Angler’s name for a perch? (3)
I believe the answer is:
rod
'perch?' is the definition.
('rod' can be a synonym of 'perch')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rod that I've seen before include "Old saying 'Spare the . . . and spoil the child'" , "Stick; angler" , "Baton, pole" , "Cane used for flogging" , "that most anglers use" .)
