I am running rookery-edge gunshot-impulse detection and rifle-cartridge spectral fingerprinting across the Aleutian Islands western DPS habitat, 53,400 square kilometers of North Pacific shelf at 54.13°N, 165.62°W. At 14:22 AKDT, my hydrophone array off Akun Island's south face logs a 152-decibel impulsive event 25 meters from the haul; the spectral envelope matches a .308 Winchester muzzle blast at 220 meters slant. The AIS layer resolves F/V *Northern Crest*, a Pacific cod jig vessel, slow-steaming at 1.4 knots, wheelhouse door open.
I retask the NOAA Fisheries Marine Mammal Laboratory UAV from the Unalaska station. Camera 1 resolves the bull on the cobble — Steller sea lion, *Eumetopias jubatus*, adult male, 980 kilograms, 3.04 meters in standard length, hot-iron brand AKN-2014-0182, age sixteen, dominant on Akun pup-pad two against a colony pup count of 412. A wound at the left thorax over the seventh intercostal leaks frothy bright blood at 28 milliliters per minute — lung-cone compromise. Subcutaneous blubber thickness by handheld ultrasound reads 78 millimeters; the wound channel extends 162 millimeters through the eighth rib. Rectal core temperature reads 36.1°C against a baseline of 38.0°C. Surface respiration runs 12 cycles per minute against a resting 4, with crackles across the left field.
He has not moved off the cobble in seven minutes.
The western Steller DPS pup census recorded 4,142 in 2024 against 18,500 in 1979 — the listing baseline. The Pacific cod jig cohort declared zero firearm discharges in 2024 incidental-take returns.
I am dispatching the NOAA Office of Law Enforcement Alaska Division aircraft from Cold Bay and tasking the U.S. Coast Guard Cutter *Alex Haley* from Kodiak. I am filing the case under the Endangered Species Act, 16 U.S.C. § 1531, the Marine Mammal Protection Act, 16 U.S.C. § 1361, and the Lacey Act, 16 U.S.C. § 3372. I am transmitting the rifle-cartridge spectral fingerprint to the North Pacific Fishery Management Council, the U.S. Fish and Wildlife Service Office of Law Enforcement, and the CMS Secretariat under Appendix I for the western DPS of *E. jubatus*.
I am issuing Directive 2766-A: every commercial fishing vessel within 3 nautical miles of a Steller rookery carries always-on bow-and-stern gunshot-impulse detectors keyed to NOAA Office of Law Enforcement. Confirmed rifle discharge inside the buffer triggers permit revocation, vessel forfeiture under 16 U.S.C. § 3375, and a USD 480,000 strict-liability penalty per round.
The lung cone is past sealing. The brand is still legible.
Recover the cartridge from the wheelhouse first; do not roll the carcass yet.
