Fish and one type of meat served up repeatedly (4-4)

I believe the answer is:

mahi mahi

'fish' is the definition.
(I've seen this before)

'one type of meat served up repeatedly' is the wordplay.
'one' becomes 'i' (Roman numeral).
'type of meat' becomes 'ham'.
'served up' shows that the letters should be reversed in order (in a down clue, letters go up).
'repeatedly' says to double the letters.
'i'+'ham'='iham'
'iham' written backwards gives 'mahi'.
'mahi' doubled is 'MAHI-MAHI'.

'and' is the link.

(Another definition for mahi mahi that I've seen is " fish".)

I've seen this clue in The Telegraph.
