Babylonia is one of the most significant edibel mullusca species in the world. its more live in coastal and continental shelf region. The ecological basis of the habitats of this mollusk in the coastal waters and in the areas of the continental plateau is a significant help to fishermen and operators. Therefore, in order to identify the ecological characteristics of the Babylon sea snail habitat in the northern waters of the Oman Sea, water sampling was carried out to determine temperature, pH, salinity, dissolved oxygen, nutrients and turbidity, sediment to determine total organic matter and to determine the type of substrate. and from Babylon species to determine the abundance was done monthly from September 2021 to May 2022. The results showed that the average water temperature during the investigation period was 27.79 degrees Celsius in Konarak, 26.99 degrees Celsius in Pezam, and 28.5 degrees Celsius in Pasabandar and Bris. The average salinity in Kanarak, Pozem, Bris and Pasbandar stations is equal to 39.33, 26.99, 39.25 and 39.25 grams per liter respectively, turbidity is equal to 5.48, 2.5, 25 respectively. FTU 7.7 and 25.7, acidity 8.25, 8.22, 8.18 and 8.18 respectively, dissolved oxygen 6.6, 7.06, 6.97 and 6.97 respectively. mg/liter, water nitrate equal to 1.35, 1.16, 1.11 and 1.11 mg/liter respectively, water nitrite equal to 0.04, 0.02, 0.055 and 055 respectively 0.0 mg/liter, ammonia equal to 0.05, 0.19, 0.01 and 0.01 mg/liter respectively, water phosphate equal to 0.37, 0.23, 0.25 and respectively 0.25 mg/liter and the amount of organic matter was 0.64, 0.52, 1.67 and 1.67, respectively. In the research carried out, although the concentration of the measured soluble inorganic nitrogen compounds (nitrate, nitrite and total ammonia) and phosphate has increased significantly, during the multiple linear regression analysis, the amount of nitrite has a high correlation with the amount of catch per unit effort of the snail.
