Abstract: | "Intramuscular injection of PGF2 alpha tromethamine salt (Sigma) did not induce sexual behavior in female fathead minnows, Pimephales promelas, when in the presence of male conspecific. However, coresident males exhibited an increased frequency of courtship behavior, consisting of approach and leading, to females following PGF2 alpha treatment. When presented with both saline-injected and PGF2 alpha-injected females, males showed increased courtship only to PGF2 alpha-treated females. Isolated males also showed increased leading behavior following the introduction of water exposed to PGF2 alpha-treated females, but not with water exposed to PGF2 alpha-treated males, untreated females or males, or PGF2 alpha alone. Hence, PGF2 alpha appears to induce the release of a female-specific chemical in P. promelas that triggers courting behavior in conspecific males" |
