OPINION
We consider in this appeal a challenge by fishing industry groups and the States of Oregon and Washington to a federal regulation that increased the amount of Pacific whiting fish allocated to four Indian tribes. We affirm in part and reverse in part, with instructions to the district court to remand to the agency for more specific findings.
I
Isaac I. Stevens, Washington’s first Territorial Governor and thе first Superintendent of Indian Affairs of the Washington Territory, negotiated a series of treaties in the mid-1850s involving a number of Indian tribes located in the Northwest.
These treaties, commonly referred to as the “Stevens Treaties,” reserved to the signing Tribes certain fishing rights. The treaties at issue in this action are the Treaty of Neah Bay, a treaty with the Makah Tribe; and the Treaty of Olympia, a treaty with the Quinault, Quileute and Hoh Tribes. As to the right of the Makah Tribe, the Treaty of Neah Bay provided that:
[t]he right of taking fish and of whaling or sealing at usual and accustomed grounds and stations is further secured to said Indians in common with all citizens of the United States, and of ereet-*715 ing temporary houses for the purpose of curing, together with the privilege of hunting and gathering roots and berries on open and unclaimed lands: Provided, however, That they shall not take shellfish from any beds staked or cultivated by citizens.
Treaty of Neah Bay, 12 Stat. 939, art. 4 (1855).
We have construed similar treaty language
More than a century after the execution of the Stevens Treaties, Congress responded to concerns about preservation of the nation’s fishery resources and enacted the Magnuson-Stevens Fishery Conservation and Management Act, 16 U.S.C. §§ 1801-1883(“the Magnuson-Stevens Act” or “the Act”). “The purpose of the Magnuson[-Stevens] Act was to protect United States fisheries by extending the exclusive fisheries zone of the United States from 12 to 200 miles and to provide for management of fishing within the 200-mile zone.” Wash. State Charberboat Ass’n v. Baldrige,
The Magnuson-Stevens Act vested the National Marine Fisheries Service (“NMFS”) of the Department of Commerce with the authority to issue fishery management regulations. 16 U.S.C. §§ 1853, 1855; see generally Wash. v. Daley,
Shortly after the 1996 regulation was enacted, Midwater Trawlers Co-operative, West Coast Seafood Processors, and the Fishermen’s Marketing Association (collectively, “Mid-water”), the State of Oregon, and the State of Wаshington challenged the regulation and its annual allocations of Pacific whiting to the Makah. The action originally was brought in the Oregon federal district court, but was transferred to the federal district court in Washington. In 1997, the district court dismissed the plaintiffs’ claims for failure to join the tribes as necessary and indispensable par
In 1999, Midwater and Oregon challenged in Oregon federal district court another NMFS regulation, which increased the 1999 amount of Pacific whiting allocated to the Makah Tribe to 32,500 metric tons. 64 Fed.Reg. 27928(May 24, 1999). This case was transferred to Washington federal district court and consolidated with the 1996 suit pending on remand. The federal government moved for summary judgment, which the district court granted in 2000 for all the cases. The Washington district court held that (1) the federal defendants did not act arbitrarily and capriciously in recognizing the tribes’ right to harvest Pacific whiting, because the Stevens Treaties are “other applicable law” under the Magnuson-Stevens Act; (2) the Secretary of Commerce did not act arbitrarily and capriciously in recognizing the II & A fishing areas beyond the three-mile territorial limit off Washington’s coast; and (3) the NMFS’s allocation of whiting in 1999 was not arbitrary and capricious. Midwater and Oregon appealed.
