NOAA Fisheries' Office of Science and Technology has commissioned an independent, expert peer review to assess the quality and credibility of the proposed calibration model to be used to update the historical recreational fishing estimates produced using the current FES to the scale of the revised FES anticipated for implementation in January 2026.
Fishing Effort Survey Background
As part of the Agency's continuous evaluation and improvement process, NOAA Fisheries has been researching improvements to the FES, which is a key survey component of the Marine Recreational Information Program (MRIP) that estimates recreational fishing effort—specifically, the number of fishing trips taken by shore and private boat anglers from Maine to Alabama and in Hawaii. The current FES mail survey design was implemented in 2018 and replaced the legacy Coastal Household Telephone Survey (CHTS) to address declining response rates and coverage issues associated with landline telephone surveys.
Throughout 2024, NOAA Fisheries conducted a large-scale study to test improvements to the FES based on results of prior pilot studies. The tested design increased the administration of the survey from every 2 months to monthly and changed the order of two fishing effort questions to improve respondent reporting. Based on the study findings and pending peer review results of the study report and proposed design (anticipated in late fall 2025), the Agency plans to implement a revised FES design.
Calibration Model Background
To assure continuity and comparability of recreational fishing effort estimates through survey design changes, NOAA Fisheries' team of statistical consultants developed a calibration model. This model updates historical estimates produced by the current FES to estimates that would have been produced had the revised design been in place prior to 2026. This updated calibration model incorporates and builds upon the peer-reviewed model developed to calibrate the historical estimate time series from the CHTS to the current FES.
Peer Review and Workshop Objectives
The objective of this peer review was to evaluate the effectiveness and suitability of the proposed calibration model for re-estimating historical estimates of private boat and shore fishing effort. It is a vital step in NOAA Fisheries' commitment to enhancing the quality and reliability of recreational fishing data. Insights gained from the peer review will inform the finalization of the calibration model and guide its application in updating historical effort estimates, ensuring fisheries stock assessment and management continue to be based on statistically robust and consistent catch and effort data. The final peer review report outlining findings and recommendations was completed and submitted to NOAA Fisheries in late 2025.
Day 1 of the workshop focused on technical presentations and discussion regarding objectives of the peer review; the 2024 FES study; background on calibration purpose and needs; and a walkthrough of the updated calibration model methodology, assumptions, and model outputs. In addition, partners and the public had the opportunity to raise questions and concerns regarding the presented information. Day 2 of the workshop included a Q&A with the calibration model developer and panel-only sessions for initial model assessment discussions and report planning.
