Fish in shop, a halibut (4)

Ross

I believe the answer is:

opah

'fish' is the definition.
(opah is a kind of fish)

'in shop a halibut' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OPAH' can be found hidden inside 'shop a halibut'.

(Other definitions for opah that I've seen before include "Kingfish" , "Ocean swimmer" , "Large deep-sea fish" .)

I've seen this clue in The Hindu.
