Research by Rebecca Asch, a recent graduate of Scripps Institution of Oceanography at UC San Diego, shows a strong correlation between warmer ocean temperatures and changes in the timing of fish ...

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, ...

"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.

A fisheries oceanographer and colleagues introduce a new endocrine-based approach to determine timing of sexual maturation in one of the most important commercial tuna species in the Atlantic. Using a ...

(Beyond Pesticides, June 1, 2010) Atrazine, one of the most commonly used herbicides in the world, has been shown to affect reproduction of fish at concentrations below U.S. Environmental Protection ...

WEST LAFAYETTE, Ind. — Steelhead trout that spawn multiple times have more than twice the lifetime reproductive success of single spawning trout, suggesting there is a substantial benefit associated ...

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 ...

Because they are easier to catch and potentially more threatened by nonlethal effects, fish that form spawning aggregations are at particular risk when those aggregations are heavily fished. To ...

A MONG the apodal fishes of the British Museum described by Kaup in 1856 was a transparent, tape-like fish of about 8 cm. in length, similar to the uppermost specimen in Fig. 1 here reproduced. This ...
