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 ...

"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.

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 ...

Animal biologists and chemists have identified the pheromone involved in the mechanism that triggers puffer fish to spawn on beaches using moonlight. A group of animal biologists and chemists at 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 ...
