Seafood in pub brawny lads demolished (6,3,6)

I believe the answer is:

dublin bay prawns

'seafood' is the definition.
(type of prawns)

'in pub brawny lads demolished' is the wordplay.
'demolished' is an anagram indicator.
'in'+'pub'+'brawny'+'lads'='inpubbrawnylads'
'inpubbrawnylads' anagrammed gives 'DUBLIN BAY PRAWNS'.

I've seen this clue in The Telegraph.
