Abstract
A Study on the distribution and abundance of biofouling, Barnacles (Balanus spp)
were conducted in May 2012. The objective of the study was to find out and analyze the
distribution of the barnacle in relation to currents, depth of water.
It revealed that current velocity affected the abundance in that greater current velocity
brought about lower abundance. It addition, the abundance of Barnacles (Balanus spp) were
higher on the subsurface compared to that on the above surface of water. This differences
were due to food supply and duration of filtering activity of Barnacles (Balanus spp).
