Abstract

Abstract Fathead minnows (Pimephales promelas) of normal and rosy red color varieties were cultured under similar conditions in shallow (average depth, 0.6 m) and deep (1.1 m) 0.1-ha ponds from August to October 1992. Rosy red fathead minnows had slower growth rates and lower coefficients of condition (weight : length3) than normal-colored fathead minnows. Survival and total pond production did not differ between the color varieties in shallow or deep ponds. Mild weather conditions may have obscured the potential effects of pond depth on production and growth.
