carbonic anhydrase,
is believed to be involved in the hydro-
chloric acid secretion of animal stomachs,
it would geem likely
that the concentration of zine in the G. I. tracts of animals
with large,
lacking,
distinct stomachs would be greater than in animals
or with small stomachs.
Since correlation between concentrations of zinc in
certain tissues and the size of the fish was suggested by the
goatfish data,
parametric and non-parametric tests were con~
ducted to examine the possibility of a similar correlation for
surgeonfish.
The results of these statistical testa are sum-
marized in Table 13.
These tests also show a negative correla-
tion between zinc concentrations in eye and muscle tissues and
the size of the fish.

Assorted fish from Lomuilal and Kabelle Islands.
Since 8 specimens of Gnathodentex aureolineatus, a member of
the snapper family
(laitjanidae), were available,
descriptive
Statistics for the data relative to these fish ara presented
in Table 8 for
purposes of comparison with those obtained for
the Kabelle goatfish (Table 6).
These statistics show that
the coefficient of variation of the specific activity of zinc-65
in the eyes of the goatfish is over 4 times that of the snappers
from Kabelle.
This observation is similar to that of Welander
(1957) at Belle Island, Eniwetok Atoll, and may be attributable
