Bones I found on fish (5)

I believe the answer is:

carpi

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

'i found on fish' is the wordplay.
'found on' means one lot of letters go next to another.
'fish' becomes 'carp' (carp is a kind of fish).
'i' after 'carp' is 'CARPI'.

(Another definition for carpi that I've seen is " Wrist bones - Capri (anag)".)

I've seen this clue in The Irish Times.