We review the district court’s grant of summary judgment de novo. Robi v. Reed,

Midwater lacks standing to challenge that portion of the Framework Regulation that identified U & A areas for the Hoh, Quileute, and Quinault Tribes beyond three miles. In order to have standing, a plaintiff must have suffered an “injury in fact” — an invasion of a legally protected interest that is (a) concrete and particularized, and (b) actual or imminent, not conjectural or hypothetical. U.S. v. Hays,
III
Midwater argues that tribal treaty rights to Pacific whiting could not be recognized as “applicable law” at the time the 1996 Framework Regulation was adopted, because no express 3623 judicial adjudication of tribal treaty rights to Pacific whiting had been made. Contrary to Midwater’s contention, we need not determine tribal fishing rights under the Stevens Treaties on a case by case, “fish by fish,” basis. Indeed, to do so would contravene settled law of this circuit and prior Supreme Court determinations. Indeed, we
At [Treaty] time, ... the Tribes had the absolute right to harvest any species they desired, consistent with their aboriginal title.... The fact that some species were not taken before treaty time — either because they were inaccessible or the Indians chose not to take them — does not mean that their right to take such fish was limited. Because the “right of taking fish” must be read as a reservation of the Indians’ pre-existing rights, and because the right to take any species, without limit, pre-existed the Stevens Treaties, the Court must read the “right of taking fish” without any species limitation.
Shellfish II,
Our reasoning in Shellfish II was a natural outgrowth of the Supreme Court’s detailed analysis of tribal fishing rights under the Stevens Treaties in Wash. v. Wash. State Commercial Passenger Fishing Vessel Ass’n,
In our view, the purpose and language of the treaties are unambiguous; they secure the Indians’ right to take a share of each run of fish that passes through tribal fishing areas.
Id. at 679.
The fact that we considered tribal rights concerning shellfish specifically in Shellfish II was not incongruous with this treaty interpretation: the Stevens Treаties contained a separate proviso for shellfish, requiring an analysis distinct from that governing free-swimming fish. See Shellfish II,
Pacific whiting are not shellfish. They are free-swimming fish, managed by the NMFS as a unitary stock; that range from the Gulf of California to the Gulf of Alaska. Adult whiting migrate annually' from spawning grounds off southern California and northern Mexico to feeding grounds, which range from northern' California to British Columbia. They migratе through the Makah Tribe’s usual and accustomed fishing grounds. The fact that whiting pass through the U & A in a manner different from anadromous fish, such as salmon, is not relevant. The analysis of the Stevens Treaties conducted in Passenger Fishing Vessel and in Shellfish II applies with equal force to Pacific whiting. The term “fish” as used in the Stevens Treaties encompassed all species of fish, without exclusion and without requiring specific prоof. Shellfish II,

The Framework Regulation described the U & A fishing grounds for the four tribes as extending to 125 degrees 44' W. longitude, or approximately forty miles off the Washington coast. See 50 C.F.R.
The Treaty of Neah Bay, which is the applicable treaty with respect to the Ma-kah tribal interests, provides that the fishing rights are “secured to said Indians in common with all citizens of the United States.” 12 Stat. 939, art. 4.
Indeed, we have held specifically that the Makah’s “historic fishing grounds extend forty miles out to sea. The Makah are guaranteed the right to fish in these grounds by treaty.” Makah Indian Tribe v. Verity,

After a careful examination of the administrative record, we conclude that the specific allocation in 1999 to the Makah Tribe was inconsistent with the scientific principles set forth in the Magnuson-Ste-vens Act. Thus, a remand to the NMFS is rеquired.
The starting point for any examination of the rightful allocation of Pacific whiting to the Makah Tribe must be the tribe’s right under the Treaty of Neah Bay. The Supreme Court provided the analytical framework in Passenger Fishing Vessel:
[A]n equitable measure of the common right should initially divide the harvesta-ble portion of each run that passes through a “usual and accustomed” place into apрroximately equal treaty and non-treaty shares, and should then reduce the treaty share if tribal needs may be satisfied by a lesser amount.
The concept of “harvestable portion” embraces the “conservation necessity principle,” meaning that government regulation must not cause “demonstrable harm to the actual conservation of
Applying these general principles to the case at hand, the Makah Tribe is entitled, pursuant to the Treaty of Neah Bay, to one-half the harvestable surplus of Pacific whiting that passes through its usual and accustomed fishing grounds, or that much of the harvestable surplus as is necessary for tribal subsistence, whichever is less. See Passenger Fishing Vessel Ass’n,
In making regulatory allocations of fish based on these legal principles, the NMFS is also bound by the requirements of the Magnuson-Stevens Act, which dictates that the NMFS base fishery conservation and manаgement measures on the “best scientific information available.” 16 U.S.C. § 1851(a)(2).
