Between 177 and 180 the Greek author Oppian wrote the Halieutica, a didactic poem about fishing. He described various means of fishing including the use of nets cast from boats. In Norse mythology the sea giantess Rán cast a fishing net to trap lost sailors. [8] There is a reference in the New Testament to cast netting. Per John 21:6: "He said ...
When using pulsed DC for fishing, the pulse rate and the intensity of the electric field strongly influence the size and nature of the catch. The conductivity of the water influences the shape and extent of the electric field and thus affects the field's ability to induce capture-prone behavior in the fish. It can also cause injury to the fish.
In the 19th century, luminiferous aether (or ether), meaning light-bearing aether, was a theorized medium for the propagation of light. James Clerk Maxwell developed a model to explain electric and magnetic phenomena using the aether, a model that led to what are now called Maxwell's equations and the understanding that light is an ...
A highly simplified version of fish corrals is the tagbacoe, which do not have playgrounds. Instead it consists of V-shaped "wings" that lead directly into the bunt. Tagbacoe are generally lit at night to attract fish and crustaceans and do not rely on tides. [19] [26] [27] [23] Fish nest
Gillnetting was an early fishing technology in colonial America, [vague] used for example, in fisheries for Atlantic salmon and shad. [10] Immigrant fishermen from northern Europe and the Mediterranean brought a number of different adaptations of the technology from their respective homelands with them to the rapidly expanding salmon fisheries ...

This is the earliest such work to have survived intact. Oppian describes various means of fishing including the use of spears and tridents. [3] In a parody of fishing, a type of gladiator called retiarius carried a trident and a casting-net. He fought the murmillo, who carried a short sword and a helmet with the image of a fish on the front. [4]
Midwater (pelagic) trawling is a much "cleaner" method of fishing, in that the catch usually consists of just one species and does not physically damage the sea bottom. However, environmental groups have raised concerns that this fishing practice may be responsible for significant volumes of by-catch, particularly cetaceans (dolphins, porpoises ...
