Olfactory sensitivity to steroid glucuronates in Mozambique tilapia suggests two distinct and specific receptors for pheromone detection
- BiologyJournal of Experimental Biology
- 2014
The Mozambique tilapia has evolved high olfactory sensitivity and specificity to 3-glucuronidated steroids through two distinct olfFactory receptor types; one detecting a male sex pheromone and a second detecting 17β-estradiol 3- glucuronate, a putative female-derived signal.

Sex Pheromones of C. elegans Males Prime the Female Reproductive System and Ameliorate the Effects of Heat Stress
- BiologyPLoS genetics
- 2015
It is shown that a blend of two ascaroside pheromones produced by C. elegans males primes the female reproductive system in part by improving sperm guidance toward oocytes, revealing an efficient mechanism for increasing coding potential of a limited repertoire of molecular signals.

SYNOPSIS
Although hormonally-derived female sex pheromones have been well described in approximately a dozen species of teleost fish, only a few male sex pheromones have been characterized and the…
Variation in Urinary Amino Acids in the Mozambique Tilapia: A Potential Signal of Dominance or Individuality?
- Biology
- 2016
The urine of male tilapia (Oreochromis mossambicus) contains a pheromone which is—at least in part—composed of two steroid glucuronates. However, the polar fraction of urine (not containing steroids)…
Olfactory sensitivity of the marine flatfish Solea senegalensis to conspecific body fluids
- Biology, Environmental ScienceJournal of Experimental Biology
- 2017
Olfactory sensitivity to conspecific urine and intestinal fluid depends on the sex and maturity of both the donor and receiver in the Senegalese sole, a marine flatfish, which is indicative of pheromonal communication.

Effect of male aggressivity profile on female chemical choice in Nile tilapia
- Psychology, BiologyJournal of Ethology
- 2019
Findings show that females discriminate dominant males that have a high aggressivity profile in favor of males that are less aggressive, which is adaptive for females to choose very aggressive males.

A Sterol-Like Odorant in the Urine of Mozambique Tilapia Males Likely Signals Social Dominance to Females
- BiologyJournal of Chemical Ecology
- 2008
It is suggested that dominant/territorial tilapia males dramatically increase urination frequency in the presence of females ready to spawn and that the urinary odorant acts as a pheromonal signal of dominance, thereby influencing female spawning.
Male urine signals social rank in the Mozambique tilapia (Oreochromis mossambicus)
- BiologyBMC Biology
- 2007
It is suggested that males actively advertise their dominant status through urinary odorants which may act as a 'dominance' pheromone to modulate aggression in rivals, thereby contributing to social stability within the lek.
Brief review of fish pheromones and discussion of their possible uses in the control of non‐indigenous teleost fishes
- Environmental Science

The approach would be to use a variety of pheromones to supplement and increase the efficiencies of other control strategies including the application of poisons or fish with genetic modification, trapping for removal or sterilisation, and barriers to prevent spread.
l-Kynurenine, an amino acid identified as a sex pheromone in the urine of ovulated female masu salmon
- Biology, Environmental ScienceProceedings of the National Academy of Sciences
- 2006
The urine of the reproductively mature female masu salmon (Oncorhynchus masou) contains a male-attracting pheromone, identical to l-kynurenine in spectral and chromatographic properties, which is a reasonable substance for female masU salmon to advertise their readiness for mating.

Electro-olfactogram recordings from female Mozambique tilapia Oreochromis mossambicus gave large responses (up to 45 mV) to water previously occupied by sexually active males, indicating that urine provides the strongest olfactory stimulus for females.

Muscular hypertrophy of urinary bladders in dominant tilapia facilitates the control of aggression through urinary signals
- Biology
- 2012
The results suggest that the larger, more muscular bladder of dominant males is an adaptation, facilitating higher urination frequency, post-renal modulation and storage of larger urine volumes for longer.
