• Aquaculture: raising fish or other aquatic species in cages/enclosures underwater
• Aquaculture benefits:

  • Requires only a small amount of water, space, fuel
  • Reduces risk of fishery collapse
  • Doesn't take up land space (compared to beef, pork, chicken)
• Aquaculture drawbacks:

  • High density produces high concentration of waste --> risks of eutrophication
  • High density increases disease risk, which can be transmitted to wild populations as well
  • May introduce non-native species or GMOs to a local ecosystem if captive fish escape
  • Fish are fed antibiotics which can contaminate water
