    PER CURIAM:
    Four commercial boat captains were charged with violating
    the Lacey Act after they caught Atlantic striped bass in federal
    waters       and    later     sold    them.       The   Lacey        Act,     through        its
    incorporation of a federal regulation, criminalizes the taking
    and selling of Atlantic striped bass from federal waters. The
    Act,       however,       exempts     from        prosecution        fishing          that     is
    “regulated by a fishery management plan in effect” under the
    Magnuson-Stevens            Fishery     Conservation           and     Management            Act
    (“Magnuson-Stevens Act”).               
    16 U.S.C. § 3377
    (a).                     Citing that
    exception, the captains moved to dismiss the indictments.
    The    district        court    granted       the     motions        based      on    two
    premises.      It first found that a fishery management plan created
    by     the         Atlantic      States       Marine          Fisheries           Commission
    (“Commission”)         and    referenced      in     the      Atlantic       Striped         Bass
    Conservation        Act    (“Bass     Act”)   must      be    treated       as    a   plan     in
    effect under the Magnuson-Stevens Act. 1                     Next, the district court
    1
    The Government asserts error on that point, arguing that
    
    16 U.S.C. § 5158
    (c)—which catalyzed the district court’s
    reasoning—contains a scrivener’s error.       That is, Section
    5158(c)’s reference to “any plan issued under subsection (a)” is
    a textual anomaly, because subsection (a) in fact authorizes
    only regulations by the Secretary of Commerce, not plans.    The
    Government attributes this dissonance to a drafting oversight in
    1991 that left the “any plan” language in the statute while
    excising related verbiage.    Compare Pub. L. No. 100-589, 
    102 Stat. 2984
    , at § 6 (Nov. 3, 1988) with Pub. L. No. 102-130, 
    105 Stat. 626
    , at § 4(1)-(2) (Oct. 17, 1991).
    (Continued)
    4
    reasoned that the Commission’s plan regulated the boat captains’
    activity in federal waters.              Thus, the district court found that
    the exception applied.
    We conclude, however, that the text of the plan created by
    the Commission and referenced by the Bass Act in fact regulates
    only state coastal waters, and accordingly does not regulate
    fishing in federal waters. The only possible hook to federal
    waters in the Commission’s plan is the general statement that
    the Secretary of Commerce has authority to regulate bass fishing
    in federal waters. Even if this statement was enough to say that
    the   plan    regulated        federal     waters    (which    it   is   not),   the
    provision would be invalid, because the Commission—a collection
    of state representatives—has no authority to delegate power over
    federal waters to the Secretary of Commerce.
    Accordingly, we remand these cases to the district court
    with instructions to reinstate the indictments.
    I.   THE INDICTMENTS
    The    Appellees         Gaston    Saunders,    Bryan    Daniels,     Michael
    Potter,      and     Stephen     Daniels        (hereinafter    referred    to   as
    “Captains”)        are   the    captains    of    commercial    fishing    vessels.
    During 2009 and 2010, the captains each harvested several tons
    Because this appeal can be resolved without deciding
    whether 
    16 U.S.C. § 5158
    (c) contains a scrivener’s error, we do
    not reach the issue.
    5
    of bass from federal waters (known as the “exclusive economic
    zone,” or EEZ 2), which they subsequently transported and sold to
    commercial seafood dealers. 3
    Based on these actions, on January 15, 2015, the Government
    brought        separate     indictments       containing       multiple    Lacey     Act
    counts against each captain.                  The Government now appeals the
    district court’s dismissal of the indictments against Captains
    Potter and Stephen Daniel in full and against Captains Saunders
    and Bryan Daniels in part. 4            We consolidated the four cases.
    II.   THE REGULATORY FRAMEWORK
    A.     The Lacey Act
    The    Lacey     Act   makes    it       a   crime   to   take   wildlife    in
    violation       of   some    other    federal         law.    Specifically,     it   is
    illegal to, inter alia, transport, acquire, or sell any fish
    “taken possessed, transported, or sold in violation of any law,
    treaty, or regulation of the United States . . . .”                       
    16 U.S.C. § 3372
    (a)(1).          If one does so “by knowingly engaging in conduct
    2    On the eastern seaboard, the EEZ extends from three to
    200 miles offshore.     See 
    16 U.S.C. § 1802
    (11); 
    50 C.F.R. § 600.10
    ; 
    48 Fed. Reg. 10,605
    , 
    1983 WL 506851
     (Mar. 10, 1983).
    3     The indictment charged that these bounties involved
