"Speckled" fish (5)
I believe the answer is:
trout
'speckled fish' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for trout that I've seen before include "Fish (associated with Schubert?)" , "Tasty fish, perhaps of rainbow kind" , "Catch" , "Game fish related to salmon" , "Schubert work; fish" .)
