Abstract
Evidence is presented that a simple power equation of the formX t −X m =±b(|tࢤt m|)B can describe growth in length and weight of fishes, whereX t denotes fish length or weight at aget, X m is length or weight (L m orW m ) at a reference aget m , andb andB are parameters to be estimated by the least squares. The optimum age of fish populations (t y ) may be estimated by the equationMW m /b=±y B(B/y-M) whereM denotes natural mortality and wherey=t y -t m .
