Tyrosine-derived metabolites in this section do not include spiro-cyclohexadienyl-isoxazolines and related compounds (Sect. 3.22.3.3) or bastadins (Sect. 3.22.3.4), but they do include tyrosine-derived alkaloids that were covered in the Alkaloids section in the first survey (1). The prolific bryozoan Amathia convoluta, collected in Tasmania, has yielded amathamide G (1953) (1814), the latest of several amath-amide alkaloids from the genus Amathia (1). A Florida collection of this animal furnished the new convolutamines A-E (1954—1958) (1815), F (1959), and G (1960) (1425), and a Tasmanian sample of this bryozoan afforded convolutamine H (1961) (1319). A study of Amathia convoluta from the North Carolina coast has yielded volutamides A-E (1962-1966) (1816). Volutamides B and C reduce feeding by the pinfish (Lagodon rhomboids) and the urchin (Arbacia punctulata), respectively, and volutamides B and D are toxic toward larvae of the hydroid Eudendrium carneum. The New Zealand Amathia wilsoni contains the six novel amathaspiramides A-F (1967-1972) (1817).

If one assumes that the basic mechanism for bioconcentration is lipid-water partitioning, one would expect that the extent of chemical uptake by fish should be proportional to its lipid content. Roberts et aL 90) showed that the uptake of chlordane by Northern redhorse suckers is directly related to the size of the lipid pool. Fish which were lean in lipid did not accumulate appreciable compound from treated food. Hansen et al. 45) found that residue levels of a PCB (Aroclor 1254) varied considerably in different tissues of pinfish Lagodon rhomboides) and spot Leiostomus xanthurus) presumably due to variation in lipid content. The PCB concentration was greatest in liver, followed in decreasing order by gills, whole fish, heart, brain, and muscle. Maximum concentration in whole spot was 3.7 X 10 times that in the test water (1 ppb). Chemicals reached plateau levels in fish after about four weeks of continuous exposure. 

A food-passage-rate study in the pinfish (Lagodon rhomboides) was conducted by Peters and Hoss (1974) using e-labeled food. Cerium was selected as a tag because it is poorly assimilated. Peters and Hoss commented that other elements of the rare earth series should also serve as suitable tags and those...
