A key item for successful SMB spawning is crayfish in the diet. For the higher percentages of egg hatching proper substrate for nest composition is important. Gravel around the size of golf balls is good. With other substrates the success of egg hatch decreases. Competition for nesting areas with LMB also reduces spawning success.

Given the correct conditions just about any fertile fish will overpopulate and stunt. Population control and management is important if a quality fishery is desired.
