Why do they fish sharks?
Nowadays, shark fishing is based on two large groups of economic activities. From one side, the big long liners and trawlers from the industrial fisheries (see also bycacth).
From other, and in a big number, it is made by artisanal fisheries all around the world. And, in both cases, the number and size of the catches have been decreasing every year.
These two groups of economic actors have different interests, incomes and motivations. But, they both know that they are fishing the last sharks.
