We describe the procedures used for the intensive spawning, egg incubation, and production of smallmouth bass Micropterus dolomieu fry. These techniques have evolved over a 5‐year period and culminated in a mean annual production rate of 1,812 fry/kg female, a rate that compares favorably with the 1,093 fry/kg female rate obtained using previous methods. This intensive method allows high broodfish stocking rates (e.g., 247 pairs/ha) and requires small pond space. The drawbacks of the method are identified and ways to improve them are discussed.
