Tiram (Crassostrea sp.) merupakan filum dari molluska dari genus Crassostrea yang menempel pada benda keras dan bersifat filter feeder. Tiram juga hewan yang salah satunya memiliki bentuk cangkang yang tidak beraturan dan pertumbuhannya sangat dipengaruhi oleh faktor biotik dan abiotik.Pola pertumbuhan tiram sangatlah berpengaruh terhadap panjang-berat tiram. Penelitian ini bertujuan untuk menganalisis pola pertumbuhan tiram (Crassostrea sp.) meliputi hubungan panjang dan berat, faktor kondisi dan sebaran kelas di Perairan Alue Naga dan Lamtengoh. Pengambilan data menggunakan metode purposive sampling dimana penentuan lokasinya berdasarkan atas adanya keberadaan tiram. Hasil dari penelitian ini ialah pola pertumbuhan tiram (Crassostrea sp.) bersifat alometrik negatif di perairan Alue Naga dan isometrik di perairan Lamtengoh. Hasil penelitian hubungan panjang dan berat pada penelitian ini menunjukkan nilai b=2,1344 (b

ABSTRACT Oysters (Crassostrea sp.) are a phylum of mollusks from the genus Crassostrea that attach to hard objects and are filter feeders. Oysters are also animals, one of which has an irregular shell shape and its growth is greatly influenced by biotic and abiotic factors. The growth pattern of oysters greatly influences the length and weight of the oyster. This research aims to analyze the growth patterns of oysters (Crassostrea sp.) including the relationship between length and weight, condition factors and class distribution in Alue Naga and Lamtengoh waters. Data collection uses a purposive sampling method where location is determined based on the presence of oysters. The results of this research are that the growth pattern of oysters (Crassostrea sp.) is negative allometric in Alue Naga waters and isometric in Lamtengoh waters. The results of research on the relationship between length and weight in this study showed a value of b=2.1344 (b
