Wound in a sea fish (6)
I believe the answer is:
reeled
'wound' is the definition.
(reeling is a kind of winding)
'in a sea fish' is the wordplay.
'in' means one lot of letters goes inside another.
'a sea' becomes 'red'.
'fish' becomes 'eel' (eel is a kind of fish**).
'red' going around 'eel' is 'REELED'.
(Other definitions for reeled that I've seen before include "Danced; staggered" , "Staggered in a dance perhaps" , "Staggered or tottered" , "swam around" , "Lurched" .)
