Understanding the diet composition of fishes through gut content analysis is essential for selecting species for aquaculture. Specimens of <i>Fowleria vaiulae</i> and <i>Fowleria variegata</i> were obtained through a trawl survey in the seagrass beds of Palompon, Leyte from November 2011 to February 2012. A total of 291 guts were analysed in this study. Results showed diet composition of both species is mostly made up of benthic invertebrates. A high percentage of chyme was observed in both species (46-65%), suggesting the consumption of easily digested materials. Also for both <i>Fowleria</i> species, it was observed that smaller size classes consume a higher number of small preys while larger size classes feed on larger preys. Small invertebrates such as tanaids and amphipods were more abundant in the guts of <i>F. vaiulae</i> and large preys of shrimps and crabs dominate the diet of <i>F. variegata</i>. This difference may be due to food partitioning in co-occurring species to avoid competition.iv, 25 p.Gut content analysisCardinal fishDiet compositionSeagrass ecosystemsAquacultureMarine resourcesLG 993.5 2015 B5 B53Thesisgutfish consumptionfeeding habitsmarine ecologybiodiversity conservationPhilippinesSDG 14 - Life below waterSDG 2 - Zero hungerSDG 12 - Responsible consumption and productionSDG 15 - Life on land
