Abstract

The edible sea urchin Paracentrotus
lividus is the most common echinoid species in sublittoral habitats in the
Mediterranean Sea. Biometric parameters (spiny test diameter, spiny test
length, test diameter, test length and weight) were measured on sea urchins
collected from the coast of Antalya. All sea urchins were dissected and indices
of 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 were
found 72.47±0.84 mm with spines, 45.62±0.80 mm without spines. The body wet
weight was between 33.68 and 57.81 g. The gonad lops lengths varied between
19.73 mm and 23.31 mm amongst the total number of echinoids samples. It was
determined 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.
