Marine Stock Assessment Projects

Part of: Marine fisheries

Area of Expertise:
Services:

Research conducted at AFBI is undertaken in support of fish and shellfish stock assessments under the Marine Ecosystems Management programme.

Project: Population dynamics and assessment of Irish Sea fish and shellfish stocks.

Project Leader(s):

Dr Walter Crozier

Project Objectives

To provide the scientific data upon which stock assessments can be performed for marine fish and shellfish species through the ICES forum. These assessments contribute to the scientific advice underlying the formulation of fisheries policy. This project lies at the core of all fisheries research performed by AFBI.

Project: Recruitment process and stock dynamics of Irish Sea fin-fish populations

Project Leader:

 Dr Steven Beggs

Project Objectives

To provide scientific understanding of fin-fish stock dynamics and recruitment process to facilitate current management decisions and underpin the development of an ecosystem approach to the sustainable management of the Irish Sea fin-fish resource.
