in agricultural land and in forests are other areas of research. The chemical and biological quality of
water is regularly monitored in many lakes in Sweden.

10 Themes – Local raw materials for aquaculture feed
In the following a list of potential local resources for use in fish feed are listed:
10.1 Plant substitutes for fish meal and fish oil
Due to environmental aspects the high amount of fish meal and fish oil used for aquaculture feed
has been of concern. Many projects have been run in recent years testing different substitutes for
high quality fish products. The research institute Matis in Iceland has tested the possibilities of
replacing fish meal and fish oil with different raw materials of plant origin for Arctic charr feed.
The results showed that Arctic charr seems to have limited ability to utilize soybean meal and it is
suggested to include maximum 15% in the diet, similar to the limits that are common for Atlantic
salmon diets. The limits for use of corn gluten meal in starter diets seem to be ≤ 18% but this raw
material was not tested in bigger fish. The response of Arctic charr to the use of rapeseed meal as
protein source was positive and even as high inclusion as 30% in the diet did not have negative
