Abstract

The reproductive behavior in the field and in aquaria was given for fourteen species of darters. The observations were compared with those of previous investigators. The darters were grouped on one basis into those species which spawn in gravel, on plants, on the side of rocks and on the undersurface of rocks. The male is on top of the female when eggs are laid in all the species except those which lay small masses of eggs on the underside of rocks. Here the male is beside the female. The effects of the substrate, size of aquaria and the number of individuals on variations of behavior were briefly discussed. The variation in the expression of territoriality, sex recognition, and other traits was discussed.
