Description 74-84
Intensive
sampling was carried out in the marine environment of Mumbai and Jawaharlal Nehru
ports to investigate the composition of benthic sessile population on three
different occasions during 2001 to 2002. this study recorded 29 species of hard
substratum fauna and 14 associated fauna. The acorn barnacle Balanus amphitrite and tube dwelling
polychaete Protula tubularia were the dominant hard
substratum species recorded from the area. Protula
tubularia with no previous records from Indian waters appears to be an
introduction in the region. The bivalve Mytilopsis
sallei, which has been reported earlier as an invasive species Indian
waters, was mostly found restricted to enclosed habitat within the ports. A
comparison with historic data, based on the literature available, indicates the
presence of 15 taxa which appeared for the first time this locality the present
study envisages that the hard substratum faunal composition in Mumbai harbour
environment is changing due to ever increasing human perturbation.
