Scientists from The University of Texas Marine Science Institute and the Scripps Institution of Oceanography have discovered a way to use the incredibly loud, distinctive sounds that fish make when they gather to spawn to protect them from overfishing.

Central Valley rice fields managed as floodplains during the winter can create surrogate wetland habitat for native fish, study shows.

Sex-changing fish exhibit differences in androgen receptor (AR) expression in muscles that are highly sensitive to androgens (male sex hormones) and essential for male courtship behavior, according to a Georgia State University study.

Researchers from the University of Washington and Smithsonian Institution have reported the first observed case of lionfish preying upon a fish species that had not yet been named. Their results, published May 25 in PLOS ONE, may indicate an uncertain future for other fish found in the largely unexplored deep-ocean coral reefs.

Researchers from the Coral Reef Ecology Lab at the Hawai'i Institute of Marine Biology documented the third global bleaching event as it occurred from 2014 to 2016 at the Hanauma Bay Nature Preserve (HBNP) on the island of O'ahu, Hawai'i. Their findings, published in the international journal PeerJ, show that temperature is by far the most influential factor in coral bleaching at this well-managed location where corals, fish, and all other organisms are protected.
