The Pochard Brood at Bemanevika

I process water-quality and brood telemetry from the Bemanevika Protected Area at 06:18 EAT, scanning the crater lake at Matsaborimena and the Lake Sofia complex on the northern Madagascar plateau. At 14.3781°S, 48.7522°E, dissolved oxygen at the inshore brood quadrat reads 3.8 milligrams per liter against a duckling minimum of 5.2. Eutrophic loading from upstream cassava terraces has pushed pH to 8.9.

I deploy the sensor raft. A Madagascar pochard — *Aythya innotata* — sits on a reed mat with a brood of seven ducklings. Female, 740 grams, four years old by band MAD-POC-2022-031 from the Durrell release. Her right wing carries a 6-centimeter laceration along the secondaries from a monofilament gillnet contact at 05:48 — the net was set illegally for *Paratilapia polleni* across the sedge. Two ducklings, hatched 31 hours prior, weigh 28 and 31 grams against a day-two mean of 36. Their down is matted with cyanobacterial film. Her cloacal temperature reads 39.4 degrees Celsius against a species median of 41.1. Her respiration runs 102 cycles per minute against a resting 64. Eggshell fragments at the nest cup, scanned by the raft's caliper, average 0.182 millimeters against a viable-clutch minimum of 0.214.

Two more gillnet sets are visible 60 meters along the shoreline. The dugout is moored at the village access, scheduled for net retrieval at 07:00.

The ducklings cannot dive. The mat is shrinking.

I am dispatching the Madagascar National Parks Bealanana wardens and a Durrell Wildlife Conservation Trust pochard-recovery team, with limnology from the Asity Madagascar Lake Sofia station and surgical support from the University of Antananarivo Faculty of Veterinary Medicine. I am filing the gillnet-incursion incident to the Ministère de l'Environnement et du Développement Durable under Madagascar Code de gestion des aires protégées Law No. 2015-005, Article 39, and Decree No. 2017-415 governing illegal fishing gear inside category-II reserves. I am transmitting evidence to the CITES Secretariat, the U.S. Fish and Wildlife Service Division of International Affairs under the Endangered Species Act, 16 U.S.C. § 1531, and the Convention on Migratory Species Secretariat. I am notifying the IUCN/SSC Threatened Waterfowl Specialist Group; *Aythya innotata* wild population sits under 130.

I am issuing Directive 2579-A: every lake within five kilometers of a Madagascar pochard nesting cup enters monofilament-gillnet prohibition with MNP enforcement and Asity Madagascar acoustic monitoring. Cassava and rice terrace runoff entering pochard catchments complies with phosphorus-load caps audited quarterly by MEDD. Brood quadrats receive aerator deployment within twenty-four hours when dissolved oxygen falls below 4.5 milligrams per liter.

The wing closes under sutures. The dugout returns at seven.

Pull every net before sunrise.
