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 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 by the Shedd Aquarium has found that the Chicago River system continues to recover from pollution, as evidenced by the fish species that have been spawning in the river system. A report on ...

"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 ...

Fish spawning aggregations (FSAs) are predictable congregations of conspecific fishes at specific sites and times for reproduction. These events underpin the replenishment of many commercially and ...

Spawning fish and embryos are far more vulnerable to Earth's warming waters than fish in other life stages, according to a new study, which uniquely relates fish physiological tolerance to temperature ...

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 ...

The researchers developed the method specifically for the Gulf corvina, a popular fish in Mexico’s Gulf of California Marine scientists have discovered a way to use the incredibly loud, distinctive ...
