Berufsfischer fangen weniger Felchen

Mit rund 135 Tonnen Fisch haben die Berufsfischer am Untersee und Rhein im Jahr 2016 rund 4,5 Tonnen weniger gefangen als 2015. Der Rückgang beim Gesamtfang gegenüber dem Vorjahr liege vor allem am Einbruch bei den Felchenfängen, erklärte Werner Keller, der zweite Vorsitzende des Fischereivereins Untersee und Rhein, bei der Hauptversammlung im Hotel-Restaurant Mohren auf der Insel Reichenau. Vom sogenannten Brotfisch, der zwei Drittel des Gesamtfangs ausmacht, wurden 2015 knapp 100 Tonnen gefangen, im Jahr 2016 aber nur rund 88 200 Kilo – ein Rückgang von über elf Prozent.

Insekten: Ein Kahlschlag geht durchs Land

In weiten Teilen Deutschlands ist die Insektenpopulation um bis zu 80 Prozent eingebrochen. Vor allem Wildbienen, Hummeln, Schwedfliegen sowie den Tag- und Nachtfaltern drohe das schleichende Aus, mahnt Thomas Mitschke. „Allein die Rote Liste der Bienen umfasst 300 Arten.“ Der Vorsitzende des Naturschutzbundes Lüneburg ist Hummel-, Wespen- und Hornissenbeauftragter für Stadt und Landkreis Lüneburg.

Uitgestorven soorten terugbrengen heeft een hoge prijs

De biodiversiteit neemt eerder af dan toe wanneer we uitgestorven soorten weer tot leven gaan wekken. Daarvoor waarschuwen Australische onderzoekers in het blad Nature Ecology and Evolution. Ze wijzen erop dat het tot leven wekken van uitgestorven dieren hoge kosten met zich meebrengen. Dat geld moet natuurlijk ergens vandaan komen en de onderzoekers zijn bang dat het uit het spaarpotje ter behoud van bedreigde diersoorten wordt gehaald. En dat zou verstrekkende gevolgen hebben, zo tonen ze in hun studie aan.

At least 45 lochs around Scotland’s coast have been contaminated by toxic pesticides from fish farms

At least 45 lochs around Scotland’s coast have been contaminated by toxic pesticides from fish farms that can harm wildlife and human health, according to data released by the Scottish Environment Protection Agency (Sepa). Levels of chemicals used to kill the sea lice that plague caged salmon have breached environmental safety limits more than a hundred times in the last 10 years. The chemicals have been discharged by 70 fish farms run by seven companies.

Orcas of the Salish Sea on track to extinction

As Minister for Fisheries and Oceans Dominic LeBlanc makes announcements on Canada's West Coast this week, and with World Whale Day approaching (February 18), WWF-Canada calls upon the federal government to release its recovery plan for the Southern Resident Killer Whales (SRKWs). The action plan for their recovery under the Species At Risk Act (SARA) is long overdue, and unless strong protection measures are quickly implemented, it is unlikely this group will survive in the long-term.

The Terminator ( Homo exterminans )

While many people will be little moved by the loss of ‘creepy crawlies’, a massive extirpation of insects spills over to affect the numbers of birds, frogs, reptiles and fish that rely on insects as food, and the decline of these in turn affects larger animals. It impairs the successful pollination of plants which provide up to a third of the world’s food supply, as well as the renewal of landscapes and forests. Modern plants have evolved largely to depend on insects to fertilise them: lose insects and the whole web of life attenuates and, in some cases, collapses.

Fishermen blame pollution for Lake Victoria fish decline

Fishermen in Lake Victoria have expressed concerns over a possible extinction of the Tilapia Species due to high levels of pollution in the lake. They said that a catch on the species has been on a steady decline as various institutions around the lake continue to release untreated waste into the lake. The fishermen in Kisumu and Kendu Bay told the Standard that in the past few months, pollution on the Lake has been on an increase. They noted pollution always threaten the Tilapia species which swims to other regions in search of clean water.

As Trump’s EPA Takes Shape, Here’s Your Pesticide Cheat Sheet

In the final weeks and months of the Obama administration, the Environmental Protection Agency’s Office of Pesticide Programs issued a flurry of reports on some of the country’s most widely used pesticides. Decisions made on the basis of these environmental and health assessments will likely determine the level of pesticide residue allowed on the food we eat. They will affect children’s neurological health and development, particularly in agricultural communities. They will determine how farmworkers are protected from pesticide exposures.

Depleted fish stocks and a huge dead zone in the Bay of Bengal signal a tipping point

The Bay of Bengal’s basin contains some of the most populous regions of the earth. No less than a quarter of the world’s population is concentrated in the eight countries that border the bay. Approximately 200 million people live along the Bay of Bengal’s coasts and of these a major proportion are partially or wholly dependent on its fisheries. For the majority of those who depend on it, the Bay of Bengal can provide no more than a meagre living: 61% of India’s fisherfolk already live below the poverty line. Yet the numbers dependent on fisheries are only likely to grow in years to come.
