2016 California Current Ecosystem (CCE 16): Investigations of hake survey methods, life history, and associated ecosystem (SH1610, EK80)

SH 16-10

1. Use paired midwater trawls to evaluate potential selectivity of Pacific hake age/size classes by different codend liners (Standard AWT 32 mm versus 7 mm used by DFO on their Cantrawl) in the Aleutian wing trawl 24/20 (AWT). Midwater trawling for this research will take place on all three survey legs.
2. Use paired trawls to evaluate performance of net with and without the marine mammal excluder installed.
3. Test a larger kite on the AWT for stability and ease of use with headrope sensors.
4. Continuously sample multi-frequency acoustic backscatter data using the ship?s Simrad EK60, EK80, and ME70 scientific echo sounder systems to estimate the distributions and abundances of hake, myctophids, gelatinous zooplankton, and krill.
5. Conduct research using the EK80 to distinguish between hake, myctophids, and rockfish. Compare EK80 backscatter signature with that of the EK60.
6. Optically observe fish behavior inside daytime trawls using a video or stereo camera and lights mounted inside the net. Test stereo camera system for quantifying fish species and length.
7. Collect a variety of other acoustic, biological, and oceanographic samples to characterize the biotic and abiotic environments and predator-prey interactions of the surveyed species.
8. Investigate near-field calibration techniques.
9. Use night operations time to conduct hydrographic measurements with a CTD. A NWFSC dissolved O2 sensor will also be mounted on the CTD.
10. Sample profiles of temperature and salinity using an underway conductivitytemperature-depth (CTD) system during daytime operations.
11. Continuously sample air temperature, barometric pressure, and wind speed and direction using the ship?s integrated weather station.
