Species tables for Utah's fish, mollusks and crustaceans

Learn more about possession limits, prohibited species and mandatory reporting.

Utah has the following classifications for the collection and possession of fish, mollusks and crustaceans:

• Prohibited — Utah's prohibited species include aquatic animals that are classified as threatened or endangered under the Endangered Species Act as well as species that have been documented to cause ecological or economic harm within the United States. Prohibited species cannot be collected or possessed in any number without a variance (exception) obtained from the Utah Wildlife Board. Then, a certificate of registration must be issued by the DWR before any prohibited species can be collected or possessed.
• Controlled — Controlled species are animals whose illegal release could impact native fish, mollusk or crustacean populations, or damage valuable sportfish populations.

• Noncontrolled — Noncontrolled species are those that have either:

  • Low probability of survival if they are illegally introduced in Utah.
  • Minimal impact on other species if they are released.

  Noncontrolled species are widely available at pet shops. Most (but not all) ornamental fish, mollusks and crustaceans are classified as noncontrolled. Piranhas, red-bellied pacu and tilapia are sometimes illegally sold at pet stores, and the possession of these species is prohibited.

  Noncontrolled species can be purchased from in-state vendors without a COR from the DWR. However, an import permit from the Utah Department of Agriculture and Food is required if any species (including noncontrolled species) are imported into Utah from another state.

Important: Once you remove any fish, mollusk, or crustacean from the wild — whether it's non-native or native — it may not be released back into the wild.

Prohibited species (possession limit is zero)

The following species are classified as prohibited for any collection and possession, which means you may not collect them from the wild and keep them unless you have special approval (called a variance) from the Utah Wildlife Board:
