Aquaculture wins 2nd place in the 50 Best Inventions of 2009 by TIME magazine

Hydrotech of Sweden has supplied micron screens to the world sensational aquaculture plant that can make Tuna breed in tanks. At 8:47 a.m. on March 12, fish history happened in Port Lincoln, Australia. A tankful of southern bluefin tuna began to spawn.

Clean Seas of Australia has been a true pioneer in aquaculture. Referring to TIME Magazine: "People said,'It can't be done, it can't be done,'" says Hagen Stehr, founder of CleanSeas, the Australian company that operates the breeding facility. "Now we've done it." Scientists believe the breeding population of the highly migratory southern bluefin has probably plummeted more than 90% since the 1950s.

Knowledge and equipment is needed to succeed and Clean Seas has worked with AKVAGroup Denmark to build the aquaculture plant. AKVAGroup Denmark supplied a re-circulated aquaculture system that re-uses the water. Such systems are quite complicated, but have full control of the water quality. Hydrotech delivered the microscreens needed as a key part of the full process of water treatment. Even though Hydrotech has delivered over 4000 microscreens for aquaculture worldwide, this application were quite unique.

"We sure know our microscreens works" says VP, aquaculture, of Hydrotech Henrik Mortensen, whom has worked with re-circulated aquaculturefor more than 20 years "but we were also challenged to make it last long in the warm saltwater".Thus supplying filters in a special Duplex alloy, with a view of long term duty and addressing corrosion problems in a tough environment. All parties in the project knows that long lasting performance is the key to economical success, so no chances were taken.
