Trolling is a method of fishing where one or more fishing lines, baited with lures or bait fish, are drawn through the water at a consistent, low speed. This may be behind a moving boat, or by slowly winding the line in when fishing from a static position, or even sweeping the line from side-to-side, e.g. when fishing from a jetty.

In the United Kingdom the term cramp is often used instead when the tool is for temporary use for positioning components during construction and woodworking; thus a G cramp or a sash clamp ...
Electrofishing is a common scientific survey method used to sample fish populations to determine abundance, density and species composition. When performed correctly, electrofishing results in no permanent harm to the fish, which return to their natural mobility state in as little as two minutes after being caught. [1]
The razor shell, Ensis magnus, also called razor clam, razor fish[2] or spoot (colloquially), is a bivalve of the family Pharidae.

Pacific razor clams are a highly desirable shellfish species and are collected by both commercial and recreational harvesters. [5] Razor clams, like other shellfish, may accumulate dangerous levels of the marine toxin domoic acid. [6] Harvesters should check current public health recommendations by marine authorities before collecting razor clams.
Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.
A fish (pl.: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits.Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians.
