Resource

The most abundant organism in the Norwegian Sea

Calanus finmarchicus is a huge biological resource. The annual production in the North Atlantic is many times higher than the total biomass of all fish species in the same area, including cod, herring and mackerel.

The marine zooplankton species Calanus finmarchicus is a free-living copepod (crustacean) with a one-year life-cycle. The species is the key food source for most of the commercially important fish stocks in the North Atlantic. It is generally recognized that only between 10-15 % of the energy is being incorporated as biomass moving upwards from one trophic level to the next in the marine ecosystem. The highest biomass is found at the base of the food pyramid, and utilizing resources such as zooplankton, is thus ecologically efficient and bioeconomically desirable.

Harvesting

The annual biomass-production of Calanus finmarchicus and closely related species in the Norwegian Sea and adjacent oceans is in the range of 200–400 million tons.

Calanus AS has shown that sustainable commercial harvesting of this huge biological resource is feasible, using proprietary technology that the Company has developed. Based on empirical data developed by Calanus AS and scientific advice from Norway’s Institute of Marine Research, the Directorate of Fisheries proposes large scale commercial harvesting with a precautionary approach. The suggested quota of 165,000 tons is regarded by the Company as sufficient going forward, but is still only 10% of what is recommended as a precautionary level set by the Institute of Marine Research. It should also be noted that harvesting of Calanus finmarchicus from an area could result in “compensation growth”, due to better feeding conditions and availability of phytoplankton for the remaining stock of copepods. 


Focus on the environment

In Norwegian waters the harvesting takes place while the copepods are aggregating close to the ocean surface, which is in the period from April to August. As an industrial company focusing on human health, Calanus AS has a tremendous responsibility to develop sustainable practices including harvesting under a strong regulatory regime set by the Government. The Company has relevant and very good in-house competence on marine ecology and resource management, as well as on harvesting practices and quality operations onboard the vessels.

Calanus AS is working together with research institutes and the Authorities in Norway to ensure development of sustainable and precautionary harvesting of Calanus finmarchicus. The Company complies with the applicable Norwegian and international standards of societal responsibility (as outlined in NO ISO 26000), and in the relevant areas of sustainable use of resources and protection of the environment. Furthermore the Company has developed an internal policy for protecting the environment in relation to its business activities (improved resource exploitation and production of raw materials).
