How To Prune Boysenberry Vines?

Question

How do I prune boysenberry vines after the first year? Do you remove suckering stems? My berries are thornless variety and were prolific producers the first year but I must have pruned them incorrectly for the second year since they are not producing much but are producing a ton of suckering stems.
