If artificial light shines into the Arctic Ocean during the polar night, does it matter? A new paper in Communications Biology says the answer to this is a strong yes.
Raw materials from the sea
Omega-3 fatty acids are essential components of healthy diets for both humans and fish. The dramatic increase in fish farming worldwide has boosted the demand for omega-3 fatty acids so much that today’s supply can’t meet demand. Reducing waste and finding new sources can help.
The oceans are teeming with ever-increasing numbers of jellyfish. These squishy sea creatures can ruin fishing and discourage tourists. But one research group wants to turn this nuisance into pay dirt.
We need to know more, and teach more people, about aquaculture so we can use the ocean’s resources to the greatest extent possible while protecting the environment.
Excess CO2 in the atmosphere is making the oceans more acidic. Some studies show that’s bad news for fish, including commercially important species. But not all fish respond the same way.
The mysteries below the ocean’s surface have triggered human exploration and imagination for centuries. New marine robotics now make it possible to explore what goes on in the ocean depths.
We know that tiny marine creatures in the Arctic respond to weak light from the Moon or the northern lights during the polar night. Now researchers have learned that artificial light from research vessels can also have a negative effect.
Every year 340,000 tonnes of usable whitefish by-product are discarded into the sea. But the fisheries industry has now identified ways of halting this practice.
Representatives from Japanese and Norwegian universities, research institutions, government agencies and industries interested in polar issues will gather in Tokyo in early June to present research results and build partnerships.
