Greetings Fish-Sci folks.
 We are considering a proposal for using herring scale pattern analysis
as a stock separation tool in Alaska.  Several projects were tried here
about 10 years ago and from my reading the results were mixed; with some
success and some failures.  The measurements collected in those studies
were distances between the scale annuli along a single axis.
 My questions are
1) Is anyone currently using scale patterns on a routine basis to
identify herring in mixed stock fisheries.
2) If so, what  measurements are being used, how are those measurements
collected, and have other patterns in the scales been evaluated.

Herring scales are a new subject for me, so any other advice or
suggestions would be appreciated.
(I've done some literature review and the most recent paper on my
list was  Barros and Holst 1995)

Please respond to my email address and if there is sufficient interest
I'll post a summary to the list.

Thank you
