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

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 …

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 …

Accessory structures to the male reproductive system are known in several families of
teleost, but their role in sperm production patterns and fertilization dynamics is still unclear …

Although the round goby, Neogobius melanostomus, is widespread in the Great Lakes and
has an extended breeding season with a high reproductive rate; its spawning behaviour …

Peculiar fertilization dynamics, with males releasing sperm in mucous trails lasting several
hours, characterize some demersal spawning fish. The mating system was investigated in a …

The spermatozoon of the African catfish Clarias gariepinus is a simple organized
aquasperm although it reveals very unique characteristics: the cytoplasmic channel is …

Fishes have radiated throughout all aquatic environments, and this is reflected in an
extraordinary diversity of mating systems and reproductive behaviors. Many species present …

To test if an increased sperm competition risk affects male behavior and mating decisions of
both sexes, we performed two experiments using the sand goby, Pomatoschistus minutus, a …

Comprising around 30,000 species, fish have developed a large variety not only of
morphology and mode of life but also of reproductive strategies. Many different reproductive …
