Monitoring Health and Growth of Net Pen Coho

April 12th, 2012 by Joseph Peters Comments Off on Monitoring Health and Growth of Net Pen Coho

Each month Squaxin NR staff takes samples of coho from the net pens to monitor growth progress and fish pathology.   We select pens that are representative of the stocks we have and then seine a random sample of these pens.

The sample is weighed and one hundred of them are measured.   Eight fish are taken from this sample as lethal samples to be looked at by Northwest Indian Fish Commission Fish Pathologists.
