Pond Boss Forums INTRO Questions & Observations Fish spawn

Well, my bass and bluegill have done their spring spawn. The bass are an inch to inch and half long. Bluegill are about an inch. My very disliked carp are full of eggs and ready to go. Do not know if the shad have spawn because i am still catching them with eggs and milt. The catfish have stoped biting so they have moved to the creek like each year before they spawn. I was wondering if alligator gar and drum can spawn if the water has no curent. I have these fish and never see any offspring from them.
