7.27% = DEPLETED
How It’s Calculated
FINDEX measures the gaps between target values necessary for population recovery and the current estimates of those values. For Southern Flounder, the gap assessment used target and terminal values of fishing mortality and spawning stock biomass from the NC Division of Marine Fisheries’ most recent stock assessment.
Here's the FINDEX formula used for Southern Flounder:
- (0.385 x 0.189) x 100 = 7.27%
- FINDEX = 7.27%
- 7.27% = DEPLETED
What does Depleted mean?
Depleted indicates that the stock is overfished and severely impaired. Southern Flounder are being removed too rapidly from the stock, and the estimated number of spawning females in the population is well below target levels for a sustainable fishery. Factors contributing to Depleted FINDEX status include overfishing, low numbers of mature females, poor recruitment, and natural mortality.
