Summary

Bycatch and habitat impacts: Fishing method is highly selective with no bycatch or seafloor impacts.


Abundance: Despite the low environmental impact and high selectivity of these gears, uncertainties in stock status remain. Specifically, there is limited information regarding overall decline in population size and current rate of recovery, as well as uncertainty in the age at which this species reaches maturity and breeds. These two issues present data gaps in stock assessments, which in turn cause challenges for making strong management decisions based on accurate science.
