Will TFS have any effect of FA?
FA (filamentous algae) always starts growing on the bottom then later for several reasons rises to the top - floats. Those masses, "wads" or gatherings of green filaments form wig like masses that you are seeing on the surface and along the shorelines. TFS are not built to collect and eat grouped filaments or strands of FA. For food items, TFS gill rakers strain tiny individual particles out of the water column. See below.
If you want the TFS to benefit from the FA then stock tilapia (TP) who love to eat FA. Then the manure produced by the tilapia fertilizes the water to grow more suspended plankton that the TFS are designed and adapted to eat. Win - Win and Win. You get rid of the FA and then the water is able to grow more plankton to feed the TFS and you can harvest and eat the TP near or at the end of the growing season. IMO pond raised TP are better dinner guests compared to TP bought at the grocery. NOTE: IMO it is always better to stock too many TP than too few because then when TP have eaten all the edible plant materials, TP will and are able to eat and digest organic bottom sediments. This recycles some of the nutrients bound up in bottom organic materials to help grow more plankton both phytoplankton and zooplankton that are relished by TFS.
When I harvest and clean TP near the end of growing season, the TP intestines are full of bottom sediment materials. TP fillets have some added fat content. Why not try to smoking the TP fillets???. They might be as good as smoked salmon.
AI - Threadfin shad are filter feeders that consume plankton, including phytoplankton (microscopic algae/diatoms) and zooplankton (rotifers, small crustaceans), as well as organic detritus.
Gill rakers of TFS are similarly constructed as those of American Shad and gizzard shad.
