Fishing lures and lines to improve the capability of visually following an angler's lure while in the water are set forth. The lures and lines include the incorporation of materials that are sensitive to sonar imaging, and will highly define the underwater location of the fishing line on a sonar device's screen.

A trolling apparatus and method of use are provided. According to one aspect, a trolling apparatus includes a frame including an upper line guide positioned toward a rear portion of the frame and operable to engage a fishing line during a release state and a lower line guide coupled to the rear portion of the frame and operable to engage the fishing line during a retained state. The apparatus further includes a line retainer operable to be coupled to a holder aft of the lower line guide and a release mechanism operable to engage a portion of the line retainer to provide the retained state and the released state. An alternative embodiment interconnects a planar elevator between the frame and a generally upstanding planar diverter. A line retainer is formed by at least two tines and preferably by at least four tines which retain by friction a fishing line or tubular fishing line holder.

Provided are a filament having, after a water absorption treatment, a high maintenance rate of linear strength and a high maintenance rate of knot strength, and a fishing line. The filament contains a polyamide resin (A), and the polyamide resin (A) is constituted from a constituent unit derived from a diamine and a constituent unit derived from a dicarboxylic acid, and 70 mol % or more of the constituent units derived from a diamine are derived from xylylene diamine, and 70 mol % or more of the constituent units derived from a dicarboxylic acid are derived from an ,-linear aliphatic dicarboxylic acid having from 11 to 14 carbons.

An electrical transmission line cable suited for a variety of applications, including as a fishing line in a video fishing system. The electrical transmission line cable has a first conductor and a second conductor forming an electrical transmission line; a jacket containing the first conductor and the second conductor; and a transmission line primary dielectric element separating the first conductor and the second conductor, wherein the primary dielectric element is at least one of textile yarns, fiber yarns, or monofilaments. The electrical transmission line may be in a balanced configuration or an unbalanced configuration.

An elongated line device that includes an elongated core and a sheath surrounding and connected to the elongated core. The elongated core includes a polymer selected from the group consisting of a high molecular weight strain hardened polymeric matrix, a cellulose-derived fiber matrix and mixtures thereof. The sheath includes an amorphous polymeric matrix comprising cellulous ester and at least one plasticizer.

A biodegradable polymer usable in fishing gear and that biodegrades in aquatic environments. The polymer includes a polymer backbone that has monomeric units that are susceptible to hydrolytic degradation, and a plurality of pH responsive moieties. Each pH responsive moiety is grafted to a respective one of the monomeric units. The pH responsive moieties are relatively hydrophilic when exposed to an aqueous solution of a pro-biodegradation pH range to facilitate hydrolytic degradation of the monomeric units, and are relatively hydrophobic when removed from the aqueous solution of the pro-biodegradation pH range, to protect the monomeric units from hydrolytic degradation.
