A word of caution -according to Wikipedia, Hydrilla is a hyperaccumulator of Mercury, Cadmium, Chromium and Lead. This means its very important to use only plants grown in very pure waters, and even then, to monitor them closely for these metallic contaminants -whether the plant (or its products) are used as feed for humans or animals, or even as fertilizer. Grass carp, an herbivorous fish with a ferocious appetite has been proven effective to help control hydrilla. If Wikipedia said the sun rose today I would check to make sure. The plant is also known for its extremely high concentration of calcium, vitamin B-12, iron and magnesium. Unfortunately, the fish does not eat only hydrilla and also will consume most submersed and emersed aquatic plants once hydrilla is depleted. It has several adaptations that allow it to be so successful: It can tolerate lower light conditions than most aquatic plant species, which allows it to begin photosynthesizing earlier in the morning, giving it an advantage.

Pennsylvania Flora Project. Les, D.H., L.J. IFAS. University of Alaska - Anchorage. Hydrilla (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, Hydrilla verticillata, though some botanists divide it into several species.It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory, Queensland, and New South Wales. Invasive Aquatic Species Program, Maine Department of Environmental Protection. 2002), Photo by Raghavan Charudattan; University of Florida. C.C. Here is information about the aquatic plant Hydrilla. Herrera Environmental Consultants. National Genetic Resources Program. It has 16 percent more available dry matter for fodder than cattails and no bad chemicals were found in it during the examination for cattle food. Both biotypes depend on tubers for overwintering, although monoecious hydrilla exhibits a more annual habit than the dioecious type, with abundant tuber/turion production around September (Owens et al. Maine DEP 2015 Invasive Aquatic Plant Map. 2013. Northeast Aquatic Nuisance Species Panel. Hoyer, M.V., M.W. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory, Queensland, and New South Wales.[1][2][3].

It has several adaptations that allow it to be so successful: It can tolerate lower light conditions than most aquatic plant species, which allows it to begin photosynthesizing earlier in the morning, giving it an advantage. The first definition of hydra refers to the many-headed beast in Greek mythology. Recent research into molecular techniques for identifying hydrilla and its biotypes has proven successful (Verkleij 1983; Ryan et al. Falk, J. and T. Bryant. Products To Physically Manage Hydrilla- WeedShear. Chester, NJ. We see Hydrilla as a locally available FREE compost with NPK fairly comparable to conventional cover crops typically grown in Florida. Bowen. Hydrilla can grow in almost any freshwater: springs, lakes, marshes, ditches, rivers, tidal zones. It mainly spreads vegetatively through dispersal of plant fragments, axillary turions, and tubers (Langeland and Sutton 1980). Fertile seed production was reported in the monoecious type (Langeland and Smith 1984). It was subsequently found in a Miami canal, and from there it spread. 2015. iNaturalist research-grade observations. and J.M. Van, V. Carter, and A.H. Pieterse. Madsen, J.D., G. Ervin, V.
