Abstract
Estimation of coral fishes biomass is needed as a basic benchmark for assessing the ecological status and fishing potential of coral reefs. Different methods are used to sampling the biomass of these communities, that direct observation is one of the preferred methods with respect to the non-destructive advantage. The purpose of investigation was to estimation standing biomass of coral fishes by Underwater Visual Census method (UVCm) in Abu-Musa Island seasonally from October 2019 to September 2020. also confidence interval was calculated of these estimations from the bootstrapping test (95%). Standing biomass of Coral fish and their confidence interval (95%) by bootstrapping simulation (n=479) were determinated 2923.6 kg., 4576.2 kg, and 1645.4 kg for the stations one, two and three respectively. The difference in the biomass standing of coral fish in three station could be related to the lack of differences in the amount of developed reefs, coral communities and significant differences in habitat availability.  Also, the standing biomass of coral fishes in the Abu-Musa Island are limited, that can be attributed to their low habitat, shortage of carrying capacity and the short life of the Persian Gulf basin, and stress that occurs in the ecosystem, especially bleaching events, that need more study in the future.

Abstract
The dramatic increase in heavy metals, their stable nature, and high toxicity, is gradually becoming a global crisis. In a recent study, a comprehensive assessment of the spatial distribution of heavy metals including Cd, Pb, Ni, Cu, Zn, and Cr was performed in industrial and commercial areas, including the sediments of 32 stations located in the area of Jask, Bandar Abbas, Qeshm, and Bandar Lange during the 2021to 2022. In this area, the concentration of heavy metals showed significant spatial variations between the areas. The maximum concentration of Cd was 0.55 μg/g in the first station of Gasheh. The second station of Khor Langeh had the highest Pb concentration with an average of 10.25 μg/g. The maximum concentration of Cr was 2420.33 μg/g in the second Shahid Bahonar station. The highest Zn concentration of 268.56 μg/g was observed in the first station of Suru beach. In the first station of Shahid Rajaei port, the highest concentration of Cu was observed at 18.36 μg/g. The maximum concentration of Ni was 519.02 μg/g in the second station of Shahid Bahonar.The stations located in Shahid Bahonar port, Suru beach, and Khor Gorsouzuan had a higher pollution intensity than other places and significant pollution risks, especially in terms of Cr, Ni, and Zn. In these areas, Cr was identified as the most dangerous metal. It is necessary to consider comprehensive strategies to control and reduce these heavy metal pollutions, to identify and manage the sources of these pollutions.
