BISMARCK — North Dakota Game and Fish fisheries biologists spend a lot of time in fall surveying district lakes and the Missouri River System in North Dakota looking for natural fish reproduction, ...

Parental egg-care in fish traps them in an evolutionary dead-end through the loss of the chorion-hardening system, according to scientists from the Institute of Science Tokyo. Fish have diverse ...

Not all fish play by the same reproductive rules. Evolutionary biology reveals how deception became a successful mating ...

Even accounting for their proportionate size, bigger female fish produce many more offspring than smaller fish, a new study reveals. The results hold implications for fisheries managers, since climate ...

A research team led by David Reznick, a professor of biology at UC Riverside, has found that as some populations of an organism evolve a longer lifespan, they do so by increasing only that segment of ...

Researchers from Institute of Science Tokyo present the underlying reasons behind the evolutionary bias in reproductive strategies of egg-care species. Using 240 whole genome sequences of fish species ...
