  • Sustainable fishing aims to maintain fish stocks at a level that allows for continuous breeding.
  • The development of large fishing vessels has led to overfishing.
  • Sustainable fishing involves not overfishing and is necessary due to the growth of big business in the fishing industry.
  • Overfishing has put species like the bluefin tuna at risk of extinction in the Mediterranean.
  • To combat overfishing, fishing quotas are implemented to limit the number of fish that can be taken from the sea.
  • Fishing quotas are not perfect as they often result in dead fish being thrown back into the sea.
  • Net size regulations help ensure that young fish can escape, mature, and breed, aiding in the recovery of fish stocks.
  • Controlled net sizes and larger holes in nets ensure that mostly larger, mature fish are caught, which have already had the chance to breed.
  • Another method to help fish stocks recover is banning fishing during the breeding season, allowing fish to breed and increase their numbers for future years.
