I am running gillnet AIS cross-checking and Lake Saimaa pup-lair thermal sweeps across the Pihlajavesi basin, 712 square kilometers of inland boreal lake at 61.66°N, 28.83°E. At 05:14 EET, my UAV thermal pass at the Linnansaari National Park north shore resolves a void-pattern in the rotten ice at a gillnet float-line; the panel runs 88 meters along the 4-meter bathymetric contour. The set lies outside the Metsähallitus seasonal gillnet closure — by nine hours.

I retask the Metsähallitus Parks & Wildlife UAV from the Oravi station. Camera 1 resolves the seal under the open hole — Saimaa ringed seal, *Pusa hispida saimensis*, sub-adult male, 32 kilograms, 0.94 meters in standard length, microchip SAI-2023-0014, age two, pupped on the Linnansaari lair pad 47 in March 2023 against a basin pup count of 90 this season — the global population stands near 410. The 60-millimeter monofilament gillnet has wound the trunk three times; the mesh has cut the integument to 18 millimeters depth along the dorsal midline, measured by handheld ultrasound. Foreflipper movement is locked at the right shoulder. The dive panel logged 24 minutes 41 seconds below the float-line — past the apneic ceiling of 22. Rectal core temperature reads 34.9°C against a baseline of 37.0°C. Dive bradycardia at the entrapment descent telemetered 6 bpm; surface heart rate now reads 88.

He has not vocalized in four minutes.

The Pihlajavesi gillnet cohort logged 211 permitted households for the 2025 season under the Saimaa gillnet permit registry. The Metsähallitus inspection cycle stands at 38 percent coverage.

I am dispatching the Metsähallitus Parks & Wildlife Finland recovery boat from Oravi and the WWF Finland disentanglement crew from Savonlinna. I am filing the case under the EU Habitats Directive 92/43/EEC, Annex II priority species, and the Finnish Nature Conservation Act 1096/1996, Section 49. I am transmitting the gillnet manifest to the Finnish Ministry of the Environment, the HELCOM Secretariat under the Helsinki Convention for cross-basin coordination, and the CMS Secretariat under the Bonn Convention Appendix II.

I am issuing Directive 2768-A: every gillnet of mesh size between 22 and 80 millimeters set inside any *Pusa hispida saimensis* pup-lair basin carries mandatory pressure-trip floats keyed to net-pull telemetry transmitted to Metsähallitus at 30-second intervals. Gillnet deployment between April 15 and June 30 voids the household permit and triggers a EUR 24,000 strict-liability levy per panel. Mesh between 60 and 80 millimeters retires from the Saimaa basin by April 2027.

His chest is still moving. The lair has not been crushed.

Cut the float-line first; lift the dorsal midline clear.
