Fringe Benefits of Global Warming

The tuna industry says climate change is bringing benefits.

The chief executive of the Australian Southern Bluefin Tuna Association, Brian Jeffriess, says Port Lincoln crews in South Australia are reporting an excellent quality and size catch.

He says it can be partly attributed to the effects of climate change on the waters of the Great Australian Bight.

"There's no doubt climate change will bring benefits to the Great Australian Bight ecology in the sense that there's more upwellings therefore more small pelagics as we call them - sardines, mackerel, red bait, other fish - and that will bring tuna so there may be even winners from climate change," he said.

"This year some of the oceanographers are saying they've never seen south-easterly winds in a sustained strong way now that creates a lot of upwellings in the water - that brings nutrients to the surface.

"There's a feed chain which feeds on those - the tuna is virtually the last part of that food chain and benefits from improvements in the other parts of the food chain."

Thats all well and good, until we suffer the revenge of the giant squid
Australian scientists say global warming is turning the world's squid into much larger creatures, with huge appetites and fast breeding cycles.

Scientists have discovered the breeding cycle and growth rate of squid is linked to sea temperatures, which means global warming is causing the squid population to blow out.

Scientists say that they have found that a 1 per cent increase in water temperature causes juvenile squid to double in size.

Dr George Jackson, from the Institute of Antarctic and Southern Ocean Studies, says scientists are expecting to see more overgrown squid, like the giant squid recently found in Tasmania.

"The body alone was not far under two metres in length and it took about four people to actually turn it over when we wanted to look at the underside," he said.

Dr Jackson says squid are moving into regions where heavy over-fishing has left them with no natural competitors.

"If places have been overfished or the squid have been removed, squids have often moved into those areas and established themselves very quickly," he said.

Global warming is all tuna steaks and calamari.
