Green mussel culture development is still dependent on the availability of seed or called spat derived from nature, so knowledge about the collector or attachment of spat and appropriate collection methods should be known. This research aims to determine the most optimal method to collected green mussel spat on the coastal waters Kuala Langsa, Aceh. Based on parametric t-test, showed if the production potential spat covering production (g), the total spat collected (individual per collector 2 m) and average length (mm) on both longline and stick method which different significantly (P<0.05). Spat production with longline method of 3713.50 ± 53.40 g, where total spat collected as much as 175.75 ± 12.63 individuals per collector 2 m, with average length of 7.33 ± 1.22 mm, while the spat production with stick method of 2613.35 ± 28.80 g, where total of spat collected as much as 86.25 ± 13.72 individuals per collector 2 m, with average length of 6.76 ± 1.44 mm. Parameters of water quality during spat collection period is still appropriate for support green mussels life, where the temperature ranges from 28.9 to 34° C, salinity of 26.6 to 30.1 ppt, turbidity of 20 to 22 cm, pH of 7.9 to 8.3 and DO of 4.9 to 6.0 mg/l and the water current of 0.1 to 0.3 m/s. Green mussel spat collected with longline method showed optimal results to be practiced in the coastal waters Kuala Langsa, Aceh.
