Adding 40 tilapia to 0.1 ac should pretty quickly notably reduce a pretty heavy FA problem. That equates to 400/ac. If there were 5 fish (4"-6")/lb is 80lb/ac; 3.5 fish/lb(6"-8") that is 114lb per ac and 2 fish of 6"-9" per lb is 200lb/ac. Generally 30-40 lb per ac is used. Please try to get a current pic of the pond's FA and keep track of the algae reduction rate and then post another picture for reference and a reader education.
The crayfish could easily be a northern crayfish as noted by quarter acre. Thanks
