Environmental conditions assessment in the population structure of artificial reef fishes in the Persian Gulf (Bandar-e-Bostaneh and Salakh)

Principal Component Analysis (PCA) was used to determination impact of physic-chemical parameters of waters on fish families in Artificial reefs of in Bandar-e-Bostaneh (Bandar –e-lengeh) ((two areas one station concrete pipe(A.Rp) and second combination of concrete pipe, pyramidal and Reef ball structures(A.Rp,p,b)) and Bandar Salakh(Qeshm island) in period 2017-2018 seasonally. The PCA results of physical-chemical parameters(temperature, pH, dissolved oxygen, salinity, chlorophyll-a, ammoniac, nitrate, nitrite, phosphateand turbidity), and aquatic families number showed a significant relationship in A.Rp.kh (Sphyraenidae,pomacentridae,apogonidae, serranidae,nemipteridae, soft coral and sponge), A.Rp(Lutjanidae, Sphyraenidae, apogonidae and serranidae) and A.Rp, p, b (Lutjanidae, serranidae and sponge) to other aquatic animals. In addition, the results of pearson test showed that between the total number of aquatic animals and the temperature (R2= -0.58), chlorophyll a (R2 = 0.86), nitrate (R2 = 0/38), and turbidity (R2 = 0.64), and between sphyraenidae and temperature (R2 = -0/36), and lutjanilade and chlorophyll a (R2 = 0/38), have a significant correlation with 95% probability level (P <0.05).In this study, the effect of environmental factors on fish families of artificial reefs in Bandar-e-Bostaneh and Bandar-e-Salkh was concluded.
