Unfortunately‚ long-liners often catch several times as many sharks than they do tuna. Until relatively recently‚ this shark ’bycatch’ was considered a nuisance‚ and sharks were cut loose and allowed to swim away

Shark Finning It wouldn’t be news if I told you our planet has its environmental problems. We’re making some progress in controlling what we put into the air‚ put into our landfills and even put into our oceans.

That number refers to the number being killed only for their fins and almost entirely to make shark fin soup. You may not really care

Sharks and Australian Fisheries The Fishing industry is the 5th largest food producing industry in Australia. Annually it puts $2.2 billion dollars into our economy each year (afma.gov‚ 2013). Australians consume approximately 16kg of fish and seafood per person per year. This amounts to a lot of fish needed to sustain such a demanding population.
