Researchers discover size gene for salmonhttps://spawn1.ca/index.php/researchers-discover-size-gene-for-salmon/
The size of returning Atlantic salmon is largely dependent on the number of years that the salmon remains at sea before returning to spawn in the river. The genetic basis of this trait has not been previously known, making the management of the impact of fishing difficult. In many Atlantic salmon populations, the sea-age at maturity, i.e. the number of years at sea, has been declining.
