The relationship between weight and morphometric size of genus Margarites (Mollusca) in Manado coast, North Sulawesi

This study aims to analyze the relationship between the weight and morphometric parameters of the genus Margarites. Sampling used quadrate line transect, and the morphometric data were determined using ImageJ software, while data analysis used principle component analysis (PCA) to reduce the data, then applied a multiple regression. Results showed that FERET ANGLE variables influenced the weight of the genus Margarites so these variables have a very important role in the growth of the genus. All morphometric variables could be included in the model (p < 0.05) to explain the weight variable.
