Striped Bass Volunteer Angler Survey — Join Us!

Do you like to fish for striped bass in N.H.? Tell N.H. Fish and Game’s Marine Division about your striped bass fishing — and you could win a great prize!

For the Striped Bass Volunteer Angler Survey, anglers are asked to provide information such as amount of time fished and length of fish caught. Completed trip logs may be sent by mail, or an electronic logbook can be filled out online at fishnh.com/surveys/striped-bass.html. Marine fisheries biologists use the results to assess the status of striped bass populations each year.

How do I get started? Contact the Marine Division at Reg3@wildlife.nh.gov or (603) 868-1095 to get your logbook by mail or e-mail. Submit your logs by November 1, for a chance to win a framed print of “Shadow” by Victor E. Young, donated by the Coastal Conservation Association of N.H. and a saltwater rod & reel donated by Kittery Trading Post. Thanks for your help!
