Question

What is the best method to count microscopic organisms that are 1 mm in size?

Answer 1

You use sampling if they are fairly well spread out. Count just 1/4th the area of your sample and multiply by 4. So if you are looking at a 1" square sample you just count what's in a 1/4" square grid.
