April 11, 2017 — Fishing for Pacific sardines in California has been banned for the third year in a row.
The Pacific Fishery Management Council voted Monday afternoon in Sacramento to close the fishery through June 30, 2018 because the population limit of 150,000 metric tons wasn’t met.
Researchers estimate that only about 87,000 metric tons of the oil-rich fish are now swimming around off the coast.
The decision blocks commercial fishers in San Pedro, Long Beach and elsewhere across the West Coast from anything other than small numbers of incidental takes. While sardines don’t command the high price of California shellfish, their plentiful numbers and popularity make them one of the state’s most-caught finfish.
But fishery managers say there’s reason to believe sardines are much more plentiful than studies have found.
Flawed Count?
NOAA’s Southwest Fisheries Science Center deputy director Dale Sweetnam said the acoustic-trawl method that researchers use to estimate the number of sardines is in the process of being improved to take into account other areas closer to shore.
The count is done from a large NOAA ship that surveys the entire West Coast by sampling schools of fish, and then bounces sound waves off of them to create a diagram that estimates the size.
But the ship is too large to go into harbors or coastal areas where sardines like to congregate.
“There are questions about the acoustic detector being on the bottom of the ship — how much of the schools in the upper water columns are missed by the acoustics,” Sweetnam said. “Also, the large NOAA ship can’t go in shallow waters, but most of the sardine fishery is very close to shore.”
The fisheries service will soon employ a Department of Fish and Wildlife plane, along with drones, to survey coastal areas for sardines.
