The kisspeptin system is increasingly recognised as a central regulator of reproductive physiology in fish. Unlike mammals, teleosts often harbour two or more kisspeptin genes (e.g. Kiss1 and Kiss2) ...

A Purdue study found that an agricultural herbicide alters reproductive and neuroendocrine genes during embryonic development in fish, a finding that will help establish a genetic profile to determine ...

Pollutants affected fish over multiple generations, according to researchers. Pollution from the production of antidepressant medication is altering fish behavior and reproductive traits, highlighting ...

Chronic exposure to microplastic fibers causes aneurysms, erosion of surface layers and other serious damage to fish gills, and increases egg production in female fish, a sign that chemicals in the ...

The relationships between population density, adult size, and various reproductive parameters (including summed reproductive effort and reproductive success) were examined for the planktivorous coral ...

The level of male and female sex hormones in the largemouth bass that didn’t spawn last year on a state fish farm near Lake Griffin were off kilter and in many cases reversed. But researchers for the ...

To characterize the reproductive success of the extant fish assemblage in the western Grand Canyon portion of the Colorado River, we conducted systematic larval fish surveys in 2014 and 2015. The ...

Pollution from the production of antidepressant medication is altering fish behavior and reproductive traits, highlighting the importance of understanding how such chemicals can affect aquatic ...
