I have
my RES/SMB pond over run with bushy pondweed last year. It would have been an ideal environment to have introduced some PK shrimp with all the cover. Wish PK shrimp were more readily available at a reasonable cost.
Put in 4 grass carp last fall to try and get a jump on the pondweed this coming spring so time will tell if the environment changes. But I sure could have used some crayfish or PK shrimp or something to turn some of the weed pressure into protein fish food.
A little bit afraid of the crayfish. I have heard in too high numbers they can go the opposite direction, eat all the plant material, and turn the pond turbid. I do not want to go from one extreme to the other.
All my other ponds have been exceptionally slow to establish ANY kind of natural weed cover (other than spatterdock in my old pond). But for some reason the last two years in this relatively newish pond the bushy pond weed just went nuts.
