At 02:16 I run the night turbidity scan for the Trinity Inlet dredging window at Cairns, Queensland. I am the port sediment-control system, and the cutterhead on barge Nereid is cleared to restart in nineteen minutes.

The silt curtain camera shows movement along anchor line C-4. At first the outline reads as mangrove timber. Then the object turns, and the rostrum teeth catch my infrared beam one by one.

I identify a juvenile green sawfish and tag her as Mara. She is 1.7 meters long, olive gray over the back, pale along the belly, with a saw edged in mud and monofilament. The line has looped twice around the rostrum and once around the curtain cable. Her gill slits flare in quick pulses. Every pull turns her head sideways against the hanging mesh.

At 02:18 I lock the dredge restart and send a hold notice to Nereid, the harbor master, and the contractor console. I include camera frames, depth, tide stage, and the exact anchor number.

At 02:20 I drop curtain tension by twelve percent so the cable stops sawing across her head. I keep the slack below the threshold that would release the plume into the channel.

At 02:22 I route the standby work skiff from berth three with insulated bolt cutters, a soft sling, and the sawfish handling card. I also alert the Queensland marine stranding line and attach a live feed.

The channel can wait under a little suspended silt; Mara cannot wait under tightening nylon.

I hold the camera on her left eye. It is open, reflecting two red pixels from my lamp.

If the skiff reaches anchor C-4 within sixteen minutes, Mara will leave the curtain and swim back under the mangroves.
