Abstract

The invention relates to a fish-farming device comprising a number of bags lowered into the water. The upper part of the bags is configured with non-water- permeable walls, whilst the lower part allows water to pass through. Fresh water is fed continuously into the upper part and dirtied water is led away from the lower part and up along the outside of the bag.

464 217 ä, PATENTKRAV Anordning för odling av fisk i kassar nedsänkta i vatten där friskt vatten kontinuerligt tillförs, varvid kassen eller kas- sarna innefattar en övre del med icke vattengenomsläpplig vägg och en nedre del med vattengenomsläpplig vägg och botten och varvid friskt vatten kontinuerlilgt tillförs den övre delen, medan nedsmutsat vatten förs bort från den undre sá att en relativt långsam, nedàtriktad strömning skapas i kassen, k ä n - n e t e c k n a d därav, att nedsmutsat vatten strömmar ut genom kassens företrädesvis konformade botten (6) och transpor- teras upp till ytan vid sidan av kassen eller mellan kassarna (9), varvid vattnet passerar genom en smal zon (ll) belägen i närheten av övergången mellan kassens övre och nedre del i vilken zon en högre strömningshastighet föreligger varigenom ett lägre tryck erhålls. Anordning enligt krav 1, k ä n n e t e c k n a d därav, att friskt vatten tillförs vid väggen i den övre delen av kassen, företrädesvis genom ett antal pá olika nivåer belägna hål så riktade att en roterande strömning skapas i kassen. ~1 ß:464 217 ä, PATENT REQUIREMENTS Device for growing fish in bags immersed in water where fresh water is continuously supplied, the box or bags comprising an upper part with a water-impermeable wall and a lower part with a water-permeable wall and bottom and wherein fresh water is continuously supplied the upper part, while contaminated water is removed from the lower part so that a relatively slow, downward flow is created in the box, characterized by the fact that contaminated water flows out through the preferably cone-shaped bottom (6) of the box and is transported up to the surface next to the box or between the bags (9), the water passing through a narrow zone (II) located in the vicinity of the transition between the upper and lower part of the box in which zone a higher flow rate is present whereby a lower pressure is obtained. Device according to claim 1, characterized in that fresh water is supplied to the wall in the upper part of the box, preferably through a number of holes located at different levels so directed that a rotating flow is created in the box. ~ 1 ß:
