Leaching

Leaching. Leaching is a serious problem more so for soluble components (e.g., starches) in a diet or fecal material than for fibrous (e.g., cellulose) components, and it is recommended that feces be collected as frequently as possible to minimize contact with the water and potential leaching. From: Encyclopedia of Fish Physiology, 2011.
