'fish finally gutted' is the definition.
I can't tell whether this definition defines the answer.

'and put in a corner' is the wordplay.
'and' becomes 'n' (common abbreviation for 'and').
'put in' is an insertion indicator.
'corner' becomes 'gled' (I can't explain this - if you can you should give a lot more credence to this answer).
'a'+'gled'='agled'
'n' inserted inside 'agled' is 'ANGLED'.

Can you help me to learn more?

(Other definitions for angled that I've seen before include "Glenda (anag.)" , "Slanted" , "Crooked; biased" , "Fished with rod and line" , "Cornered" .)
