What really makes fish become sexually active
Discounting anthropogenic-induced changes, the seasonally oscillating environments where long-lived fish hatch and grow remain more or less the same throughout the course of their lives. This means that the common explanation that states that fish be.....»»
Simulations of swimming fish suggest fish may naturally prefer to compete—not cooperate—during swimming
Researchers have shown how different swimming formations may save fish energy and suggest that they only switch positions to save energy for the group when under pressure......»»
Highly sensitive fiber optic gyroscope senses rotational ground motion around active volcano
Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, Italy. A better understanding of the seismic activity.....»»
Collapse in migratory fish populations threatens health of millions and critical freshwater ecosystems
Populations of migratory freshwater fish species—including salmon, trout, eel, and sturgeon—continue to decline across the globe. This decline risks the food security and livelihoods of millions of people, the survival of countless other species,.....»»

Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study......»»
Ancient DNA from an extinct native duck reveals how far birds flew to make New Zealand home
Ask a bird lover if they have heard of the extinct giant moa or its ancient predator, Haast's eagle, and the answer will likely be yes. The same can't be said of New Zealand's extinct, but equally unique, mergansers—a group of fish-eating ducks wit.....»»
California bans salmon fishing for the season in Sacramento-area rivers and Klamath basin
The California Fish and Game Commission has voted to ban salmon fishing in the Sacramento, American, Feather and Mokelumne rivers......»»
Endangered migrating eagles impacted by Ukraine war, new study shows
A new study reveals for the first time the impact of ongoing conflicts on the migration of an endangered bird species. The paper "Active European Warzone Impacts Raptor Migration" was published in Current Biology on May 20......»»

Researchers discover new family of bacteria with high pharmaceutical potential
Most antibiotics used in human medicine originate from natural products derived from bacteria and other microbes. Novel microorganisms are therefore a promising source of new active compounds, also for the treatment of diseases such as cancer or vira.....»»
Study demonstrates self-similar fractal stress is more suitable for destructive scenario earthquake simulation
Scenario earthquakes are useful in assessing earthquake hazards along active faults. However, determining the sources of destructive scenario earthquakes, particularly when dealing with heterogeneous stresses, can be challenging......»»
Investigating the poisoning effect of carbon deposition during CO₂ electroreduction
A research team has proposed new understandings of the poisoning effect of carbon deposition during carbon dioxide reduction reaction (CO2RR) on the active sites of Cu electrode. The study was published in Precision Chemistry......»»
More than a dozen gigantic, decades-old fish removed from Colorado pond
Colorado Parks and Wildlife officials removed 14 massive, invasive carp from a pond at an Arvada park last week, more than 30 years after the fish were introduced as part of a national study......»»
Angling fish for food: Study finds recreational fishing accounts for 11% of reported harvest in inland fisheries
Rod and reel fishing is much more than a recreational activity: It makes an important contribution to the diet in many regions of the world. This is shown by an international team of researchers, including Robert Arlinghaus, Professor for Integrative.....»»

Genetic study finds early summer fishing can have an evolutionary impact, resulting in smaller salmon
Atlantic salmon are caught by fisheries when the fish are migrating to spawn. A new study led by the University of Helsinki explored how salmon caught at different times during their spawning migration differ from each other genetically. The study on.....»»
Scientists find ancient, endangered lamprey fish in Queensland, 1400 km north of its previous known range
The Australian brook lamprey (Mordacia praecox) is part of a group of primitive jawless fish. It's up to 15 cm long, with rows of sharp teeth. Surprisingly, it doesn't use these teeth to suck blood like most lamprey species—it's non-parasitic......»»
