TEACHING IN THE LABORATORY

A simple and inexpensive apparatus for measuring fish metabolism

Département de Biologie, de Chimie et des Sciences de la Santé, Université du Québec à Rimouski, Rimouski, Quebec G5L 3A1, Canada

Abstract

A simple, noninvasive, and economical home-made respirometer has been used to determine the standard metabolism of goldfish. The apparatus has been tested on several fishes and has proved its accuracy in determining a mass effect on standard metabolism. The apparatus can be made easily by middle school, high school, and undergraduate students and can be used to introduce them to basic concepts in animal physiology and in biological statistics.

Key words: goldfish; standard metabolism; oxygen consumption; respirometer
