BillD good point. My wild guess estimate assumed the algae was only growing out from shore 6-12ft in an acre pond which is up to 10,000 sqft of algae growth around the pond. This equates to around 1 crayfish per 1-2 sqft of algae growth. This may be a better way to express how many crayfish that are needed to control algae. Expect water clarity to become around 12"-18" with this amount of bottom feeding activity from crayfish. The decreasing water clarity will also reduce light penetration which will slow FA growth on the bottom areas.
