Got a load of fish, we're told (4)
I believe the answer is:
eyed
'got a load of' is the definition.
(to get a load of something is to look at or eye it)
'fish we're told' is the wordplay.
'fish' becomes 'ide' (type of fish).
'we're told' indicates a 'sounds like' (homophone) clue.
'ide' is a homophone of 'EYED'.
(Other definitions for eyed that I've seen before include "Vegetable" , "Watched with interest" , "Closely observed" , "Saw" , "Watched warily" .)
