California Current Fish Surveys Resume with 3-Month Assessment of Sardine, Anchovy, and Mackerel

July 22, 2021 — The following was released by NOAA Fisheries:

NOAA Fisheries has begun an ambitious assessment of small pelagic fish reaching from the Canadian border to the southern tip of the Baja Peninsula, in cooperation with Mexico, which will help determine how many fish can be caught off the West Coast.

The COVID-19 pandemic had idled surveys for sardine, anchovy, and other species of small coastal pelagic species (CPS) off the West Coast since 2019. Small pelagic species are important ecologically and provide food for larger fish, such as tunas. The new assessment resumes regular CPS  surveys by collecting data from NOAA Ship Reuben Lasker, commercial fishing vessels equipped with acoustic technology, and autonomous Saildrones.

The Lasker left San Diego on July 6, becoming the centerpiece of the 3-month survey. It will cover thousands of miles in U.S., and Mexican waters. NOAA Fisheries scientists are coordinating efforts with federal fisheries agencies in Mexico and Canada, providing a science foundation for future decisions on fishing levels and seasons.

“Organizing and coordinating this survey was a tremendous feat of collaboration,” said Kristen Koch, Director of the Southwest Fisheries Science Center in La Jolla, which is leading the survey. “Collecting data across all three countries will provide a valuable foundation for management of these important transboundary species.”

The Lasker will survey coastal pelagic fish along transects in the California Current, quantifying the fish with echosounders. These instruments include an advanced new model that can for the first time also measure the velocities of fish as they swim relative to the ship. The measurements will help to understand whether and how fish respond to survey vessels and if those reactions affect the quality of data on the numbers and distributions of fish.

Pelagic survey highlights NOAA’s growing collaborative relationship with industry

August 30, 2017 — Earlier this year, officials with the National Oceanic and Atmospheric Administration used the Lisa Marie, a private fishing boat, to collect data for its annual coastal pelagic species survey. The move was part of an effort to increase collaboration between the public and private sectors.

Earlier this summer as officials with the U.S. National Oceanic and Atmospheric Administration completed work on an annual survey of coastal pelagic species (CPS) in the Pacific Ocean, they received some assistance from a new source: the private sector.

Not only were representatives from the West Coast seafood trade industry on board a federal vessel for five days while survey samples were taken, but one fisherman allowed NOAA officials to outfit his boat with equipment to survey more shallow waters near the coastline. The collaborative venture marked a milestone in a public-private dialogue that’s been going on for years.

The CPS survey collects data primarily on Pacific sardines, said Kristen Koch, the acting science and research director of NOAA’s Southwest Fisheries Service Center in La Jolla, California, but it also includes observations on other CPS fish such as northern anchovy and jack and Pacific mackerels. Typically, officials use the Reuben Lasker, a NOAA vessel, to conduct the survey. However, private sector representatives felt the government was missing out on some key data in their work.

Government leaders welcomed the idea to get more data to fill in the gaps they also sought to fill.

“Data is like gold to us,” said Koch. “If we can collect more of the kind of data we need, it improves the precision of our assessments of these species.”

Fishermen See ‘Science in Action’ Aboard NOAA Survey Ship

August 18, 2017 — Each spring and early summer, scientists set out along the West Coast aboard NOAA vessel Reuben Lasker to survey coastal pelagic species, or CPS, which includes small schooling fish such as northern anchovy, Pacific sardine, and jack and Pacific mackerels.

This year, with the help of West Coast fishermen, the scientists tested a new approach to extend their reach into nearshore waters to improve the accuracy of the survey results. The collaboration involved the fishing vessel Lisa Marie, of Gig Harbor, Washington, and brought two commercial fishermen aboard Lasker for an inside look at NOAA Fisheries surveys that inform stock assessments and guide decisions on how many fish can be caught by West Coast fishermen.

The idea emerged years before when the then-Director of NOAA’s Southwest Fisheries Science Center in La Jolla, California,  Cisco Werner, along with Deputy Director Kristen Koch and Fisheries Resources Division Director Gerard DiNardo, discussed the potential collaboration with Mike Okoniewski of Pacific Seafood and Diane Pleschner-Steele of the California Wetfish Producers Association.

Werner has since been named Chief Scientist of NOAA Fisheries.

The Magnuson-Stevens Fishery Conservation and Management Act requires NOAA Fisheries to use the best available science to help managers set catch limits and prevent overfishing. Annual surveys, using echosounders to detect and measure the abundances of CPS populations off the coasts of California, Oregon, Washington, and Canada’s Vancouver Island help fulfill this mandate. NOAA Fisheries also uses trawl catches, and fish-egg samples to help gauge fish reproduction and population trends.

“Acoustic-trawl surveys are our principal tool for monitoring the various species and determining how their abundances, distributions, and sizes are changing,” said David Demer, the Chief Scientist of the survey and leader of the Advanced Survey Technologies Group at Southwest Fisheries Science Center in La Jolla. “The surveys are very rigorous because they’re very important to our mission.”
