Which fish is least related to the other three?
This question is pretty hard, as it deals with the genus of the fish mentioned above. Although it is called a trout, rainbow trout (Oncorhynchus mykiss) belong to the genus Oncorhynchus, as do Chinook salmon (Oncorhynchus tshawytscha) and Coho salmon (Oncorhynchus kisutch). Atlantic salmon (Salmo salar) are in the same family (Salmonidae), but belong to a different genus (Salmo).

Got me. I reacted too quickly. I saw three salmon fish and automatically assumed they were the same without actually reading the question properly. 👍

Obscure, or what?

Seriously?? Again can we not have a standard level of difficulty for questions? Either they are very easy or designed to be so obscure that the majority can't answer correctly.

Yes, this question is pretty hard. It is deceiving.

While all of the so-called salmons are usually anadromous (spending their infancy in fresh water before migrating to salt water and then returning to fresh water to spawn and lay their eggs) there are populations of all the salmons that are landlocked and never enter a salt water environment. What is more, RainbowTrout frequently occurr in anadromous populations and mirgrate to salt water. A case in point are Steelhead of the Pacific Northwest. These are sea going RainbowTrout that migrate to the Pacific Ocean and then return to fresh water in order to spawn. See: https://en.wikipedia.org/wiki/Rainbow_trout or http://wdfw.wa.gov/fishing/salmon/steelhead.html

Looks like a year in the Seafood Department of Wiseway did nothing for me. :/

I recognized this as a trick question and deduced the correct answer… maybe there was some luck involved too.

Interesting question. Because of three salmon and one trout, I assumed it was the trout. Just goes to show, assumptions are the wrong answer

While I got it wrong, this was an excellent question.

I guessed the correct one because the other three are all native to the Pacific Northwest where I live

Tricky, but I got it. I live in the Pacific NW, and although I don't fish, I knew that the other 3 fish are all native to this area.

Ian MacBrown, While I almost declared my college major in forestry, I almost went for fisheries. Point being that I knew the answer through an interest pursued, not a degree (PhD or otherwise). 🤔

Melody Buchanan, I've caught rainbow trout that had white meat. I've also caught the same species that had nice pink meat. It just depends upon what they eat.

Pat Salloum, this was an easy question for me as I’m an avid fisherman and have read much on salmonid evolution. Pacific salmon and rainbow trout were named Salmo until around 1988

A trout is white meat and salmon are a pink meat.

I would have thought that the saltwater fish would have been different from the fresh water fish!?

One of the 62% that chose the (not so obvious) answer, trout!
