Llyn Aquaculture


In the near future, Llyn Aquaculture will embark on a 1,000-metric-ton-a-year recirculating, biofloc shrimp farm in the United Kingdom.  It will use seaweeds and samphire (Salicornia europaea, a salt-tolerant, edible plant that grows in coastal areas) to mop up nitrogen and phosphorous from its wastewater and waste heat from a power plant to keep the water in its tanks warm.  The construction costs for an intensive indoor shrimp farm fall somewhere between $15 and $18 per kilogram of yearly production, which includes an insulated building.  That means a shrimp farm capable of producing 1,000 metric tons a year would cost $15 to $18 million to build.  Mark Rigby, technical director at Llyn Aquaculture, said integrating the farm with seaweed production is a secondary goal and serves to tick the right boxes as far as not releasing nutrients back into the environment.  The company is not relying on seaweed as a major profit stream.  It will be grown outdoors and on a seasonal basis.  Llyn Aquaculture has run a four-year pilot project on its system and does not have a romantic vision of a 100% closed system from day one—although it does not rule out that possibility in the long run.


Founded in 1999 and based on the Llyn Peninsula in North Wales, UK, Llyn Aquaculture operates worldwide, supplying systems and advice in many different countries including, Australia, Singapore, Greece, Italy and Ireland.  Its primarily business is the design, supply and project management of recirculating aquaculture systems (RAS).
