High PSP Levels Close Southeast Alaska Geoduck Clam Fishery

By | January 9, 2014

Southeast Alaska’s geoduck clam dive fishery did not open this week because high levels of Paralytic Shellfish Poisoning were found.

Clams from eight fishing areas were sampled, and Fish and Game assistant Management Biologist Justin Brease says they all turned up positive.

“Looks like they tested eight areas for a potential opening, and all of those areas failed the PSP test, so therefore we didn’t have any areas left that we could open, so we didn’t have any openings for geoducks this week,” Brease said.

Brease says PSP testing frequently finds positive test results in the Southeast clams.  Often several areas will test positive. This time, all of them did.

“It isn’t necessarily all that unusual that they have positive results at all. In fact it’s not uncommon for there to be high results everywhere,” Brease said. “We’re kind of at the northern end of the range for geoduck clams and we typically have higher PSP levels than, say, down in Washington.”

The Southeast Alaska Region Dive Fisheries Association will go out and take more samples this weekend for a potential opening on Jan. 16.

The geoduck clam market is depressed right now because its biggest customer is China, which barred imports of West Coast geoducks last month claiming bad PSP and arsenic results that both Alaska and Washington State authorities said they had found no sign of.

Still, Washington closed a fishery area just in case and this week Alaska is unable to open any areas.