    bass with a market value greater than $350, as required by the
    Lacey Act. See 16 U.S.C. 3373(d)(1)(B).
    4    The indictments against Captains Saunders and Bryan
    Daniels also included counts for making false statements and
    aiding and abetting. Those counts are not before us.
    6
    that involves” the sale of such ill-gotten fish having a market
    value over $350, then he may be imprisoned, fined, or both.                                      
    Id.
    § 3373(d)(1)(B).
    Because the Bass Act, described below, forbids anyone from
    harvesting, retaining, possessing, or fishing for bass in the
    EEZ, the captains allegedly violated the Lacey Act when they
    caught several tons of bass in the EEZ during 2009 and 2010.
    B.        The Bass Act and the Commission
    Congress           has     found        that       Atlantic       striped        bass     are
    commercially,         economically,            and       recreationally      important.          
    16 U.S.C. § 5151
    (a)(1).            Due       to       their   migratory    nature,          “[n]o
    single    government            entity    has     full      management      authority”          over
    bass.     
    Id.
     § 5151(a)(2).                    Congress enacted the Bass Act “to
    support       and     encourage          the    development,         implementation,             and
    enforcement          of     effective          interstate          action     regarding          the
    conservation and management of the Atlantic striped bass.”                                      Id.
    §    5151(b).         To    accomplish          this       goal,   the     Bass    Act    divides
    regulatory          authority       over        Atlantic         striped     bass       into    two
    distinct, but interrelated, schemes: (1) federal waters and (2)
    state coastal waters.
    First, Congress outlined the regulation of bass in federal
    waters. 
    16 U.S.C. § 5158
    ; see 
    id.
     §§ 5152(6), 1802(11); supra
    footnote 2.          Section 5158(a) commands the Secretary of Commerce
    to    “promulgate           regulations          governing         fishing        for    Atlantic
    7
    striped bass in the exclusive economic zone . . . .”                                 The
    Secretary of Commerce must “consult” with, among others, the
    Commission      when    preparing    her       rules.        Id.   §   5158(b).       In
    addition to other standards, her regulations must be “compatible
    with the Plan and each Federal moratorium in effect on fishing
    for Atlantic striped bass within the coastal waters of a coastal
    State.”       Id. § 5158(a)(2) (emphasis added).
    A state coastal waters “plan” under the Bass Act is a plan
    (or amendment to such plan) for managing bass “that is prepared
    and adopted by the Commission.” 
    16 U.S.C. §§ 5152
    (5), 5152(10).
    The   Bass     Act   instructs    the    Commission       to    annually     determine
    whether       its    member-States      have    adopted        measures     for    their
    “coastal waters” (i.e., zero to three miles offshore) that fully
    implement and satisfactorily enforce the Commission’s plan.                          
    Id.
    § 5153(a); see id. § 5152(3).             The Commission then notifies both
    the     Secretary       of   Commerce          and      Secretary      of     Interior
    (“Secretaries”) of each such “negative determination.”                             Id. §
    5153(c); see id. § 5152(3).                At that point, the Secretaries
    jointly determine whether the particular State is, in fact, in
    compliance with the Commission’s plan.                   If not, the Secretaries
    “declare jointly a moratorium on fishing for Atlantic striped
    bass within the coastal waters of that coastal State,” violation
    of    which    is    punishable   civilly.       Id.    §§     5154(a),     (c).     The
    prospect of this federally-imposed moratorium therefore acts as
    8
    an enforcement mechanism against recalcitrant States that refuse
    to    abide    by   the    Commission’s           plan       governing       state    coastal
    waters. 5
    A    brief    comment       on     the     Commission’s          history       further
    illuminates the genesis and structure of the Bass Act.                                    States
    cannot enter into any agreement or compact without the consent
    of    Congress.      U.S.       Const.    art.     I,    §    10,     cl.    3.      In    1941,
    Congress      approved      the    interstate           compact       that    created        the
    Commission and endeavored to better manage fish populations on
    the Atlantic seaboard.            Pub. L. No. 77-539, 
    56 Stat. 267
     (May 4,
    1942); see also Pub. L. No. 81-721, 
    64 Stat. 467
     (Aug. 19, 1950)
    (approving addition of new States and repealing limitation on
    the    life   of    the    compact);        New    York       v.    Atl.     States       Marine

