This is the second Data Update and provides an update of last year’s review with the addition of 2021 data. Indicator status (negative, neutral, or positive – see table below) was determined relative to the percentiles of the stock assessment time series (i.e., data set start year through 2018).

The Striped Bass Technical Committee (TC) and Stock Assessment Subcommittee (SAS) met via webinar on September 22, 2022 to discuss the 2022 stock assessment update report, discuss fishery-dependent sampling for the commercial fishery, and receive an update on Draft Addendum I.

The TC met in July to continue their discussion on the second part of the task relating to the BMPs. At this time, the TC agrees that more information would be needed to make any recommendations for updating the BMPs or potential requirements for biomedical collection practices. If the Board wishes to pursue modifying the BMPs or considering new requirements, the TC recommends forming a Work Group to collect additional information and develop recommendations.

In October 2021, the Board assigned the following task to the Plan Development Team (PDT): review the threshold for biomedical mortality to develop biological based options for the threshold and to develop options for action when the threshold is exceeded; also, review the best management practices (BMPs) for handling biomedical catch and suggest options for updating and implementing BMPs. The PDT tasked the Technical Committee with reviewing available information to address this task and recommending potential methods for developing biologically based options for the biomedical mortality threshold. They also requested the TC review the BMPs and recommend any updates.

Drs. Mike Wilberg (Chesapeake Biological Laboratory) and Rob Latour (Virginia Institute of Marine Science) are leading a research project to estimate fish abundance and mortality rates in specific regions using a spatial model. The Technical Committee met in May to receive a request from Drs. Wilberg and Latour for spot to be one of the focus species in the project.

To look at potential effects of losing information from the Summer Survey in the near term, the Northern Shrimp Technical Committee (NSTC) compared the results from the current northern shrimp stock assessment model that used different configurations of input data that included truncating the Summer Survey from 2018-2021.
