ABSTRACT

This research has been conducted in Kotania bay, Seram Island, Maluku. In order to find out the density of blood cockles used line transect methods in seven sampling stations and Morisita index used to determine the pattern of spreading. The results showed that the cockles with the highest density was found at station 5 is 10.06 psc/ sq.m., whereas the lowest at station 6 is 0.53 psc/sq.m. The cockles spread between 10 to 60 meters on the beach from the mean tidal level to form a clumped-type distribution. The density of blood cocles tends of to increase at the stations that have a high content of organic material, especially in the muddy bottom substrate.
