Pale Yellow Emerger

Asturian pale emerger

TroutFilm

A delicate pale yellow CDC or dubbed emerger for Asturian and Cantabrian rivers — tied to match the pale, cream-yellow emerging duns that hatch in spring and early summer on the calcareous rivers of northern Spain. Fish will take it and refuse everything else when the hatch is on.

Fish this when

Spring and early summer on Asturian limestone rivers during pale olive or pale watery hatches. In slower glides where emerging nymphs pause in the film.

Why it works

Pale yellow matches the colouration of emerging Baetis and Ephemerella duns on Cantabrian limestone rivers. A fly that sits in the film rather than on it matches the exact moment of emergence that selective trout focus on.
