Fish from dugout gone off (7)
I believe the answer is:
gudgeon
'fish' is the definition.
(gudgeon is a kind of fish)
'dugout gone off' is the wordplay.
I cannot quite see how this works, but
an anagram of 'gone' is 'geon' which is within the answer.
This explanation may well be incorrect...
'from' is the link.
(Other definitions for gudgeon that I've seen before include "Swimmer" , "Fish, or person easily cheated" , "Small carp-like fish" , "angler's bait" , "Small freshwater fish" .)
