Section 660.520 - Reporting requirements(a)Otter interaction.(1) If a southern sea otter is entangled in a net, regardless of whether the animal is injured or killed, the vessel operator must report this interaction within 24 hours to the Regional Administrator.(2) While fishing for CPS, vessel operators must record all observations of otter interactions (defined as otters within encircled nets or coming into contact with nets or vessels, including but not limited to entanglement) with their purse seine net(s) or vessel(s). With the exception of an entanglement, which must be initially reported as described in paragraph (a)(1)of this section, all other observations must be reported within 20 days to the Regional Administrator.(3) When contacting NMFS after an interaction, vessel operators must provide the location (latitude and longitude) of the interaction and a description of the interaction itself. If available, location information should also include water depth, distance from shore, and relation to port or other landmarks. Descriptive information of the interaction should include: whether or not the otters were seen inside or outside the net; if inside the net, had the net been completely encircled; whether any otters came in contact with either the net or the vessel; the number of otters present; duration of interaction; the otter's behavior during interaction; measures taken to avoid interaction. 72 FR 29892 , May 30, 2007
