Sorry I didn't reply when you first posted.
To be honest March is when my pike fishing stops, they are usually spawning, followed by the water temperatures have risen enough to make catching pike very stressful for them, potentially resulting in fish that die after capture, especially so in the shallow waters of southern England. A lot of clubs only allow pike fishing from October to March.
Zander I think are more hardy in summer, and for summer fishing I would be out with lures, with gear heavy enough to bring any accidentally hooked pike in quickly so they don't suffer oxygen deprivation, the cause of stress.
