OC Overview

New Genetic Research Shows the Legacy of Fish Farm Escapees

New tests have discovered interbreeding between escaped farm salmon and native salmon stocks in Newfoundland due to the 2013 Cooke Aquaculture pen collapse in that area. This was not the first, nor the last of pen collapses for Cooke Aquaculture. During the summer of 2017, where over 260,000 farmed salmon escaped into Puget Sound, Cooke stated that survival of the escaped fish was low and interbreeding was impossible. The same statements were given in 2013. Obviously those fish did survive and found a way to flourish. (via Hakai Magazine)

Angry at plight of southern-resident orcas, speakers rebuke NOAA in public meetings

With the most recent loss of J50, only 3 years old and one of the two females born in her generation, there is reason to be upset. NOAA officials have known about the plight of the residential whales for some time and the public feels they have not done enough with that knowledge. With the death of J50, and the too soon departure of J35’s calf, NOAA officials hope that only progressive change will come from this low point. (via Seattle Times)

Scientists Gave MDMA to Octopuses—and What Happened Was Profound

Dosed with a small amount of MDMA, octopuses display similar acts as expected by humans. When given to seven octopuses, the usually loner beings piled together showing affectionate touching and even “dancing”. This research suggests that our human brain chemistry and that of octopuses may be more alike than we previously thought. (via Gizmodo)
