The ABC Science Show's Robyn Williams talks global fish stocks with three fisheries scientists.
The oceans will be populated by small fish. Large predatory fish will be gone. Over the last 100 years large predatory fish have declined by 2/3. More than half the decline has occurred in the last 40 years. Higher temperatures will lead to lower production and less fish. The demand for fish is increasing but the supply is not. Fishing effort has increased each year since the 1950s, but recently the catch has not increased. Have we reached 'peak fish'?
