Blue Swimmer Crab location

Region Caught:

  • QLD Blue Swimmer Crab Fishery (514t 2010)
  • NSW Estuary General Fishery (113t 2010)
  • SA Gulf St Vincent and Spencer Gulf (611t 2011-12)

Blue swimmer crabs are caught in a range of fisheries that are managed by different states. In QLD and NSW, there is uncertainty on stock status and some concerns over declining catch rates that require investigation in both states.

In SA, there are concerns around the health of the blue swimmer crab stock in the Gulf St Vincent area. Stock status indicators show that the biomass and numbers of legal sized crabs are at the lowest level since record keeping began and the number of crabs that make up this stock has been declining since 2006. Stocks of blue swimmer crab caught in other areas of SA (Spencer Gulf) are in better condition, but identifying where the crabs are caught can be problematic for consumers.

Blue swimmer crabs are mainly caught using crab pots. These pots are lowered to the seafloor and rest in place until they are lifted up for harvest, with little impact on habitat.

There are minimal catches of threatened species in the blue swimmer crab fisheries and threatened species interactions are low.
