Some species are well managed, others not. King, Atlantic, and Spanish mackerels have all been overfished in the past. Management has generally improved. Low to moderate in offshore purse-seine nets and coastal gill nets. Squids Many species exist worldwide, in habitats ranging from shallow bays to abyssal depths.
Squids are generally abundant, because they mature fast.
High fecundity allows them to withstand heavy fishing pressure. But the lack of management off the West Coast is raising concerns about overfishing. Low to moderate. New methods can reduce bycatch because fish behave differently from squid when encountering nets. Crabs A very large and diverse group from many regions.
