The Group’s primary species are Cape Hake from South Africa and Shark Bay king and tiger prawns from Western Australia. These are premium wild caught species that have become highly sought-after in local and international markets.

The fleet consists of a total of 29 vessels of which 18 operate in South Africa and 11 in Western Australia. The Sea Harvest fleet, operating out of Saldanha Bay on the West coast of South Africa, consists of 4 factory freezer trawlers and 8 fresh fish trawlers. Through an exclusive arrangement with SeaVuna, Sea Harvest also has access to SeaVuna’s fleet of 4 deep-sea trawlers and 2 in-shore trawlers that operate out of Mossel Bay on the Southern Cape coast of South Africa. The Mareterram fleet, operating out of Carnarvon, Western Australia, consists of 11 prawn freezer trawlers.



Cape Hake is caught off the west and south coasts of South Africa, where the unpolluted, nutrient-rich water of the cold Benguela current sweeps up from the Antarctic. Fishing takes place 15 to 120 nautical miles from the shore at depths of up to 800m, using Sea Harvest’s own fleet of single and twin fresh fish trawlers and 4 factory freezer trawlers. Besides Cape Hake, the fleet also catches a variety of by-catch species like monkfish, kingklip and sole.

At sea, Cape Hake are headed and gutted on fresh fish trawlers, and packed on ice for delivery to the company’s shore-based processing facilities. Sea Harvest processes the fresh Cape Hake into fillets, loins, steaks and moulded portions which are quick frozen, locking in taste and texture. A wide range of smoked, coated, crumbed and other value-added seafood products are also produced at the company’s land-based processing facilities.

Sea Harvest’s state of the art factory freezer trawlers catch and immediately process and freeze Cape Hake and assorted by-catch species into a range of frozen-at-sea products. Products include Cape Hake fillets, headed & gutted (H&G) hake, monkfish tails, other by-catch species and premium fishmeal.

As a responsible corporate citizen, Sea Harvest believes in conducting its business in a sustainable manner. Not only does Sea Harvest comply with the regulations and quotas imposed by the South African government and other international organisations, it also plays an active role in creating initiatives for furthering the sustainability of South Africa’s marine resources for the benefit of future generations.


Sea Harvest operates two factories in Saldanha Bay ; a fresh fish factory that processes fresh hake and by-catch species into a variety of chilled and frozen products, and a value-added plant that produces a wide assortment of crumbed, battered and sauced products.

Sea Harvest also has exclusive access to the fresh fish operations of SeaVuna in Mossel Bay. The fresh fish processing plants in Saldanha and Mossel Bay are built on deep-water quays, enabling the trawlers to tie up alongside and speedily off-load into the factories, essentially becoming part of the production lines.

The fresh fish factories produce a wide range of natural products such as fillets, loins, steaks and portions that are either plate frozen, blast frozen or individually quick frozen (IQF) for retail and foodservice markets around the world.

Sea Harvest is headquartered in Cape Town with regional offices in Johannesburg and Durban.



The Mareterram fleet of 11 freezer trawlers operates out of Carnarvon, Shark Bay in Western Australia, and targets western king prawns and brown tiger prawns. The prawns are graded by size, plate frozen at sea and packed into market-ready packaging on board the vessels. In addition to the prawns, Mareterram have an allocated crab and scallop quota which is also packed and frozen at sea.

Fishing takes place within the confines of Shark Bay in water depths of 10 to 40 metres and given the relative low volume nature of the fishery, demands smaller vessels with excellent catching capabilities. Trip lengths for the prawn trawlers are in the region of 22 days, whereafter the fleet returns to port to offload at the start of every full moon closure of the fishery.

The fishery is based on an input control management framework which includes permanent and temporary closed areas, spatial and temporal controls (including moon closures), to manage fishing effort and achieve environmental sustainability objectives.

Product is shipped from the Carnarvon cold store direct to market.

Mareterram is headquartered in Perth with regional offices in Adelaide, Melbourne, Sydney and Brisbane.
