Notes from the PI:
How I classified salmon (according to information from Nancy Davis and from looking at her high seas catch (lengths and ages) data [reference pending]):
coho <375mm = juvenile
coho >375mm = maturing
pink <375mm = juvenile
pink >375mm = maturing
The categories for sockeye, chinook, and chum are more difficult to determine and are based on length frequencies as well as age/length data from the high seas cruise Nancy Davis goes on. [reference pending]
sockeye <235mm = juvenile
sockeye >235mm = immature/maturing
The minimum fork length of a sockeye (ocean age 1) was 231mm in Nancy Davis' high seas data (2001) [reference pending]; most were ~300mm
chinook>300mm = immature/maturing
chum<270mm = juvenile
chum>270mm = immature/maturing
The minimum fork length of a chum (ocean age 1) was 280mm in Nancy Davis' high seas data (2001)[reference pending]; most were ~300-350mm
Questions about these data should be directed to:
