Redfish are slow growing, long-lived animals with an extremely low natural mortality rate.
Females are viviparous, retaining eggs in the ovary after fertilization until yolk-sac absorption.
Mating takes place in autumn, with subsequent larval extrusion occurring the following spring and summer. Amendment 9 established biomass rebuilding targets, and defines control rules which specify target fishing mortality rates and corresponding rebuilding time horizons. The goal of the management program is to reduce fishing mortality to levels which will allow stocks within the complex to initially rebuild above minimum biomass thresholds, and, ultimately, to remain at or near target biomass levels. The principal commercial fishing gear used to catch redfish is the otter trawl. Recreational catches are insignificant.
