Özet
The edible sea urchin Paracentrotuslividus is the most common echinoid species in sublittoral habitats in theMediterranean Sea. Biometric parameters (spiny test diameter, spiny testlength, test diameter, test length and weight) were measured on sea urchinscollected from the coast of Antalya. All sea urchins were dissected and indicesof gonad and body components were calculated using wet and dry index method.The results of the study showed that mean test diameters of sea urchins werefound 72.47±0.84 mm with spines, 45.62±0.80 mm without spines. The body wetweight was between 33.68 and 57.81 g. The gonad lops lengths varied between19.73 mm and 23.31 mm amongst the total number of echinoids samples. It wasdetermined that total weight of P. lividus consisted of 21.69% test,25.71% perivisceral liquid, 9.17% gut, 4.12% lantern and 5.29% gonad.
