sign of rapid change is that stories like this are coming out in the
New Zealand media. A big change from zero-coverage
NZ:Warmer
seas 'will change fishing industry'
A
fisheries expert believes warming sea temperatures will change the
way the industry looks in years to come.

April, 2014
One
of the country's biggest fisheries companies, Sanford, has closed its
Christchurch mussel processing factory, blaming rising ocean
temperatures for cutting the mussel yield in the upper South Island.
Temperatures
in the Tasman have already risen one and a half degrees in the past
70 years.
And
experts believe temperatures off the Southland coast could rise by up
to 2 degrees.
A
marine biologist at Victoria University Matthew Dunn said if
temperatures continued to increase the industry would need to adapt.
"If
things get warmer you might expect that whole distribution to shift,
so we've seen more warm water stuff coming down and more cold water
stuff disappearing. The cold water stuff includes some of the big
ones, that's hoki, and hake and ling and squid," he said.
"So
the message for the industry or message for someone investing in this
is don't put all your eggs in one basket."
He
said more research was needed to be done to fully understand the
changes.
