Coles, Woolworths and Aldi ‘responsibly sourced’ salmon labels may be misleading, watchdog told

Posted on by

Environmental groups allege some of the supermarkets’ salmon is from Tasmanian farms reportedly having ‘catastrophic’ impact on ancient Maugean skate

Major supermarkets may be misleading consumers that their salmon products are responsibly sourced as some is produced in Tasmanian farms that are “far from sustainable”, environmental groups say.

The Environmental Defenders Office, acting on behalf of four environmental groups, has made a complaint to the consumer watchdog, urging it to investigate whether “responsibly sourced” labelling on seafood products and promotional material used by Coles, Woolworths and Aldi have broken consumer law by misleading consumers.

The climate crisis, invasive species, overexploitation of resources and pollution could break down crucial ecosystems. We asked experts to lay out the risks and offer some solutions

The continued destruction of nature across the planet will result in major shocks to food supplies and safe water, the disappearance of unique species and the loss of landscapes central to human culture and leisure by the middle of this century, experts have warned.

By 2050, if humanity does not follow through on commitments to tackle the five main drivers of nature loss critical natural systems could break down just as the human population is projected to peak.

Ethical concerns over sustainability and welfare have seen venues offering new choices to ubiquitous ‘chicken of the sea’

Salmon has undergone a rapid transformation in recent decades. Once a special treat, it is now ubiquitous. From drinks reception canapés to wedding functions, Christmas smoked salmon or simply wrapped in foil and baked on a week night, salmon is everywhere.

Scotland is world renowned for salmon production, and the fish makes up 40% of its total food exports; it is also Britain’s most valuable food export. Healthy, low in saturated fats and high in omega-3, salmon is a success story.

The 90-100F readings add to previous warnings over warming water putting marine life and ecosystems in peril

The surface ocean temperature around the Florida Keys soared to 101.19F (38.43C) this week, in what could be a global record as ocean heat around the state reaches unprecedented extremes.

A water temperature buoy located in the waters of Manatee Bay at the Everglades national park recorded the high temperature late on Monday afternoon, US government data showed. Other nearby buoys topped 100F (38C) and the upper 90s (32C).

Fears biodiversity proposals could be abandoned amid opposition from lobby groups and some countries

MEPs have been accused of whipping up “a culture war against nature” after the fisheries and agriculture committees voted against the EU’s biodiversity restoration law.

Last June, the European Commission revealed proposals for legally binding targets for member states to restore wildlife on land, in rivers and the sea. The nature restoration law was announced alongside separate legislation proposing a crackdown on chemical pesticides with the aim of reversing the catastrophic loss of wildlife on the continent.

Releasing environmental water held downstream could help stem the spread of poor quality water, experts say

A “wall of dead fish” spanning tens of kilometres is moving along a stretch of the Darling-Baaka river near the town of Menindee, with temperatures forecast to reach 41C in the area on Saturday.

“The smell is just next level,” resident Graeme Crabb said. “Imagine the smell if you put a dead fish in your sink and let it rot for a few days – but we have millions of them.”

Catalonia launches operation to clear fish from reservoir to save drinking water

Posted on by

Focus is on Sau reservoir, where water supplies have plunged to their lowest level since 1990

Officials in Catalonia have launched what is being described as an extraordinary operation to clear as many as 1.5 tonnes of fish a day, including many invasive species, from a rapidly dwindling reservoir in the hopes of salvaging drinking water as drought continues to grip the region.

The operation is focused on the Sau reservoir, a sprawling body of water flanked by mountains and tree-covered hills about 60 miles north of Barcelona, where water supplies have plunged to their lowest level since 1990.

Scientists hope emerging research into new types of animal feeds will make aquaculture more sustainable

Most of the environmental effects of farmed chicken and salmon arise from the food the animals are reared on, new research suggests.

Animal feed given to farmed chickens and salmon account respectively for at least 78% and 69% of the industries’ environmental pressures, according to a study published in the journal Current Biology.

Study also says eating one serving of fish with PFAS could be equivalent to drinking contaminated water every day for a month

Wild caught, freshwater fish in the United States are far more contaminated with toxic PFAS “forever chemicals” than those commercially caught in oceans, and the highest levels are found in fish from the Great Lakes, a new analysis of federal data suggests.

The peer-reviewed study by public health advocate Environmental Working Group (EWG) also found eating one serving of US freshwater fish contaminated with median PFAS levels could be equivalent to drinking highly contaminated water every day for a month.

Carp spawning event fills Murray-Darling flood waters with masses of flailing fish

Posted on by

Experts say while boom in invasive species is not good news for some native fish, there will be winners – including water birds

In creeks, rivers and flood waters across the Murray-Darling Basin, an uncountable and unfathomable number of invasive carp are turning waters into bubbling masses of flapping and flailing fish.

“It’s quite a sight,” said Dr Matt Herring, an environment consultant. “I walked through one of the schools of carp a few days ago and it’s the first time I’ve trodden on fish with every step.”

Scientists fear an ecological disaster is playing out in parts of the river because of ‘alarmingly’ low dissolved oxygen levels

Stretches of the Murray River could become an “ecological desert” because widespread flooding has reduced water quality, a scientist has warned, as New South Wales communities rally to save fish populations.

Dr Ian Wright, a professor at Western Sydney University’s School of Science, believes fish and other aquatic wildlife are dying in huge numbers along the river as dissolved oxygen levels plummet – and the ecological impact could be “catastrophic”.
