A very short microcast about reading by the light of a fish tank in the early hours of the morning.

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

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.
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.
