Interspecific Effects of Sex Pheromones in Fish
Goldfish and other teleosts use released hormones (steroids, prostaglandins) as sex pheromones (Sorensen and Stacey, 1990; Sorenson, Irvine, Scott and Stacey, 1992; Stacey and Sorenson, 1991) raising the question of whether such pheromones can be species-specific, given the limited chemical diversity of hormones. This complex issue involves consideration of the specific nature of reproductive sympatry, of non-hormonal components of the pheromone which could create species specificity, and of non-olfactory cues which might obviate the need for a species-specific odor. This paper presents experiments which address the problem of species-specific sex pheromones in fish by examining responses to heterospecific odors prepared from gonadal fluids and urine of several teleost species.