    appoints      members     to     the     Commission,          which    is     charged      with
    investigating       conservation         measures,       offering        suggestions        for
    coordination        of    the     States’       police       powers,        and   presenting

    Exercising these powers, the Commission in 1981 issued its
    first plan for Atlantic striped bass fishing in state coastal
    waters.     Atlantic States Marine Fisheries Commission, Fisheries
    Mgmt. Rep. No. 1: Interstate Fisheries Mgmt. Plan of the Striped
    Bass   (Oct.   1981)    (“1981    Plan”).        Faced        with    declining     bass
    populations,     the    1981     Plan    put     forth      several      “recommended
    management measures.”           
    Id.
     at 1-1 & 1-4.                But “attempts at
    implementing the plan failed due to [the Commission’s] lack of
    direct     regulatory     authority       over        the     individual       Atlantic
    states.”       Note,   Thomas    Rapone,       The    EEZ     Solution    to   Striper

    id. at 577
     (observing that as the product
    of “a mere interstate compact, the [Commission] still lacked the

    5.0 (Feb. 2003) (“Amendment 6”) (observing that “Commission does
    not have the authority to directly compel state/jurisdictional
    implementation of the measures” proposed).
    10
    Against    the   backdrop      of   this   collective   action   problem,
    Congress passed the Bass Act in 1984, Pub. L. No. 98-613, 
    98 Stat. 3187
     (Oct. 31, 1984), which functions as the cooperative
    federalism scheme explained above and summarized in the chart
    below.

