Presumably, the 90... is being accumulated
throughout the life of the fish and a steady state has not been
reached.
The values for 90. in the ulua (Appendix Table 12)
and the reef fish cannot be directly compared because the bone
of the ulua was analyzed for 305, and only whole eviscerated
reef fish were analyzed.
However, a comparison of Appendix
Table 11 and 12 shows that there can be no great difference in
Oc content between larger, older fish of even the grazing
herbivore and the higher order carnivore.
On the basis of the
differences between 6000 content of goatfish and ulua, it might
be assumed that there is an increasing concentration of the
radionuclide in the ascending food chain.

However, this is
The discrepancy probably exists
because information is lacking on the radionuclide content of
other organisms on which the ulua feed and which could well concentrate
