Eco details:
Most shark species are severely depleted. The main reasons for their precipitous decline are:
- They are caught accidentally by the thousands and discarded as waste by tuna and swordfish longline fishers.
- There is strong demand for their fins in Asia.
- Most sharks mature slowly and have few offspring.
Spiny dogfish are especially vulnerable to overfishing, since they have the longest gestation period of any vertebrate (two years).
