Norwegian aquaculture and fisheries
Side stream biomass of marine origin constitutes an important value-added resource in the Norwegian but also the EU fisheries and aquaculture industry, where most of them are used in a good way. Nevertheless, there is a potential for increasing the utilization rate, especially from the whitefish sector. In Norway, more than 950,000 tons of side stream raw materials was accessible from a base of 3.57 million tons of fish and shellfish in 2018 (Table 1.1.1).
Table 1.1.1 Norwegian fisheries and side stream volumes (2018).
| Whitefish | Pelagic* | Aquaculture | Shellfish | Total | |
|---|---|---|---|---|---|
| Raw material (live weight in x1000 tons) | 756 | 1296 | 1466 | 52.1 | 3570 |
| Available side streams (in x1000 tons) | 329 | 205 | 418 | 10.8 | 953.8 |
| % side stream raw materials of live weight | 42% | 16% | 29% | 21% | 27% |
*Raw material species are herring, mackerel, blue whiting, capelin etc. (those who generate side streams). Source: Richardsen et al (2019)
