Abstract

Exploitation of shellfish resources can affect growth which can be seen from changes in the size of the shell dimensions including length, width and height. The study was conducted to determine the relationship of the dimensions of the shell with weight as a description of growth patterns, and to determine the environmental factors that affect shell growth. Descriptive method with direct observation technique was carried out at 3 observation stations in the Sunda Strait waters. Data were analyzed using power regression, while the correlation of environmental parameters were analyzed by PCA. The results of the analysis show the correlation between the dimensions of the shell and the total weight of the shell is allometric negative (b <3), which is an unbalanced growth between the dimensions of the shell and the weight of the shell, so that the shell growth pattern is indicated by increasing the width, length and height faster than the body weight. The parameters that affect the dimensions of the shell and weight are NH3-N, NO2-N, BOD, salinity, depth, TOM, Temperature, and PO4
