(5) The black bass builds its home in the rocks that lie along the bottom of the ocean wall; it is well protected from the fisherman, whose line will often snag and break before this fish is taken.

(7) The best way to catch the black bass is with a hook and sinker, whereas trolling is the best way to land a striped bass because this fish does not remain in one spot very long.
