I wonder what the survival rate is for these fishes

[–] [email protected] 160 points 20 hours ago (3 children)

According to the links in this post It's 95%-99% survival.

I wonder what the "fuck that hurt" rate is for these fishes

[–] [email protected] 13 points 13 hours ago

...that sounds to me like "survive the fall" more than "survive the week"

[–] [email protected] 55 points 20 hours ago (7 children)

Then why can't I yeet a bunch of goldfish

Try to fly higher above the tank and see if it helps

One of the bigger reasons has to do with the square cube law - as the size of something increases, surface area increases by a factor of 2 but mass increases by a factor of 3, so little fishes have a surface area-to-mass ratio that is quite a bit higher than a larger fish, and they're more susceptible to abrupt changes in temperature.

Kinda like how an ice cube will melt a lot faster than a big slab of ice, the core temperature of some small fish like a goldfish is gonna change more rapidly than the core temperature of a big fish like a trout so they tend to be a lot more finnicky in regard to significant and instantaneous changes to temperature and stuff. A larger fish might shrug off a significant change because it affects them more slowly, but that might be a totally wild an overwhelming experience for a little fish to go through

I'm confused though. Don't people use this to talk about how small things like bugs can fall from a large height and be uninjured, but large things like a human or elephant will be injured if falling from a height? I feel like what you're saying is backwards to what the internet has told me.

The math actually works, and is quite simple. Just assume the fish is a sphere

As opposed to the high friction vacuums we are used to.

IMMA YEET THEM SO FAR

[–] [email protected] 48 points 18 hours ago (1 children)

something i love about Lemmy is that on the drop of a hat someone is willing to calculate the "surface area to fish ratio"

[–] [email protected] 29 points 17 hours ago (2 children)

Problem is, you almost never know if that's actually true or complete bullshit.

It seems plausible, but killing virgins for rain also seemed plausible back then in the 70s.

"But it has rained, hasn't it?" Smug look

An example of why arguing with idiots is impossible to win.

[–] [email protected] 7 points 14 hours ago

The 70s was a wild time.

And in a similar but completely different way, the fish are being added to massive bodies of water. Home aquariums are minute in comparison, so they can't balance out chemical swings as easily and are much more prone to higher levels of nitrites and other toxic chemicals. The larger the body of water, the more stable the water quality.

[–] [email protected] 22 points 19 hours ago (3 children)

So what I hear you saying is I need a bigger aquarium...

[–] [email protected] 6 points 17 hours ago (1 children)

You could probably air drop one goldfish into a 100 gallon tank and it'd be fine (assuming it survived the fall).

[–] [email protected] 6 points 16 hours ago
[–] [email protected] 4 points 17 hours ago

And a bigger fish

[–] [email protected] 24 points 19 hours ago

You always need a bigger aquarium

[–] [email protected] 25 points 19 hours ago (1 children)

You can yeet goldfish. Carp are stupid tough. It's the tropical fish we often keep that are kinda wimpy. Also, they're not coming from a super healthy environment (the store) to our tanks.

[–] [email protected] 2 points 13 hours ago (1 children)

I would watch carp throwing as a competitive sport, they aren't going to make it easy

[–] [email protected] 2 points 12 hours ago (1 children)
[–] [email protected] 1 points 11 hours ago

I definitely have not, and now I have. I'm unsure if I should thank you for this or not.

I feel like it takes the sport out of it if the fish is dead though. The whole sport of the carp throwing is that a carp absolutely can kick a grown man's ass and flop to freedom if he isn't careful. You leave a carp alone long enough and those things turn into damn near coelacanths. They'll eat your dog. Manhandling one of those suckers into a parabolic arc is going to take skill, strength, planning, and luck.

Maybe 95% survive, but how many are injured in a way that might impact their quality of life?

Since these are being dropped specifically for the purpose of being caught and killed asap, quality of life might not matter.

For your sad little goldfish, please be gentle!

[–] [email protected] 2 points 12 hours ago

My understanding is these are juvenile fish that will be caught as adults, so they will live for a while.

[–] [email protected] 17 points 19 hours ago

Also, gotta think about whether 5% mortality rate is acceptable.

For an airdrop number of pond fish? Sure!

For your hobbyist number of expensive fish? Absolutely not

Have a pilots license?
