For years Giant Salvinia has been being sprayed in Texas lakes with chemicals. And when that happens every living organism is affected, including all other vegetation has been affected. Although a big concern is not only the aquatic vegetation, for the habitat of the wildlife, fish and every other living thing beneath that surface. Another extreme concern is about the fish that are consumned by humans. Not only in the lakes that are getting bombarded with chemicals. But even when the gates open on the dam. And that water travels downstream. Many fisherman show a great concern for wildlife and Humanity. And we ask that another method of control be applied other than the toxic chemical warfare tactic.
