Further field studies have been required by the EPA (16). Direct application of copper sulfate to water may cause a significant decrease in populations of aquatic invertebrates, plants and fish (17).   Effects on Aquatic OrganismsHello I just edited this answer Copper sulfate is very toxic to fish.
Jaguarundis are known to live throughout South America, Central America, Mexico and even Texas and southeast Arizona. Jaguarundis live in a variety of habitats, from grasslands to tropical forests, thickets, and even scrubland. Preferring to live near water, they are usually found near lakes, streams, or swamps.
They are good climbers and are comfortable in trees but they prefer to be on the ground, particularly to hunt. A Jaguarundis diet consists of fish, frogs, reptiles, birds, rodents and small mammals. After a gestation period of 70 - 75 days Jaguarundis give birth to a litter of 1 - 4 kittens.
