Oh man, that really stinks

North of Bahía Tortugas, near the Malarrimo fish camp.

Sounds like an algae bloom depleting the dissolved oxygen.

I witnessed that in Zihuantanejo back in 1986, but on a much smaller scale!

i have noticed that one marine species takes a big hit, there are repercussions throughout the system.

According to that bastion of scientific research and accuracy, The Gringo Gazette (second only to Fox News), fishermen reported water temperatures of 30C, or 86 degrees Fahrenheit.

Yes, that could definitely cause a low-oxygen condition.

"The Gringo Gazette (second only to Fox News)" :lol:

.....it was right at 10 years ago we had the big fish die-off in Ventura harbor, small potatoes compared to this one!

It's hard to believe that the water temperature was 20 degrees or so (around 30%) warmer than normal. Even just considering surface temps.

Maybe.......

If the temperature was truly that much above the norm, it could cause serious problems all on it's own. Algae blooms also occur in Alaska waters that never get above the 50's.

In 2011 a massive school of sardines swam in to the harbor at Redondo Beach, resulting in a mass die off. It was concluded that the fish died because they used up all the oxygen in the water. This could be something similar, if they died in the lagoon and were then flushed out by the tide they would end up on the Malarrimo beach, the trash catcher of the Pacific.

In the Redondo Beach incident it was unclear why the sardines swam in to the harbor. It was speculated that they may have been chased by predators, or consumed a red tide plankton bloom offshore and became disoriented, or even that they sensed the earthquake in Japan.

Collect everything with a wheel loader and then build a fishmeal factory. Would be a kind of recycling.

Do you know if there was any forecast that Trump might win the 2016 election and that was causing the disorientation :lol:

Unlikely due to sardines poor reading skills.

But there are a lot of near brain dead humans suffering the ill effects of the oxygen deprivation in the trumpesphere. A virulent red algae brain bloom seems to have a grip on about 40% of Mexico's neighbouring north.
