Abstract

The dog conch, Laevistrombus canarium (Linnaeus, 1758) is a highly important fishery specie with high potential for aquaculture. However, not much information is available regarding the feeding and nutrition of the species. The purpose of this study is to investigate the aspect of feeding ecology of the conch by observing their feeding behavior, food preferences and analysis of the stomach content. Field sampling and observations were conducted in the seagrass bed area of the Merambong Shoal, Johor, Malaysia from January to July 2006. For stomach content analysis, 30 conch individuals were sampled and their stomach contents were analyzed under light microscopy. Laevitrombus canarium feeds mostly on the thin uppermost layer of surface sediment and occasionally graze upon the seagrass epiphytes. However, they never purposely consume the seagrass or macrophyte itself. The gut content analysis (N = 30) showed gut fullness score ranged from 3 to 4 (mean = 3.6 ± 0.24) of the maximum score of 5. Detritus formed the most dominant food item, followed by macroalgae and fresh seagrasses (Halophila sp.
