Article 12. Crayfish of California Fish And Game Code >> Division 6. >> Part 3. >> Chapter 2. >> Article 12.

The taking of crayfish shall be subject to regulations as prescribed by the commission.
(a) Any allowance for the commercial taking of crayfish in Lake Tahoe or in the Lake Tahoe Basin shall be for the primary purpose of population reduction and control of the signal crayfish, an invasive species. The commercial taking of crayfish may be allowed only to the extent that it is consistent with state goals for management of invasive species and other environmental standards, including an environmental analysis conducted by the Tahoe Regional Planning Agency or another appropriate lead agency for each proposed individual harvest operation.
  (b) The commission shall ensure that, with respect to the taking of crayfish for commercial purposes in Lake Tahoe or in the Lake Tahoe Basin, the commission's regulations are consistent with the Lake Tahoe Region Aquatic Invasive Species Management Plan, as amended.
The department shall take the steps it determines are necessary to prevent overfishing of crayfish in the Sacramento-San Joaquin Delta. Those steps may include, but are not limited to, submitting to the Legislature proposed legislation to place limitations on the commercial crayfishing in that area.
