This article in the New Zealand Herald sets out in stark reality the plight of sharks.
While the article is about New Zealand waters, a parallel can be drawn in just about any fishery any where in the world.
“ Our longline tuna fishery catches twice as many blue sharks as “by-catch” as it does tuna. Ministry of Fisheries data shows that between 2003 and 2006 the proportion of tuna caught by tuna fishers was as low as 13 per cent and 18 per cent of total landed fish.
But between 22 per cent and 34 per cent of their total take was blue shark. It’s no surprise that scientists label the tuna industry the blue shark fishery.”
