ABSTRACT
A study that aims to determine the density and distribution of mangrove
gastropods in pantaiCerminBedagaiSerdang,Sumatra Utara Province in Januari to
Februari 2012 using the survey method. Field data collection using 1x1 m plots
were laid out on the line (belt transect). Determination of observation stations
done purposively sampling at three observation points in the intertidal area.
Biological parameters measured include: density and distribution index
gastropods. Physico-chemical parameters include: temperature, pH, salinity,
dissolved oxygen, substrate organic content and sediment texture. The results
showed that there were 10 species of gastropods with the highest density was kind
Telescopium sp, and distribution patterns for all types of gastropods evenly.
