RNA expression in a cartilaginous fish cell line reveals ancient 3′ noncoding regions highly conserved in vertebrates
The authors established a cartilaginous fish cell line [Squalus acanthias embryo cell line (SAE)] derived from the embryo of an elasmobranch, the spiny dogfish shark S. acanthias.

Epizootics of wild fish induced by farm fish
The continuing decline of ocean fisheries and rise of global fish consumption has driven aquaculture growth by 10% annually over the last decade.

Structural and functional diversification in the teleost S100 family of calcium-binding proteins
The origin of the S100 family predates at least the segregation of jawed from jawless fish and some extant family members predate the divergence of bony from cartilaginous fish.

Physical characteristics of Sharks
Sharks (superorder Selachimorpha) are a type of fish with a full cartilaginous skeleton and a streamlined body.

A practical approach to phylogenomics: the phylogeny of ray-finned fish (Actinopterygii) as a case study
A genome-comparison strategy to identifying nuclear gene markers for phylogenetic inference and apply it to the ray-finned fishes – the largest vertebrate clade in need of phylogenetic resolution

Duplication of the dystroglycan gene in most branches of teleost fish
The authors unravelled new important molecular genetic details about fish orthologous DGs, which might help to increase the current knowledge on DG expression, maturation and targeting and on its physiopathological role in higher organisms

Salmon go veggie to save wild fish stocks
Salmon, like humans, require omega-3 fatty acids in their diet to function healthily.

The Pied Piper of Fish
Fishy noises could be the answer for improved reef fisheries management according to an international team of researchers.

Do smelly fish make better friends?
Researchers at Glasgow University and the FRS Freshwater Laboratory at Pitlochry have shown that Scottish salmon are much more likely to fight each other when their smells are concentrated

Love calls from the bottom
Some men send flowers, others send chocolates. But one species of fish has a rather unusual method of seducing the opposite sex.

Restoring fish populations leads to tough choice for Great Lakes Gulls
Seabirds must switch to less nutritious terrestrial prey or go hungry

Can we identify escaped salmon by means of their DNA?
Escaped salmon are a problem for the fish-farming industry.

Coralreef fish desperately need mangrove forests and seagrass fields
Biologists from the University of Nijmegen have demonstrated that some coral fish really do choose nursery grounds before heading for the coral reef.

Convergent evolution of molecules in electric fish
Having a set of extra genes gave fish on separate continents the ability to evolve electric organs, report researchers from The University of Texas at Austin.

Store-bought freshwater fish contain elevated levels of mercury, arsenic and selenium
White bass wild-caught and sold commercially contained significantly higher levels of mercury, arsenic and selenium than fish caught near former industrial areas.

Study uses stream fish as indicators of water quality
The U.S. Environmental Protection Agency has approved a new partnership with Virginia Tech's College of Natural Resources to improve the way the Clean Water Act is implemented in Virginia.

Puberty blues: goby fish choose their sex to find a mate

Revolutionary technology bringing fish to the desert
The world-first project will help to provide people living in barren regions with a vital source of protein and a valuable, if unlikely, cash crop.

Elephantnose fish 'see' with their chin
In complete darkness the animals can even distinguish dead organisms from living ones at a distance

Tracking fish by sonar to prevent over-fishing
Marine researchers and scientists have long sought a practical way to track the position and migration of fish in the world's oceans in order to provide research data for stock management and fish conservation
