DECISION & ORDER Unkechaug Indian Nation (the “Nation”) and Harry B. Wallace (collectively, “Plaintiffs”) bring this action pursuant to 25 U.S.C. §2201 and Fed. R. Civ. P. 65 seeking a permanent injunction and declaratory judgment against the New York State Department of Environmental Conservation (“NYSDEC”) and Basil Seggos, the NYSDEC Commissioner (collectively, “Defendants”). In the Complaint filed on February 21, 2018, Plaintiffs allege NYSDEC’s regulations unlawfully interfere with Plaintiffs’ fishing rights in designated Reservation areas and in customary fishing waters. ECF No. 1. Specifically, Plaintiffs argue their fishing rights are protected by treaty and enforceable against NYSDEC, NYSDEC’s regulations are preempted by federal law, and NYSDEC’s regulations interfere with tribal self-government and impair Plaintiffs’ freedom of religious expression. On October 1, 2021, Defendants and Plaintiffs filed fully-briefed cross-motions for summary judgment pursuant to Fed. R. Civ. P. 56. ECF Nos. 98, 104. For the reasons stated below, Defendants’ Motion for Summary Judgment at ECF No. 98 is GRANTED and Plaintiffs’ Motion for Summary Judgment at ECF No. 104 is DENIED. BACKGROUND The Unkechaug Indian Nation (the “Nation”) is recognized under both federal and New York state law. See Compl. 2 (citing Gristede’s Foods, Inc. v. Unkechuage Nation, 660 F. Supp. 2d 442, 469-70 (E.D.N.Y. 2009) (Matsumoto, J.)); N.Y. Indian Law §2. On February 21, 2018, the Nation and its chief, Harry B. Wallace (“Chief Wallace”), (collectively, “Plaintiffs”) filed a Complaint against the New York State Department of Environmental Conservation (“NYSDEC”) and Basil Seggos, the NYSDEC Commissioner (collectively, “Defendants”). See Compl. 1, ECF No. 1. Plaintiffs bring this action pursuant to 25 U.S.C. §2201 and Fed. R. Civ. P. 65, seeking a judgment from this Court that they are not subject to Defendant NYSDEC’s regulations and enforcement authority over fishing in reservation lands and Unkechaug customary fishing waters. Id. Specifically, Plaintiffs challenge Defendants’ attempts to regulate, restrict, and criminally prosecute Plaintiffs for fishing in their reservation and customary fishing waters and allege their claims accord with inherent native sovereignty, religious freedom and expression, treaties, and other federal laws. Id. At the heart of this case is New York State’s effort to conserve the American eel (Anguilla rostrata) species. The American eel represents an important resource for both biodiversity and human use. Kerns Dec., ECF No. 101, Ex. 5 at 17. This species possesses significant ecological, cultural, and commercial value and has therefore been the subject of increasingly stringent protection at the federal and state level. The Atlantic States Marine Fisheries Commission (“ASMFC” or “the Commission”), a congressionally authorized interstate regulatory body comprised of scientists and marine policy experts, controls much of the species’ oversight protection. See Kerns Dec., Ex. 4 (Atlantic States Marine Fisheries Commission, Interstate Fisheries Management Program Charter).1 The Commission has tracked trends in the American eel’s population over the past few decades. According to ASMFC studies, the American eel population has been steadily declining since the 1990s.2 In an attempt to preserve the species’ population, the Commission has implemented various regulatory measures. See Kerns Dec., Ex. 4 at 16. The Commission, together with the fifteen Member States which comprise the organization, carry out this mandate by generating Fishery Management Plans (“FMPs”). 16 U.S.C. §5104(a) (prescribing state implementation of coastal fishery management plans; detailing coastal fishery management plans). The Commission first adopted an FMP pertaining to American eels in the 1990s. See Def’s Mot. for Summary Judgment (“Def’s Mem.”), ECF No. 99 at 20. The FMP statutorily required ASMFC Member States — including New York — to impose fishing regulations with respect to the American eel in an attempt to conserve the species. See 16 U.S.C. §5104(b) (setting forth state implementation and enforcement obligations) (“Each State identified under [16 U.S.C. §5104(a)] with respect to a coastal fishery management plan shall implement and enforce the measures of such plan within the timeframe established in the plan.”). Despite the efforts of the Commissions and its Member States, ASMFC reports compiled in 2012 and 2017 confirmed the species’ population continued to decline. Id.; see also Kerns Dec., Ex. I at 14-33 (2017 ASMFC American Eel Stock Assessment Update stating the American eel’s population is in a “depleted state”). Indeed, the rate of the American eel’s population decline has worsened in recent years due to the emergence of a lucrative overseas trade in the species, which has further spurred overfishing. Id. at 10; see also Def’s Mem. at 17. In an effort to combat this precipitous population decline, the ASMFC adopted Addenda III (2013) and IV (2014) to the FMP. See Kerns Dec., Ex. G; H. These new regulations impose greater fishing limitations on American eels, including stricter size and catch restrictions. Id. As an ASMFC Member State, New York is required to adopt and enforce the FMP and the supplemental Addenda thereto pursuant to 16 U.S.C. §5104. See also Kreshik Dec., ECF No. 102 5. Accordingly, the State promulgated N.Y.C.R.R. §§10.1 (a) and (b) and 40.1(f) and (i), making it illegal to take or possess American eels less than nine inches long, which includes all juvenile eels, also known as “glass eels.” Id.; see also Kerns Dec. 35. The State’s attempt to regulate fishing, including its ban on taking glass eels in nonreservation customary fishing waters, is at the core of Plaintiffs’ case. Plaintiffs claim fishing and whaling have been the Nation’s “main economic engine” for “time immemorial.” Compl.
