Definitions

  • the present invention relates to a technical solution for the removal of parasites from fish, or specifically an assembly for removing sea lice from fish in a body of water.
  • a challenge in the fish farming industry is to continuously maintain the health and wellbeing of ones bred fish stock, so that the bred fish upholds a preferred meat quality and visual appearances for buyers and consumers.
  • a potential disruptor of the health and wellbeing of bred fish is the occurrence of marine parasites, such as sea lice.
  • Sea lice are small parasitic crustaceans which attaches itself on to a fish, e.g. salmon or trout. Sea lice feeds on the slime, skin and blood of a fish, creating lesions which makes the fish susceptible for viruses, bacterial infections and fungi. Said lesions, in the form of open wounds, also affects the saline balance of the fish, wherein open wounds due to sea lice attacks makes the fish further susceptible for attaining lethal levels of salt from the surrounding sea water, increasing its stress levels and lack of appetite. Furthermore, should the fish survive a sea lice infection or several, the saline imbalance may negatively impact the growth rate of the fish.
  • WO2015043603 A1 and WO 9824304 describes a delousing process wherein the fish is in the same water at all times during processing.
