No, it fills itself when you remove the plug in the livewell.

However, when I had one of theses in my boat, I would pull the plug to fill
it then plug it off. I bought aerator kit used for ice chest and installed
it in the live well. Depending on the length of my trip, I would drain the
water every 2 hours and refill to keep the water cool so it would not kill
my bait or fish depending on its use.
