The Study of bimonthly biomass variations of barnacle on Balanus amphitrite in the Imam Khomeini port

The term ‘‘marine fouling’’ is generally applied to the assemblages of marine organisms that colonize artificial rather than natural substrate. Barnacles (Crustacea) are a dominant component of animal fouling species on artificial and natural substrates, as they are best adapted to sessile way of life. The purpose of this study was to determined deployment recruitment Balanus amphitrite on constructions in the Imam Khomeini Port. To achieve the aims of present research, concrete panels (20 × 30 cm) were designed and installed at depth 3 and 10 meter under seawater level in 4 stations. Panels were collected after 2 months and transferred to the laboratory for further investigations. The results indicated that the B. amphitrite recruitment occurred throughout the year with varying intensities. Maximum biomass of 1943.49 ± 13.74 g.m2 was observed during April 2010 and a minimum value of 4.31± 1.22gr.m2 in February 2009.
