increase in hue saturation. Multiple hue combinations can be utilized. Once the desired number of thermochromatic layers has been applied, an ultra-clear super high gloss lacquer finish is sprayed on to the exterior of all layers.
