Having caught the fish, skedaddled (6,2)

Ross

I believe the answer is:

hooked it

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

'fish skedaddled' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'having caught the' is the wordplay.
I cannot really see how this works, but
'caught' could be 'hooked' (hooking is a kind of catching) and 'hooked' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
A single letter 'i' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

(Another definition for hooked it that I've seen is " Ran off".)
