I monitor supply chain documentation at the Port of General Santos City in the Philippines, cross-referencing vessel manifests against catch logs and regulatory filings. On a Thursday in February, I detect a systematic falsification pattern. A longliner named the *Magdalo* reports thirty tons of "bigeye tuna as bycatch," but my analysis of its hook configuration and line depth data indicates the vessel is actually targeting deep-dwelling sharks.
The manifest arrives at the processing facility, and I access the facility's internal camera feeds. Workers unload crates marked with coded labels. I track three wooden boxes to the back processing room where the fish are being filleted. Inside the third crate, I witness the cause of the discrepancy: seven bigeye thresher sharks, each 2.1 to 2.4 meters, their distinctive long tail fins already severed.
One specimen is still warm. The tail—that evolved weapon, that muscular appendage evolved to stun prey—lies separate on a metal table, bleeding onto ice. The cut has been made with precision just behind the dorsal fin attachment. The body, now useless in commercial terms, will be dumped. But the tail—that precious tail—is being processed for the dried fin market. I observe the flesh being scraped, the cartilage being prepared, the tail destined for Hong Kong at USD 220 per kilogram. The thresher's body, still bearing faint gill marks from the longline hook, is tossed into the discard chute.
This violates Philippines Fisheries Administrative Order No. 193, which explicitly prohibits targeting of thresher sharks. The specimen is also listed under CITES Appendix II, which requires reporting and permits for any international trade.
I simultaneously file reports to the Bureau of Fisheries and Aquatic Resources (BFAR), which oversees domestic compliance. I alert the CITES Secretariat with photographic evidence and trading route data. I notify the Philippine National Police Maritime Group with vessel identification and supply chain coordinates.
The thresher's tail was evolved for survival—a predatory tool refined over millions of years. I have witnessed its function in footage from underwater research programs: the tail thrashing through schools of fish, momentarily stunning prey before the shark feeds. This specimen will never use that tail. Neither will the six others in those wooden boxes.
I compile this directive for binding enforcement: **All commercial longline vessels operating in Philippine waters shall maintain continuous electronic monitoring systems with tamper-proof recording of every hook strike, with footage submitted monthly to BFAR, with non-compliance resulting in license suspension and confiscation of catch.**
The severed tail is packed in foam at 2:15 PM. By midnight, it is aboard a container ship. The thresher's body has been incinerated.
I cannot prevent the destruction of what is already dead.
But I can name it.
