Biodiversity and Conservation

• Food from the Sea
• The problem and possible solutions

OVERFISHING

• Causes economic, ecological and social disasters
• Ecologically Overfishing causes populations of
  many marine organisms to be reduced drastically
  and in some cases to the edge of extinction. Fish
  is part of the food chains and webs of the seas
  and any uncontrolled harvest have a negative
  effect on other species

• Economically overfishing reduces the population
  of certain species. After extensive overfishing
  there will be too little fish in the sea, and
  fishermen who depend on this industry for their
  living will find themselves jobless.

4

• Socially Some societies depend mostly on
  fishing as a way of life, they live near the sea,
  they work at the sea and their entire life
  support comes from the sea.

HOW CAN OVERFISHING BE PREVENTED?

• Reducing the limits of annual total catch
• enforcing a quota for the number or weight
  of fish that can be caught
• Controlling and regulating mesh size
• Allows the fish to grow to a certain size
  before it is caught and allows it to reproduce
  and increase its P before capture
• Limiting the areas of fishing and claiming some
  areas out of bound
• Allows fish to reproduce and pick up their
  in prohibited areas

6

• Enforcing close seasons
• Seasons when fishing is not allowed to help
  restore fish populations during spawning and
  growth seasons
• Fish farming
• To satisfy the demands for food
