The devil is in the detail
Researchers have looked at a species of fish to help unravel one of the biggest mysteries in evolutionary biology.
Why marine fish don't go into the deeper blue
Using clay to fight fish disease
A type of clay used in cosmetics, medicine, and papermaking may be just what aquaculture farmers need to fight columnaris—a costly and deadly bacterial disease that affects freshwater finfish worldwide.
Top marine scientists call for action on 'invisible' fisheries
To protect our oceans from irreversible harm, governments, conservationists, and researchers around the world must address the enormous threat posed by unregulated and destructive fisheries, say top marine ...
New species of giant Amazonian fish reported
(Phys.org) —A new species of the giant fish arapaima has been discovered from the central Amazon in Brazil, raising questions about what other species remain to be discovered and highlighting the potential ...
Sequencing of five African fishes reveals diverse molecular mechanisms underlying evolution
In an effort to understand the molecular basis of adaptation in vertebrates, researchers sequenced the genomes and transcriptomes of five species of African cichlid fishes. A research team led by scientists at the Broad Institute ...
Cichlid fish genome helps tell story of adaptive evolution
(Phys.org) —Roughly 40 million years ago, a handful of species of fish from the Nile River went into three lakes in Africa and experienced an unusual flurry of evolution. In one of these lakes as many as ...
Fish species flourish in hypersaline estuary
Scientists have a better understanding of fish capable of living in highly saline estuaries following an in-depth study of the Leschenault Estuary in south-western Australia.
Climate change will threaten fish by drying out Southwest US streams, research predicts
Fish species native to a major Arizona watershed may lose access to important segments of their habitat by 2050 as surface water flow is reduced by the effects of climate warming, new research suggests.
In whole-lake experiment, have invasive crayfish met their match?
Four years ago, UW-Madison researchers wrapped up a multi-year effort to dramatically reduce the population of a destructive invasive species in a northern Wisconsin lake.
Scientists link unusual fish larva to new species of sea bass from Curacao
Identifying larval stages of marine fishes in the open ocean is difficult because the young fishes often bear little or no resemblance to the adults they will become. Confronted with a perplexing fish larva ...
Study shows heart abnormalities in fish embryos exposed to Deepwater Horizon oil
A new study showed that several Gulf of Mexico fish embryos developed serious defects in heart development following exposure to crude oil from the Deepwater Horizon oil spill. The study is the first to analyze ...
The coelacanth leads a monogamous life
Scientists have successfully analyzed the genetic make-up of the offspring of pregnant coelacanth females for the first time. They found that the likelihood that the offspring is fathered by one single individual ...
