Abstract
The overall mean dry biomass of molluscs was highest at Nathiagali (518.684 gm/m2
) followed by Buleji (418.938 gm/m2
), Manora
(408.088 gm/m2
) and Cape Monze (337.365 gm/m2
) during a period of two years from December 1993 to December 1995. The
average dry biomass of molluscs was highest in mid tidal zone followed by high and low tidal zone at Manora, Buleji and Cape
Monze rocky shores whereas, the average biomass was high in low tidal zone followed by high and mid tidal zones at Nathiagali
rocky shore. Cerithium morus (36.88%) predominated at Manora, C. morus (29.15%) and Turbo coronatus (24.93%) co-dominated at
Buleji, Cerithium rubus (16.28%), Trochus stellatus (14.82%), Turbo coronatus (16.92%) at Nathiagali and T. intercostalis (44.52%)
pre-dominated at Cape Monze. The analysis of variance revealed that biomass was significantly different among sites and also among
tidal zones.
