Capture carbon, not krill?

This week the Changing Markets Foundation has called for?a moratorium on the Antarctic krill fishery?– which processes the crustaceans into salmon feeds and health supplements. The fishery may regularly top sustainability tables – as less than one percent of the biomass is harvested each year – and Changing Markets does have form when it comes to anti-aquaculture hyperbole, but they do bring up some interesting points.

Capturing krill may not only impact the extraordinary fauna of the Antarctic ecosystem but may also accelerate climate change by preventing the carbon stored in the crustaceans from settling in the depths of the ocean when they die. While many will see the report as scaremongering, it’s an argument that is gaining ground in more sober, scientific circles and one argued more subtly and persuasively in Charles Clover’s thought-provoking new book,?Rewilding the Sea.
