Caddisflies
The Tambre is a heritage salmon river flowing to the Noia ría, but salmon are now depleted and out of bounds. Its present practical value is as a granite spate river with brown trout in the steeper upper water and sea trout in the lower river and estuarine reaches. The 8-hour response time makes it attractive after rainfall, and the river still carries real migratory-fish atmosphere even though active salmon fishing should not be part of trip planning.
In Galicia's Atlantic trout rivers, resident browns feed through a spring build-up of olives and other up-wings into a long summer of caddis and small buzzers, with frequent spates and cool water keeping fish active; terrestrials from lush banks and meadows become important once levels settle and the banks green up.
