"Rodney and I are heading to the mainland to catch a fish that seems to be just like a trout."
Carson Beckett[src]

This trout-like fish is a type of fish residing near Lantea's mainland and was similar to trout found on Earth. In 2007, Dr. Carson Beckett was thinking of going fishing on the mainland with Rodney McKay, but his plans ultimately fell through. (SGA: "Sunday") Due to the absence of Atlantis, this species (along with all other life on Lantea) will go extinct in approximately 15,000 years when the next coronal mass ejection hits the planet.
