1 Descriptive Section

1.1 Indicator category

[1] “Fishery”

1.2 Indicator name

Aquaculture Production

Includes variable(s): Pieces, Production/Acre, Shellfish lease Acres

1.3 Indicator brief description

Oyster production: number of oysters harvested from aquaculture.

1.4 Indicator visualization

Overall, oyster production has generally increased and production per area has also improved. Aquaculture reporting is state specific, which can make it difficult to collate in a meaningful way. However, reporting coverage is improving year to year as aquaculture increases across the coast. The data included here only include oyster numbers at this time. Data after 2017 have decreased but, due to a lack of data from recent years, it is unclear if this has continued.

[Classify by hand, note gridded data if available could be applied to different species ranges]

2.1.2.5 Uncertainty metrics

Uncertainty is captured in these variables:

character(0)

2.1.3 Are methods clearly documented to obtain source data and calculate indicators?

Yes

2.1.3.1 Can the indicator be calculated from current documentation?

2.1.3.2 Is code publicly available? up to date?

2.1.3.3 Have methods changed over time?

Yes

2.1.4 Are indicator underlying source data linked or easy to find?

Source data are publicly available

2.1.4.1 Where are source data stored?

Data was synthesized from state specific sources, listed below. State of Maine, Department of Marine Resources. State of New Hampshire, Marine Aquaculture Compendium State of Massachusetts, Division of Marine Fisheries State of Rhode Island, Coastal Resource Management Council State of Maryland, Aquaculture Coordinating Council

2.1.4.2 How/by whom are source data updated? Are future updates likely?

Chris Schillaci christopher.schillaci@noaa.gov

[likelihood of source data updates requires judgement, enter by hand]

2.1.4.3 How often are they updated?

[Update by hand, look for source, may require judgement]

2.2 Indicator analysis/testing or history of use

2.2.1 What decision or advice processes are the indicators currently used in?

Aquaculture can produce seafood as well as other products. Here we summarize available data on aquaculture production from the Northeast US.

2.2.2 What implications of the indicators are currently listed?

Aquaculture production contributes to overall seafood production in the Northeast US. This indicator provides only a portion of aquaculture production in the region, but increases in this portion are apparent across the whole time series. Recent decreases (since 2017) may indicate a downward change in this aquaculture portion; however, there is not enough data from years following 2017 to indicate any significant decreasing trends.

2.2.3 Do target, limit, or threshold values already exist for the indicator?

2.2.4 Have the indicators been tested to ensure they respond proportionally to a change in the underlying process?

2.2.5 Are the indicators sensitive to a small change in the process, or what is the threshold of change that is detectable?

Unknown

2.2.6 Is there a time lag between the process change and the indicator change? How long?
