Natural mortality was estimated at 0.17/yr. Age at maturity was estimated at 11 years for males and 15 years for females. Results of the demographic analysis showed that the population, in the absence of fishing mortality, was stable and not significantly different from zero and particularly sensitive to overfishing. At the current age at first capture and natural mortality rate, the fishing mortality rate required to result in negative population growth was low at F>0.004/ yr. Elasticity analysis revealed that juvenile survival was the principal factor in explaining variability in population growth rate.]]> Mon 13 May 2024 14:49:17 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:35711 Mon 13 May 2024 14:48:28 SAST ]]>
