George avoids seafood (8)

I believe the answer is:

geoducks

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

'seafood' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'george avoids' is the wordplay.
'george' becomes 'geo'.
'avoids' becomes 'ducks' (duck can mean to avoid).
'geo'+'ducks'='GEODUCKS'

Can you help me to learn more?

I've seen this clue in The Times.
