“…For example, in fish, water-born steroids, prostaglandins and their metabolites have been found to alter behavior in goldfish (Carassius auratus) (Dulka et al, 1987;Poling et al, 2001), African catfish (Clarias gariepinus) (Resink et al, 1989), and Atlantic salmon (Salmo salar) (Moore and Scott, 1991). However, few studies on the pheromonal effects of hormones have been done for invertebrates.…”

SynopsisWe examined the behavioural and biological functions of prostaglandins (PG) of F-type as a chemosensory signal during spawning in Arctic charr . Immunoassay revealed F-type PGs in water inhabited by ripe charr of both sexes performing spawning-related acts . High concentrations of immunoreactive PGFs seemed to coincide with male spawning activity. Ripe isolated males were more odorous to other charr (as assayed by EOG) than either females or immature charr . When these males received chemical cues from ovulated females, they increased their release of odorants, including F-type PGs, into the water . PGF 2a at concentrations of 0 .1 nM attracted ovulated females and ripe males . It also stimulated digging behaviour in mature females . It is concluded that F-type PGs or their derivatives are released by ripe males on the spawning grounds to attract females and elicit their spawning behaviour .

“…Taken together, our results and the above findings suggest that fish V2Rs may also detect specific amino acids as sex pheromones. The hydrophilic property of the amino acid pheromone may be advantageous for the masu salmon, because reproductively mature females need to advertise their mating readiness and location more widely to both anadromous and river resident males in mountain streams, which is in contrast to many other species that possess relatively hydrophobic pheromones, namely, steroids and prostaglandins (2)(3)(4)(5)(6)(7).…”

“…Many fish species release steroids or prostaglandins as sex pheromones (2)(3)(4)(5)(6)(7)(8)(9), as demonstrated in the goldfish (Carassius auratus) (4,5). These pheromones are broadly termed ''hormonal pheromones'' because they or their precursors act as hormones in fishes (10).…”

Many animals employ sex pheromones to find mating partners during their reproductive seasons. However, most sex pheromones of vertebrates remain to be identified. Over the past 20 years, steroids and prostaglandins have been identified as sex pheromones in several fishes. These pheromones are broadly termed “hormonal pheromones” because they or their precursors act as hormones in these fishes. Hitherto, no other type of sex pheromone has been unambiguously identified in teleost fish. Here we report the identification of a “nonhormonal pheromone” in teleost fish. The urine of the reproductively mature female masu salmon ( Oncorhynchus masou ) contains a male-attracting pheromone. Bioassay-guided fractionation yielded an active compound that was identical to l -kynurenine in spectral and chromatographic properties. l -Kynurenine is a major metabolite of l -tryptophan in vertebrates. This pheromone elicits a male-specific behavior at even picomolar concentrations; its electrophysiological threshold is 10 −14 M. l -Kynurenine is a reasonable substance for female masu salmon to advertise their readiness for mating.
