The closed concrete fleet retrieves water from 20 meters depth, has filters on the intake water and self-produced oxygen is added as needed. Thus, the smolt will have almost ideal conditions for growth. The goal is to take the fish up to half a kilo in three months.
A new closed fish farm in the form of a concrete fleet is being transported from Stamneset in Bergen to the Ådnekvamme site in Masfjorden, north of Hordaland. In addition to modern equipment for water treatment, it has a 1000 cubic meter large pool for ingrowing of smolt. Here, the fish will meet ideal conditions for rapid growth without parasites and with stable water quality.
The goal of the company Engesund Fiskoppdrett is to take the fish from the smolt stage up to half a kilo in three months. Making use of large “postmolt” is an increasing practice and is something the company has experience with earlier. Already in 2012, they grew 70,000 fish of 400 grams.
Gisle Andre Enstad has been Engesund’s project manager and takes position as production manager when the fleet will be in operation.
“It went great and we could start slaughtering already after 11 months. That is why this concrete pen is something we have dreamed for a long time, “Gilje told Kyst.no.
The fish from the new fleet will be scheduled every two years respectively in the locations of Duesund or Laberget. The fleet holds 1000 kbm, so with a density at the end of each production of around 50 kg / kbm, it indicates about 100 000 fish per cycle.
“We are excited about this. Experiences from others who have tried postmolt is that this is not always straightforward. This is a pioneering work. But we have good faith in our concept, he emphasizes.
