Reported location of fish (6)
I believe the answer is:
plaice
'fish' is the definition.
(I know that plaice is a type of fish)
'reported location' is the wordplay.
'reported' shows a homophone (sound like).
'location' becomes 'place' (a location is a place).
'place' sounds like 'PLAICE'.
'of' acts as a link.
(Other definitions for plaice that I've seen before include "Location of the fish" , "Flatfish; sounds like put" , "Tasty flatfish I place here" , "The fish sounds as if it hits the spot" , "A fish; sounds like put" .)
