文摘

Automated fish measurement can greatly improve efficiency of fish resource surveys. Automated image-based length similar to physical measurements in clear water. Best results when fish are +/−20+/−20 degrees of lateral view and closer than 1.5 m. Repeated automated image-based measurements of same fish show 3% error.
