The present 1.5 m high weir at Bramming Fish Farm, supplying water for the fish farm production, totally blocks the free migration of most fish species in River Holsted Å – a tributary to River Sneum Å.
With the Houting-project the fish farm will be purchased and the weir dismantled.
The 1.5 m difference in water levels will be equalised by a new meander, which will be constructed on the abandoned production area of the fish farm. The meander will be designed as a 12 m wide stone and gravel riffle with a gradient of 4-5 ‰ and a length of approx. 75 m . The houting - and all other fish species – will thereby gain unhindered access to approx. 11 km watercourse upstream the present fish farm.
Furthermore the closure of the fish farm will result in a significant reduction of pollution loads to Holsted Å and the Wadden sea. This will further contribute to the improvement of the habitat conditions for houting downstream the fish farm.
