      In intensive salmon farming, it is common practice to spread the feed over a large surface area, assuming that spreading of the feed increases feed intake in the fish. However, the impact on the feed pellets during spreading ...
    • Feed intake in Atlantic salmon fed with two different spreading patterns of feed

      Atlantic salmon with initial body weight 0.6 kg kept in 3.3 m3 tanks was fed one meal daily, either by dropping the feed from one point, or by spreading the feed over the water surface, for one month. The relative feed ...
    • Intrinsic settling rate and spatial diffusion properties of extruded fish feed pellets 

      Skøien, Kristoffer Rist; Aas, Turid Synnøve; Alver, Morten; Romarheim, Odd Helge; Alfredsen, Jo Arve (Journal article; Peer reviewed, 2016)
      Spatial and temporal feed distribution in sea cages are important factors for the farmer, fish and environment due to the strong relation to growth, feed loss, pollution and welfare. This study presents a set of experimentally ...
