Section 648.230 - Spiny dogfish Annual Catch Limits (ACLs)(a) The Spiny Dogfish Monitoring Committee shall recommend to the Joint Spiny Dogfish Committee, an ACL for the commercial spiny dogfish fishery, which shall equal to the domestic ABC (i.e., the ABC minus Canadian catch) recommended by the SSC as specified in § 648.20 . (1)Periodicity. The spiny dogfish ACL may be established on an annual basis for up to 5 years at a time, dependent on whether the SSC provides single or multiple-year ABC recommendations.(b)Performance review. The Spiny Dogfish Monitoring Committee shall conduct a detailed review of fishery performance relative to the ACL at least every 5 years.(1) If an ACL is exceeded with a frequency greater than 25 percent (i.e., more than once in 4 years or any 2 consecutive years), the Spiny Dogfish Monitoring Committee will review fishery performance information and make recommendations to the Councils for changes in measures intended to ensure ACLs are not exceeded as frequently.(2) The Councils may specify more frequent or more specific ACL performance review criteria as part of a stock rebuilding plan following a determination that the spiny dogfish stock has become overfished.(3) Performance reviews shall not substitute for annual reviews that occur to ascertain if prior year ACLs have been exceeded, but may be conducted in conjunction with such reviews. 76 FR 60642 , Sept. 29, 2011
