(a) The Secretary of the Interior may upon request of an Indian tribe, request of a State Governor, or upon his own motion, and upon finding that Federal regulation of Indian fishing in any waters in which Indians have a treaty-secured nonexclusive fishing right is necessary to assure the conservation and wise utilization of the fishery resources for the present and future use and enjoyment of the Indians and other persons entitled thereto, promulgate regulations to govern the exercise of such treaty-secured fishing right in such waters for the purpose of preventing, in conjunction with appropriate State conservation laws and regulations governing fishing by persons not fishing under treaty rights, the deterioration of the fishery resources.

(b) In formulating such regulations the Secretary of the Interior may incorporate such State laws or regulations, or such tribal regulations as have been approved by the Commissioner of Indian Affairs, as he finds to be consistent with the Indians' rights under the Treaty and the conservation of the fishery resources.

(c) Before promulgating such regulations the Secretary of the Interior will seek the views of the affected Indian tribes, of the fish or game management agency or agencies of any affected State, and of other interested persons. Except in emergencies where the Secretary finds that the exigencies require the promulgation of regulations to be effective immediately, a notice of proposed rule making will be published in the Federal Register in accordance with 5 U.S.C. 553 to afford an opportunity to submit comments and information, at such times and in such manner as may be specified in the notice. In the event of the emergency promulgation of regulations, interested persons will be afforded, as soon as possible, an opportunity to request amendment or revocation thereof.

(d) Any regulations issued pursuant to this section shall contain provisions for invoking emergency closures or restrictions or the relaxation thereof at the field level when necessary or appropriate to meet conditions not foreseeable at the time the regulations were issued.

(e) Regulations issued pursuant to this § 249.2 may include such requirements for recording and reporting catch statistics as the appropriate state fish and game agencies or the Secretary of the Interior deem necessary for effective fishery management.
