Warmwater Surveys


New Jersey has over 400 impoundments open to the general public for fishing and thousands more in private ownership scattered throughout the state. These lentic environments offer excellent fishing opportunities for a variety of species such as bass, sunfish, crappie, and pickerel. These species naturally reproduce in the waterways and often do not require active stocking to sustain their populations.

Although mostly self-sustaining, the Bureau of Freshwater Fisheries monitors these populations through boat electrofishing surveys on lakes and ponds throughout the state to assess the current status of warmwater fish populations. Sampling results are used to determine if additional management measures such as supplemental stockings and/or adjustments to current regulations are necessary.

Reproductive Checks
Shoreline seining is also conducted in ponds in July through mid-September to collect young-of-the-year and juvenile fish to assess the extent to which popular game species and forage are reproducing. Documenting reproductive success helps assess stocking success or need as well as compliment other fisheries survey efforts such as electrofishing. These data are also beneficial in documenting the presence of both native and invasive species. Reproductive checks were conducted on 21 lakes in 2015.