    C.    The Lacey Act Exemption
    The Lacey Act exempts conduct from prosecution if it was
    “activity    regulated     by   a   fishery     management   plan   in   effect
    under” the Magnuson-Stevens Act.              
    16 U.S.C. § 3377
    (a) (emphasis
    added).     A Magnuson-Stevens Act plan is quite different from a
    11
    plan created by the Commission.              Magnuson-Stevens Act plans are
    created by one of eight regional councils (or occasionally the
    Secretary of Commerce) composed of various state and federal
    officials.     
    Id.
     §§ 1852(a)(1), (b)-(c), 1854(c).                  The regional
    councils themselves are creatures of the Magnuson-Stevens Act,
    id. § 1852(a)(1), not an interstate compact like the Commission.
    And   unlike   Commission      plans,    regional      councils’         plans   must
    include federally-mandated provisions and are subject to final
    approval by the Secretary of Commerce.             Id. §§ 1853(a), 1854(a).
    In any event, to resolve these appeals we need only decide
    whether the Commission’s plan (which the district court treated
    as a Magnuson-Stevens Act plan) regulates the captains’ activity
    of bass fishing in federal waters.               See supra footnote 1.              To
    that question we now turn.
    III.   DISCUSSION
    “We review a district court’s decision to grant a motion to
    dismiss an indictment de novo.”              United States v. Good, 
    326 F.3d 589
    , 591 (4th Cir. 2003).
    A.    The Commission’s plan
    The   district   court      concluded     that   the    Commission’s        plan
    authorizes the Secretary of Commerce to regulate striped bass in
    federal waters, the EEZ.          It further noted that the Secretary of
    Commerce     promulgated     a     regulation—
    50 C.F.R. § 697.7
    (b)—
    “prohibiting    fishing     for    Atlantic     striped      bass   in    the    EEZ,”
    12
    which is “the same regulation under which [defendants are] being
    prosecuted.” Thus, the district court held the Commission’s plan
    regulates      the   captains’    conduct    (by    way      of   the     Secretary      of
    Commerce’s rule that the plan “authorized”), and the Lacey Act
    exemption applies.       We disagree.
    1. The plan does not authorize the Secretary of Commerce’s
    regulation
    As an interpretive manner, the Commission’s plan does not
    authorize      the   Secretary    of   Commerce        to   issue       the    regulation
    banning fishing for bass in federal waters.
    The text of the Commission’s plan does not purport to grant
    any    power    to   regulate     federal    waters         to    the    Secretary       of
    Commerce.       In    fact,   a   portion    of    a    2003      amendment       to   the
    Commission’s plan reads:
    Management of striped bass in the EEZ is within the
    Jurisdiction of the Secretary of Commerce.      The
    responsibilities of the Secretary of Commerce are
    detailed in the Atlantic Striped Bass Conservation
    Act.
    Amendment 6, at p.38 § 4.8.8.1.                   This provision is a simple
    acknowledgement by the Commission of the Secretary of Commerce’s
    independent      authority    under    the   Bass      Act.       See     
    16 U.S.C. § 5158
    (a); 
    55 Fed. Reg. 40,181
    , 
    1990 WL 351745
     (Oct. 2, 1990); 
    50 C.F.R. § 697.1
    .         Moreover, Section 2.4 of Amendment 6 defines
    the    plan’s    “management      unit”      to    expressly        “exclud[e]         the
    Exclusive Economic Zone (3-200 nautical miles offshore).”                              
    Id.
    13
    at   v    &    20;    see   
    id.
        at    vii    &    39    §    4.9     (recognizing      that
    “management of striped bass in the exclusive economic zone (EEZ)
    is the responsibility of the Secretary [of Commerce],” while
    also     making      non-binding        recommendations          to     the   Secretary     of
    Commerce regarding federal waters as contemplated by 
    16 U.S.C. §§ 5158
    (a)(3),       (b)).       In    other      words,       the    Commission’s      plan
    disclaimed any regulatory role over federal waters and instead
    recognized       the    regulation       of    federal         waters    as   part   of    the
    powers granted to the Secretary of Commerce by the Bass Act.
    In sum, nothing in the Commission’s plan purports to grant
    authority over federal waters to the Secretary of Commerce.
    2. The plan cannot authorize the Secretary of Commerce’s
    regulation
    Even had the Commission tried to endow the Secretary of
    Commerce       with    some    form     of     power      over    federal     waters,      the
    attempt would have been legally meaningless.
    The   Secretary      of   Commerce         is    the    head    of   an   executive
    department of the United States and a member of the President’s
    cabinet. See 
    5 U.S.C. § 101
    ; U.S. Const. Art. II, § 2, cl.2.                               In
    other words, she derives her authority from federal sources—acts
    of Congress and the inherent Article II powers of the Executive
    Branch.        As it pertains to this case, her power to regulate
    federal waters comes directly from the Bass Act. 
    16 U.S.C. § 5158
    (a).
    14
    The   Commission,         by    contrast,        is    the    creature     of    an
    interstate compact that binds only the sovereign States that are
    parties to it.         See Pub. L. No. 77-539, 
    56 Stat. 267
     (May 4,
    1942); New York, 
    609 F.3d at 526
    .                  It is, for instance, “not a
