It matters who your mother is, even for fish
OPINION: New research could result in both bigger and better farmed fish.
The amount of fish in the world is being reassessed upwards. Some ten billion tonnes of fish that live at depths down to a kilometre are not fished at all. A University of Bergen professor thinks this biomass will be much more important for humankind in the future.
Cod migrate from the Barents Sea to the Lofoten Islands in North Norway to spawn every winter. The fishing season for these large spawning cod, called skrei in Norwegian, is currently open. A traditional North Norwegian serving of the fish is a super source of vitamin D.
Zebrafish have been used as a research standard to help scientists expand our understanding of everything from skin cancers to cardiovascular disease. But one Norwegian researcher cautions that research that relies on zebrafish might be less reliable because the fish are not fed a standardised diet.
