Population Dynamics Branch Management

Russell Brown, Ph.D., Branch Chief

Dr. Russell Brown with white hake

The Branch Management Task is responsible for providing technical oversight for all activities carried out by the different stock assessment and research groups of the Population Dynamics Branch. Oversight requires review of documents, presentation materials, responses to correspondence and action items given by the Branch as scientific input to the fishery management process. Additionally, the Branch conducts research on stock assessment methods and factors that influence the changes of fish populations. Prioritization of this research is a major duty of the Management Task.

Management also provides liaison activities (participation in meetings, channeling of information requests) with the New England and Mid-Atlantic Fishery Management Councils.

The Population Dynamics Branch is responsible for monitoring the abundance of fish stocks, measuring the impact of fishing activity, and evaluating interactions among the living elements of the ecosystem. Evaluations of commercial and recreational sampling for assessed stocks are also included in stock assessments. To check stock abundance and fishing activity data collected by NEFSC and other resources are used.

Branch Assessment Working Groups and Stock Assessment Review Committees summarize information on the status of fishery resources and presented to fishery managers at Stock Assessment Workshops. Scientific papers are prepared to describe research results and staff members frequently help in assessments of fishery resources in the Northwest and Northeast Atlantic beyond the control of the US. Frequent cooperation with both national and international colleagues is required.

To determine the effects of environmental changes and fishing activity on fishery resources, mathematical and statistical models are used and considerable effort given by the Branch towards developing new methods for studying the distribution of fishery resources and fishing activity.
