The Abrolhos Islands and Mid West Trawl Managed Fishery (AIMWTMF) is based on the take of saucer scallops (Amusium balloti), with a small component targeting the western king prawn (Penaeus latisulcatus) in the Port Gregory area.
The South West Trawl Managed Fishery (SWTMF) is a multi-sepcies fishery and includes two of the State’s smaller scallop fishing grounds – Fremantle and north of Geographe Bay.
The South Coast Trawl Fishery (SCTF) principally targets scallops (A. balloti) and associated by-products, although in years of low scallop catches licensees may use other trawl gear to target fin-fish species.
Scallop landings for the fishery have varied dramatically over the years, depending primarily on the strength of recruitment.
While the boundaries of the fishery covers a large section of the south coast, the operations of the fleet are effectively restricted to very small areas of higher scallop abundance.
