Netarts Bay Clam Loss

the best and most accessible clam beds in Netarts Bay o

However, no dredging had as yet been
Plane were immediately formulated for salvaging and transplanting clams

when dredging was to be conductedo
Unfortunately, the dredging operation was
conducted vith a 3-yard drag-line bucketo
This equipment broke the majority
of clams encountered and rendered salvage impracticalo
It was estimated that
20,000 clams were destroyed by this project and the bed completely removed from

Cockle Tagging
A preliminary study was started in 1961 io determine the feasibility of

This method was slowg tended to
shock the animals 9 and probabl1 accounted for veey high mortality rates in

The new methcd involved placing marine resin on the shell and
embedding a Petersen disc in the mate1-ial o T"Wenty-rour animals were tagged end
placed in the Depoe Bay Aquarium for a period of )0 dayso
period the clams were removed tor examinationo
and no ill effects vere notedo
At the end of this

The ones t hat bad failed to survive all showed
evidence of the resin having come in eon tact with the mantle edge o

Subsequently

RAZOR CLAMS
·Razor clam activities for this period continued much the same as in recent
years with most of the effort being extended to the. persoi.tal·=-use fishery o
Colllll8rcially dug clams . were sampled at Be 11 Buoy Crab Company in Seaside for
age composition and number of clams per poundo
Other activities were taking
plankton t ows, operating an experimental clam tank at the Seaside Aquarium»
screening for razor clam set, and preliminary experiments with a new clam
tagging techniqueo
Personal-Use Fishety
The 1961 sampling program was similar to that outlined in Progress Report
32 except that sampling was done on all minus=tide days from 1 hour before to
1 hour after lov water o
Sampling was discontinued at the Sunset road because
so few cars used the roado
Digging Intensity
The digging intensity for the April through September sampling period
increased over that of 1960 from 48 1 939 to 5lpll3 diggers and reflects the
occurrence of the low minus tides during the weekendso
Figure 1 shows the
sharp contrast between the high minus tides and the very low minus tideso
The
increased effort occurred at Seaside where 18,312 diggers in 1960 climbed t o
26i273 in 19flo
At the same time the north beach areas (between the Necanicum
River and the South Jetty of the Columbia Ri ve.t"') experienced a decrease

Seaside, for the first time since
catch b7 area bas been recorded, . produce.d more clams than the north beach wit h
3.52 9 887 as against 230,.399 clams for the north be_acho
The average catch per
digger was also higher at Seaside (13o7) as .opposed to 9o5 ·for the north beach
(Table 4 ) o.
The number of clams per pound gives an indication of the size of the clams
in the personal-use harvesto
The clams at Seaside ranged from 7o0 to 15ol per
pound, compared to 5o7 to llo4 per pound on

wastage was not measured i n 1961, but an average of the 1959 and 1960 wast=
age indicated that approximately 56,000 clams were wasted in 1961 or· 8% of the
total sport and commercial har1esto
Age Composition
Table 5 gives the number and percentage each age group contributed t o the
personal-use fishery in 1961o
A significant change is indicated by the sharp
rise in the catch of 0+ clams fram 51,000 in 1959 to 166,000 in 196lo
Past data
give good indication that a ·high take of 0+ clams one year follows through 'With
a high take of 1+ clams the next year o About 82% of the 1961 harvest were . clams
or age 0+ and 1+ 9 so an incoming year class will have a marked effect on the
fisher,y within 2 .yearso
The high take or 0+ clams as experienced in 1955=58 and 1961 represents
poor utilization of the resource, and this -c ondition exists in years following
a heavy set of clamso
The timing of this condition has, since 1955 9 occurred
during a period between July 15 and August )0..
clams of age 0+ were dug during this periodo
In 1961, for example 9 155 9 000
It may also be noted that wastage
is predominately 0+ clams and is most serious during this same 6,..veek period o
Commercial Fishery

Digging Intensity
An effort was made to determine the number of diggers who participated in
the 1961 commercial fisheryo
Licenses to harvest clams, scallops, and mussels
were issued to 24i~ persons,· 116 of whom were ~onsidered potential razor clam
diggerso
Seventy=three of these are lmown to have dug clams from Clatsop
beaches:) .32 local persons claimed no landings, and 11 are unknowno
Of the 73
known diggers, 42 sold clams at least once and 31 dug for personal useo
Only
12 of those who sold clams made 10 or more landingso
Harvest
The 1961 commercial harvest was the poorest on record as only 698 land=
ings were reported, totaling 21,218 pounds or approximately 90 »000 clams o
landings averaged 30o4 pounds which is the third highest since 1955o
