Previous attempts to artifically spawn the grass carp have been unsatisfactory, with complete failure or insignificant success using the Russian method des~ribed by A. G. Konradt (1965). The same basic procedure, with variations in hormone, size of dose, and number of injections, proved to be successful in our attempt to spawn four year old fish. The following significant observations were made: I. Human chorionic gonadotropin, used as stimulating injections, and dry, whole carp pituitary, used as the resolving injection, produced a high percent of viable eggs. II. Extending the period of development within the female from 36 hours to 60 hours proved to be more effective in producing mature eggs. III. The Spawning season is approximately one month in Arkansas. IV. Mechanical factors and physical conditions such as water temperature, density of eggs in jars, suspended clay particles, and rate of water exchange (rolling rate) effect the success of hatching in jars. V. Paddle wheels used to roll the eggs proved to be highly successful for hatching grass carp eggs. VI. Grass carp fry show rapid growth and feed well on plankton and commercial minnow meal. Two hundred and seventy thousand (270,000) fry were produced during these experiments.
