Determination of developmental stages of embryo in the Sea Urchin, Echinometra mathaei
Sea Urchin is one of the most useful tools in developmental biology studies because this organism has the simplest kind of developmental stages. We aimed to determine developmental stages and timetable of Echinometra mathaei embryo (the species of Persian Gulf). The spawning of E. mathaei was induced by 0.5M KCl injection (1ml) into the coelomic cavity. After fertilization, embryos were placed ...
متن کاملAntibacterial and Antioxidant Characteristics of Pigments and Coelomic Fluid of Sea Urchin, Echinodermata Mathaei Species, from the Persian Gulf

متن کاملEffects of Salinity on Embryonic and Early Larval Development of a Tropical Sea Urchin, Salmacis sphaeroides
Effects of salinity on fertilization, embryonic stage, and early larval development and growth performances of short-spined white sea urchin, Salmacis sphaeroides were conducted under a controlled laboratory condition. The experiment was carried out with seven salinity treatments (15, 20, 25, 30, 35, 40 and 45 PSU), each of which was triplicated. Significantly highest fertilization success was ...
