Ecological monitoring on artificial reefs in the Persian Gulf (Bandar Lengeh)
Along with the development of aquaculture, artificial reefs created is one of important ways Offset the decline in fish stocks and Increased fishing. Accordingly, the project was based. Sampling for Fish at 21 stations structures and two control stations and two Control stations and for Ichthyoplankton, benthos and physicochemical factors in water at two stations from autumn 2010 to summer 2011 were conducted seasonal. The artificial reef in seven rows different structures and three rows deep (depth of 8, 9.5 and 11 m) were established in the region of Molo( Bandar Lengeh). CPUE , frequency and species diversity of species, showed significant differences between seventh row (mixed structures) and six other rows (P<0.05. In this study, significant differences were not observed between different depths (P>0.05). Although mean CPUE showed high seasonal differences, but because analogous variance was also significantly different (P<0.05) ANOVA could not confirm significant seasonal difference for CPUE. Prepared video films displayed species several times more than trapped ones, around artificial structures. There were also 11 species around the structures that were not caught by Graps. In this study, 7 families of Ichthyoplankton were identified, including Clupeidae, Lutjanidae, Engraulidae, Gobiidae, Sciaenidae, Sparidae and the Carangidae.The highest annual average (53.97 percent) belonged to the family Gobiidae. In Ichthyoplankton, the families Gobiidae, Sciaenidae and Lutjanidae had the highest annual density. Benthos were observed in 57 genera and family groups, included crustaceans, molluscs, protozoa (foraminifera), nematodes, nemertines, Polychaete, ophiurids and hydra. Statistically significant difference between the density of organisms found in different structures. Despite significant seasonal differences between some physical and chemical factors (P<0.05), there was no significant difference between the stations. Mean water temperature in establishment area of structures were obtained in spring 30.77±0.07, in summer 33.86±0.026, in autumn 26.65±0.5, in winter 21.91±0.034°C. pH with an average of 8.02±0.11, due to the buffering effect of seawater with little change (7.74-8.23) were. Annual average turbidity was 5.83±2.86 FTU with range 1.83–13.52. The mean annual salinity and dissolved oxygen was 5.56±0.36 ppm and 37.42±0.36 ppt and the range 4.93-6.41 and 36.93-38.51, respectively.
