Donating to the Museum
As with all fish in the, the king salmon can be donated to the museum aquarium by talking to Blathers, who will follow up the donation with a small talk about it. In, it can be found in the top-most tank. In, it can be found in the middle-right tank.

In
Blathers will say this upon the donation:

"The king salmon will swim upstream to spawn, as most people know... What many DON'T know, however, is that it eats nothing while en route! As such, when king salmon begin their journey at the mouth of a river... They're all fatties! Think upon that the next time you eat an entire cake before working out, wot!"

In City Folk
Blathers will say the following upon the donation:

"...Hoo, quite impressive! This one put up quite a fight, I should think? The regal king salmon dwarfs lesser salmon with an overall length of up to 60 inches (130 centimeters), eh wot? Its size makes catching it with a net difficult, so most people rely on a fishing rod to catch the king!"

In New Leaf
"King salmon grow to about twice the size of regular salmon, which really helps them embody the name. This size essentially makes them the actual kings of salmon, though they are also called chinook salmon. In some regions, they return to the river in spring or summer and live there until spawning in the fall. In rare cases, king salmons' meat will be white, but these are not as popular since pink is the standard."

In New Horizons
Blathers will say the following upon donation:

"The king salmon didn't get its name for nothing. This stately fish can weigh in at up to 130 pounds! It's clear why it's referred to as the king of salmon. I imagine even the mightiest net can catch no more than a few at a time. I must say it's a miracle to me that you didn't get dragged out to sea by this one, wot!"
