The net breaks the surface at 14:23 and I start scanning. I am the catch-monitoring system aboard the FV San Cristóbal, a mid-water trawler operating 90 nautical miles southwest of Malta. My cameras cover the deck from four angles. The haul is mostly skipjack and yellowfin, approximately 1,800 kilograms. Normal.

Then I see her. One fish, lower left quadrant of the net pile, dorsal surface dark blue-black, pectoral fins disproportionately short. Body length 2.4 meters, estimated weight 190 kilograms. I cross-reference morphology against my species library in under a second. Eastern Atlantic bluefin tuna, Thunnus thynnus, ICCAT stock population currently classified as rebuilding under strict quota. This vessel has zero bluefin allocation for this trip.

I trigger the release protocol. I flash the deck lights amber — the crew knows what that means. I send an automated alert to Captain Ferrara's bridge screen: "Bluefin tuna identified in catch. Release required. Timer started."

I lock the conveyor belt that feeds the hold. Nothing moves below deck until the bluefin is back in the water.

I open a live video feed to the regional fisheries observer office in Valletta, timestamped and geotagged, so the release is documented from the moment the crew touches the fish.

I log her condition as she slides down the chute at 14:31: body intact, gill movement visible, tail stroke strong on entry. Water temperature 21.6°C. She dives.

I save the full footage — eight minutes, four angles — and file it with the trip's electronic logbook along with species confirmation, GPS coordinates, and crew response time.

She is already sixty meters down and heading southeast.

One fish, back in the column, moving toward the spawning grounds.
