Delivers fish, something avoided during social distancing? (9)

Ross

I believe the answer is:

handshake

I'm a little stuck... Click here to teach me more about this clue!

'something avoided during social distancing?' is the definition.
I can't tell whether this definition defines the answer.

'delivers fish' is the wordplay.
'delivers' becomes 'hands' (I am not sure about this - if you are sure you should believe this answer much more).
'fish' becomes 'hake' (type of fish).
'hands'+'hake'='HANDSHAKE'

Can you help me to learn more?

(Other definitions for handshake that I've seen before include "A link" , "Conventional sort of manual greeting" , "Gesture of greeting or of agreeing a deal" , "acknowledgment" , "Physical greeting" .)

I've seen this clue in The Telegraph.
