Abstract

Fish captured in trawls by the SWFSC Fisheries Resources Division during surveys for coastal pelagic species. Most tows were targeted for sardine using a Nordic trawl on the surface at night. The database includes identification to various taxonomic levels depending on species, length frequencies, biomass data, and some age data for sardine based on analysis of otoliths.

Abstract:

Fish captured in trawls by the SWFSC Fisheries Resources Division during surveys for coastal pelagic species. Most tows were targeted for sardine using a Nordic trawl on the surface at night. The database includes identification to various taxonomic levels depending on species, length frequencies, biomass data, and some age data for sardine based on analysis of otoliths.

Purpose:

These data have been collected primarily for use in the Pacific sardine stock assessment to estimate adult parameters for the daily egg-production method, and to quantify species compositions for acoustic estimates.

Lineage

Lineage Statement:

Fish are collected by Nordic surface trawls at sea where they are enumerated and a subset is weighed and measured. Additional data such as age and fecundity in the "specimens" table are collected in the laboratory from fish samples.

Instruments

Instrument 1

CC ID: 865315
Identifier: Midwater Rope Trawl
Instrument / Gear: Gear
Instrument Type: Trawl Nets
Description:

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.

Docucomp UUID: dfe238e9-703a-451c-af6b-29ba1b192468
Description:

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.

Description:

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.
