Learn how the Amazon molly, an all-female fish that reproduces asexually, uses gene conversion to maintain healthy DNA and survive more than 100,000 years without males.

A DNA probing technique clarifies the mechanism behind clonal reproduction of female dojo loach fish, also providing insight into the ancestral origin of the clonal population. A DNA probing technique ...

Even back then, scientists were puzzled. Many prediction models suggested this fish shouldn’t survive beyond roughly 10,000 years. Yet here it is, still going strong far past that window. Wes Warren ...

University of Missouri researchers have shown how an all-female fish species called the Amazon molly defies the long-held belief that asexual reproduction is an evolutionary dead end. The key is gene ...

Percid fish, including species such as Eurasian perch and pikeperch, are increasingly of interest due to their ecological importance and commercial potential in aquaculture. Domestication efforts have ...

Polar fish experience lower mortality than tropical fish, allowing them to delay reproduction until later in life when they are larger and can produce more eggs, according to a study by Mariana ...

A new study examining fishes’ reactions to heat at different stages of their life process has revealed that warming waters could impede reproduction in up to 60% of species. Saltwater and freshwater ...

In 1981, scientists discovered that female fish exposed to high temperatures developed testes instead of ovaries. Since then, over 1,100 studies on different animal species, including 400 on ...
