On the contrary bullhead are "generaly" a night fish. In the 23 years of fishing them, about 25% of my successfull fishing had been during the day, especially this early in the season when the water is still cold. Granted, they are more active at night but I have filled buckets the day after a warm night rain. Leeches and sometimes stinky chicken livers are my prefered bait. Going out tonight for sure.
