Comparative morphological analysis of diploid and triploid oysters, Crassostrea gigas, farmed in the Black Sea
Triploid organisms, in particular oysters, are widely used in marine aquaculture. However, the advantage of triploid oysters compared to diploids has not been proven in all cases. Comparative morphological analysis of Pacific oysters Crassostrea gigas of different ploidy levels allows evaluating the...

Triploid organisms, in particular oysters, are widely used in marine aquaculture. However, the advantage of triploid oysters compared to diploids has not been proven in all cases. Comparative morphological analysis of Pacific oysters Crassostrea gigas of different ploidy levels allows evaluating the benefits of raising triploids in the Black Sea. First, the morphological characteristics of diploid and triploid Pacific oysters C. gigas farmed in the Black Sea were studied. Allometric ratios of weight W, g and shell height H, mm of oysters were obtained, which are described by the equations W$_{2n}$ = 4 × 10$^{-4}$ × H$_{2n}$ $^{2.56}$, R2 = 0.86 and W$_{3n}$ = 9 × 10$^{-5}$ × H$_{3n}$ $^{2.90}$, R$^{2}$ = 0.91.
