'a fish' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'heard character register' is the wordplay.
'heard' indicates a 'sounds like' (homophone) clue.
'character' becomes 'c'.
'register' becomes 'bass' (vocal register).
'c' is a homophone of 'sea'.
'sea'+'bass'='SEABASS'
