Popis:	Successful production of young in smallmouth bass,Micropterus dolomieui, nests varied between 33 and 88 percent over two years. Six variables were measured at each successful smallmouth bass nest. Discriminant analysis indicated that the combined influences of these variables differed between years. Canonical coefficients determined that hours of strong wind followed by degree-days contributed to the observed difference. Nest success was higher when the total hours of wind stronger than Beaufort force 4 was low during offspring development. Higher degree-day values during offspring development were recorded in the more successful year.
