Answer: California Fish and Game Code (FGC) section 7145(a) requires that “every person 16 years of age or older who takes any fish, reptile, or amphibian for any purpose other than profit shall first obtain a valid license for that purpose.” One of CDFW’s primary roles is to manage California’s fish and wildlife resources for use by the public. Saltwater fishing license fees help support law enforcement and scientific research and management of marine resources. In addition, CDFW does operate some hatchery and stocking programs for marine fish, such as ocean salmon and white seabass.
