Most tows were targeted for coastal pelagic species (e.g., sardine, anchovy, mackerels) using a Nordic trawl (2023 and before) or a Multi-Function Trawl net (2024 and after) on the surface at night. The database includes information on individual trawls, catch data with identification to various taxonomic levels depending on species, length frequencies, and individual length and weight data. The trawls serve to estimate the species composition and demographics of the fishes sampled acoustically during the day. These data are used to estimate the abundance of Pacific sardine, Jack mackerel, Pacific mackerel, Northern anchovy, and Pacific herring in the California Current. underDevelopment Erisman, Brad (619) 792-6100 8901 La Jolla Shores Dr. La Jolla CA 92037 United States brad.erisman@noaa.gov custodian annually ATM theme Acoustic Trawl Method DEPM theme daily egg production method anchovy platform Engraulis mordax sardine platform Sardinops sagax Pacific mackerel platform Scomber japonicus jack mackerel platform Trachurus symmetricus DOC/NOAA/NMFS/SWFSC > Southwest Fisheries Science Center, National Marine Fisheries Service, NOAA.

Midwater Rope Trawl Trawl Nets Employs a four-seam box design with a 174 feet headrope, footrope, and breastlines. The mouth opening of the HSMRT is approximately 13.3 meters vertical and 27.5 meters horizontal. Once the net is deployed, changes in the position of the net in the water column are made by increasing or decreasing the speed of the vessel, or by bringing in or letting out trawl wire. Nordic 264 Rope Trawl Trawl Net The trawl mesh is constructed of nylon cord and has an overall length of 93.45 meters plus an additional 8.5 meters for the sampling codend, which has a liner with a mesh size of 8 millimeters sewn in. The working mouth opening has been measured as 600 m² at a towing speed of 3.5 knots.The rigging for the Nordic 264 rope trawl is comprised of an upper and lower leg per side each 70 meters in length. When connected to the door legs, the entire bridle is almost 80 meters in length. The lower bridle has an additional chain set-back to optimize the efficiency of the trawl in regards to the projected towing depth. Removable clump weights of 91 kilograms are connected at the forward section of the set-back chain by means of a G-hook/flat-link connection, in order to maximize vertical spread of the trawl. The trawl doors are 3.0 square meters in area and have a dry weight of 523 kilograms (1,150 lbs.). These hollow doors are filled with a non-compressible syntactic foam which gives them a weight in water of 135 kg. Bell M. Shimada (SH) The fourth vessel of its kind, Bell M. Shimada offers fisheries scientists the ability to monitor fish populations without altering their behavior, allowing them to collect data with unprecedented accuracy. With better data, biologists and oceanographers can help managers make better management decisions. In the Pacific, Bell M. Shimada will help scientists gain valuable insight into the California Current Large Marine Ecosystem, a globally significant natural resource that stretches from Baja California to British Columbia. Two scientists at the Center recently described some of the way in which this vessel will enhance existing or open opportunities for new research projects.

Miller Freeman (MF) The Miller Freeman was decommissioned on 3/29/13 after many years of exemplary service. Pictures of the ceremony will be posted here when available - please check back soon. Miller Freeman was a 215-foot fisheries and oceanographic research vessel and was one of the largest research trawlers in the United States. Miller Freeman's primary mission was to provide a working platform for the study of the ocean's living resources. The ship was named for Miller Freeman (1875-1955), a publisher who was actively involved in the international management of fish harvests. The ship was launched in 1967, but not fully rigged until 1975. The vessel was again re-rigged in 1982. Miller Freeman was homeported at the Marine Operations Center-Pacific in Newport, Oregon. With a 12,578 mile / 31 day endurance, Miller Freeman was capable of operating in any waters of the world. Miller Freeman was owned by the United States of America, Department of Commerce's National Oceanic and Atmospheric Administration. The ship was operated by NOAA Marine and Aviation Operations and carried a complement of 7 NOAA Corps officers, 27 crew members, and maximum of 11 scientists.

Reuben Lasker (RL) Funded under the American Recovery and Reinvestment Act and built by Marinette Marine Corporation in Wisconsin, the ship's primary objective is to support fish, marine mammal, and turtle surveys off the U.S. West Coast and in the eastern tropical Pacific Ocean. The ship has a low sound signature to reduce reactions of fish to the presence of the ship and provides for a low signal-to-noise ratio for acoustic sensors. This allows scientists to study fish populations and collect oceanographic data with fewer effects on fish and marine mammal behavior. The multi-frequency scientific sonars provide the ability to conduct acoustic surveys that can distinguish fish types, estimate biomass, determine fish school shapes, and provide data on sea floor topography. Reuben Lasker is also equipped with oceanographic sampling and measurement systems, instrumented trawls, longlines, and plankton nets for direct sampling. The ship has a dynamic positioning system to steer along a pre-determined trackline and to accurately hold the ship in a fixed position. The ship is also equipped with meteorological data collection systems and has extensive wet and dry labs to provide maximum utilization of every hour at sea. These technologies will dramatically improve the ability to conduct diverse data collection operations as required by its mission. The ship is named after Dr. Reuben Lasker (1929-1988), who served as the Director of SWFSC's Coastal Fisheries Division and as adjunct professor at Scripps Institution of Oceanography, U.C. San Diego. Dr. Lasker built a renowned research group that focused on the recruitment of young fish to the adult population - a topic with implications for fisheries management throughout the world.

David Starr Jordan The David Starr Jordan was designed and built for the U.S. Bureau of Commercial Fisheries, which later became part of the National Oceanic and Atmospheric Administration, for the purpose of fisheries research in the tropical Pacific. The David Starr Jordan logged over a million miles while studying the biological and physical oceanography of the southwestern U.S. coast and the eastern tropical Pacific. David Starr Jordan was an integral part of the marine mammal surveys conducted by the Protected Resources Division of the NOAA National Marine Fisheries Service's Southwest Fisheries Science Center until her decommissioning on August 3rd, 2010.

Oscar Dyson (DY) the Oscar Dyson supports NOAA's mission to protect, restore and manage the use of living marine, coastal, and ocean resources through ecosystem-based management. Its primary objective is as a support platform to study and monitor Alaskan pollock and other fisheries, as well as oceanography in the Bering Sea and Gulf of Alaska. The ship also observes weather, sea state, and other environmental conditions, conducts habitat assessments, and surveys marine mammal and marine bird populations.
