Norway tried to block it but had to give in. This could seriously complicate their #Arctic mining plans. 👏

Deep-dive dinners are the norm for tuna and swordfish, MIT oceanographers find
MIT oceanographers discovered big fish like tuna and swordfish get a large fraction of their food from the ocean’s twilight zone — a cold, dark layer about half a mile below the surface.

Wow. Atlantic cod are wild fish whose population should be determined by ocean conditions, prey availability + other nature-driven phenomena.
But instead, FOR *AT LEAST* 600 YEARS, fishing has been the main variable determining how many/what sizes of cod there are. Amazing paper.

Using light to attract + catch marine species isn't new - massive squid fisheries depend on this - but we didn't know til now that this works for scallops.
Fascinated to see how this method competes with dredging on yield/cost/efficiency as it's clear on environmental impact, this wins hands down.

The frustrating thing is that the paper specifically recognizes that “lost yield” may be due to a specific policy choice to preserve ecosystem health, i.e. Menhaden in the US, but still chooses to “penalize” the US for that choice.

Interesting to see Norway (a prolific forage fishing nation) trying to better protect seabirds with minimal focus on fisheries impacts such as prey depletion. Northeast Atlantic seabirds desperately need better domestic/international forage fish management: for herring, sprat, sandeel, mackerel etc.

Still hope for coral reefs. Using 28-years of data in Seychelles, we find reefs recovering 4-5 years faster from the 2016 bleaching event, than they did after 1998. Also, a reef that had regime-shifted to macroalgae for over 15 years, is recovering to coral.
