I like the idea of getting some crawfish and am looking into sources for them in SE Michigan. I have some questions:
What is the down side of native crawfish - nonburrowing kinds?
What if you want to get rid of them at some point and don't have fish? How do you eliminate them? (I am a bit worried about introducing something that is not already there).
Off the topic of crawfish but still algae control - what is the effectiveness of mechanical removal of FA? I made an algae rake and have pulled most of the mats off the pond tonight. I am wondering if this is worth the labor?
Am I better off trying some of the algaecides before going to crawfish?
Appreciate all your inputs and suggestions.
