Resilience / productivity: |
Vulnerable to extinction if decline in biomass or numbers exceeds threshold over the longer of 10 years or 3 generations. |

Intrinsic rate of increase (rm): | /year |
Lr = cm
Estimated from Fmsy at Lc = length of recruitment (Lr). |

Note: The estimates are derived from default values taken from FishBase and will thus not be appropriate for every population. You can change these values and recalculate the life history parameters.
