Description 2130-2135
The shore protection
measures currently adopted in India
includes deployment of sand filled geosynthetic containers for coast-line
stabilization.  Interestingly, it is
observed that such geosynthetics containers are colonized by alphabetic
organisms such as algae and sessile marine invertebrates that are native to the
natural rocky habitats, thus providing refuges and nursery grounds for fish and
crustaceans. However, the epibiotic assemblages that are developed on a
submerged hard substrate (breakwater) and on nearby coastal natural rocky
substrate are different from the epibiota developed on sand-filled geosynthetic
containers, probably due to the physical properties of the substratum affecting
organism recruitment. Little attention has been paid until the last decades to
studies on the epibiota on man-made coastal defense structures. The biotic
community structural studies of macro-faunal assemblage on geotube deployed at
Kovalam coast revealed around 13 species of epibenthos dominated by
non-invasive brown mussels, a recruitment pattern mimicking the adjoining
natural rocky substrate. The biotic assemblage on geotubes revealed the
ecofriendly nature of the low crested coastal protection structures.
