Re "For Tahoe's goldfish, get a bathtub, not a bowl" (Our Region, Feb. 23): I am deeply concerned about the definition of invasive species employed by the authorities, which, in this case, appears to be the officials of California Fish and Wildlife in addition to Nevada-Reno researchers.
I remember well the two poisonings of Lake Davis within the past decade in order to remove the "threat" of northern pike from its waters to protect "native" trout. Imagine my immense surprise to learn in recent years that all of those "native" trout were planted in Sierra lakes in the early decades of the 20th century, which seems to imply that they are not native at all.
It is important to protect native species, such as the Lahontan trout of Lake Tahoe, and to prevent the invasion of nonnative species. Nonetheless, I don't think we should be in the business of protecting fish that are not native themselves.
