Influence of salinity variations on the embryonic and early larval development of long-spined black sea urchin (Diadema Setosum)

Effects of salinity on fertilization, embryonic, and early larval development and growth performances of long-spined black sea urchin (Diademasetosum) were investigated in a controlled laboratory condition. The experiment was carried out with seven salinity treatments (22, 25, 28, 31, 34, 37 and 40p...
