Recover on island seafood tours (7)
I believe the answer is:
reclaim
'recover' is the definition.
(synonyms)
'on island seafood tours' is the wordplay.
'on' becomes 're' (regarding).
'island' becomes 'i' (geographical abbreviation).
'seafood' becomes 'clam' (clam is a kind of seafood).
'tours' indicates putting letters inside (to tour can mean to go around).
'i' going within 'clam' is 'claim'.
're'+'claim'='RECLAIM'
(Other definitions for reclaim that I've seen before include "Salvage" , "Miracle (anag)" , "Make (land) available for use" , "Win back" , "Recover (materials/land) for subsequent use" .)
