Far-ranging fin whales find year-round residence in Gulf of California

Thu, 10 Jan 2019 16:09:38 EST ~ Researchers from Mexico and the United States have concluded that a population of fin whales in the rich Gulf of California ecosystem may live there year-round -- an unusual circumstance for a whale species known to migrate across ocean basins. Find out more...

Fish farmers of the Caribbean

Thu, 10 Jan 2019 14:17:12 EST ~ There are only so many fish in the sea. And our appetite for seafood has already stressed many wild fisheries to the breaking point. Meanwhile, the planet's growing population will only further increase the need for animal protein, one of the most resource-intensive types of food to produce. Find out more...

Murky water keeps fish on edge

Thu, 10 Jan 2019 09:10:16 EST ~ Fish become anxious and more cautious when water quality is degraded by sediment, an effect that could stunt their growth and damage their health. Find out more...

Wed, 09 Jan 2019 14:26:26 EST ~ The stomach contents of ancient whale Basilosaurus isis suggest it was an apex predator, according to a new study. Find out more...

Technique boosts omega 3 fatty acid levels in brain 100 fold

Tue, 08 Jan 2019 12:54:17 EST ~ Researchers report that adding a lysophospholipid form of EPA (LPC-EPA) to the diet can increase levels of EPA in the brain 100-fold in mice. Find out more...

Slime proves valuable in developing method for counting salmon in Alaska

Thu, 03 Jan 2019 13:36:31 EST ~ Scientists have published a novel method for counting Pacific salmon -- analyzing DNA from the slime the fish leave behind in their spawning streams. Find out more...

Fish bones yield new tool for tracking coal ash contamination

Wed, 26 Dec 2018 16:40:43 EST ~ A new study shows that trace elements found in fish ear bones can be used as biogenic tracers to track coal ash contamination. Strontium isotope ratios in the otoliths of fish collected from two lakes that received coal ash effluents matched strontium isotope ratios in contaminated pore water samples from the lakes' bottoms. This marks the first time strontium isotope ratios have been used as fingerprints to track coal ash's impacts in living organisms. Find out more...

Electric fish in augmented reality reveal how animals 'actively sense' world around them

Fri, 21 Dec 2018 12:39:29 EST ~ Researchers have used augmented reality technology to unravel the mysterious dynamic between active sensing movement and sensory feedback. Find out more...

Salmon may lose the ability to smell danger as carbon emissions rise

Tue, 18 Dec 2018 09:29:53 EST ~ New research shows that the powerful sense of smell Pacific salmon rely on for migration, finding food and avoiding predators might be in trouble as carbon emissions continue to be absorbed by the ocean. Find out more...

Conservation success depends on habits and history

Mon, 17 Dec 2018 15:15:21 EST ~ The ghosts of harvesting can haunt today's conservation efforts. Conserving or overharvesting a renewable resource like fish or other wildlife is often determined by habits and past decisions, according to a study that challenges conventional expectations that the collapse of fast-growing natural resources is unlikely.
