Objectives of Cruise:
A primary objective of the cruise was to conduct bottom trawl sampling in Bering Canyon to collect ripe adult Greenland halibut (Reinharditus hippoglossides). Trawling was conducted with a Poly Nor’eastern Bottom Trawl (PNE) with mud sweep gear and V doors. Trawling (9 trawls) was done using 2 independent net monitoring systems, A Furuno CN-24 and a Scanmar. We were able to successfully execute all trawls, but unfortunately all spawning activity had been completed in Greenland halibut. All females were spent in all trawls, though running males were observed during the first few days of the trawl survey. Running males were held in a flow-through live tank staged on the back deck. After the first 3 or 4 days however, it was observed that males collected from trawls were spent out as well. Efforts were made to conduct trawling further north, in the event that spawning occurs somewhat later in a more northerly geographic area, but it was found that all Greenland halibut from collected from Pribilof Canyon were also past spawning. Spawning in this species, at least in Bering and Pribilof Canyons, probably occurs earlier than the departure date for this cruise. Delays in the ship’s departure from Seattle due to repair needs at the end of the winter import may have impacted the success of this cruise. We were not successful in meeting our primary objective of collecting spawning condition male and female Greenland halibut, or of obtaining fertilized eggs from strip-spawning activities for use in on-board experiments or for rearing at the AFSC in Seattle, WA.
A secondary objective was to conduct an ichthyoplankton survey in the Bering/Pribilof Canyon area. Bongo tows (30 stations) were successfully completed that were used to describe the distribution of Greenland halibut eggs over the slope and in Bering and Pribilof Canyons in winter. Limited numbers of field-collected eggs were used for on board buoyancy experiments in the Controlled Environment Room. Temperature and salinity data were successfully collected from Seacat mounted on all bongo tows. Note: The FOCI seacat was used for the second half of the cruise due to a malfunction on the ship’s unit.
Atheresthes spp. larvae that were collected from 60Bon net 2 were preserved for molecular identification at sea. Molecular identifications were successful, and 1 arrowtooth flounder (Atheresthes stomias) larva and 5 Kamchatka flounder (Atheresthes evermanni) larvae were identified from collections.
Data on physical characteristics of the water column were also successfully collected. We deployed 2 oceanographic instrumentation moorings, one in Bering Canyon (75 kHz, 400 m depth) and one on the EBS shelf (300 kHz, 125 m depth) in the vicinity to Unimak Island. We used the SIMRAD EK 60 Scientific Echosounder Monitoring system to collect ancillary data on adult fish aggregations during the entire cruise.

Summary of Cruise:
Trawling: Trawling was conducted with a Poly Nor’eastern Bottom Trawl (PNE) with 1000 kg V-doors. We were able to successfully execute all trawls. Adults male and female Greenland halibut were collcted from most tows (600-900 m depth) but all individuals were in post-spawning condition.
Ichthyoplankton Sampling: Ichthyoplankton sampling was conducted using a 20cm/60cm Bongo net array. Sampling for eggs and larvae occurred at approximately 30 stations in the Bering/Pribilof Canyon vicinity. Sampling was conducted to localize areas of high egg density. Higher egg densities would indicate areas of spawning which would be appropriate for bottom trawling.
Ichthyoplankton vertical sampling:
The MOCNESS array was set up and staged in the deck awaiting operation. The weather during the cruise was very poor, and it was not deemed safe to deploy the gear at any time. Depth-discrete measurements were not collected on this cruise
Mooring Deployment: A 300 kHz oceanographic mooring equipped with a microcat and ADCP was deployed at 115 m depth at 55o02.83”N165o05.67” W. This location is probably slightly deep, but should provide most water column information necessary. These coordinates were in error on the cruise instructions. A 75kHz oceanographic mooring equipped with a microcat and ADCP was deployed at 400 m depth at 54o35.86”N166o33.65”W. For the bongo tow, the 60BON was fitted with 505m mesh on both sides. The sample from 60BON Net 2 was sorted for Greenland turbot, arrowtooth flounder, Pacific halibut, and myctophidae. Species of interest were preserved in 70% EtOH and the remainder of the sample was discarded. Some euphausiids collected from 60BON net 2 were frozen as part of a winter bird diet study (FWS). The 20BON array was fitted with 153m mesh on both sides. The SeaCat profiler was attached in line during all bongo tows. CTD casts were conducted at selected stations. MOCNESS sampling occurred at 3 stations.

Weather: 48 hrs
