Baltic herring and other low-valued fish species are currently underutilized raw materials while fish market in Finland relies in imported fish and cultivated salmon. Consumption of Baltic herring has for example reduced from 3 kg per year / capita in the 80's to 300 g per year in Finland. The reduction has partly occurred due to dioxin content that used to be high. However, the dioxin content has reduced dramatically and Baltic herring has received MSC certificate of sustainable fishing. It would be both nutritious and sustainable raw material.
The Blue Products program aims to valorise the low-value fish species into added-value products and thus assist the Finnish fishing industry to improving its competitiveness. VTT has developed new fish concepts; restructured Baltic herring and 3D printed fish as part of the programme. Restructured Baltic herring is a produced via wet extrusion using milled fish. The production process minimises waste and the products are expected to meet the consumer preferences.

The Blue Products -program is funded by the Centres for Economic Development, Transport and the Environment (ELY Centres) with national funds and funds from The European Maritime and Fisheries Fund (EMFF). The program is coordinated by Österbottens Fiskarförbund r.f. and administrated by Aktion Österbotten r.f.
