“…In many fisheries small boats are more efficient than large ones and contribute more to social welfare because they employ more people per fish sold, supporting numerous small-scale livelihoods (Nikoloyuk and Adler 2013;Sabau 2013), and they have a more beneficial ratio of input to output than larger boats (Pinkerton 1987 Copes (1986) predicted, in fisheries where larger fish fetch higher prices, a fisherman with a fixed quota has incentives to discard smaller fish, thereby "high-grading" to get the greatest possible value out of the same number of fish taken. The Faroe Islands passed a ban on discarding fish in 1994, but the state could not prevent it under the ITQ system (Gezelius 2008 (Symes et al 2003;van Hoof 2010;Emery et al 2012). Many countries have learned that, instead of being a substitute for input controls such as gear, area, and time regulations, ITQs (output controls) require input controls to work, and many countries have had to add them over time.…”
