Either term is correct but the better one (concept) is structure as it includes pond bottom contours. Actual spawning sites (beds) are not structure or cover conceptually. However, cover is used around beds to improve survival.

What to put around beds is dependent on survival in your pond. If to many yoy BG are surviving to reach your goal, then less cover around beds is better. If you want increased survival, then add cover to protect yoy.
