Abstract

The stomach content of Rastrelliger kanagurta was studied by regular monthly collection over the period of 10 months from January 2024 to December 2024. A total of 28 food items were recorded. Seven groups of food items, such as diatoms, dinoflagellates, larvae, algae, copepods, and miscellaneous items were recognized. The dominant diet in the stomach contents was diatoms and copepods. The most dominant items were Chaetoceros spp., Coscinodiscus spp., and copepod species, such as Calanus sp and Eucalanus sp. The analysis indicated that this species feeds mainly on diatoms (61.08%) and copepods (25.41%). The highest actively feeding intensity was observed at 76.5% in October, and the lowest actively feeding intensity was observed at 18.4% in July. 23.1-25.0 cm length group was recorded as the maximum actively feeding intensity (69%). The maximum feeding intensity was recorded in the maturity stage (49.5%), and the minimum feeding intensity was recorded in the ripe stage (15%).
