That’s for the Coast Guard. NOAA has the authority to board and inspect vessels under the Magnuson-Stevens Act which is the main fisheries management law in the US. If you want the citation it is found at 16 U.S.C. 1857. The relevant authority for NOAA to board and inspect vessels reads:
It is prohibited to...
(D) to refuse to permit any officer authorized to enforce the provisions of this Act (as provided for in section 311) to board a fishing vessel[/COLOR] subject to such person's control for the purposes of conducting any search or inspection in connection with the enforcement of this Act or any regulation, permit, or agreement referred to in subparagraph (A) or (C);
(E) to forcibly assault, resist, oppose, impede, intimidate, or interfere with any such authorized officer in the conduct of any search or inspection described in subparagraph (D);
(F) to resist a lawful arrest for any act prohibited by this section;
(G) to ship, transport, offer for sale, sell, purchase, import, export, or have custody, control, or possession of, any fish taken or retained in violation of this Act or any regulation, permit, or agreement referred to in subparagraph (A) or (C);
(H) to interfere with, delay, or prevent, by any means, the apprehension or arrest of another person, knowing that such other person has committed any act prohibited by this section;