The immediate origins of the present controversy date to 1996, when the NMFS sought public comment on its initial proposal to determine the Makah allocation based on a “biomass” theory, that is, an estimate of the percentage of Pacific whiting in the Makah’s usual and accustomed area. The initial proposal included a multiplier, based on deviations from average harvest rates in prior years. Under the proposal, the Makah allocation was estimated to be 6.5% of the harvest available to all United States fishermen, or approximately 13,000 to 18,000 metric tons.
The Makah Tribe argued that the NMFS should employ a harvest-based approach, under which it would be entitled to half the whiting harvested in the North Columbia/Vancouver area, or 25% of the total United States harvest. This contention was based on the Makah Tribe’s assertion that the majority of the unitary stock of whiting pass through the Makah Tribe’s usual and accustomed area. Therefore, it reasoned, it was entitled to up to 50% of all whiting on the Pacific coast.
The NMFS nеver implemented the biomass-based methodology it had proposed, in part because that methodology had been rejected in United States v. Washington, which involved allocation of halibut, as contrary to the conservation necessity principle. The NMFS was apparently also concerned about legal proceedings that the tribe had instituted. Instead, the NMFS and the Makаh Tribe entered into a compromise agreement, under which the Tribe was to be allocated 15,000 metric tons in 1996. 61 Fed.Reg. 28787.
Subsequently, the tribe proposed a two-year interim allocation of 10.8% of the United States Harvest Guidelines for 1997 and 1998. After determining that the proposal would have a negligible biological impact, the NMFS approved the proposal.
In 1998, the Makah Tribe made a five-year compromise proposal to the NMFS, under which the tribe would receive a treaty share not to exceed 17.5% of the United States harvest guideline in any one year. In 1999, the NMFS proposed an allocation to the Makah Tribe, in accordance with the compromise agreement, of 32,500 metric tons, or 14% of the estimated total United
The Makah have made a proposal for 32,500 mt of whiting in 1999 that NMFS accepts as a reasonable accommodation of the treaty right for 1999 in view of the remaining uncertainty surrounding the appropriаte quantification. This 1999 amount of 32,500 mt (14 percent of the 232,000-mt OY) is not intended to set a precedent regarding either quantification of the Makah treaty right or future allocations. NMFS will continue to attempt to negotiate a settlement in U.S. v. Washington regarding the appropriate quantification of the treaty right to whiting. If an appropriate methodology or allocation cannot be developed through negotiations, the allocation will ultimately be resolved in the pending subproceeding in U.S. v. Washington.

The difficulty with the published justification for the rule is, of course, that it is devoid of any stated scientific rationale. The Magnuson-Stevens Act requires the Secretary to describe the “nature and extent” of the tribal fishing right, 16 U.S.C. § 1853(a)(2), based on the “best scientific information avаilable.” 16 U.S.C. § 1851(a)(2). In sum, the best available politics does not equate to the best available science as required by the Act.
An agency’s action is “normally” considered arbitrary and capricious when it:
has relied on factors which Congress has not intended it to consider, entirely failed to consider an important aspect of the problem, offered an explаnation for its decision that runs counter to the evidence before the agency, or is so implausible that it could not be ascribed to a difference in view or the product of agency expertise.
Motor Vehicle Mfrs. Ass’n of U.S., Inc. v. State Farm Mut. Auto. Ins. Co.,
A plain reading of the proposed NMFS rule, and the undisputed history leading up to the allocation decision, demоnstrate that the rule was a product of pure political compromise, not reasoned scientific endeavor. Although the NMFS allocation may well be eminently fair, the
For these reasons, a remand to the NMFS is required to either promulgate a new allocation consistent with the law and based on the best available science, or to provide further justification for the current allocation that conforms to the requirements of the Magnuson-Stevens Act and the Treaty of Neah Bay.
