title: FINE STRUCTURE OF THE SHELL OF DIPLOID AND TRIPLOID OYSTERS, &lt;i&gt;CRASSOSTREA GIGAS&lt;/i&gt; (THUNBERG 1793) (BIVALVIA, OSTREIDAE) REARED IN THE BLACK SEA
abstract: The fine structure and chemical composition of the shell growth margin were compared in diploid and triploid oysters, Crassostrea gigas (Thunberg 1793), reared to commercial size in a Crimean marine farm. The diploid oysters were deposited from plankton, whereas the triploid ones were obtained from an Atlantic coast nursery. An electron scanning microscope SEM Hitachi U 3500 with built-in software Oxford Ultin Max 65 for microanalysis was employed in the study. The shell growth margin is shown t
