Fishing for herring, anchovy, and other “forage fish” in general should be cut in half globally to account for their critical role as food for larger species, recommends an expert group of marine scientists in a report released today. The Lenfest Forage Fish Task Force conducted the most comprehensive worldwide analysis of the science and management of forage fish populations to date. Its report, “Little Fish, Big Impact: Managing a crucial link in ocean food webs,” concluded that in most ecosystems at least twice as many of these species should be left in the ocean as conventional practice.
The decline of Caribbean coral reefs has been linked to the recent effects of human-induced climate change. However, new research led by scientists at Scripps Institution of Oceanography at UC San Diego suggests an even earlier cause. The bad news – humans are still to blame. The good news – relatively simple policy changes can hinder further coral reef decline.
After some good news about blue whales perhaps now there is also something hopeful to say about sharks. That however would still depend on whether we will be able to create and maintain protected areas in tropical reef systems along … Continue reading
Earth is a bit over 4.5 billion years old. Life on it is only about one billion years younger. And let´s say Homo smartphonensis is a mere three years old.
“In reserves off Spain and Italy, we found the largest fish biomass in the Mediterranean. Unfortunately, around Turkey and Greece, the waters were bare” – Enric Sala, National Geographic Society.
As if anthropogenic pollution and overfishing isn’t damaging enough for coral reefs worldwide, now certain seaweeds seem determined to see the end of reefs as well. These macroalgae produce chemicals that inhibit the growth of reef-building coral or even kill … Continue reading
75% of cut-the-fin-dump-the-dying-shark fishery is illegal. Many sharks also die as by-catch of conventional fishing. These sharks never reach the shore either – and their deaths are also not documented.
