However, published length-weight relationships are sometimes difficult to use, as they may be based on a length measurement type (e.g., fork length) different from one�s length measurements (expressed e.g., as total length). 1986. 23, 321 p.

Actually, that’s not entirely true – nowadays, American trout anglers, who are some of the most radical conservationists in the angling world, have turned largely to length as a way of recording their catch-and-return successes.
