Multinational food manufacturer sources shrimp reared in closed-loop system

Multinational food manufacturer Findus has committed to meet all of its shrimp supply needs in Sweden from a sustainable start-up company named Vegafish. 


Vegafish uses a ‘biofloc’ method, where microorganisms introduced to a shrimp pond digest shrimp excrement, and are in turn ingested as a protein feed source for the shrimps. This food source removes the need for fishmeal, which is often wasted, leading to deterioration of water quality. Furthermore, biofloc ponds can rear 10 to 40 times more than conventional shrimp farming.

Vegafish’s operations are based in Bjuv, Sweden, where a facility is nearing completion at the end of July. Excess heat from Findus’s local factories is redirected towards this facility in a closed loop system, which also uses robotic monitoring to control heat to optimise growing conditions in the shrimp ponds. The presence of microorganisms makes the biofloc production process self-cleansing and disease-resistant. There is zero water exchange from the plant, and also no flushing of nitrate-laden organic waste into the environment. Locally sourced agricultural by-products and surplus garden peas produced by Findus in Bjuv are used to supplement the shrimp feed. Production is planned to start in autumn and the harvested shrimp product will be organic and antibiotic-free. 

The relationship between Findus and Vegafish is one of the first partnerships between a multinational food manufacturer and biofloc shrimp producer; another example is the Vietnamese Minh Phu Seafood Corp. This project is currently exclusive to Sweden, but there is growing international attention from several buyers in 22 countries, including The Philippines, China, India, and about 10 different countries in Africa. This has provided Vegafish with the incentive to open several more facilities, nationally and internationally. 

Speaking about the future of its shrimp projects, the CEO of Vegafish, Matilda Olstorpe, has remarked “we should have several production plants close to the market, so fresh shrimp can be distributed directly to customers”.
