SMART Indicator Report: Aquaculture Production

1 Indicator category

[Fill by hand, needs decision by Council]

2 Indicator name

Aquaculture Production

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

3 Indicator brief description

Oyster production: number of oysters harvested from aquaculture.

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.

[Build link to Tech-doc, look for current and previous methods]

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

[Build link to Tech-doc, look for source, may require judgements]

5.4.1 Where are source data stored?

[Build link to Tech-doc, look for source, may require judgement]

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

6 Indicator analysis/testing or history of use

6.1 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.

6.2 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.

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

[Fill by hand; if not in key results or implications, likely does not exist]

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

[Fill by hand; if not in introduction, key results, or implications, likely not tested]

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

[Fill by hand; if not in introduction, key results, or implications, likely not tested]

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

[Fill by hand; if not in introduction, key results, or implications, likely not tested]
