Species has a combination of problems such as overfishing, high bycatch, and poor management.
Crab, Blue and Red Swimmer – East and South East Asia

Swimmer Crabs grow quickly, reach sexual maturity around age one, and live for three years. They are caught in a number of countries in the Indian Ocean and Western Central Pacific.

In China, India, Indonesia, Vietnam, and the Philippines there is very limited management in place for Swimmer Crabs and abundance levels are uncertain.

Each country uses a mixture of gear types to catch Swimmer Crabs. Pot fisheries have minor affects on non-target species, while trawl and gillnet fisheries have high impacts because of the potential to catch marine mammals, sharks and endangered sea turtles.
