Lower Willamette Fish Advisory

FactsheetA news release describing the Lower Willamette fish advisory was issued on April 11, 2018, to alert the public about which fish to eat and which fish to avoid or to be careful about eating. While it’s important for people to know about contaminants in fish and shellfish to protect themselves and their families, it is equally important for everyone to eat a variety of fish from a variety of sources to gain important health benefits.

The Portland Harbor fish advisory issued by the Oregon Health Authority (OHA) in 2004 has been updated. The update is a result of more recent data made available to OHA, and includes updated meal recommendations and an expansion of the advisory boundary. The summary factsheet, which explains the advisory, has been translated into several languages, and a list of frequently asked questions is provided below.

Resident Fish Consumption

Recommended maximum meals per month for resident fish:
black crappie 2 meals
Black Crappie - 2 meals per month (or 4 meals if fillet only)

Shellfish Consumption

Recommended maximum meals per month for shellfish:

crayfish 2 meals
Crayfish - 2 meals per month

mussels 7 meals

All other resident fish, such as walleye, should not be eaten. Resident fish live in the river their entire life and over time can accumulate levels of contaminants that are unhealthy. OHA recommends eating migratory fish like salmon, steelhead, shad and trout that spend most of their lives in the ocean, or in other tributaries connected to the Lower Willamette. This fish advisory does not include migratory fish.
