Does current shellfish anti-predator gear curb "crunching" rays?
According to NOAA Fisheries, more than 80 percent of marine aquaculture production in the United States consists of bivalve mollusks such as oysters, clams and mussels. However, it's not just humans who enjoy eating these shellfish, so do marine rays.....»»
Scientists reveal molecular structure of bacterial gas vesicles
Similar in function to ballast tanks in submarines or fish bladders, many water-based bacteria use gas vesicles to regulate their floatability. In a new publication in Cell, scientists from the Departments of Bionanoscience and Imaging Physics now de.....»»
Warming and overfishing could switch the role of fishes in the marine carbon cycle
Bony fish are more often recognized as food sources than as carbon regulators. They provide an array of services relevant to climate change mitigation. For instance, they store carbon within their bodies as they grow and export it to deep seas throug.....»»
Breeders of new fish hope to tickle taste buds of salmon, cod and tuna lovers
Fish farming can make food supplies more stable while itself becoming more sustainable, according to researchers in Hungary and Norway......»»

How fish evolved to walk
When you think about human evolution, there's a good chance you're imagining chimpanzees exploring ancient forests or early humans daubing wooly mammoths on to cave walls. But we humans, along with bears, lizards, hummingbirds and Tyrannosaurus rex,.....»»
System-based habitat management of freshwater ecosystems benefits fish and people
Biodiversity is declining rapidly. Many conservation actions focus on single species. An alternative approach is to comprehensively improve ecological processes and habitats, thereby supporting entire species communities. This so-called ecosystem-bas.....»»
Why seagrass needs space
Seagrass: green leaves swaying in the currents. Fish weave their way through, and sea turtles graze. They're always on their guard, watching out for any encroaching sharks. The seagrass' roots are hidden in the seabed, where they anchor the sand, sec.....»»
"Chunky dunk?" Cleveland"s prehistoric sea monster may have been shorter, stouter than once believed
About 360 million years ago, in the shallow subtropical waters above what is now the city of Cleveland, an armor-plated fish many believed to be up to 30 feet long ruled the seas......»»
Young snapping shrimps" tiny claws accelerate in water like a bullet
When it comes to a quick draw, few creatures outgun adult snapping shrimp (Alpheus heterochaelis). They stun passing fish and foes with a simple click of a spring-loaded claw, which squirts a high-speed jet that rips through the water, producing a va.....»»
Shark from the Jurassic period was already highly evolved
Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were a.....»»
"Anti-social" damselfish are scaring off cleaner fish customers, which could contribute to coral reef breakdown
Damselfish have been discovered to disrupt "cleaning services" vital to the health of reefs, and climate change may mean this is only likely to get worse......»»

HP's dual monitor bundle for two units of the HP V28 4K monitor is on sale for just $450 for $310 in savings, but you need to hurry because stocks are limited......»»
Mediterranean hunter-gatherers may have relied on marine resources more than previously thought
New research has revealed humans living on the Mediterranean coast 9,500 years ago may have relied more heavily on a fish diet than previously thought......»»
New research reveals 12 ways aquaculture can benefit the environment
Aquaculture, or the farming of aquatic plants and animals, contributes to biodiversity and habitat loss in freshwater and marine ecosystems globally, but when used wisely, it can also be part of the solution, new research shows......»»
Urban ponds require attention to ensure biodiversity, shows study
Ponds are important part of urban green-blue infrastructure. They provide city dwellers with many ecosystem services, such as recreation and supporting biodiversity. Recreation, however, may conflict with supporting biodiversity. For example, fish in.....»»
Hi-tech is making the seas transparent
Researchers at James Cook University who paired a revolutionary method for detecting fish with freely available ecological data believe the technique could transform environmental science......»»
Tropical seagrass meadows are sand factories that could protect coral reef islands from sea-level rise
Seagrasses are flowering plants that form dense underwater meadows in coastal waters worldwide, from the frigid seas of the Arctic to the warm shallows of the Caribbean. These meadows provide a refuge for young fish, food for grazing sea turtles and.....»»
