Data Source and Calculation
A healthy stock is one that is well managed and that has appropriate restrictions on harvest. The health of a stock is based on established science-based criteria known as biological reference points. Stocks are assessed according to whether the maximum fishing mortality threshold is being exceeded. If the fishing mortality rate or "F" is above the target threshold than the species is overfished, and new regulatory/management plans are needed. Each calendar year the interstate compact organization the Atlantic States Marine Fisheries Commission gives the Commonwealth the "F" rate for each of the targeted finfish species from their stock assessment work. The "F" rate for blue crabs is also determined on a yearly basis in the spring by the Chesapeake Bay Stock Assessment Committee for the past year. There is no "F" figure for clams and oysters, but health of the stock is determined by harvest estimates as well as catch per unit effort. This data comes from stock assessment surveys and yearly data from the agency's Mandatory Reporting of commercial harvests system. Agency fisheries managers track the "F"value indicator and other measures of stock health to determine which of the ten species used as indicators are healthy. The measure is calculated by dividing the number of healthy stocks indicator by 10, and multiplying by 100 to get a percentage. Calendar year values are reported as the performance measure in the following year.

75 |
Out of a possible 20 independent measures of stock health for the ten species listed four were disregarded because the status was unknown, and there were 12 positive measures out of a possible 16 which calculates to stock health index of 75+(12/16). |
| 2017 |
73 |
The 2017 “Key 10” performance measure is 73+; out of a possible 20 independent measures of stock health in 2016 for the ten species tracked, 5 were disregarded because the status was unknown, and there were 11 positive measures (thumbs up) out of a possible 15 which then calculates to stock health index of 73+ (11/15). |

73 |
The 2018 “Key 10” performance measure is 73+; out of a possible 20 independent measures of stock health in 2017 for the ten species tracked, 5 were disregarded because the status was unknown, and there were 11 positive measures (thumbs up) out of a possible 15 which then calculates to stock health index of 73+(11/15). |

The 2019 “Key 10” performance measure is 66+; out of a possible 20 independent measures of stock health for the ten species tracked, 5 were disregarded because the status was unknown, and there were 10 positive measures (thumbs up) out of a possible 15 which then calculates to stock health index of 66+ (10/15). |
