Squeeze them for gametes. Will work this time of year.
Hi Jim,
Just a few of questions about GSF specifically.
Could you describe how to do the squeeze most effectively and with least harm to the fish? I'm imagining applying pressure from the front of the abdomen to the rear like milking.
Do eggs come out freely from GSF? I remember attempting this with BG many years ago and found it to be difficult.
Do you seek a positive identification for both sexes? Or can a negative indication of one sex be highly predictive of the sex of the specimen.
Is there a best temperature to test sex by this method?
