When fishermen use Driftnets, they're targeting everything in the water, it does not prevent catching fishes or other species that are endangered. Sometimes, these driftnets can be a huge problem with harming species that can lead to their extinction. If there could be another form of a net that would catch the fishes.
Commercial fishing has reduced fish populations dramatically in the last 50 years since large drift nets became a viable option for catching fish in the open ocean. Hunting a particular fish species to extinction is rare. Although drift nets are detrimental to oceanic species, limits on their size and scope may help reduce overfishing as the world's human population explores more methods for consuming protein-based foods.
