Egg-Protein Alternatives: Foods That Beat an Egg for Protein Power

Nutrition experts say a large egg’s ~6g of protein can be surpassed by a wide range of foods, with the top options per 3‑ounce serving including canned tuna (20–22g), salmon (20g), firm tofu (20g), shrimp (18–20g), and lentils (18g); other solid options are edamame, Greek yogurt, cottage cheese, dairy milk, quinoa, and pumpkin seeds. The article notes tuna’s mercury caution and highlights the benefits of diverse protein sources to cover all essential amino acids and other nutrients, alongside the 1.2–1.6 g/kg body weight daily protein guideline.

Rivers Reawaken: Nations Tear Down Hundreds of Dams to Restore Life

Rivers Reawaken: Nations Tear Down Hundreds of Dams to Restore Life

A European dam-removal surge in 2025 saw a record 603 dams and barriers removed across 21 countries, reconnecting more than 3,740 kilometers of rivers and enabling migratory fish like salmon to reclaim spawning grounds, with Finland’s Hiitolanjoki system and France’s Vezins cited; Sweden led removals with 173 barriers, and the EU’s Nature Restoration Regulation targets 25,000 km of rivers by 2030. While the benefits to biodiversity and flood resilience are clear, projects require years of planning, sediment management, and ongoing maintenance; the trend mirrors US successes on the Klamath and Elwha rivers, showing rapid ecosystem recovery once barriers come down.

Ancient Salmon Cans Hint at Ocean Health

Ancient Salmon Cans Hint at Ocean Health

A 42-year baseline study of 178 cans of salmon from the Gulf of Alaska and Bristol Bay found anisakid worms—parasites that require marine mammals to reproduce—are more common in chum and pink salmon from 1979–2021, while levels in coho and sockeye remained steady, suggesting a relatively healthy marine ecosystem and signaling that policies protecting marine life and water quality may be supporting ocean health.

Salmon Exposed to Cocaine Swim Farther, Signaling Environmental Drug Pollution

A study of 105 wild Atlantic salmon in Sweden’s Lake Vattern found fish exposed to cocaine and its metabolite benzoylecgonine swam about 1.9 times farther per week than unexposed fish, with the metabolite exposure adding roughly 7.6 extra miles — highlighting how pharmaceuticals in waterways are altering wildlife behavior and underscoring the need for improved wastewater treatment and monitoring, with related notes on sharks also ingesting drugs in other regions.

Wild Salmon Take a Longer Swim: Cocaine Metabolite Drives Greater Dispersal

Wild Salmon Take a Longer Swim: Cocaine Metabolite Drives Greater Dispersal

A multi-institution study exposed 105 juvenile Atlantic salmon in Sweden to cocaine or its metabolite benzoylecgonine and tracked their movement. Surprisingly, the metabolite had the strongest effect, with exposed fish swimming up to 1.9 times farther and ending up about 20 miles from release, suggesting cocaine pollution can alter wild fish behavior and ecosystem dynamics. The findings highlight that metabolites—often more prevalent in waterways—should be considered in risk assessments, and future work will assess how widespread these effects are and whether they impact survival and reproduction.

Cocaine in wastewater nudges salmon to roam farther, study finds

A Current Biology study in Sweden’s Lake Vättern found environmentally relevant levels of cocaine and its main metabolite benzoylecgonine in wastewater cause juvenile Atlantic salmon to swim up to 1.9 times farther per week and disperse up to about 12 km, with the metabolite sometimes having a stronger effect than the drug itself, highlighting that low concentrations of drug residues in waterways can alter wildlife behavior and potentially disrupt ecosystems.

Cocaine pollution may push salmon to roam farther, study finds

A two-month study in Lake Vättern found juvenile Atlantic salmon exposed to cocaine or its main metabolite benzoylecgonine swam longer distances and moved farther north than unexposed controls, with the metabolite causing the larger change. The results suggest drug pollution in rivers and lakes could alter salmon behavior and survival, highlighting the need for better wastewater management and greener medicines to reduce environmental risk.

Decades-Old Salmon Cans Offer a Time Capsule of Ocean Health

Decades-Old Salmon Cans Offer a Time Capsule of Ocean Health

Researchers analyzed 178 cans of salmon dating from 1979–2021, turning decades-old inventory into a 42-year ecological dataset by counting anisakid worms. The study found parasite numbers rose over time in chum and pink salmon (stable in coho and sockeye), suggesting reproduction and a functioning food web, while the data also illustrate how preserved cans can reveal long-term signals of ocean health in the Gulf of Alaska and Bristol Bay. Worms pose no risk to humans after processing.

Rare conjoined salmon twins found at Ontario hatchery prompt questions about early development

Rare conjoined salmon twins found at Ontario hatchery prompt questions about early development

Researchers at a Windsor-area freshwater hatchery documented two Chinook salmon fry that are ventrally conjoined—sharing a single yolk sac and blood vessels while each having separate heads and tails—raising questions about the limits of twin development in fish. The finding underscores how tiny embryonic disruptions can produce such rare twins and highlights the need for careful hatchery monitoring to inform Great Lakes stocking and future research.

Salmon, reimagined: experts rate the healthiest ways to enjoy the pink fish

The piece evaluates how different salmon preparations—raw (sushi/sashimi/poké), poached, smoked, baked, grilled, as well as dishes like fish pie, salmon burgers, en croûte, and tinned salmon—affect fat, calories and omega-3 content, noting skin-on can boost nutrients and moisture. It discusses safety considerations (parasite risks with raw fish and high salt in smoked salmon), pregnancy and NHS guidelines on weekly oily-fish portions, and highlights how pairing salmon with fiber-rich carbs and veggies can boost nutrient absorption and overall health.
