Contrary to what is stated in biology textbooks, the growth of fish doesn’t slow down when and because they start spawning. In fact, their growth accelerates after they reproduce, according to a new ...

A consistent metabolic ratio found across 133 Chinese marine and freshwater fish species provides new evidence in support of the idea that fish become sexually active – and spawn for the first time – ...

A new study provides the first detailed documentation of a shallow-water fish diving 450 feet deep to spawn. Uncovering this very rare spawning behavior in bonefish (Albula vulpes) is unprecedented.

Owing to a lack of basic information on the biology of zebrafish (Danio rerio), lab managers must often base decisions regarding the care and use of this species on anecdotal information. In an effort ...

Artificial reproduction in fish species encompasses a suite of techniques designed to overcome the limitations of natural spawning. By harnessing hormonal stimulation, controlled environmental ...

Climate change may be depriving juvenile fish of their most crucial early food source by throwing off the synchronization of when microscopic plants known as phytoplankton bloom and when fish hatch, ...

A new peer-reviewed research paper, authored by Shedd Aquarium and published in Journal of Great Lakes Research, assesses the fish species that spawn in the Chicago River to sustain and support ...

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 ...

The spawning event at the Moore Reef on Sunday night was witnessed by marine biologists, videographers, and PhD students from UTS Sydney and was part of a reef-wide synchronised reproduction cycle ...

In a breakthrough moment for reef recovery spawning of new coral planted by hand off the coast of Cairns has been documented on video for the first time in Australia. The spawning event at the Moore ...
