A study of the olfactory sensitivity of crucian carp Carassius carassius and goldfish Carassius auratus to 17,20-dihydroxy-4-pregnen-3-one and prostaglandin F2

A study of the olfactory sensitivity of crucian carp Carassius carassius and goldfish Carassius auratus to 17,20-dihydroxy-4-pregnen-3-one and prostaglandin F2

Chemical Senses. August; 184: 427-436

In the male goldfish (Carassius auratus), the hormones 17-alpha,20-beta-dihydroxy-4-pregnen-3-one (17-alpha,20-beta-P) and prostaglandin F-2alpha (PGF-2alpha) have been suggested to act as sexual 'priming' and 'releasing pheromones', respectively. We have in the present study examined the sensitivity of the olfactory receptor cells (electro-olfactogram, EOG) of crucian carp (Carassius carassius) to 17-alpha,20-beta-P, 17-alpha,20-beta-P-glucuronide and PGF-2alpha and compared the responses with the closely related goldfish. The olfactory receptor cells of crucian carp were as sensitive to 17-alpha,20-beta-P and PGF-2alpha as those of the goldfish, indicating that these hormones may function as reproductive signals also in crucian carp. Crucian carp and goldfish detected 17-alpha,20-beta-P down to 10-11 and 10-10 M, respectively. The response was significantly greater at 10-8 M 17-alpha,20-beta-P in both spermiating and immature crucian carp compared with spermiating goldfish. The crucian carp showed a much higher sensitivity to free 17-alpha,20-beta-P compared with its glucuronated form. Immature crucian carp showed a considerably smaller EOG response to 10-7 and 10-8 M PGF-2alpha compared with spermiated and regressed fish. The PGF-2alpha response was significantly smaller in immature crucian carp compared with regressed goldfish.
