Pond Boss Forums POND CONSTRUCTION Creating habitat Bretski's Fish Cribs- Excuse my Ignorance

I think the primary purpose of Bretski's Fish Cribs since they were placed near the spawn beds for SMB are to be places for the SMB fry to find refuge while they are less than 1" long. IMO the concept is good especially in ponds that do not get a lot of filamentous algae (FA) growth. Dense growths of FA can completely coat the fencing to a point where all the openings are clogged and fish cannot enter or leave the box-like structure. The bottoms of these cribs may remain relatively algae free due shading factor. Bretski may see this post and provide his opinions and experiences so far after having the cribs I place for a few years.
