1 General Framework and Specialized Approaches to Monitoring U. S
General Framework and Specialized Approaches to Monitoring U.S. Marine Recreational Fisheries John Foster Recreational Fisheries Statistics Branch Chief Science and Technology, NOAA Fisheries June 20, 2017

2 Marine Recreational Information Program
The state-regional-federal partnership responsible for developing, improving, and implementing surveys that measure how many trips saltwater anglers take, and how many fish they catch. This vital information – combined with other data, such as commercial catch and biological research – enables scientists and managers to assess and maintain sustainable U.S. fish stocks.

3 MRIP Approach 2. Deliberate, well-articulated process
Executive Steering Committee Operations Team Registry Communications and Education Team Information Management Team Transition 1. Stakeholder-inclusive governance and team leadership 2. Deliberate, well-articulated process 3. Regional implementation Address Fundamental Design Issues Design, Review, and Certify New Methods Implement Improvements Scale Up to Enhance Precision, Timeliness and Coverage

4 Regional Implementation Plans
MRIP’s regional partners develop unique implementation strategies Identify data collection needs Selection of preferred survey methods from among MRIP-certified designs Priorities for improved timeliness, precision, coverage for each region Special needs (rare event, pulse fisheries, e.g., HMS, snowy grouper)

5 Estimating Recreational Fishing Activity
Data generated by a series of regional surveys

6 Estimating Recreational Fishery Catch

7 Key Points: MRIP has taken a deliberate approach to addressing the NRC recommendations. First addressing fundamental design issues, second designing, reviewing, and certifying new methods, and third implementing improvements. This is a continuous process and has been done in close collaboration with regional partners, stakeholders, and external statistical experts. Additional Notes: The MRIP Process is as follows: 1) Evaluating Methods Current methods, even those that have been implemented, can benefit from improvements to make sure that in a changing management environment, the best available science is used. Teams of scientists, statisticians, state partners, fishermen, and other stakeholders evaluate existing programs, making recommendations for new data collection designs and improvements to current designs. 2) Developing and Testing Improved Methods Recommendations for new methods and improvements to current methods are tested and peer-reviewed through the MRIP process to ensure the results meet the highest possible scientific standards. Methods are approved by MRIP, before they are approved for implementation by the Assistant Administrator for NOAA Fisheries. 3) Implementing Improved Methods Implementation of new and improved methods requires careful planning and difficult decisions on how to commit limited resources. MRIP works closely with regional partners to evaluate regional fisheries needs and examine tradeoffs among precision, timeliness, coverage, and more. Further, certain types of data collection options (e.g., for-hire trip reporting of catch and effort or a census of private boat landings of a species) require regulatory and enforcement components for implementation that must be considered. MRIP's role in the implementation of improved methods is to ensure that the result balances regional data collection needs and overall data quality for managing the Nation's fisheries.

8 Large Pelagics Survey (LPS)

9 Overview of the LPS Specialized survey program for estimating catch and effort of highly migratory species (HMS) Atlantic bluefin tuna highest priority species Seasonal and geographically limited to U.S. recreational Atlantic HMS fishery along mid- and North Atlantic coasts Current design uses complemented surveys approach to estimating total catch and effort

10 Current Large Pelagics Survey Complemented Telephone/Access Design
Large Pelagics Telephone Survey (LPTS) Large Pelagics Intercept Survey (LPIS) Large Pelagics Trips by Boats with HMS Permit Adj. Ratio Accounting for LP Trips by Boats without Permit Total LP Boat Trips Mean Catch per LP Boat Trip LPTS is made up of 2 separate surveys: LPTS add-on LPTS private They both have their own adjustment factors Total Catch

11 LPTS Design for For-Hire Boats
Integrated with the For-Hire Survey Sampling frame Weekly survey with simple random sampling of boats Contacts made with designated boat representatives Data collected for each reported trip targeting large pelagic species Sampling Frame Boats with Charter/Headboat category HMS permit included in FHS list frame Frame sorted to separate boats with HMS permit from those without the permit Data collected for each reported trip Number of anglers who fished Primary area of fishing, water temperature, depth, etc. Catch of Atlantic Bluefin Tuna by size class Catch of subset of other Highly Migratory Species not frequently encountered in dockside survey Monthly estimates of charter boat fishing trips for large pelagic species Reporting is mandatory

12 LPTS Design for Private Boats
Separate telephone survey Sampling frame Bi-weekly survey with simple random sampling of boats Contacts made with designated boat representatives Data collected for each reported trip targeting large pelagic species Sampling Frame Boats with Angling category or General category HMS permit Frame sorted to separate boats by permit type Data collected for each reported trip Number of anglers who fished Primary area of fishing, water temperature, depth, etc. Catch of Atlantic Bluefin Tuna by size class Catch of subset of other Highly Migratory Species not frequently encountered in dockside survey Monthly estimates of private boat fishing trips for large pelagic species Reporting is mandatory

13 Fishing Effort Adjustments Correction of LPTS Undercoverage Error
LPTS trips adjusted to account for trips on out-of-frame boats Large Pelagics Intercept Survey Collects catch data for intercepted LP boat trips Identifies boat on which angler fished Is it in LPTS sampling frame? Estimates Mean catch per LP boat trip Proportion of LP trips made on boats in LPTS frame

14 Large Pelagics Intercept Survey
Access point survey with multi-stage cluster sampling Sampling frame Sampling assignments Estimates mean catch per LP boat trip by species and Atlantic bluefin tuna size class Sampling Frame PSU is site/day Only sites with expected fishing for large pelagic species Sites clustered prior to PPS sampling Sites weighted by estimated number of LP boat trips Sampling assignments Site cluster and initial site assigned Sampler can move from site to site within cluster Since Required to canvas all sites within the assignment Time interval not fixed – most active time of day Assignment duration can vary Large pelagics boat trips intercepted Boat level interviews (captain/crew)

15 LPS Next Steps Completion of LPS re-estimation and re-design
Ad hoc MRIP Regional Implementation Team preparing an MRIP Regional Implementation Plan for Atlantic HMS. Plan will identify implementation needs and priorities, potentially including: Completion of LPS re-estimation and re-design Expansion of Atlantic HMS recreational data collections Consideration of additional improvements Re-estimation and re-design: incorporate non-response weights improve data collection on trips originating from private access sites and optimize sample sizes to improve PSE’s on rare event species Expansion of data collections through the rest of the Atlantic HMS region (NC-TX) either through an expanded LPS or addition of an offshore stratum to MRIP Consideration of additional improvements that address: for-hire electronic logbooks; targeted improvements in shark data collection expand tournament data collection to all HMS expansion of catch card programs pilot projects in the Caribbean Also under consideration for the HMS Regional Implementation Plan Option to find a way to combine surveys and, where needed, fine tune our sampling to get better estimates of offshore catch
