To minimize accidental capture of marine animals, National Oceanic and Atmospheric Administration (NOAA) fisheries developed and tested bycatch reduction devices (BRDs). ). These devices are openings in shrimp trawl nets that allow finfish or other unwanted aquatic animals to escape, while the target species, shrimp, is directed towards the tail bag or cod end of th
In Japan, fishermen use drifting rafts of bamboo bundles to attract mahi-mahi, which are then caught by encircling nets. In Malta, a very similar method (known as kannizzati) is also used to catch mahi-mahi and pilot fish, using anchored flat cork rafts that are then harvested by encircling nets, long lines, or trolling.

Fishing nets, cod traps, and sails would be dipped into a barking pot filled with a solution of bark and other materials. [5] The use of bark mixtures for the preservation of nets was brought over by English migrant fishermen during the 17th century; Aaron Thomas described the vessel used for making this bark mixture in his 1794-1795 journal of ...
A seine is a large fishing net that may be arranged in a number of different ways. In purse seine fishing the net hangs vertically in the water by attaching weights along the bottom edge and floats along the top. A simple and commonly used fishing technique is with beach seine, where the seine net is operated from the shore.
During this process, live fish in nets must be transferred to clean pens, which causes undue stress and asphyxiation that results in some loss of fish. [37] Biofouled nets that can be reused are washed on land via manual brushing and scrubbing or high-pressure water hosing. They are then dried and re-impregnated with antifouling coatings.
A fisherman repairs a gillnet (April 1973, St. Helens, Oregon) In 1931, the first powered drum was created by Laurie Jarelainen. [citation needed] The drum is a circular device that is set to the side of the boat and draws in the nets. The powered drum allowed the nets to be drawn in much faster and along with the faster gas powered boats ...
This is the heartwarming moment fishermen cut loose a turtle that was tangled in a loose net. Anucha Boontaeng, 42, noticed the turtle struggling as it floated in loose nets in the Andaman sea ...
Lift nets - are a method of fishing using nets that are submerged to a certain depth and then lifted out of the water vertically. The nets can be flat or shaped like a bag, a rectangle, a pyramid, or a cone. Lift nets can be hand-operated, boat-operated, or shore-operated. They typically use bait or a light-source as a fish-attractor. [14]
