2013 Joint U.S.-Canada Integrated Acoustic and Trawl Survey of Pacific Hake and Pacific Sardine (SaKe 2015) (SH1507, ME70)
The 2015 SaKe survey will span the west coasts of the U.S. and Canada from approximately lat 32.8°N (San Diego) to approximately lat 54.65°N (Dixon Entrance, Canada). Eastern and western extents will primarily range from the 20-m isobath or as close to shore as is safely navigable, to either the 1,500-m isobath or a point 35 nmi west of the inshore waypoint, whichever is farther offshore. The primary goal of the survey is to estimate the biomasses, distributions, and biological compositions of populations of Pacific hake and CPS using data from an integrated acoustic and trawl survey off the west coasts of the U.S. and Canada from approximately San Diego, California (lat 32°48.02’N) to the Dixon Entrance, Canada (lat 54°39.00’N). Besides Pacific sardine, the other CPS of interest for the SWFSC are those comprised in the Pacific Fisheries Management Council Fisheries Management Plan (PFMC, 2011) including: Northern anchovy (Engraulis mordax), Pacific Mackerel (Scomber japonicus), Jack Mackerel (Trachurus symmetricus). The NWFSC and SWFSC are interested in all species of euphausiids found within the U.S.’ West Coast EEZ. The current sampling resolution will probably not allow for a comprehensive assessment of all anchovy sub-populations. In particular, those residing in the Southern California Bight and off the Columbia River plume might require additional effort given their patchy distribution. SaKe 2015 will continue to monitor the populations of Ecosystem Component Species (ECS; PFMC, 2011), in particular Pacific Herring (Clupea pallasii). Continuously sample multi-frequency acoustic backscatter data using the ship’s Simrad EK60 scientific echosounder system. These data will be used to estimate the distributions and abundances of hake and the CPS assemblage. Conduct daytime trawling to classify observed backscatter layers to species and size composition and to collect specimens of hake and other organisms. Conduct nighttime (i.e., between sunset and sunrise) surface trawling to collect specimens of coastal pelagic fishes (CPS) and other organisms. These data will be used to classify CPS backscatter to species and their size distributions. Nighttime sampling operations will conclude in time for the ship to resume running east-west acoustic transects by sunrise. Image fish using a portable X-radiograph machine for the purpose of target strength modeling and estimation. Collect a variety of other acoustic, biological, and oceanographic samples relevant to hake and CPS distributions. These data are vital for the surveys and assessments of hake and CPS. Continuously sample sea-surface temperature, salinity, and chlorophyll-a using the ship’s thermosalinograph and fluorometer. These data will be used to estimate the physical oceanographic habitats for each target species. Continuously sample air temperature, barometric pressure, and wind speed and direction using the ship’s integrated weather station. Continuously sample pelagic fish eggs using the Continuous Underway Fish Egg Sampler (CUFES). The data will be used to estimate the distributions and abundances of spawning hake, and multiple CPS. Sample profiles of temperature and salinity using a combination of an underway conductivity-temperature-depth (CTD) system during the day or a standard CTD system with water-sampling rosette and other instruments at nighttime stations, as time allows. Sample plankton using a Vertical Ring Net net at nighttime stations, as time allows. These data will be used to estimate the distribution and abundance of ichthyoplankton and zooplankton species. Continuously sample multi-frequency acoustic backscatter data using the ship’s Simrad ME70 multibeam echosounder system, synchronized and configured to not interfere with the EK60s. Optically verify CPS backscatter while underway conducting acoustic transects, using a cast stereo camera system.Optically observe fish behavior inside nighttime trawls using cameras and lights mounted inside the net.

Purpose | The 2015 joint U.S.-Canada integrated acoustic and trawl survey of Pacific hake (Merluccius productus), Pacific sardine (Sardinops sagax) and Coastal Pelagic Fishes (CPS), hereafter 2015 SaKe survey, assesses the biomasses, distributions, and biological compositions of hake, sardine, and other Coastal Pelagic Species (CPS) populations in U.S. and Canadian waters off the Pacific coast. Scientists from Pacific Biological Lab of DFO, Canada on board the Canadian Coast Guard Ship (CCGS) W. E. Ricker also jointly participated in the Pacific hake survey. However, only data collected on board the US Ship FSV Bell Shimada are included in this package. |