    federal      agency    within         the   meaning      of    the”     Administrative
    Procedure Act, i.e., not an “authority of the Government of the
    United States.”        New York, 
    609 F.3d at 527
    .                   “The fact that the
    [Commission] was created by an interstate compact and approved
    by Congress does not alter th[e] analysis.” 
    Id. at 532
    ; see 
    id. at 533
     (“we cannot escape the fact that the entity itself is an
    aggregation of states”).
    Simply   put,    the      Commission,       as    a    compilation    of    State
    representatives,       is   charged         with   regulating        the   States’     own
    waters.      See 
    id. at 527
    ; Medeiros v. Vincent, 
    431 F.3d 25
    , 27
    (1st Cir. 2005).         The Secretary of Commerce regulates federal
    waters because that is what Congress told her to do in the Bass
    Act.    The Secretary of Commerce needs nothing further, and the
    Commission has nothing to bestow on her.
    B.    Void for Complexity
    As an alternative ground for affirming the district court,
    the captains ask us to find that the statutory scheme here is
    void for vagueness.         We disagree with the captains’ argument.
    A statute is unconstitutionally vague if it “(1) ‘fails to
    provide people of ordinary intelligence a reasonable opportunity
    15
    to understand what conduct it prohibits’ or (2) ‘authorizes or
    even       encourages      arbitrary       and        discriminatory        enforcement.’”
    United States v. Shrader, 
    675 F.3d 300
    , 310 (4th Cir. 2012)
    (quoting      Hill    v.    Colorado,      
    530 U.S. 703
    ,    732    (2000)).      The
    captains      present       only    the    first       theory.        In    assessing     the
    existence      of    fair       notice,    we    consider          “whether   a   statute’s
    prohibitions         are   set     out    in    terms       that    the    ordinary    person
    exercising ordinary common sense can sufficiently understand and
    comply with.”         
    Id.
     (internal quotation omitted).
    The captains’ vagueness argument contains an oddity and an
    irony.       The oddity is that vagueness challenges usually target a
    particular      word       or    phrase    as        critically      deficient. 6       Here,
    however, the captains launch a broadside attack on the entire
    “statutory       framework”         as    unconstitutionally              “convoluted     and
    confusing.”
    The irony is that this claimed convolution is mainly the
    product of the exceptionally novel (and ultimately unsupported)
    reading of the Lacey Act, Bass Act, and the Commission’s plan
    6  See, e.g., Johnson v. United States, -- U.S. --, 
    135 S. Ct. 2551
     (2015) (voiding “residual clause” in Armed Career
    Criminal Act); United States v. Shrader, 
    675 F.3d 300
    , 310-12
    (4th   Cir.   2012)  (evaluating   statutory  terms   “harass,”
    “intimidate,” and “course of conduct”); Martin v. Lloyd, 
    700 F.3d 132
    , 136 (4th Cir. 2012) (courts must place particular
    “phrases or words” in context when considering a vagueness
    challenge).
    16
    that the captains urged below.                The Government’s theory in the
    indictments    was    straightforward:           the   Lacey       Act    criminalizes
    taking wildlife in violation of a federal regulation; a federal
    regulation under the Bass Act makes it illegal to fish for bass
    in   federal   waters;       the   captains     fished       for   bass    in   federal
    waters; therefore, the captains committed Lacey Act crimes.
    To support their position, the captains tally the number of
    statutes, plans, and regulations they say must be consulted to
    divine   whether     their    conduct    was     illegal.          But   counting     the
    number of laws in a case is a poor way to decide a due process
    challenge:       Our     sister       circuits    have       squarely      held     that
    regulatory     complexity      does    not    render     a    statute     (or   set    of
    statutes) unconstitutionally vague.
    We recognize that putting together the pieces of this
    regulatory puzzle is not easy. To understand the crime
    with which Defendant was charged, one must look at
    four sources and read them together . . . . But a
    statute does not fail the vagueness test simply
    because it involves a complex regulatory scheme, or
    requires that several sources be read together, and
    Defendant has not directed us to a single case in
    which we have held otherwise.
    United States v. Zhi Yong Guo, 
    634 F.3d 1119
    , 1122 (9th Cir.
    2011); see United States v. Griffith, 
    85 F.3d 284
    , 288 (7th Cir.
    1996) (“The statutory structure involved is admittedly somewhat
    complicated—it takes three steps to get from state prostitution
    to federal money laundering. But complication is not tantamount
    to unconstitutional vagueness.               Here, each step in the statutory
    17
    analysis is well-defined.”) (emphasis in original).                      We think
    the principle of law in these cases is sound.                      Moreover, a
    “statute need not spell out every possible factual scenario with
    ‘celestial precision’ to avoid being struck down on vagueness
    grounds.” United States v. Whorley, 
    550 F.3d 326
    , 334 (4th Cir.
    2008).
    We hasten to add that the straightforward prohibition here—
    colloquially, “don’t fish for bass in federal waters”—has been
    on the books and readily comprehensible to those in the fishing
    industry (much less the general population) for over a quarter-
    century.

