Avoid standard container with a tinned fish (8,4)

'tinned fish' is the definition.
(fish often found in tins)

'avoid standard container with a' is the wordplay.
I cannot quite understand how this works, but
'avoid' could be 'skip' (skip can mean to avoid or pass over) and 'skip' is found within the answer.
'standard' could be 'jack' (both can refer to a flag) and 'jack' is located in the answer.
'container' could be 'tun' (type of cask) and 'tun' is present in the answer.
'a' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
