The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.

That's the good news for the threatened species. The bad news: unfiltered stormwater killed almost all of them. The findings are consistent with previous research on adult and juvenile coho that found exposure to untreated roadway runoff that typically winds up in waterways during storms resulted in mortality of 60% or more. For the coho hatchlings in this study, mortality from runoff exposure was even higher at 87%. When the stormwater was run through a biofiltration method -- essentially layers of mulch, compost, sand and gravel -- nearly all the coho hatchlings survived, though many of resulting fish had smaller eyes and body sizes than a control group.

But one color-changing fish has evolved a clever way to keep watch on the parts of itself that lie outside its field of view -- by sensing light with its skin.

Now, researchers have a new approach for creating desirable vegan seafood mimics that taste good, while maintaining the healthful profile of real fish. They 3D-printed an ink made from microalgae protein and mung bean protein, and their proof-of-concept calamari rings were air-fried into a snack.

These areas are among the fastest warming ocean regions and are projected to increase between 1-6°C (+1-10°F) by the end of the century, a sign of climate-driven changes in marine ecosystems.

An autonomous mobile wave glider and passive acoustics were deployed to survey two marine protected areas on the western shelf of Puerto Rico to locate spawning aggregations of two commercially important species -- the Nassau and red hind groupers. Findings show these sites are critical habitat for both species and multiple previously unknown grouper species, which highlight the importance of expanding existing seasonal regulations.

Along some highly populated areas on the shorelines of Hawai'i, wastewater pollution and urban runoff combine with fishing pressures to put immense stress on coral reefs.

The difference is likely a result of the trout adapting to the food sources of the once-fishless high-mountain lakes -- a change that has taken place in a relatively short period of time and at a rate that is generally consistent with the historic timing of stocking for each of the lakes.

Instead, these sharks keep the core regions of their bodies warmer than the water like the most athletic swimmers in the sea such as great white sharks, mako sharks and tuna.

This phenotypic plasticity has been shown to be expressed by a variety of factors, including predator type, predator mode, and density. Overall, the small and medium-sized Daphnia expressed the highest degree of predator-induced plasticity, which the team found was more evident in small Daphnia than would be expected from size-selective predation.

Not only do directly mined areas become less habitable for ocean animals, but mining also creates a plume of sediment that can spread through the surrounding water. An investigation on the environmental impact of this first test reports a decrease in ocean animals both in and around the mining zone.

Unlike heatwaves on land, periods of abrupt ocean warming can surge for months or years. Around the world these 'marine heatwaves' have led to mass species mortality and displacement events, economic declines and habitat loss. New research reveals that even areas of the ocean protected from fishing are still vulnerable to these extreme events fueled by climate change.

Selecting the gregarious Goliath grouper, researchers deployed a novel automated detector and localization model to find underwater marine organisms using their low-frequency pulse sounds. Although passive acoustics has shed light on fish habitat preference as well as their movements, no studies have been able to illustrate their detailed behavior, until now. Classifying sounds produced by fish will help to understand how they respond to environmental changes and anthropogenic disturbances.

Sea lice are parasitic copepods (small crustaceans) found in many fresh and saltwater habitats, and have been implicated in the decline of wild salmon populations. The research sheds greater light on the types of viruses being carried by sea lice, and how the viruses and host are interacting.

Time-restricted fasting is an eating pattern where people limit their food consumption to certain hours of the day. It's a popular health and fitness trend and people are doing it to lose weight and improve their health. But the new study shows that time-restricted fasting affects reproduction differently in male and female zebrafish. Importantly, some of the negative effects on eggs and sperm quality can be seen after the fish returned to their normal levels of food consumption. The research team say that while the study was conducted in fish, their findings highlight the importance of considering not just the effect of fasting on weight and health, but also on fertility.

They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.

Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that the body can both induce it and shut it down naturally without medication. The health advantages of natural fever to humans still have to be confirmed through research, but the researchers say because the mechanisms driving and sustaining fever are shared among animals, it is reasonable to expect similar benefits are going to happen in humans.

Now, researchers in Australia think they may have found evidence of this behaviour being described in ancient accounts of sea creatures, recorded more than 2,000 years ago. They believe that misunderstandings of these descriptions contributed to myths about medieval sea monsters. Whales are known lunge at their prey when feeding, but recently whales have been spotted at the surface of the water with their jaws open at right angles, waiting for shoals of fish to swim into their mouths. A clip of this strategy was captured in 2021 and went viral on Instagram. This strategy seems to work for the whales because the fish think they have found a place to shelter from predators, not realising they are swimming into danger. It's not known why this strategy has only recently been identified, but scientists speculate that it's a result of changing environmental conditions -- or that whales are being more closely monitored than ever before by drones and other modern technologies.

What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the 'bony-tongues' or the 'eels', was the oldest. A study has just put an end to the debate by showing through genomic analysis that these fishes are in fact one and the same group, given the rather peculiar name of 'Eloposteoglossocephala'. These results shed new light on the evolutionary history of fish.

Unfortunately, spawning Chinook salmon are increasingly younger and concentrated within fewer age groups, with the oldest age classes of spawners rarely seen in recent years. The new findings suggest changes in hatchery practices and fishery management could help restore the age structure of the salmon population and make it more resilient to climate change.

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.

A recent study quantified the lipid content in Fraser River Chinook salmon -- the southern resident's preferred meal -- and found that spring-run Chinook salmon, the earliest to arrive to the Salish Sea are lipid-rich and energy dense; a critical factor for the killer whales who prey on them. Fraser River Chinook salmon that come later in the season have lower energy density.

A new study helps to explain this paradox. The researchers discovered that the ability of fish in temperate and polar ecosystems to transition back and forth from shallow to deep water triggers species diversification. Their findings suggest that as climate change warms the oceans at higher latitudes, it will impede the evolution of fish species.
