Fish SAR Identification and Verification• Fish SARA Permits Applicants are required to
possess formal SAR ID Training– ROM SAR Workshop (Fish ID Workshop prerequisite)
• Permits holders must learn the key identification features for all fish species at risk. – Physical Vouchers vs. Digital Vouchers?
