Fish
Pigure 31 shovs
the declines of five
tissues of reer fish
from Belle.
This
figure includes the
data shown by Welander
(1957:Pig.2) in semi-
log plot, for which
his Table 1 gives data
regarding numbers of
specimens and plates.
Values from the indi-
cated numbers of plates
were averaged for each
point.
In addition to
Welander's data, Pigure
31 shows the levels for
one plate of liver and
two plates of muscle for
small fish from a collection made on April
26, 1956.
For each tissue an
initial period of uptake
of nearly two weeks was
followed by a fairly
regular decline ranging
in slope from -1.2 for
liver to -1.9 for skin
(Table 1).
Absolute
levels were comparable to
those of invertebrates.
