When the player is donating it to the museum in, Blathers will say the following:

"Cherry salmon are known for their flavor and beauty, eh wot? Indeed, that is likely why they are called the queens of mountain-stream fishing. Hoo hoo! Of course, the males of the species might object to that moniker!"

"The first thing you notice when looking at a cherry salmon is undoubtedly its green, polka-dot body, wot? All those different sized dots overlapping each other... How very chic!"

"The spotted pattern on cherry salmon serves as a camouflage and is rather common in all salmon. Most cherry salmon spend their lives in rivers, but some do migrate to the ocean to fully mature. They are popular with anglers because of their well-balanced physique and beautiful patterns. Plus, their nervous nature makes them a good challenge to catch, which just adds to the fun."

When donating it to the museum in New Horizons, Blathers will say;

"The cherry salmon is related to the salmon, and is known for its distinctive pattern of "polka dots." Their polka dots disappear as they mature, but ONLY in the fish of certain geographic regions. Pity the poor researchers that must make sense of the cherry salmon's fickle fashion sense."

Real-world information
The masu salmon (sometimes called the cherry hybrid salmon), Oncorhynchus masou, can be found in the western areas of the Pacific Ocean, namely Japan and Korea. It has a landlocked sub-species called the Taiwanese salmon, found in Taiwan. It gets the name cherry salmon from the color it goes when it hits maturity, where the stripes on its sides develop a crimson tinge. It feeds mainly on insects, but also feeds on small fish and crustaceans. It is an endangered, harmless fish.
