here in citrus cty fl, our famous spring fed Crystal River used to be famous for it's clarity, now it is suffering from poor spring flow (over use of aquifer, and drought) high nitrogen( from runoff of fertilizer) elimination of native tapegrass,( saltwater intrusion from no name storm in 80s which killed most of it off, and forage by increasing manatee population) and an infestation of lynbya, and other filamentous algae which form large mats, on bottom killing off grasses. Many techniques are being used to save the river, could stocking of native flagfish and other algae loving natives, be another effective tool?? opinions please.

i guess the most important question is can they survive and devour toxic cyanobacteria like lyngbya?

Don,

In my professional opinion, re-introduction of native fish species to help bring the system back into balance is a valiant idea. Perhaps if the fish can get the algae under control, re-introduction of native aquatic plant species could take place? It's sure worth a shot!

I don't know of any fish that eats those mat-forming blue-green algae (Lyngbya, Oscillatoria, Phormidium, etc). Unless nutrient runoff from the land is managed better, I doubt there's any in-the-water remedies that will work.
