Of the west Wales coast Spider Crabs is a seasonal species, which are caught by the inshore fleet of fishing vessels throughout the spring, when they migrate from deeper offshore waters in to the warmer inshore waters during the summer and autumn and the catch is of high quality with Spider Crabs being landed alive.
The fishery is a well regulated by the Welsh Government with a strict minimum size, which is a larger minimum size than the European requirement to insure the fishery is sustainable for future generations.
All fishing is carried out by low impact sustainable fishing methods, with a natural open ranching mechanism, where Spider Crab are caught in baited pots, or nets, Spider Crabs are measured and all undersize/non target species are returned unharmed to the sea.
Spider Crabs are stored in storage pots and landed daily or weekly as markets demand.
The fishing industry within west Wales coast is mostly made up of small fishing vessels under 10 metres in length, which have the time they can spend at sea limited by strong tides and Atlantic weather systems which also acts as a natural conservation measure.
