(a) Vessel owners or operators engaged in any commercial fishery must report all incidental mortality and injury of marine mammals in the course of commercial fishing operations to the Assistant Administrator, or appropriate Regional Office, by mail or other means, such as fax or overnight mail specified by the Assistant Administrator. Reports must be sent within 48 hours after the end of each fishing trip during which the incidental mortality or injury occurred, or, for nonvessel fisheries, within 48 hours of an occurrence of an incidental mortality or injury. Reports must be submitted on a standard postage-paid form as provided by the Assistant Administrator. The vessel owner or operator must provide the following information on this form:
(1) The vessel name, and Federal, state, or tribal registration numbers of the registered vessel;
(2) The name and address of the vessel owner or operator;
(3) The name and description of the fishery, including gear type and target species; and
(4) The species and number of each marine mammal incidentally killed or injured, and the date, time, and approximate geographic location of such occurrence. A description of the animal(s) killed or injured must be provided if the species is unknown.
(b) Participants in nonvessel fisheries must provide all of the information in paragraphs (a)(1) through (a)(4) of this section except, instead of providing the vessel name and vessel registration number, participants in nonvessel fisheries must provide the gear permit number.
