“…A striking feature in the composition of juvenile diet was the presence of considerable quantities of ingested sand, which constituted at least 16.3% of stomach contents (Fig.1). Ingested sand particles, presumably, help in the maceration of food materials in the pyloric stomach as observed in similar studies in some African mullets ((Blaber and Whitfield, 1977;Blay, 1995).…”

An investigation into the food and feeding ecology of the cichlid, Sarotherodon galilaeus multifasciatus in a tropical meteoritic lake in Ghana was undertaken. Stomachs of the fishes, at two length classes, representing adults and juveniles, were examined and the food items identified. The juveniles of Sarotherodon galilaeus multifasciatus feed mainly on insect and insect larvae and relatively small quantities of diatoms but avoiding macrophytes. A striking feature in the composition of juvenile diet was the considerable quantities of ingested sand, which constituted about 16% of stomach contents. Ingested sand may be helpful in maceration of food in the pyloric stomach. A sandy substratum may, therefore, appear ecologically important for juveniles of the species. Adult stomachs contained mainly phytoplankton, chironomid and insect larvae with no ingested sand. No significant differences were found in the stomach contents of the fishes for the dry and wet seasons due, partly, to the lack of any considerable seasonal differences in allochthonous inputs into the lake waters. The fishes exploit a wide range of food resources in the open, sub-littoral and littoral zones of the lake. Further studies to include growth and recruitment are recommended to enhance future production of the species under culture conditions. @ JASEM

“…Other surface-dwelling fish such as Fundulus heteroclitus in salt marshes (Kimball and Able 2012) and Anableps anableps in mangroves (Brenner and Krumme 2007) also alter their habitat during flood tides. Moreover, the POM on which mugilids feed is typically derived from primary producers (Blay 1995;Lin et al 2007). The nearshore water circulation at L was relatively low in this study due to the distance of the study station from the channel (Figure 1), and detritus from seagrass and littoral plants readily accumulated (Huang 2012), providing a significant food source for these detritivorous mugilids.…”

Tidal variation in fish assemblages and trophic structures in tropical Indo-Pacific seagrass beds

et al. 2014

Background: Tidal cycle is an important factor which regularly changes coastal fish assemblages in shallow waters. However, the variations in fish assemblage and trophic structure across tidal cycles in tropical seagrass beds are rarely discussed. We used underwater visual censuses to quantify fish abundance and diversity from the shallow intertidal to the subtidal zone during both flood and ebb tides in seagrass beds surrounding the Dongsha Island, South China Sea. We also recorded fish feeding habits by analyzing stomach contents.

“…These research findings comply with the previous study results. The foods of four juvenile mugilid fishes such as Liza falcipinnis, L. dumerili, Mugil bananensis and M. curema were composed of bacteria, diatoms, blue green algae, protozoan, detritus and particulate organic matter (Blay 1995) with no remarkable seasonal changes in the diet and feeding activities (Blay1995 and Soyinka 2008).…”

This study was conducted in Merbok estuary, Kedah, Malaysia during January to December 2011 to assess monthly and seasonal variation in food items in the stomach of Chelon subviridis and Valamugil buchanani. A total of 341 fish samples (225 for Chelon subviridis and 116 for Valamugil buchanani) were collected from upper zone (Lalang and Sameling Rivers) of Merbok estuary. Among the stomach contents plant materials, diatom, cyanobacteria and detritus were the main food items in both fish species. In both fishes the highest numbers of food items were found in the month of November. Chelon subviridis consumed plant materials 65.84% by number and 8.55% by frequency of occurrence in the dry season whereas 66.25% by number and 9.73% by frequency of occurrence in the wet season. On the other hand, Valamugil buchanani consumed plant materials 59.54% by number and 12.28% by frequency of occurrence in the dry season whereas 72.89% by number and 11.96% by frequency of occurrence in the wet season respectively. Monthly variations of diatom as food item between C. subviridis and V. buchanani were found to be statistically significant (p<0.05). Both of the fish species consumed more food (by numerical method) in wet season than dry season.
