New research on fishing and catch rates has shown we may have reached Peak Fish. We have removed 90% of the larger predator fish from the oceans, according to results presented at the AAAS meeting in February 2011. Future fish populations will be dominated by small fish. This affects economies and diets worldwide.
It has even caused an increased prevalence of pirates in the vicinity of certain countries whose fishing industry has collapsed.

OVERFISHING is catching too many fish (or prawns etc.) so these animals cannot sustain their population. The fish get fewer and fewer, until finally there are none to catch.
Overfishing is a threat to marine biodiversity, and it is changing evolution.
If you eat seafood, make sure you know what you eat and try to pick the ones with the lowest impact.

A good choice of fish to buy might be Threadfin Tuna
for reasons that include:
- good populations available
- fast-growing species
- they breed early
- under fishing pressure they spawn even earlier
- they’re netted away from dugong areas
