Sialang Pasung waters as a part of Selat Air Hitam Waters were the area for operating tidal fishing gears. The height of tide is affect by the moon phase. This research undertaked to compare the catches of stow net as tidal fishing gear at highest tidal condition namely the full moon and the full dark phases. In the village of Sialang Pasung, regency Meranti Islands. This study revealed the composition and the bulk of catches of the stow net which is operated at both phases. The method used in this study is the survey method, collected all need data from the fishing operation spot.Filter net as a trap is classified as a passive fishing gear by utilizing the tidal migratory behavior of fish. So high tidal oscillations associated with moon phases could influence the catch of filter net. But this kind of scientific information, particularly on filter net, has not available yet. Therefore, this study aimed to study the effect of the moon phases on the catch of filter net; to identify the kind of catch and environmental factors. This research was done in Selat Air Hitam waters, based on descriptive method, starting from August 12 nd - 14 th , and September 25-28 th 2018. The main catches of stow net of both phases were pepay shrimp ( Mysis relicta ), and anchovy fish Stolephorus indicus ). While the by-catches are indian mackerel (Rastrelliger kanagurta), Common Hairtail ( Thirchius savala ), Elongated Ilisha ( Iisha elongata ), Bombay duck ( Horpodon neherus ), Dorab wolf-herring ( Chirocentrus dorab ), Mullet (( Valamugil seheli ), Gangetic anchovy ( Tryssa mystax )), spotted scat ( Scatophagus argus ), vanname (( Litopenaeus vannamei ), red prawn ( Paneus monodon ), Mud spiny lobster ( Panulirus sp ), Padachirus ( Psettodes erumeri )), white pomfret ( Pampus argentus ), Sagor catfish ( Hexanematichthys sagor ) and Squid ( Loligo sp .) and Spanish mackerel ( Cybium commersoni ). Full moon phase bring more catches than full dark moon phase in weight. The dominan catches during full moon Bombay duck and Common hairtail.
