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, ...

Increasingly warm water temperatures brought on by climate change are likely to hit spawning fish and embryos harder than during other times in their life cycle, leaving them more vulnerable to ...

Salmon born in captivity become domesticated in as little as one generation, a new study finds, explaining why hatchery-born fish don't do as well as wild-born ones in Oregon rivers. Researchers ...

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 ...

SOUTH LAKE TAHOE, Calif. – On Nov. 3, 2023, the U.S. Forestry Service temporarily interrupted the water flow to Taylor Creek from the Fallen Leaf Lake dam for three days. This raised concern from ...

The Maryland Department of Natural Resources announced results of this year’s juvenile striped bass survey, which tracks the reproductive success of Maryland’s state fish in the Chesapeake Bay. The ...

Although air and water temperatures are still relatively cool, longer days and increasing air temperatures are slowly warming area lakes. Increasing lake temperatures begin to stimulate natural ...

We all enjoy watching the widlife go about their daily activities. However, scientists say our mild winters and extreme weather is showing a shift in the wildlife patterns. They see this shift in the ...

"Maturation and spawning appear to be induced when the supply of oxygen relative to the weight of individual fish declines. Thus, growing fish gradually become oxygen-limited, and there is a threshold ...

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.
