N.J. Stat. § 23:4-22.4
The Board of Governors of Rutgers, The State University, shall direct the Department of Wildlife Management at Cook College to conduct a study to identify or develop an animal trap which substantially reduces injury and pain to both targeted and nontargeted animals which are caught in the trap and which could serve as an alternative to the steel-jaw leghold type animal trap. The results of this study shall be published in a report to the New Jersey Fish and Game Council, hereinafter referred to as the "council," in the Department of Environmental Protection within one year of the effective date of this amendatory and supplementary act. For the purposes of this amendatory and supplementary act, the steel-jaw leghold type animal trap does not mean mouse and rat traps designed for use in or under buildings.
