I would try tilapia. Blue tilapia at the correct stocking density have worked really well so far in the ponds where I have used them for this problem. IMO stocking density is the key to success if you go the tilapia route. Keep in mind that unless you change the pond conditions that are favoring the algae mat growth the algae will persist. Favorable conditions: clear water, often presence of blue dye, all other pond bottom plants have been eliminated, no bottom activity, usually black underlying sediments.
