Welcome to the bull. If I was planning on fishing at night with live shrimp, this is what I would do. Put a small kahle hook 18" to 24" under a popping cork with 15lb to 20lb floro or mono leader. Find some lights shinning in the water from piers or bridges and fish them. Try not to get too close and fish the edges of the light along with in the middle of where the light is shinning. Sometimes I like to cast into the light and let it drift into the shadow.
