New study shows high mortality rate of mako sharks
A paper published in the journal Proceedings of the Royal Society B shows that the fishing mortality rate for shortfin mako shark (Isurus oxyrinchus) is significantly higher than has been thought. Researchers found that 30 to 40% of satellite tagged sharks were being captured in fisheries, which when extrapolated, means that the number being killed is 10 times higher than previously believed.
