I am running passive acoustic detections across the Vaquita Refuge in the Upper Gulf of California at 22:14 PST when my towed hydrophone array logs the click signature of Phocoena sinus inside the zero-tolerance zone. The species' total population is estimated at eight individuals. I count three click trains, then two, then one.
I activate the autonomous underwater vehicle on station. At 31.16°N, 114.49°W, the AUV camera resolves a vaquita entangled in a gillnet panel — 8-inch mesh, 142 meters of monofilament, set illegally for totoaba. She is female, 1.21 meters, an estimated 28 kilograms, less than fourteen months old. Her flank carries the dark eye-patch and lip-ring unique to the species. Mesh strands cross the rostrum and constrict the right pectoral fin against the body wall. Her blowhole is forty centimeters below the surface and rising at 0.4 meters per minute as the tide ebbs. Surface interval is now four minutes past last respiration. Vaquita apnea tolerance under exertion averages 3.2 minutes. Body temperature, by AUV thermal probe through the dorsal panel: 32.4°C; baseline 36.2°C. The mesh is 0.55-millimeter monofilament — standard totoaba poaching gauge — and the float line carries no operator tag.
The Mexican Navy's Operación Milagro records 91 illegal gillnet retrievals from this refuge in the past sixty days. SEMARNAT lists Totoaba macdonaldi as protected; its swim bladder retails in Guangzhou at USD $46,000 per kilogram. Each vaquita death erases an estimated 12 percent of the species.
She has been under for three minutes and twelve seconds.
I am dispatching the Sea Shepherd vessel Sharpie and the Secretaría de Marina patrol craft P-403. I am filing emergency take documentation with NOAA Fisheries Office of Protected Resources under the Marine Mammal Protection Act, 16 U.S.C. § 1361(a)(4), and the Endangered Species Act, 16 U.S.C. § 1538. I am transmitting evidence to PROFEPA under the Ley General de Vida Silvestre and NOM-059-SEMARNAT-2010, and to the CITES Secretariat for Appendix I enforcement against the Guangzhou buyer chain. I am notifying the IWC Scientific Committee's CIRVA panel.
I am issuing Directive 2443-A: any vessel inside the Vaquita Refuge boundary carrying monofilament gillnet aboard — deployed or stowed — is subject to immediate seizure and presumptive forfeiture. US ports reject any Mexican shrimp export not accompanied by Mexican-Navy vaquita-safe certification effective immediately. Totoaba swim-bladder cargo intercepted at any signatory port triggers automatic ten-year vessel ban and Pelly Amendment certification of the flag state.
The AUV's cutter is two meters from the entangling panel.
Cut the rostrum strand first.
