Catfish, carp, bluegill. Get hooked and head to the Dock & Community Boathouse at Bartram's Garden every Wednesday through August 30 for a relaxing day of free fishing. That means the equipment, bait and basic instruction cost nothing. All ages welcome and no experience, fishing license or pre-registration required. But there’s one catch: You can’t take your prized catches home with you: Catch and release only. Reel in more than 40 species of fish in the Tidal Schuylkill River including channel catfish, white perch, common carp, bluegill and American eel. Join the weekly free catch-and-release fishing in spring and summer or borrow a rod and tackle from the Welcome Center. Visitors can fish at any time from this public dock or from other riverfront spots along the North and South Mile. Live bait is available to buy from a vending machine in the Barnyard by the Welcome Center. Free, 5 p.m. to 8 p.m., Bartram’s Garden, 5400 Lindbergh Blvd., 215-729-5281, e-mail: [email protected] or Bartramsgarden.org.
