(b) Conservation rangers and other authorized personnel of the department are authorized to take samples from, to enter and have access to, and to examine during normal working hours and at any time when the licensed or authorized activity is being conducted all shellfish beds, places of business, and other places where shellfish are grown, kept, stored, sold, or held in possession with intent to distribute, sell, or give away. Such personnel are also authorized at any time to take such samples of shellfish as are necessary to carry out the purposes of this article and to have access to and take samples from all streams, tributaries thereof, and lands adjacent thereto, the waters draining from which may come into contact with shellfish.
