Salmonidae

Marble trout

Salmo marmoratus · 40–70 cm; historically over 1 m, now extremely rare at that size.

By The Fly Desk

How it feeds

Marble trout are ambush predators that hold in deep pools against boulders and undercut banks, and they take fish, crayfish and large aquatic insects. Their marbled pattern is unique to the species and is the reason they were almost wiped out — hatcheries crossed them with brown trout for decades.

How to fish for it

Catch-and-release is compulsory wherever the species survives, and barbed hooks are banned. Fish a large streamer along the structure at first light, expect at most one take, and keep the fish in the water — a marble trout out of the net for a photograph is a fish the population cannot afford.
