Total number of different small fishing boats fishing today in the ZTA Buffer Zone: 0.
Clam divers started to arrive at the ZTA around 6:30 and stayed in the central area, except a couple that were closer to the border to the north. During a couple of hours in the morning we work together with three Navy boats to retrieve the last part of a ghost net in the northwest area of the ZTA (the number of diver boats may vary because of the lesser visibility we had of the center of the ZTA during the operation).
During the morning around 25 small boats crossed to the northeast area of the Vaquita Refuge, which were visible when we approached the area in the afternoon.
Then starting around 17:00, small boats crossing activity increased. Between, 17:00 and 20:00, 17 small boats were seen crossing the ZTA southwest towards San Felipe.
