AbstractSea cucumbers (Echinodermata: Holothuroidea), has high nutritional value in south east countries with high price in food market. This echinoderm has high medicinal importance base on active and chemical compositions which are more used in pharmacy industries. In this study, proximate composition of Holothuria leucospilota divers from Sistan and Baluchistan and Hormozgan to some parts of Bushehr provinces which were caught by diving, during Autumn and winter 2016 and Spring and Summer 2017, determined. For this, one station was selected in each province, three specimens from each three replication of different seasons sampled. In nutrition laboratory of Arazist Parsian Mehr consultees Co. Fars Province, all specimens from replication of each season of separated province, minced and analyzed proximate compositions protein, lipid, Ash and Humidity based on standard methods. Results showed that this sea cucumber species compromised relative high protein level. The highest protein content was found in Hormozgan at summer season (15±3.69) and lowest not significantly in Bushehr at autumn season (10±1.73) and Sistan and Baluchistan province at spring season (10±1.8), caused by higher WT. and chlorophyll a contents in sea cucumber caught in Hormozgan st summer season compare to samples from other studies provinces at the same seasons. Humidity percentage were the highest in the sea cucumber caught at winter time both in Bushehr (86.1±8.43) and Sistan – Baluchistan (86.1±7.43) provinces not significantly(P>0.05), while the lowest was obtained from Hormozgan samples at spring season (81.1±5.63). Lipid contents with low levels in this species showed the highest in Sistan and Baluchistan province at winter season (0.29±0.08) and the lowest lipid content was obtained from sampled in Hormozgan province at Summer time (0.12±0.02). Ash body content of H. leucospilota species was the highest in samples from Bushehr province at winter season (3.0±0.24) and the lowest ash was found in specimens from Hormozgan province at winter season (2.08±0.24). As conclusion, H. leucospilota from Hormozgan speciallity in summer season, has higher protein and can be affected on price indexs.
