2.0. OPERATIONS
A standard oceanographic watch will be utilized which consists of a
winch operator, a scientific staff of three and a Survey Tech on deck.
Operations will be conducted 24 hours a day.
2.1. SUMMARY OF ACTIVITIES:
Line 8 time-series observations: Biological oceanographic observations
will be taken at 8 stations along FOCI Line 8 in Shelikof Strait.
El Nino stations:
Live Tucker trawl tows for pollock eggs: One or more Tucker trawl tows,
with one net fishing near bottom (180-200 m), and the other from that depth
to the surface will be conducted in Shelikof Strait and over the shelf
in the Bering Sea to obtain live pollock eggs to bring back to Seattle
for experimental work at AFSC. Taped codends will be used to minimize trauma
to the eggs during collection. At the conclusion of the tows, the nets
will be gently washed and live eggs will be sorted from them immediately.
Those from the at-depth net will be placed in rearing refrigerators. At
the end of the cruise these live eggs will be packed in insulated bottles
for air transport to Seattle. Some eggs from the depth-to-surface net will
be fixed in ethanol for genetic analysis in Seattle, others will be brought
back to Seattle live for experimental work.
Pollock egg vertical distribution: A bongo survey of 24 stations will
be conducted over the shelf of the southeastern Bering Sea to map pollock
egg distribution and locate areas of high concentrations. Within the area
of the survey, two locations will be selected for vertical distribution
tows with a Tucker trawl. At each of these selected locations, first, live
Tucker tows will be made near surface (0-20 m) and near bottom (ca. 80-100
m) to obtain live eggs to retunr to Seattle for specific gravity experiments.
Then replicate series of Tucker trawls at 20 m depth intervals, from surface
to bottom, will be performed and the samples preserved for analysis ashore.
Pollock egg incubations, genetic samples: The ship will locate aggregations
of walleye pollock in both Shelikof Strait and over the shelf of the southeastern
Bering Sea, using information obtained from the preceding RACE hydroacoustic
cruise, and reports from the fishing fleet. Ship and scientific personnel
will monitor the EQ-500 echosounder to identify these aggregations. When
walleye pollock are located, a midwater trawl will be deployed. Ripe walleye
pollock caught in the trawls will be stripped and the eggs will be incubated
in four refrigerators located in the fish processing lab. Fin clip samples,
and tissue samples for genetic analysis will also be obtained from trawled
pollock (sample 100-120 fish from each haul). Live eggs (~16,000) will
be brought back to Seattle for experimental work at AFSC. Once sufficient
eggs are obtained for the experiments, the ship will break off these operations.
AFSC scientific personnel will sample the eggs throughout the incubation
period (~60 days), including on subsequent cruises, and perform daily maintenance
on the incubators (i.e., change water, remove dead eggs).
Diel patten of pollock spawning:
Middle Shelf Domain monitoring observations: Biological oceanographic
observations will be taken at 7 stations over the shelf in the southeast
Bering Sea.
Pribilof Canyon pollock egg survey: A grid of 20 stations in the vicinity
of Pribilof Canyon will be sampled using standard MARMAP bongo tows to
a maximum depth of 400 m, as water depth permits. Samples will be preserved
for analysis ashore.
2.2 PROCEDURES FOR OPERATIONS:
The following are operations to be conducted on this cruise. The procedures
for these operations are listed in the FOCI Standard Operating Instructions
(SOI). Operations not addressed in the SOI and changes to standard procedures
are addressed below.
CTD/Water samples (SOI 2.2.1)
MARMAP bongo tow (SOI 2.2.2): Both Line 8 and standard 60 cm bongo tows
will be taken. 0.333 and 0.505 mm mesh nets will be used for the standard
bongo tows.
Live Tucker trawl tows (SOI 2.2.3): Live tows will be taken for pollock
eggs using 0.505 mm mesh nets, and taped codends. Depths of tows may vary
from those in SOI. After gentle rinsing, both codends will be sorted for
pollock eggs immediately following retrieval.
Midwater trawl (SOI 2.2.8): Trawling for spawning adult pollock will
be conducted in both Shelikof Strait and the Bering Sea using whichever
trawl is deemed most suitable. Midwater trawls will be deployed using standard
procedures for the gear requested. The Chief Scientist or watch chief will
decide trawl locations, times and depths. Midwater trawls will be conducted
day or night and will depend on plankton catches or midwater sign seen
on the EQ-50 echosounder. Once a trawl is called for, regardless of the
time of day, the fishing crew will need to be activated quickly, with little
time lost. Trawl time should be of short duration; only long enough to
descend into the school, fish for 10-15 minutes, then be brought up. The
trawl should be landed as quickly as possible and emptied into the sorting
table on deck. Scientific personnel will quickly sort through the catch
and put suitable fish into filled sinks in the wet and/or fish processing
labs. Should it be necessary to obtain more ripe fish at the same location,
the trawl should be readied and re-deployed as quickly as possible.
Tucker trawl (SOI 2.2.9): 0.505 mm mesh nets will be used. Sampling
depth intervals will be 0 20, 20-40, 40-60, 60-80, and 80-100 m, as water
depth permits.
