IIRC Lusk makes a differentiation between "structure" and "habitat."

"Habitat" is the physical entities that fish need to live - spawning beds, places to hide when little, etc. "Structure" is physical entities which concentrate fish in certain locations, but which do not promote greater fish biomass overall - underwater forms, canyons, and rockpiles below the light penetration zone come to mind.

Using these definitions, adding "structure" cannot increase the carrying capacity of the pond; adding "habitat" may do so (if basic needs were lacking ahead of time) or may be used to tailor fish populations toward the manager's goals (adding SMB spawning beds if you desire a breeding population of bronzebacks).

BTW, nice job Bruce, totus populus diligo RAY.
