When was Pink salmon created?

Pink salmon were not "created" in the sense of being artificially bred or genetically engineered. They have existed in their natural form for millions of years.

It's possible you are thinking of a specific event related to pink salmon, such as:

* Selective breeding: While not technically creating a new species, fisheries management often involves selective breeding to enhance desired traits in salmon, like size or disease resistance.

* Aquaculture: Pink salmon are raised in aquaculture facilities, but this is a form of cultivation, not creation.

* A specific scientific discovery or experiment: If you have a particular event in mind, please provide more context about what you are interested in.

Please provide more information so I can assist you further.
