Objective Method Urchins individual samples are anticipated anc all will be surveyed for relative activity levels. A selected number, probably no more than 200 will be quantitatively analyzed. Included in the latter estimate are all species used. in the diet. Some selected shel? and coral will be carefully analyzed and correlated with growth rates, concentrations, as indicators of changes in the environment as a function of time. Sea cucumber Clams Coral Starfish Langusta 3) Gut contents of bottom-feeding fish collected in different areas will be analyzed to assess concentration levels in lagoon areas. . Comparison of the activity levels in each of the above sample types will be used to contour activity levels in the lagoon and reef. sample types, especially edible organisms, will be used for dose assessment. : Field : sample preparation and analysis. recommendations will be forwarded to the laboratory for guidance in satefbaniadns Food chain dose assessment requirements Purpose: oe ! Data from many edible marine species. a To provide samples in order. to determine the activity levels in all The data are required to assess dose from aquatic food sources, There will be close coordination with the radiological assessment team who will generate the information regarding Marshallese diet and define the percentage of each marine trophic level in the diet. This information is necessary to determine the sample size of a species needed, type of species, and post-treatment method of the sample. Assessment of the levels of activity in carnivores, bottom feeding carnivores, omnivores, herbivores and all invertebrates will be nai made. Dietary habits of the Marshallese people will be considered in the treatment of samples. Some species may be consumed whole, these defined specimens will be made on the entire fish. The analysis on For those species where only the flesh or other organs are consumed, the samples will be dissected from different areas will be determined. areas visited by the 1964 survey team. 4 Miatie 5 TM ied nmete. The variability in activity levels in similar species nee and the tissue analyzed. Sampling sites will include those Fishing methods will include trawls, gill nets, long lines, traps, rod and reel, and spearing. Although the fishing will be operationally defined, 200 to 300 samples are anticipated for quantitative “25.
