Fishing sinker

A sinker assembly configured to be coupled to a fishing line, the sinker assembly comprising:

• a sinker comprising:
• a body having a first end portion, a second end portion opposite the first end portion, and a main body portion connecting the first and second end portions, the body being constructed of a material with a first galvanic corrosion potential in salt water,
• an abutment structure positioned adjacent to the first end portion, and
• a line receiving channel extending along a longitudinal axis of the body between the first end portion and the second end portion;
• and
• a sleeve removably coupled to the body of the sinker, the sleeve comprising:
• a body portion defining a receiving aperture that is sized to receive the body of the sinker, the body portion of the sleeve engages the abutment structure of the sinker to selectively secure the sleeve to the sinker, the body portion being formed of a material with a second galvanic corrosion potential in the salt water that is different from the first galvanic corrosion potential,
• wherein the difference between the first galvanic corrosion potential of the sinker and the second galvanic corrosion potential of the sleeve results in a voltage gradient in the salt water that stimulates an electrosensory system of an electrosensitive organism in the salt water.

A sinker configured to be coupled to a fishing line, the sinker comprising:

• a body having a first end portion, a second end portion opposite the first end portion, and a main body portion connecting the first end portion and the second end portion;
• a longitudinal axis extending centrally through the first end portion and the second end portion;
• a line receiving channel extending along the longitudinal axis between the first and second end portions;
• and
• a series of cutout portions defined in the body and in communication with the line receiving channel,
• wherein the series of cutout portions are configured to receive the fishing line to allow for quick attachment and detachment of the sinker to the fishing line.
