Trout Metabolism Characteristics and the Rational Design of Nitrification Facilities for Water Reuse in Hatcheries

Abstract

The literature has been reviewed and quantitative relationships have been derived to express the oxygen required, ammonia, BOD, and suspended solids production as a function of fish length. The temperature dependence of feeding rate and nitrification capacity has been incorporated into a nomograph which predicts the nitrification volume requirements for recycle. Another nomograph was constructed to predict water flow requirements and pollution resulting from trout hatchery operation.
