Section NR 1.02 - Inland fisheries management The following actions are essential to carry out an effective fish management program.
(1) LAND ACQUISITION AND DEVELOPMENT. The department shall provide for the protection of habitat essential to the maintenance of fish populations and for providing quality fishing opportunities through the acquisition of lands by gift or purchase. These lands shall be developed to provide access or be maintained as wilderness areas according to their potential.(2) HABITAT PROTECTION AND IMPROVEMENT. The department shall actively protect and maintain habitat capable of supporting aquatic species. Management efforts include deterring point and nonpoint pollution, vegetation control, rough fish control, water level manipulation and limiting shoreline development. Habitat shall be improved where fish populations can be increased and such improvements are economically and ecologically feasible. Improvements include in-stream devices, wing deflectors, bank riprap, stream bank fencing, fish shelters, dredging and streamside brushing. The application of these techniques shall be consistent with the wild and wilderness policies of the board.(3) SURVEYS AND RESEARCH. Programs shall be based on sound surveys and research. The department shall survey lakes and streams to obtain information needed to develop and implement management programs. Research shall be conducted to evaluate and resolve problems that have been defined.(4) PROPAGATION, REARING AND DISTRIBUTION.(a) The department shall rear fish for stocking in waters lacking adequate natural reproduction and where reasonable returns are demonstrated by surveys. Stocking priorities will be based on use opportunities, hatchery production capabilities, cost and habitat potential. Stocking of exotic species shall be thoroughly evaluated.(b) The department shall implement fish stocking strategies that recognize economic impact by species, provide opportunities to resident and non-resident anglers, and ensure that fish stocked are best suited to survive and thrive in the unique ecological conditions found throughout the state. These strategies shall be developed in coordination and consultation with private aquaculturists to ensure effective coordination and partnerships in protecting, sustaining and improving the genetic integrity of native, nonnative and self-sustained populations of fish of the species defined in s. NR 40.02(30) within the state.(c) Preserving the genetic integrity of fish stocks that are documented and proven to survive and thrive in Wisconsin waters is a central goal of fisheries management in Wisconsin. All fish stocking in Wisconsin inland waters shall be authorized under a permit issued by the department and shall be conducted to maintain the genetic boundaries of fish best adapted to those waters. Stocking shall be considered an important restoration tool used to reestablish naturally reproducing populations and may not be conducted to the potential detriment of natural reproduction.(d) In order to effectively meet statewide stocking goals, the department shall, on an annual basis, make available fish or fish eggs to private entities so they have access to the same genetic fish strains the state maintains in its hatchery system. This will provide additional resources and opportunities to ensure that statewide stocking needs are met through coordination and partnerships between the department and private entities.(5) POPULATION MANIPULATION. The department may, where feasible, control fish populations that are stunted or harmful to more desirable fish species. Control measures include mechanical removal, predator stocking, commercial harvest and chemical treatment.(6) RULES. The department shall regulate the sport and commercial harvest of aquatic resources to achieve optimum sustained yields. Pollution and habitat destruction shall be stringently opposed through the strict enforcement of all laws and administrative rules. Special regulations shall be used to provide diverse angling opportunities and to distribute use in heavily fished areas.(7) TROUT STREAM CLASSIFICATION. The department shall identify and classify trout streams as follows to ensure adequate protection and proper management of this unique resource. (a) For the purpose of this subsection, the following terms are defined as: 1. "Classification survey" means a fishery survey employing techniques generally accepted by fisheries biologists that:a. Investigates the variety of habitat types present in the water being surveyed;b. Provides a representative sample of the fish species present, and their relative abundance;c. Provides the length distribution and the age structure of the trout population.2. "Trout spawning habitat" means areas of gravel, small rubble or coarse sand which are infiltrated by groundwater or stream flow of sufficient quantity and quality to allow successful hatching of trout eggs and emergence of fry.3. "Trout habitat" means those areas having sufficient quantity and quality of water, cover and food to allow trout to complete one or more life history stages.(b) Classification of trout streams, as determined by classification surveys, shall be based on the following criteria: 1. 'Class I'. A class I trout stream is a stream or portion thereof with a self-sustaining population of trout. a. Such a stream contains trout spawning habitat and naturally produced fry, fingerling, and yearling in sufficient numbers to utilize the trout habitat, orb. Contains trout with 2 or more age groups, above the age of one year, and natural reproduction and survival of wild fish in sufficient numbers to utilize the available trout habitat and to sustain the fishery without stocking.2. 'Class II'. A class II trout stream is a stream or portion thereof that: a. Contains a population of trout made up of one or more age groups, above the age one year, in sufficient numbers to indicate substantial survival from one year to the next, andb. May or may not have natural reproduction of trout occurring; however, stocking is necessary to fully utilize the available trout habitat or to sustain the fishery.3. 'Class III'. A class III trout stream is a stream or portion thereof that: a. Requires the annual stocking of trout to provide a significant harvest, andb. Does not provide habitat suitable for the survival of trout throughout the year, or for natural reproduction of trout.(c) After classification or reclassification of a stream or portion thereof under this subsection, the department shall, as soon as is feasible or reasonable, give notice in a newspaper or such other media the department selects in the area affected which is likely to inform the local residents. The department shall provide the information to all clerks of the county, town, city or village in which the stream or portion thereof is located. The department shall notify the legislators whose districts include the affected stream and the chairpersons of the committees of the legislature with jurisdiction for natural resources issues.(d) The notice shall contain the location and description of the stream and the basis for its classification. If a hearing is not requested in writing within 30 days after the mailing of the notice, the department may waive the hearing. Upon receipt of a request for a hearing, the department shall, not less than 10 days before such hearing, mail written notice thereof to each person notified under par. (c).(e) At each hearing, the department shall take evidence offered by persons in support of or in opposition to the stream classification. If the department finds the stream is not properly classified, the stream shall be reclassified on the basis of the criteria specified under par. (b).(f) The department shall maintain a list of classified trout streams for public information. This list shall not be assumed to be exhaustive but will include all trout streams surveyed and classified.Wis. Admin. Code Department of Natural Resources NR 1.02
