30.76% = DEPLETED
How It’s CalculatedFINDEX measures the gaps between either target or threshold reference values necessary for population recovery and the current, or “terminal”, estimates of those values.
Here's the FINDEX formula used for Weakfish:
For Weakfish, the gap assessment compared threshold and terminal values of total mortality (fishing mortality + natural mortality) and spawning stock biomass from the Atlantic States Marine Fisheries Commission’s most recent stock assessment model. No target reference values for spawning stock biomass have been established for Weakfish. The terminal year in the stock assessment model was 2017.
- (0.986 x 0.312) x 100 = 30.76
- FINDEX = 30.76%
- 30.76% = DEPLETED
What does Depleted mean?Depleted indicates that the stock is overfished and severely impaired. Weakfish are being removed too rapidly from the stock, and the estimated number of spawning females in the population is well below threshold levels for a sustainable fishery. Factors contributing to Depleted FINDEX status include overfishing, low numbers of mature females, and poor recruitment. High rates of natural mortality have also been observed for Weakfish with predation and competition offered as potential sources.

- North Carolina’s state record Weakfish was landed at Nags Head in 1980 by Sterling Ammons
- The record-breaking fish weighed 14 pounds, 14 ounces
Did you know?
- Weakfish are considered 90% mature at age 1, although older females spawn more frequently and carry more eggs
- The maximum age recorded for a Weakfish was 17-years for a fish from Delaware Bay
- Weakfish spawning in North Carolina occurs in sounds and estuaries and peaks from April to June
