      Lesson details

      Learning outcome

      I can describe different types of fishing and explain why fish stocks are reducing.

      Key learning points

      1. Commercial fishing normally includes less sustainable methods, e.g. trawling.
      2. Longlining and trap fishing are more sustainable fishing methods.
      3. Fish farming, or aquaculture, is the controlled breeding and harvesting of fish in enclosures.
      4. In 2018 nearly 90% of the world’s marine (sea) fish stocks were fully exploited, overexploited or depleted.
      5. Overfishing, bycatch and marine habitat damage are some of the concerns associated with fishing.

      Keywords

      • Commercial - related to the making of money from buying or selling things

      • Sustainable - able to continue over a long time

      • Exploit - to use something for personal benefit

      • Depleted - used up or nearly all gone

      • Habitat - the natural home or environment of an animal, plant or other organism

      Common misconception

      There are plenty more fish in the sea.

      In 2018, nearly 90% of the world’s marine (sea) fish stocks were fully exploited, overexploited or depleted.

      Teacher tip

      A potential homework could be to research water quality and fish stocks in the local area.
