night sessions

i am looking to be doing some 24hr and some 48hr sessions over my local river this season after last season i think i really need some advice with only 3 bootlace eels max per session and lots of silvers in the day but i am aiming for the bream and tench or even a bigger eel also i done some piking sessions and no luck i think i am doing something wrong as i know this river( the river lark prickwillow stretch) is a very good piking river
any advice?
thanks

just like to point out i mean next season in the summer sorry

Dont know the river Dan but halibut pellet seems to work anywhere for the bream