    1990 WL 351745

    Amend. 6 to the Interstate Fishery Mgmt. Plan, at p.5 § 2.3.3
    (Oct. 2014) (“Federal waters . . . ha[ve] been closed to the
    harvest, possession and targeting of striped bass since 1990”).
    Further,   “economic     regulation    is    subject     to    a   less    strict
    vagueness test because its subject matter is often more narrow,”
    and   because   market   participants       “can   be   expected    to    consult
    relevant legislation in advance of action.”                   Vill. of Hoffman

    , 309 (4th Cir.

    18
    The Lacey Act also contains a scienter requirement (two of
    them,    in    fact),   thus   forcing       the   Government   to    prove    the
    captains’ knowledge.
    Any person who violates [inter alia, 
    16 U.S.C. § 3372
    (a)]  by   knowingly  engaging  in   conduct  that
    involves the sale or purchase of, the offer of sale or
    purchase of, or the intent to sell or purchase, fish
    or wildlife or plants with a market value in excess of
    $350, knowing that the fish or wildlife or plants were
    taken, possessed, transported, or sold in violation
    of, or in a manner unlawful under, any underlying law,
    treaty or regulation, shall be fined not more than
    $20,000, or imprisoned for not more than five years,
    or both.
    
    16 U.S.C. § 3373
    (d)(1)(B).            A “scienter requirement alone tends
    to defeat” vagueness challenges to criminal statutes.                       United
    States v. Jaensch, 
    665 F.3d 83
    , 90 (4th Cir. 2011); see Gonzales
    v. Carhart, 
    550 U.S. 124
    , 149 (2007) (“scienter requirements
    alleviate vagueness concerns”); Colautti v. Franklin, 
    439 U.S. 379
    , 395 & n.13 (1979) (recognizing “that the constitutionality
    of a vague statutory standard is closely related to whether that
    standard incorporates a requirement of mens rea”); United States
    v. McLean, 
    715 F.3d 129
    , 137 (4th Cir. 2013); United States v.
    Shrader, 
    675 F.3d 300
    , 311 (4th Cir. 2012); see also United
    States    v.    Lee,

    ,       1394-95   (9th    Cir.     1991)
    (sustaining Lacey Act conviction against vagueness challenge due
    19
    to scienter requirement).     Consequently, we find no merit to the
    captains’ vagueness argument. 7
    *    *         *
    We conclude that the Lacey Act, 
    16 U.S.C. § 3377
    (a), does
    not except from prosecution the captains’ conduct alleged in the
    indictments.    We also reject the contention that the regulatory
    regime   governing   the   captains’    actions      is   unconstitutionally
    vague.   Accordingly, we reverse the orders of the district court
    dismissing     the   indictments       and       remand   the   cases   with
    instructions that the indictments be reinstated.
    REVERSED AND REMANDED
    7    The captains’ overbreadth argument (in truth, a single
    mention of the term) is insufficiently presented and thus
    waived. The same conclusion applies to their passing reference
    to the rule of lenity, which—like their vagueness challenge—does
    not direct us to any particular statutory words or phrases that
    we should interpret leniently.
