St. Polycarp's Day

Today is the saint day for Polycarp, an early Christian martyr from Turkey. His name intrigues me. Is it Poly=many + carp = fish (which would make sense because this is the zodiacal month for Pisces) or is it + carp=complaints? I'm going with the fish idea, because of the "fishers of men" metaphor.
