Rainbow Trout Modified by Humans to Continuously Lay Salmon Eggs

Tokyo University of Marine Science and Technology has successfully made rainbow trout repeatedly lay salmon eggs by transplanting salmon cells into them. This breakthrough is expected to improve the efficiency of salmon farming and help in resource conservation.





Salmon usually spawn only once in their lifetime, but by transplanting salmon cells into rainbow trout, the research group at Tokyo University of Marine Science and Technology has succeeded in making rainbow trout repeatedly lay salmon eggs. This is expected to be beneficial for the efficiency of salmon farming and resource conservation.

Wow

It's safe since the difference is just between the Salmonidae family, Salmo genus and the Salmonidae family, Oncorhynchus genus.

Honestly, this is super efficient industrially.

Rainbow trout is tasty, so if we can get a lot, they should just sell it in the market. Stupid fishing cooperatives.

It's just good among river fish, not that delicious. Same goes for char and yamame. You can only grill them with salt or make them into meunière.

Yosanu Salmon

The salmon born this way don't lay eggs multiple times, they're just normal salmon.

Did the rainbow trout agree to lay salmon eggs? 😢

Lay! Lay the salmon eggs!

Reality is stranger than fiction, as always.

This is dignity destruction.

All-you-can-eat ikura!

Are humans the real aliens?

Making rainbow trout lay salmon eggs repeatedly... It's kinda...

What if one accidentally escapes? That could be a big problem.

If they escape and lay salmon eggs, isn't that fine?

>>48
Didn't they release a bunch of fish that were not naturally occurring hybrids before?

It was a hybrid between cherry salmon and rainbow trout.

They released the developed "Nijisakura" into the river; the prefecture advised not to release them into the wild.

Does this mean ikura will get cheaper?

Many of the so-called "XX Salmon" are improved varieties of rainbow trout.

🐟 "Nooo😭 I don't want to lay salmon eggs😭"

If I can eat salmon cheaply, who cares about ethical values.
