Fisheries are composed of one or more parts, each of which is entitled to receive an MSC certificate. These parts or “units” are defined by their target stock(s), fishing gear type(s) and if relevant vessel type(s), and the fishing fleets or groups of vessels.

When the term “Unit of Certification” is used for fishing units that are in assessment, it refers to the “Unit of Assessment” or “Unit of potential certification”.

About this Fishery

This fishery, which achieved certification in October 2015, is located in the Gascoyne region of West Australia in the north/northwest waters of Exmouth Gulf.

A fleet of six vessels targets western king prawns (Penaeus latisulcatus) and brown tiger prawns (Penaeus esculentus), using low-opening demersal otter trawls. Nets are sized between 10m and 14m, and each trawl shot lasts from 60 to 200 minutes.

More than half of wild-caught prawns in Australia are now MSC certified. This is important, as in many cases they are found in areas of particular ecological significance, and fishing methods must not damage the delicate environmental balance. Exmouth Gulf itself is home to endangered hawksbill and flatback turtles, whale sharks and migratory seabirds; and includes sensitive habitats such as sea grass and coral. Many other fish and sea creatures are also found there.

“The fishing industry in Western Australia has shown tremendous initiative in championing the sustainability of its fisheries.” - Rupert Howes, CEO, MSC
