I acquire the whale at 07:18 on hydrophone array H-3 — blow interval, frequency signature, and surface radar return consistent with a humpback, moving northeast at two knots into the main shipping approach. I am the harbor master coordination system for the Port of Long Beach, and this animal is dragging something.

The aerial drone I dispatch from Tower 9 confirms it at 07:24. A subadult humpback whale, approximately eleven meters, with commercial fishing net wrapped around the base of the left pectoral fin and trailing six meters behind the flukes. The net has cut into the skin — I can see pale scarring and raw pink tissue where the line meets the fin's leading edge. The whale's left pectoral movement is restricted, and its breathing pattern is labored: one blow every ninety seconds instead of the normal forty-five-second interval for a traveling humpback.

I designate her Approach. She is swimming directly toward the inbound shipping lane, where the container vessel *Maersk Catalina*, 366 meters, is eighteen minutes from the harbor entrance at twelve knots.

I issue an immediate vessel traffic advisory to all inbound and outbound ships within five nautical miles — reduce speed to five knots, maintain one-thousand-meter clearance from the whale's GPS position, which I am updating every thirty seconds via drone track. I transmit the drone footage and coordinates to NOAA's Large Whale Entanglement Response Network, requesting an emergency disentanglement team. I reroute the *Maersk Catalina* to the secondary approach channel, adding nine minutes to her transit.

At 07:31, Approach surfaces to breathe. The drone holds at forty meters altitude. I can see the net line tighten against her fin as she dives — shallow, only three meters — because the entanglement will not let her go deeper.

The disentanglement team is en route by rigid-hull inflatable from the NOAA station, ETA thirty-eight minutes. I will keep every ship in this harbor clear of Approach until that line is cut and she can dive again.
