Abstract
Exploitation of shellfish resources can affect its 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 between the dimensions of the shell with its total 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 using PCA. The results show that 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 the increase in width, length and height that was faster than the body weight. The parameters that affects the dimensions of the shell and weight are NH3-N, NO2-N, BOD, salinity, depth, TOM, brightness, Pb, Cd, Hg and temperature.
