Abundance by yearclass, in numbers of fish
The specific age at which yearclass abundance was calculated is noted in the species headers.
All data updated as of the Nov., 2002 SAFE, unless otherwise noted.
Example- For EBS Pollock it has been estimated that there were 5,017,000,000 age 1 pollock in 1964, which were born in 1963.
