Treatment via feed has increased after 2017. During feed processing, drug residues can be spread to the seabed through feed that is not eaten, in addition to via faeces from the fish, which will also contain drug residues. Medicines will also be able to spread through urine and mucus to the water column. In the "" Risk Report Norwegian Fish Farming 2018 "" by the Institute of Marine Research, it is estimated that feed waste in the form of pellets and feed dust constitutes between 5-11% of the total amount of feed. This means that a large proportion of the growing feed and medicated feed ends up in the sediments below and around the site. A number of organisms in the marine environment can be exposed to the drugs.
Due to environmental risks when using pharmaceuticals and welfare challenges when using non-medicinal methods, there is now a need for new methods for de-lice removal or new methods for administering existing pharmaceuticals. From the industry's perspective, pharmaceuticals added to feed are preferable because this supply route does not require handling of the fish. The disadvantage of oral feeding is that feed that is not eaten by the fish passes through the seine.
In order to avoid unwanted effects on the environment, new ways of allocating the feed drugs can help to reduce negative environmental consequences.
Main objective:
To assess and compare the environmental risk of medicinal products against salmon lice/scorch lice supplied via feed with positive buoyancy and sinking feed.
Sub-goals:
1. To establish a database of existing knowledge about the environmental effects of selected traditional and new feed medicinal products.
2. To model the dispersion of feed drugs added with sinking feed and feed with positive buoyancy using a fine-scale hydrodynamic model and a particle dispersion model.
3. To survey, through field trials, the spread of pharmaceuticals added to sink feed and feed with positive buoyancy in the environment around a plant.
4. To compare modelled and measured concentrations of feed drugs with limit values for effect and assess environmental risk, with particular emphasis on crustaceans and wild fish.
