Growth of green mussel (Perna viridis L.) culture at two different depths in estuary waters of Alue Naga Village, Banda Aceh

Abstract

Green mussel (Perna viridis L.) is one of economically valuable shellfish that can be potentially developed to support the people economic income. This study aimed to investigate the growth performance of green mussels at two different groups. Two groups of 15-individual green mussels’ culture was cultured repeatedly forthree times.. The two groups treatment used were 0.9 m depth and on the surface of the water. TThe growth performances were quantified in terms ofweight gain, length gain, daily growth rate, daily length growth rate, specific growth rate, specific length rate. Result showed that green mussels with a depth of 0.9 m and water surface were weight gain, length gain, daily growth rate, daily length growth rate, specific growth rate, specific length rate by values of 10.33±0.43 g, 38.12±2.02 mm, 0.11±0.004 gr/day, 0.39±0.02 mm/day, 1.60±0.11 %/day, and 0.80±0.02 %/day and 8.09±0.21 g, 33.66±0.92 mm, 0.08±0.002 g/day, 0,34±0.01, 1.27±0.03 %/day and 0.74±0.02 %/day, respectively. The growth performance of 0.9 m depth culture were significantly better that water surface culture. Therefore, it is concluded that the 0.9 m of green mussel culture is suggested to obtain the better growth performance.
