Crayfish can cause turbidity issues in fisheries which lack dense enough populations of apex predator fish to manage their populations. Are you experiencing turbidity issues?...
My summer secchi readings where 11-13" all summer UNTIL I recently removed 150 crawdads: 4-5" long. Within a week the muddy looking waters cleared to 22-23" and has stayed there...so, I would say that the craws are mostly to blame. I plan to enter next season with a close eye on clarity and remove some more craws. I have done some throw netting and have only caught larger craws. I suspect my original stocked craws have grown out in front of my game-fish and need to be eaten down. Next year's clarity should be improved one way or another (trapped and/or foraged).
...let me know I will help in any manner possible.
I am open to any and all suggestions...thank you!
