Hi Frank I do a bit of squid fishing land based off the rocks & have noticed that they seem to bite better during the day on the lead up to and around the new moon, whereas around the full moon period at dusk & into the night & in both situations on a rising tide low up or the last few hours before the top of the tide, around the full moon like you I get the odd one here and there after a lot of casts during the day, could be to do with getting a good feed on the lit nights, I don’t profess to be an expert as I still occasionally get donuts, I hope this helps & happy fishing
