Production of soft-shell crabs is year-round, and exports of the crabs are mostly frozen. However, there are no-fishing seasons for the species in some countries which may affect access to live animals.
Hook and line is one of the best methods of fishing with regards to sustainability. This can involve one person and a rod, or alternatively using a basic winch with a line of hooks. The hook and line fishing method has little impact on the surrounding environment and the catch can be selective. For example, any fish too small, or not the right species can be placed back into the water, with limited harm.
Traps and pots made of wood, metal wire or plastic are placed on the seaﬂoor to catch fish, sometimes by using bait. The captured animals are usually still alive in the traps and pots when they are harvested. Traps and post are commonly used to catch lobsters and crabs.
