In the 1971-72 study, conducted during and subsequent to dredging activities, 
42 species of fishes belonging to 24 families were found. The present study 
revealed the presence of 114 species of fishes belonging to 36 families. The 
dusky jawfish (Opistognathus whttehurstt), common along the first reef platform 
in 1971-72, was found to be absent. The absence of this fish is attributed to 
an alteration of the substrate on the first reef by incursion of fine sediments. 
Damage to the second reef observed during 1971-72 was not evident during this 
study.
