Dose fish pee change water quality

Compiling more than 10, lines of data on the waste products of aquatic animals, from lake trout to pond insects to ocean shellfish, was more time-consuming than the ecologist Michael Vanni expected. Why anyone cares about fish pee or frog pee or snail pee in the first place has to do with recycling. Nutrients in an ecosystem are used over and over again as they cycle through the food chain. In a forest, for example, when leaves fall to the ground, fungi and bacteria break them down and return their nutrients to the soil, where plants can use them again. Especially in aquatic environments, Vanni says, animals do a lot of this recycling. When fish excrete nitrogen and phosphorus, algae can take the molecules back up. To answer the question, they gathered as much data as they could find on excretion by animals living in water, whether freshwater or ocean—in other words, anything peeing in the global pool.

The U. The stated purpose of the Clean Water Act is "to protect the biological integrity of the Nation's waters," said Nathaniel "Than" Hitt, a doctoral student in the Department of Fisheries and Wildlife Sciences. That's our task. For many years, regulatory agencies have used chemical standards to assess water quality. Now, researchers are discovering how biological criteria can complement chemical standards to assess the status of water bodies, including streams, rivers, lakes, and estuaries. Stream fish are excellent indicators because different species respond to pollution in different ways. As a result, we can assess the quality of a stream based on the diversity and abundance of fishes we find there," said Hitt, who is working with associate professor of fisheries Paul Angermeier.

Fish Keeping 101: Water Quality & Nitrogen Cycle

Ammonia is formed from the metabolism of protein and is the major waste product of fish. The majority of ammonia from fish is excreted through the gills, with relatively little being lost through urine and feces. Ammonia is also formed as uneaten feed or other organic matter in an aquarium decomposes. High concentrations of ammonia in the water make it difficult for fish to eliminate ammonia from their bodies. This buildup of ammonia can cause stress, gill and internal organ damage, and eventually death.
