The Icelandic company SR-mjöl hf is based on a state run company, Sildarverksmidjur rikisins, which was established on the opening of the first Icelandic fishmeal factory in 1930.

The present name SR-mjöl is derived from the first letters of the name of the founding company. Today the company is the leading seller of Icelandic fishmeal and fish oil, handling about 55% of the total production in Iceland.
