Dilution fish farm waste is not an automatic solution

One of the fastest-growing segments of livestock farming in the United States is aquaculture, according to Roz Naylor, a Stanford professor of environmental Earth system science. And like any other form of livestock, fish generate waste. But just what happens to the waste produced by coastal aquaculture has largely been a matter of conjecture.

"For many years, people have assumed that because of the ocean's size, because of the energy in its currents, that any substance you introduced into the ocean would quickly be diluted into concentrations that were barely detectable," said Jeff Koseff, professor of civil and environmental engineering. Now Koseff and Naylor, together with Oliver Fringer, assistant professor of civil and environmental engineering, and a team of colleagues, have developed a computational model that allows researchers to predict where the effluent from a coastal fish farm would go.  Read more ...
