Abstract: This study was conducted to determine the density and distribution of ​​Rastrelliger spp. larvae in northern part of West Coast of Peninsular Malaysia. Sampling was conducted thrice at the sampling site (August 2018, September 2018 and October 2019). Larvae were sampled using a larvae net with 500 µm mesh size. Oblique towing of larva net was carried out in study location which was between south of Langkawi Island to south of Kedah waters. Fish larvae samples were observed under stereomicroscopy and identified to family, genus or species level. Larvae were then preserved in 4% formalin. The result showed that the distribution of larvae was occurred more spawning in September compared to August and October. The average size of larvae was 3.1±0.7 mm (n=151). The highest density of Rastrelliger spp. larvae was recorded in September with 38 larvae/1000 m3 where the sampling station was located near fish aggregation device site in Yan. Biological information in this study can be used for fishery resources management in order to ensure the sustainability of fisheries resources.
