The fish farming industry has been more focused on the quality of eggs or larvae rather than
that of sperm, even though the quality of both gametes may affect fertilisation success and …

Females frequently mate with several males, whose sperm then compete to fertilize
available ova. Sperm competition represents a potent selective force that is expected to …

Reproductive Biology of Teleost Fishes is the first integrated review of the reproductive
biology of the bony fishes, which are the most species-rich and diversified group of …

Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics
(ARTs). Usually, males attempting to monopolize access to females or fertilizations are …

Successful fertilization in marine organisms that release sperm into seawater is potentially
limited by the rapid dilution of gametes; cases of severe sperm limitation have been …

Among vertebrate classes, fishes exhibit by far the greatest variability in competitive and
cooperative behaviors in male reproduction. Scramble competition between reproductive …

Sperm competition is a powerful selective force that has shaped sexual traits throughout
animal evolution. Yet, how fertilization mode (ie external versus internal fertilization) …

Understanding why there is extensive variation in sperm form and function across taxa has
been a challenge because sperm are specialized cells operating at a microscopic level in a …

The Gobiiformes is one of the most diverse orders of the Percomorphs, with approximately
2000 species in 270 genera. They represent 5 to 10% of all teleosts, with species occurring …

In this study we compared the insemination efficiency of two alternative mating tactics
(courtship and sneak mating) in the guppy Poecilia reticulata by quantifying the number of …
