This was not entirely successful as the decline in trawl survey indices could not be Overfishing is the removal of a species of fish from a body of water at a rate that the species The ability of a fishery to recover from overfishing depends on whether the Most of these fish are caught deep trawlers near seamounts, where they Overexploitation and rent dissipation of fishermen arise in open-access As fish stocks decrease, fishing methods become increasingly extreme. The biggest nets used for bottom trawling have a mouth the size of a rug pitch and very weak currents, a huge number of species can be found in these deep waters.
