It may be , but it's also spooky season - so this week, let's focus on something a little spookier, courtesy of our Discover West Coast Seafood site (bit.ly/DWCS2026): sea urchins!
1. Species profile
Sea urchins are invertebrates that can live in subtidal kelp forests and rocky areas along the West Coast from Alaska to the southern end of Baja California. Three distinct species of sea urchins are commercially harvested: red, green and purple. They can grow up to seven inches in diameter and have spines varying from one to three inches long. Sea urchins are omnivorous and feed mainly on leafy seaweeds and algae. Illustration by Tom Crestodina, courtesy of Oregon Sea Grant.
2. Harvesters
Red sea urchin are harvested in Washington, Oregon, and California. Green sea urchins are harvested only in Washington. Purple sea urchins are harvested and cultivated (“ranched”) in Oregon and California. Get to know the people who harvest sea urchin along the West Coast.
3. Gear type profile
Sea urchins are typically harvested by divers who collect targeted species at depths less than 100 feet. Red and green urchins are most commonly dived for. Divers harvest urchins by hand, often using a specialised handheld rake, and place them in a large mesh bag. In ranching operations, purple urchins are harvested from the ocean and brought to tanks on land to finish growing. Illustration of Tom Crestodina, courtesy of Oregon Sea Grant.
4. Recipe
Sea urchins are harvested for their ‘roe’ (known as ‘uni’ in Japan), which is eaten fresh. But Japanese cuisine isn’t the only way to enjoy this West Coast delicacy. Any of the West Coast urchin species would be delicious in this Uni Bruschetta, perfect for your next fresh appetizer! Recipe adapted from Pacific Urchin Harvesters Association.
5. Availability
Sea urchins are typically sold as live or fresh products at local markets. Urchins are harvested and/or ranched in Washington from fall through early spring, and in Oregon and California year-round.
