reducing fishing impacts

Cards (12)

  • Management:
    • Catch quotas 
    • Net design 
    • Restricted fishing 
    • No take zones 
    • Minimum catch size 
    • Maximum catch size 
    • Captive rearing and release 
    • Biodegradable equipment to reduce ghost fishing 
  • Total allowable catch - EU waters, shared between EU countries as quotas. 
    • Legal upper limits 
    • Species specific 
    • All fish landings documented 
    • Fines 
  • Mesh nets are made of diamond mesh that closed under tension. Some contain escape hatches and acoustic deterrents. 
  • The number and size of boats and nets is restricted, the number of days at sea is also controlled. 
  • No take zones are areas with bans on fishing, allowing breeding by legally designating areas of conservation - exclusion zones. 
  • Closed seasons are bans on fishing during particular times of the year - salmon 14th feb ---> 30th sep. 
  • Minimum catch sizes allow greater recruitment (biomass) before capture. Undersized fish are returned and minimum net sizes. Only works if length correlates with sexual maturity. 
  • Population seeding is when young fish are raised and released to be later caught. 
  • Biodegradable nets mean that there is less chance of any lost nets ghost fishing.  
  • Streamers deter seabirds from baited hooks - albatross
  • Setting lines at night reduces birds caught. 
  • Pole and line fishing is very specific so little bycatch and carried out by local people.
