95% of fish are ‘dark fish’

If scientists have indeed got this correct, it’s an incredible finding.

Fish in the sea

Prof Duarte led a seven-month circumnavigation of the globe in the Spanish research vessel Hesperides, with a team of scientists collecting echo-soundings of mesopelagic fish.

He says most mesopelagic species tend to feed near the surface at night, and move to deeper layers in the daytime to avoid birds.

They have large eyes to see in the dim light, and also enhanced pressure-sensitivity.”

They are able to detect nets from at least five metres and avoid them,” he says.”

Because the fish are very skilled at avoiding nets, every previous attempt to quantify them in terms of biomass that fishing nets have delivered are very low estimates.”

So instead of different nets what we used were acoustics … sonar and echo sounders.”

Lobsters and octopuses are sentient and feel pain

I stopped eating meat in November 2017 but, until February of this year, was still eating fish (including lobster and other shellfish).

That changed when, over dinner, our sporty 14 year-old son, who stopped eating meat just before the start of the pandemic, asked why he and I still ate fish if we didn’t eat animals?

We stopped there and then. Once you’ve seen something like My Octopus Teacher, I don’t know how I ever saw such creatures as food.

Octopus

The Animal Welfare (Sentience) Bill recognises animal sentience – which is the capacity of animals to have feelings, including pain and suffering.

It currently says fish, and other vertebrates which feel pain, should be protected as much as possible.

Animals like lobsters and octopus are not currently protected by the bill because as invertebrates, their body is different to ours, so they aren’t thought to have those complex feelings, says a report by the Conservative Animal Welfare Foundation (CAWF).

The report says arguments against recognising these species focuses on physical differences between these animals and humans – but this fails to understand what it means for an animal to have feelings.

It says those species “undoubtedly experience the world in extremely different ways to ourselves,” but what matters is whether they feel pleasure and pain.

How to Be at Home (2020)

🌐 The Metaverse is coming — “Over the course of 2021, the Metaverse will experience widespread use, and start to become a human co-experience utility. People will meet in virtual worlds not just to play a game, but also to check out a new movie trailer or laugh at user-generated videos. Education will move from learning to code online to learning core sciences with physics or biology simulations and ultimately becoming an immersive environment where classrooms are organised within it.”

🐠 Hallucinogenic fish — “A few reporters have eaten the dream fish and described their strange effects. The most famous user is Joe Roberts, a photographer for the National Geographic magazine. He broiled the dream fish in 1960. After eating the delicacy, he experienced intense hallucinations with a science-fiction theme that included futuristic vehicles, images of space exploration, and monuments marking humanity’s first trips into space.”

Hundreds of Google Employees Unionize, Culminating Years of Activism — “The union’s creation is highly unusual for the tech industry, which has long resisted efforts to organize its largely white-collar work force. It follows increasing demands by employees at Google for policy overhauls on pay, harassment and ethics, and is likely to escalate tensions with top leadership.”

🍌 The Banana Trick and Other Acts of Self-Checkout Thievery — “Perhaps it’s not surprising that some people steal from machines more readily than from human cashiers. “Anyone who pays for more than half of their stuff in self checkout is a total moron,” reads one of the more militant comments in a Reddit discussion on the subject.”
