It is important to develop methods that will produce results acceptable to state agencies, he said.
He said streams should be monitored four times a year and ideally three months apart.

A three foot square of a fine mesh seine was put on the bottom over rocks, and the rocks were systematically moved over the seine and rubbed so the little "critters" that live on them were captured in the seine.
