About 30 species within the arctic regions belonging to the families Petromyzontidae, Acipenseridae, Anguillidae, Clupeidae, Osmeridae, Salmonidae, and Gasterosteidae exhibit diadromous behavior (i.e., spend part of their lives in the marine environment and migrate to freshwater to spawn, or the converse).

DISTRIBUTIONThe trout in the Río del Presidio drainage, just north of 24° N latitude the Tropic of Cancer, reflect the southernmost natural distribution of any species of the family Salmonidae, but questions have been raised concerning the genealogy of these trout.

The family Salmonidae represents an array of evolutionarily primitive fishes whose roots extend back into the Cretaceous period, perhaps about 100 million years ago.

They are by far the largest species of char and the third-largest species of the family Salmonidae—a 102-pound 46.3-kg lake trout was caught in 1961.

The family Salmonidae includes trout, salmon, char, whitefishes, ciscoes, inconnu, and graylings in North America and several more genera from Europe and Asia.

When rainbow trout and cutthroat trout were still classified in the genus Salmo, a key to the identification of genera and species in the family Salmonidae would illustrate a characteristic, such as the number of rays in the anal fin, and state “more than 12 anal fin rays (typically 14-18) versus 12 or fewer (typically 9-11)” to distinguish, respectively, Oncorhynchus and Salmo.

We can speculate that the beginning of the family Salmonidae was associated with a doubling of the chromosome number of an early ancestor.

We know that trout-like fishes of the family Salmonidae were swimming in the cool and cold freshwater habitats of the Earth when dinosaurs dominated the planet.
