against its respective antigen <strong>and</strong> stomach contents, <strong>and</strong> the reaction<br />

examined for lines of identity (see Figure 13c).<br />

Tables 28 <strong>and</strong> 30 give the results of these tests. X's indicate that<br />

precipitin lines were present on the first test. Underlined X's indicate<br />

that the second test showed a positive line of identity, confirming that<br />

prey item existed in the stomach. X's not underlined may or may not be<br />

prey items. Present immunological evidence can neither confirm nor deny<br />

their being prey items. Only those items showing a positive reaction<br />

after retesting are considered to have been detected for this report.<br />

For the larger juvenile king crabs (CL >50 mm) (Tables 27 <strong>and</strong> 28), the<br />

immunoassay detected a maldanid polychaete, the clam, Spisula polynyma,<br />

pagurid crab, <strong>and</strong> a tunicate in stomachs where these items were undetected<br />

by visual examination. For Spisula polynyma, the immunoassay detected<br />

this clam in 4 cases where it was not detected visually. Visual<br />

examination detected S. polynyma in 5 cases where the immunoassay did not<br />

detect the clam or failed to give a positive detection when retested for<br />

lines of identity.<br />

For yearling juvenile king crab (CL
