Save seafood caught for husband instead (6)
I believe the answer is:
scrimp
'save' is the definition.
(scrimping is a kind of saving)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for scrimp that I've seen before include "Be prudent" , "Skimp, stint" , "make economies" , "Do or spend less than is needed" , "Use or do less than is needed, be mean" .)
