Abstract: The white amur fish has potential for biological control of vegetation in waterways, lakes, and reservoirs. However, intensive and widespread use of white amur should be avoided until it is certain that the fish will not become a naturalized pest. The purpose of the research reported herein was to determine the feasibility of producing populations of white amur which could not reproduce. Gynogenesis, androgenesis, and sex reversal procedures were studied as methods for making populations of one sex. Analysis of morphological and biochemical traits showed that monosex white amur could be produced and that these fish are identical to female fish produced by usual fertilization methods. A model for the costs of an operational hatchery facility and weed control program suggested that treatment cost with monosex amur would be $150 per acre in 1975-77, but only about $2 per acre after 1977.
