In Port Angeles, Washington State, USA a rare wildlife success story is taking place. The first wild steelhead trout has been seen in 100 years, since the construction of the Elwha and Glines Canyon dams. Efforts by government scientists and members of the Lower Elwha Klallam tribe to repopulate fish in the Elwha river (previously obstructed by the dams) have included releasing coho salmon and steelhead trout into the wild. But what surprised them most was not spotting the released fish, but discovering a wild steelhead that had found its own way to the previously cut off territory. In September,…

I first heard about the Salton Sea via a couple of documentaries focusing on pollution and economic collapse. One, VBS TV’s ‘TOXIC Imperial Valley’ shows the Salton Sea and surrounding area as a polluted wasteland populated by a few rugged individualists, stragglers and diehards. The millions of fish in the Salton Sea are dying off and the once playground for California’s rich and famous is now some kind of post-apocalypse Mad Max landscape dotted with abandoned tourist traps as well as a derelict military base. Honestly, it’s just the kind of thing that gets my imagination running. But are things…

Fishermen in Germany are blaming swimmers for peeing in a lake near Hamburg, resulting in the deaths of some 500 fish. The fishermen contend that the large amount of phosphates contained in urine have caused large amounts of algae to grow, suffocating many fish. Though there may be a scientific basis to the fishermen’s anti-bathers claims, Hamburg’s Urban Development and Environment Authority (BSU) contends that it’s ice skaters who are at fault. From The Local: The ice-skaters make a noise that wakes the fish out of hibernation. Then they can’t breathe and freeze. That’s a very common phenomenon. –BSU spokeswoman…

Species: Southern bluefin tuna (Thunnus maccoyii) Status: Critically Endangered (CR) Interesting fact: The southern bluefin tuna is one of the largest bony fish in the world, growing up to 4.3 metres long! The southern bluefin tuna is an incredibly streamlined and powerful fish capable of reaching speeds of up to 70 km per hour through the water. Swimming together in shoals, the southern bluefin tuna migrates vast distances from the spawning grounds in the Indian Ocean to the feeding grounds in colder, southern waters. During the spawning period, a mature female will produce several million eggs. Southern bluefin tuna are opportunistic…

In some coastal areas climate change means a rise in sea levels, leading to an increase in water salinity, which in turn means a high salt content in soil. Increasing salinity in fresh water and soil poses problems for agriculture and fish farming. This is a particularly tricky aspect of climate change adaptation, but coastal communities as well as scientists are finding ways to cope. Hardy varieties of rice, wheat and vegetables are one way, as is shifting from freshwater fish farming to raising saltwater species such as crabs. In Sri Lanka, rice farmers, together with the United Nations Development…

A beach in Nordreisa, Norway is now completely blanketed in dead herring. It is unknown what caused the herring to die; whether it was tides, predatory fish or something else. Scientists would like to test the dead fish to discover the cause of death. From the Guardian: For doom-mongers, the fish were the second a sign in as many days that 2012 would live up to the apocalyptic prediction of the ancient Mayans, after hundreds of blackbirds reportedly dropped dead in Arkansas. To see a large picture of the starling scene check out this article in the Daily Mail.

The global boom in sushi and overfishing have gone hand in hand for the last two decades. The tuna auctions, especially the Tsukiji in Tokyo, are a kind of Wall Street. There, each day, 2,000 tonnes of fish are sold, of which fifty of bluefin tuna are auctioned and sold at the price of gold. 80% of tuna caught and consumed in the world goes through Japan. Providing fresh seafood to industrialized countries has become a greedy business. Between 1995 and 2005, ten Mediterranean countries began to exploit their waters and soon after were joined by Japanese, Korean, Russian and South…

The Census of Marine Life is a 10-year worldwide project conducted by a network of researchers and coordinated in part by the Consortium for Ocean Leadership. The aim of the census – the first global study of its kind – is to ‘explain the diversity, distribution, and abundance of life in the oceans’. From an article in the Telegraph: They hope that by creating the first catalogue of the world’s oceans we can begin to understand the great ecological questions about habitat loss, pollution, overfishing and all the other man-made plagues that are being visited on the sea. The truth…

A new study from the UK’s Department for Environment Food and Rural Affairs (DEFRA) reports that the state of British seas has improved since the last report in 2005. Coastal waters are getting cleaner, fish stocks are improving and species diversity in estuaries is increasing, according to the most authoritative examination ever carried out of UK seas. –Guardian Yet despite these improvements, climate change is raising sea levels, temperatures and ocean acidity; and British coasts are trashier than ever – and they’re talking about litter, not the tackiness levels of seaside ‘resorts’ like Blackpool. The changing climate, along with European…

