While scientists have developed methods to predict aspects of fish diversity in specific river locations, a model to understand what factors may drive a comprehensive suite of fish biodiversity patterns in a large and complex system of rivers has been elusive.

Results are in from last year’s fifth annual Bonefish Population Census in the Florida Keys and the bonefish population has remained fairly steady from 2006, however, the number of volunteers participating in the annual event continues to grow.

Sturgeon fishers did not fear to experience Sunday chilly weather and cold to catch 297 sturgeons. The number of harvested fish was not enough for the State Department for Natural Resources to end the 2008 season.

Where have all the bridle shiner gone? That’s the mystery The Academy of Natural Sciences’ fish scientists are trying to answer, and the outcome will shed light on the environmental health of the Upper Delaware River.

Using recently discovered “fossil snapshots” found in rocks more than 500 million years old, three University of Kansas researchers have described the oldest definitive jellyfish ever found.

When David Jones, a fisheries oceanographer at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) located at the University of Miami’s Rosenstiel School, set out to design a better light trap to collect young reef fishes, he never imagined his invention would contribute to the discovery of a new species.

Sleep disorders are common and poorly understood. In humans, narcolepsy is a sleep disorder associated with sleepiness, abnormal dreaming, paralysis and insomnia. Neuropeptides called hypocretins are implicated in this disorder.

Scientists at the Stanford University School of Medicine have hooked a fish that suffers from insomnia in their quest to understand the genetics behind sleep disorders.

Embryologists at UCL (University College London) have helped solve an evolutionary riddle that has been puzzling scientists for over a century. They have identified a key mechanism in the initial stages of an embryo’s development that helps differentiate more highly evolved species, including humans, from less evolved species, such as fish.

From 135,000 to 90,000 years ago tropical Africa had megadroughts more extreme and widespread than any previously known for that region, according to new research.

While sharks instill fear in beachgoers worldwide, they instill a deep sense of curiosity in UT assistant professor and shark expert Dan Huber.

An international team of scientists from Canada (Universitй Laval), the U.K. (University of Hull, Cardiff University) and Spain (Doтana Biological Station), have discovered that a pair of closely related species of East African cichlid fishes – a group of fish whose diversity comprising hundreds of species has puzzled evolutionary biologists for decades – evolved divergent immune gene adaptations which might explain why they do not interbreed, despite living side by side.
