Rocket nets, cannon nets, and other net launching devices are built upon similar principles have been used since the 1950s (Dill and Thornsberry 1950, Hawkins ...
The company Net-works worked out a solution to turn discarded fishing nets into carpet tiles. [17] Between 2008 and 2015, the US Fishing for Energy initiative collected 2.8 million pounds of fishing gear, and in partnership with Reworld turned this into enough electricity to power 182 homes for one year by incineration.

Bottom trawling mixes these pollutants into the plankton ecology where they can move back up the food chain and into our food supply. [25] Phosphorus is often found in high concentration in soft shallow sediments. [26] Resuspending nutrient solids like these can introduce oxygen demand into the water column, and result in oxygen deficient dead ...

An animal caught in a mist net becomes entangled, so the net must be checked often and the animal removed promptly.

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]
When tangle nets are damaged beyond repair they are twisted and wrapped into long bundles, which the Philippine locals call lumen lumen nets. These long, sausage-like bundles are placed on the sea bottom along drop-offs in deep water with strong currents and left for several months at a time, which allows time for veligers to settle and larvae ...
