Capture-based aquaculture, ‘fishing method of the future’
--------------------------------------------------------------------------------
A Norwegian scientist at the head of the new Centre of Excellence for Capture-based Aquaculture in Tromsø has trumpeted the capture-based approach as the “future of fishing”.

Senior Scientist Kjell Midling of research group Nofima, who set up the centre at the behest of the Norwegian Ministry of Fisheries and Coastal Affairs, said: “If you catch 100 tonnes of wild cod in April, capture-based aquaculture enables you to sell 200 tonnes in December. This is the fishing method of the future.”

Capture-based aquaculture involves catching fish and transferring them live to sea cages where they are fed and then harvested when there is demand. This practice removes large seasonal variations in supply and, for instance, enables fresh cod to be supplied year-round. Consequently, capture-based aquaculture increases the value of the fish.

Mr Midling said:  “Actually, people have been doing this for thousands of years. Not killing everything man catches has been a rule of thumb in many cultures.”

The focus for the new centre of excellence will be cod, but it will also work with other species including king crab, crayfish and sea urchins.

Mr Midling said:  “There are many tasks to work on and there is a large scope. We need to know more about everything from fish welfare, catching gear, transport and logistics to the markets.”

On a global basis, capture-based aquaculture accounts for more than 20% of the total volume of farmed seafood. However, there are few actors in Norway.

“When we harvest from natural stocks, such as wild cod, there is an upper limit of how much we can catch while still retaining balance in the sea,” said Mr Midling. “If we are to earn more, we need to increase the value of what we have already caught. We need to exploit natural resources in the best way possible to avoid the loss of value along the way.”

Some companies also sell live seafood to their customers. This does not currently apply to cod, but to species such as king crab, sea urchins and crayfish.

Around 20 Norwegian companies currently export live seafood, which accounts for around NOK 45 million per annum (£4.95m).

The Centre of Excellence for Capture-based Aquaculture is responsible for gathering knowledge about capture-based aquaculture in Norway. The centre will advise the relevant authorities about strategies and regulations, and forge strategic links with national and international research institutions, including the Norwegian Institute of Marine Research.

The centre is today responsible for many different projects at Nofima, ranging from topics such as vessels and gear to markets and products.

“Capture-based aquaculture is a concept we will see more and more of in the years ahead,” said Mr Midling. “It stands for enhanced quality of seafood and higher earning power.”
