Was at a presentation a few years back by a toxicologist who'd figured out how to harvest eggs from a *live* sturgeon to make caviar, instead of killing the fish.…
But since live-harvested eggs are at a slightly different state of maturation than the kill harvest, you have to work with the eggs' own biology a little to get them to the membrane permeability that you need to make caviar. Or else instead of nice beads you wind up with slush.
I think some of that involved just adding a little calcium to the salt so the calcium triggers pores in the membrane to shut (which in the usual sturgeon cycle of life events, is triggered by fertilization).
Bottom line, the whole thing only works if you treat the egg as an active agent with its own biology & processes that it "wants" to do. Not a passive blob sitting & waiting for things to happen to it.
Doesn't escape my notice that it was a woman who invented it, & that the rest of the caviar industry thinks it's a complete abomination.

For a lot of reasons. Primarily "it's cool, threatens assumptions on what caviar is, & also they don't own it."
But lorrrrrd you should have seen the guys in the room who went up to her & gave her shit afterwards. One guy straight up wagged his finger in her face and said "I'm going to steal your patent from you." What the fuck dude.
It was kind of like being at one of those things where an orchestra performs a new piece for the first time and the audience RIOTS. Like. top hats & monocles flying. Completely surreal.
