The Southern Scallop Fishery (SCA 7)

The Southern Scallop (SCA 7) fishery is closed to fishing. It will remain closed until scallop populations recover. Find out what's happening with SCA 7 and how to stay informed.

What is the status of the fishery?

Since 2017, the Southern Scallop (SCA 7) fishery has been closed to scallop fishing. Scallops cannot be taken from:

  • Marlborough Sounds
  • Golden Bay
  • Tasman Bay
  • Port Underwood.

The decision  followed:

  • smaller closures earlier in 2017 and 2016
  • research showing that scallop numbers had dropped.

According to the most recent scallop survey (in May 2020), scallop numbers are still too low to support sustainable fishing.

Strategy for increasing scallop numbers

Since the fishery closure, a strategy has been developed to ensure we are doing all we can to help scallop numbers rebuild to healthy levels. It includes objectives to improve the management of the Marlborough Sounds scallop fishery, and the ecosystem that supports it. It aims to guide the rebuilding of southern scallop numbers to healthy levels as soon as possible. This will provide a sustainable fisheries resource for generations to come.

The strategy was created by the Southern Scallop Working Group (SSWG), and formally approved by the Minister of Fisheries in 2020. The strategy was released after public consultation.

Find out more about the strategy and its implementation

We have a web page where you can find more information on the strategy and its implementation. This includes a related implementation plan recently formed by the SSWG, as well as other related documents and updates.

What about the rest of SCA 7 (Golden Bay and Tasman Bay)?

While the Marlborough Sounds strategy is rolled out, the SSWG will consider how to manage and restore the Golden Bay and Tasman Bay scallop numbers. This will also include Croisilles Harbour.

History of the Southern Scallop Fishery

SCA 7 catch has fluctuated a lot since commercial fishing began in the 1950s. The past 10 years have seen a significant and continuous decline.
