Shrinking fish more vulnerable to predators  Updated March 25,
2013 13:14:00  CSIRO researchers found that shrinking fish sizes
due to climate change and fishing maybe making them more
vulnerable to natural predators. This would affect their long
term recovery even if fishing quotas were reduced and marine
reserves were established.  Source: PM | Duration: 3min 32sec

SALLY SARA: A new study by the CSIRO (Commonwealth Scientific
and Industrial Research Organisation) shows that fish around the
world are shrinking in size.  Commercial fishing and climate
change are believed to be the main culprits behind the decrease,
but CSIRO scientists say the shrinking size is also leading to a
drop in fish populations, with smaller fish more susceptible to
predators.  Jennifer Macey reports.  JENNIFER MACEY: Scientists
at the CSIRO have found that the shrinking size of fish may be
making them more vulnerable to predators.  Dr Asta Audzijonyte,
