Lineage Statement:

NOAA Fisheries Science Center representatives compile stock assessment information and assessment results (summary data, time series and survey-assessment linkages) for entry in the SIS database after stock assessments are considered final (i.e. have completed their regional peer review processes and are available for use as advice to managers). Stock assessment refers to the processes of collecting, analyzing, and reporting demographic information for the purpose of determining the effects of fishing on fish populations. Assessments involve some sort of quantitative data analysis and provide information necessary to estimate the current abundance and exploitation rates of resources relative to predefined goals. Assessment information include: update to a trend analysis using the most recent catch and abundance index to provide an updated status report; interpretation of the most recent survey abundance data as absolute biomass, multiplying by target exploitation rate, and providing updated quota recommendations; incorporation of the most recent data into a dynamic model and using the results to update status determinations, quotas, etc. Simple data reports (catch reports, report of abundance index from a recent fishery-independent survey, report on a data workshop for data that could be used in an assessment) do not qualify as assessments and are not routinely entered into SIS. Stock assessments that do not pass their technical regional peer review are included in SIS but are limited to reflect the descriptive information about the assessment (i.e. the attempted level of effort for the assessment, review process, and citation).

2. An assessment record is created for a SIS entity (e.g. stock or stock complex) and includes assessment summary information, assessment time series, and assessment-survey links. To create an assessment record, the Science Center representative selects an entity and enters the assessment summary information including:

1) Assessment Year and Assessment Month

2) Assessment Model

3) Model Version

4) Lead Lab

5) Point of Contact

6) Update Type:

7) Review Type

8) Levels of Life History data

9) Levels of Stock Assessment

10) Levels of Stock Assessment

11) Levels of Catch Data

12) Levels of Abundance Data

13) Citation:

14) Fishing Mortality Rate (F) Related Data

15) B (biomass) Related Fields

3. After an assessment record has been created in SIS, time series information can be entered. The time series entry is associated with an individual assessment record in SIS. Time series data can include data inputs and/or model outputs and are used to show trends in population and fishing effort. Each set of time series data must contain the following descriptive fields: time series year, parameter category, data type, primary flag, data source, basis, range, statistic, and scalar as well as the time series value.

4. After an assessment record has been created in SIS, the Science Center representative can add assessment-survey links. This information is used to track fishery-independent surveys and other inputs used as abundance indicators in stock assessments. The overall assessment-survey link entry is associated with an individual assessment record in SIS and survey links are created for each abundance indicator/survey used or explored in the stock assessment. Survey link records contain the following data inputs: survey name or other category; notes (if needed); and influence degree.
