Night fishing: No statewide night-fishing closure in New Jersey on most waters; some park ponds and reservoirs have their own posted hours, and trout-stocked waters have specific in-season closures around stocking days (check the current stocking schedule).
Boats: The big reservoirs and glacial lakes (Round Valley, Spruce Run, Hopatcong, Greenwood, Swartswood, Merrill Creek) take trailered boats via a state ramp, most with a horsepower or electric-only limit; Pine Barrens rivers and smaller lakes are canoe/kayak/car-top.
Bank & bivvy camping: Camp at New Jersey state parks and forests near many of these waters (Round Valley, Swartswood, Stokes, Wharton, Bass River, Belleplain); Wildlife Management Area waters are day-use only.
Tackle: Statewide bass, pickerel and panfish limits apply unless posted; trout water needs the Trout Stamp and follows seasonal and in-season-closure rules, with several fly-fishing-only and catch-and-release special-regulation reaches. Check the current NJ Freshwater Fishing Digest for this water.
