Bonus Program Logbooks

• Striped Bass Bonus Program VAS

• Implemented 1993 (paper), 2007 (online)

• Specific to striped bass– Catch, effort, harvested lengths

• Stock assessments, management options

• Thousands of individuals at peak; less than 100 in 2011– Less incentive to participate– Still good participation from party/charter vessels

• Program being phased out

NJ VAS Overview

• Implemented June 2008

• Similar to MRFSS– Trip info, catch info, lengths

• Marine waters of NJ and surrounding area

• Voluntary, internet based, open access

Objectives

• Supplement/complement MRIP data

• Fill data gaps– Wave 1– Length data, particularly discards

• Address concerns of constituents– “I’ve never been interviewed!”– Alternate management scenarios

Primary uses to date

• Length frequency data for regional stock assessments– Fluke– Black sea bass

• Development of fluke management strategies– Strategies not supported by MRIP data– Still requires MRIP effort data

• Not enough Wave 1 data to do anything with yet

• Many key species without much data

Performance comparison - fluke

• 2009 NJ recreational fluke quota 809,000 fish = 2.8 million lbs

• MRIP estimated harvest– 107% of quota (revised)

• VAS estimated harvest– 110% of quota (effort data through 2009)

Page 14: New Jersey Voluntary Angler Survey(s) Jeff Brust and Maryellen Gordon NJ Division of Fish and Wildlife Volunteer Angler Survey Workshop Baltimore, MD February

Future directions

• Roll striped bass and general surveys into single survey

• Outreach to increase participation

• Individual user accounts

• Annual summaries of reported data

• Increased IT and analytical staff support
