Senegal looks to aquaculture as fish stocks dwindle
The Senegalese town of Kayar sits on the doorstep of the vast Atlantic Ocean, but it is a farm located further inland that provides part of its fish production......»»
Polar fish are less likely to die early, so they prioritize growth over reproduction
Polar fish experience lower mortality than tropical fish, allowing them to delay reproduction until later in life when they are larger and can produce more eggs, according to a study by Mariana Álvarez-Noriega at Monash University in Australia and c.....»»
River erosion can shape fish evolution, study suggests
If we could rewind the tape of species evolution around the world and play it forward over hundreds of millions of years to the present day, we would see biodiversity clustering around regions of tectonic turmoil. Tectonically active regions such as.....»»
Ivory Coast imposes fishing bans in bid to conserve stocks
West African fish exporter Ivory Coast on Thursday announced temporary bans on trawling for tuna and other species in a bid to protect dwindling stocks......»»
Computational model estimates lifespan of any fish species using only its genome sequence
If a fishery manager could only know one thing about a fish species, it should be lifespan. But many species live out their lives on time scales much longer than we can observe. And even the short-lived species do a good job of hiding in the sea......»»
What was behind Australia"s potato shortage? Wet weather and hard-to-control diseases
,If you've been into a fish and chip shop in the last 12 months, you may well have seen a notice tacked to the wall about the impact of the potato shortage. Supermarkets, too, slapped temporary limits on frozen chip purchases......»»
Spiny mice found to have bone-plated tails
Mammals are a bit odd when it comes to bones. Rather than the bony plates and scales of crocodiles, turtles, lizards, dinosaurs and fish, mammals long ago traded in their ancestral suit of armor for a layer of insulating hair......»»
Heat-stressed fish embryos can induce stress in nearby embryos
Heat-stressed fish embryos release chemical signals that change the appearance, behavior, and development of fish embryos that were not heat stressed, according to a study. Stress during development can change how an embryo grows and which genes are.....»»
ChatGPT on Wall Street Could Be Disastrous, Financial History Shows
Using artificial intelligence like ChatGPT to trade stocks and other financial instruments could have benefits—and perils.....»»
Slowing the aging of the intestine in fish slows the aging of the entire organism, discover scientists
Is it possible to extend lifespan by simply slowing the aging of an organ, such as the intestine? CNRS researchers have discovered how to extend the life expectancy of zebrafish by reactivating a gene within intestinal cells. The results were publish.....»»
Small, fast-growing reef fishes evolved in a warming ocean, finds study
James Cook University scientists have found coral reef fish developed faster growth rates in the warm oceans of the past, 50 to 60 million years ago. These small and fast-growing fishes epitomize the productive coral reefs of today......»»
New use for AI: Correctly estimating fish stocks
For the first time, a newly published artificial intelligence (AI) algorithm is allowing researchers to quickly and accurately estimate coastal fish stocks without ever entering the water. This breakthrough could save millions of dollars in annual re.....»»
In years after El Niño, global economy loses trillions
In the years it strikes, the band of warm ocean water spanning from South America to Asia known as El Niño triggers far-reaching changes in weather that result in devastating floods, crop-killing droughts, plummeting fish populations, and an uptick.....»»
Human crowds are best modeled by a "visual neighborhood"
Human crowd dynamics are best predicted by a visual neighborhood model, based on the visual fields of each person in the crowd. Birds flock, fish school, and human crowds, too, move in a collective motion pattern. Understanding human crowd behavior c.....»»
Crushed clams, roaming rays: Acoustic tags reveal predator interactions
Clam leases are designated underwater locations used to produce hard clams of all sizes from littlenecks to chowders. Clam production or aquaculture can be a risky business due in part to unwanted marine intruders. Among them, stealthy and highly mob.....»»
The Mystery of Fish Deaths in a Foul Chartreuse Sea
Researchers in Kotzebue, Alaska, are investigating why their town is increasingly playing host to harmful cyanobacteria......»»
Water warming study shows unexpected impact on fish size
The theory that aquatic animals such as fish will shrink due to global warming has been called into question by a study published today in eLife......»»
Can fish catch colds?
The simple answer to the question of whether fish can catch a cold is: no. This is because fish don't have lungs or a respiratory tract—or a nose to breathe through, for that matter. This is why you'll never see a fish with a hacking cough or a run.....»»

Factors affecting fish diversity patterns in middle and lower Yangtze River
Human-caused changes to landscapes and riverscapes have fundamentally impacted freshwater biodiversity patterns throughout the world's aquatic systems. Previous studies have shown that small- and medium-sized streams have experienced steep reductions.....»»
Lickable toads and magic mushrooms: Wildlife traded on the dark web is the kind that gets you high
