Improving the Use of Habitat Information in Stock Assessments

The Office of Science and Technology provides support to NMFS scientists for habitat assessment research projects.  A major focus of the Habitat Assessment Improvement Plan (HAIP) is to improve stock assessments through the incorporation of benthic and pelagic habitat information. While many stock assessments do not currently incorporate habitat information directly into the assessment models, habitat data is important to other areas of the stock assessment process. This effort is designed to improve the availability and utility of habitat information in support of the stock assessment process for stocks managed Federal Fishery Management Plans, with an emphasis on stocks listed under the Fish Stock Sustainability Index (FSSI). Each year 3 to 6 habitat assessment projects are selected for funding.