The history of this planet is an awesome thing to learn about and there are so many ways you can do that. You can go to a museum, read books, check out a historical reenactment event, or specialize in the hunt for fossils and other artifacts. Some people say history comes alive, but what if it never died in the first place? Australian scientists have stumbled upon an amazing find at Osprey Reef, which is part of the Great Barrier Reef. With the use of special low-light sensitive cameras, researcher Justin Marshall and his team discovered a number of prehistoric…

Eco-warrior and youngest air to a banking fortune, David de Rothschild set out in April on a well-publicized trip from California to Australia aboard a vessel constructed from recycled plastic bottles. The raft, christened the Plastiki, is set to arrive in Sydney in about two weeks time. The purpose of Rothschild’s journey: To draw attention to marine pollution – particularly from plastics – and the overfishing of the world’s oceans. Oceanographers estimate that there may be as much as 100 million tons of plastic suspended in the waters of the eastern garbage patch, a soup of plastic and other trash…

Yesterday was named ‘fish dependence day’ by the New Economics Foundation (NEF); marking July 9, 2010 as the date that Europe ate its fish quota for the year in terms of sustainability. A new analysis by the NEF entitled ‘Fish Dependence: The Increasing Reliance of the EU on Fish From Elsewhere’, highlights the unsustainable nature of the fishing industry in relation to Europe’s consumption. From yesterday forward, Europe will be in essence, living off of non-European fish. From a UK Press Association report: If the EU were only to consume fish from its own waters it would run out 189…

It’s been nearly 2 months since the Gulf Coast Oil Spill started. In that time, at least 783 birds, 353 turtles and 41 mammals have died. Unfortunately, the animal death toll may rapidly increase quite soon. Many animals are fleeing their natural habitat and coming closer to shore, where waters are less polluted. Dolphins and sharks are being found in shallow waters along Florida’s beaches; crabs, fish and rays are crowding around an Alabama pier; and oil-covered birds are venturing deep into the marshes—most likely looking for a safe place to die. Marine biologist, Larry Crowder, explained: “A parallel would…

While most of the country is currently obsessed with the Gulf Coast Oil Spill disaster, Utah residents have their own oil spill to deal with. Last week, a busted Chevron pipeline sent at least 400 to 500 barrels of oil into Red Butte Creek. The spill was initially at 50 gallons of crude oil per minute before crews were able to cap the leak. Many ducks and geese were coated in oil and a park also had to be shut down. What caused the leak or the extent of environmental damage is still uncertain; however, according to Chevron spokesperson, Mark…

The depletion of fish stocks in the world’s oceans and the use of increasingly sophisticated industrial fishing techniques are resulting in heavy damage to precious marine ecosystems. Trawling, once relegated to shallow waters with level sea floors, is now commonly used to fish deeper, including among coral reefs. Deep-sea trawlers use giant, heavy-duty nets that are dragged over the seafloor at depths of more than a kilometre. The nets are fitted with rubber rollers called “rock hoppers”, which destroy the corals that provide habitats for fish and other marine organisms. –Guardian According to a piece in the Guardian, scientific surveys…

Unseasonably cold weather in Florida this winter has had deadly consequences for the American state’s wildlife. Chilled iguanas are plummeting from their perches onto the freezing ground. Non-native tropical fish – both wild and kept in outdoor tanks at fish farms – are freezing to death. Burmese and African rock pythons have also been dying off – not an altogether unwelcome side effect of the cold weather for some. An article in the Guardian explains: Most of these invasive species – including pythons, iguanas, Nile monitor lizards and tropical fish – are either house pets or descended from house pets,…

I have a question for all the women out there who are either married or in some type of romantic relationship. Has your partner ever criticized (or punished) you simply because dinner was late or not to his/her liking? If so, it may interest you to know that certain fish species also go through similar situations. The Bluestreak Cleaner Wrasse is a fish that apparently needs a lesson in manners. This fish is known as a “cleaner fish”. They will clean parasites off larger marine animals, which is a win-win situation because the wrasse gets a free meal and the…

Sounds like a strange toy or home knick-knack, doesn’t it? Actually, this does apply to real fish, including eels and sharks. Scientists have discovered that the fish that are able to generate electric fields for purposes like fighting, navigating or mating, have a battery-like organ in their tails. Within this organ, a dimmer switch of sorts has been detected, as part of cells called electrolytes. The switch comes in the form of sodium channels. The fish uses these channels by inserting or removing them from the electrolyte membranes; the more channels that are used, the stronger the electric impulse will…

The latest “Red List of Threatened Species” by the International Union for Conservation of Nature reports that 1 out of 6 Mediterranean Mammals are in danger of being extinct. A total of 320 Mediterranean mammals (excluding dolphins and whales) were studied for the list. Not surprisingly, habitat loss and degradation were the top causes, brought about by “include expansion and intensification of agriculture, urbanization, infrastructure development, pollution and climate change.” One of the study’s co-authors, Helen Temple, called for awareness to stop the destruction of these species’ habitats “To ensure the survival of large herbivore and carnivore mammals in the…
