SACRAMENTO – Updated fish advisories issued today for Castaic Lake and Castaic Lagoon in Los Angeles County add safe-eating advice for several species.

Castaic Lake and Castaic Lagoon are located approximately 10 miles north of Santa Clarita, in Los Angeles County. The advisory for Castaic Lake provides safe-eating advice for black bass species, Channel Catfish, Common Carp, silverside species, Striped Bass, sunfish species and Threadfin Shad. The advisory for Castaic Lagoon provides safe-eating advice for black bass species, Common Carp, sculpin, silverside species, sunfish species and Threadfin Shad.

The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) developed the recommendations based on the levels of mercury and polychlorinated biphenyls (PCBs) found in fish caught from the lakes.

“Many fish have nutrients that may reduce the risk of heart disease and are excellent sources of protein,” said OEHHA Director Dr. Lauren Zeise. “By following our guidelines for fish caught in Castaic Lake and Castaic Lagoon, people can safely eat fish low in chemical contaminants and enjoy the well-known health benefits of fish consumption.”

When consuming fish from these lakes, the following advice is issued:

  • Castaic Lake
    • Women ages 18 – 49 and children ages 1 – 17 should not eat black bass species or Channel Catfish. They may safely eat a maximum of seven total servings per week of silverside species; or three total servings per week of sunfish species; or two total servings per week of Threadfin Shad; or one total serving per week of Common Carp or Striped Bass.
    • Women ages 50 and older and men ages 18 and older may safely eat a maximum of seven total servings per week of silverside species or Threadfin Shad; or four total servings per week of Common Carp or Striped Bass; or three total servings per week of sunfish species; or one total serving per week of black bass species or Channel Catfish.
  • Castaic Lagoon
    • Women ages 18 – 49 and children ages 1 – 17 may safely eat a maximum of seven total servings per week of sculpin, silverside species, sunfish species or Threadfin Shad; or two total servings per week of Common Carp; or one total serving per week of black bass species.
    • Women ages 50 and older and men ages 18 and older may safely eat a maximum of seven total servings per week of sculpin, silverside species, sunfish species or Threadfin Shad; or two total servings per week of black bass species or Common Carp.

One serving is an eight-ounce fish fillet, measured prior to cooking, which is roughly the size and thickness of your hand. Children should eat smaller servings. For small fish species, several individual fish may make up a single serving.

Posters with the safe-eating advice for Castaic Lake and Castaic Lagoon are available on OEHHA’s website in both English and Spanish. For fish species found in Castaic Lake and Castaic Lagoon that are not included in this advisory, OEHHA recommends following the statewide advisory for eating fish from California lakes and reservoirs without site-specific advice.

Mercury is released into the environment from mining and burning coal. It accumulates in fish in the form of methylmercury, which can damage the brain and nervous system, especially in developing children and fetuses. Because of this, OEHHA provides a separate set of recommendations specifically for children up to age 17 and women of childbearing age (18 – 49 years).

PCBs are a group of industrial chemicals. At high levels of exposure, they can cause health problems, including cancer. Although they were banned in the United States in the late 1970s, PCBs persist in the environment from spills, leaks or improper disposal. PCBs accumulate in the skin, fat and some internal organs of fish. To reduce exposure from PCB-contaminated fish, OEHHA recommends eating only the skinless fillet (meat) portion of the fish.

OEHHA’s fish advisory recommendations are based on the levels of contaminants, such as mercury and PCBs, that persist in the environment and accumulate in fish. They are independent of any advisories to limit fish intake due to freshwater or estuarine harmful algal blooms (HABs). Before fishing, check the California HABs Portal to see if there are recommended HAB advisories and always practice healthy water habits.

Eating fish in amounts slightly greater than the advisory’s recommendations is not likely to cause health problems if it is done occasionally, such as eating fish caught during an annual vacation.

The Castaic Lake and Castaic Lagoon advisories join more than 130 other OEHHA advisories that provide site-specific, health-based fish consumption advice for many of the places where people catch and eat fish in California, including lakes, rivers, bays, reservoirs and the California coast. Advisories are available on OEHHA’s Fish Advisories webpage.

OEHHA’s mission is to protect and enhance the health of Californians and the environment through scientific evaluations that inform, support, and guide regulatory and other actions in the state.
