Food and Feeding Habits of Some Freshwater Fishes from Ayeyarwady River, Mandalay District, Myanmar

Abstract

Food and feeding habits of the 10 freshwater fish species confined to 7 genera, 6 families and four orders from Ayeyarwady River were studied and estimate between December, 2016 and March, 2017. A total of 100 fishes were randomly collected from the commercial fishermen during the study period. Observation was made for the total length, standard length, body weight, relative length of alimentary canal and qualitative and quantitative analysis of stomach contents. The relative length of alimentary canal was described in relation to feeding habit. The stomach content analysis indicated that six species were carnivores (Notopterus notopterus, Wallago attu, Eutropiichthys vacha, Channa orientalis, Channa punctatus, channa striatus), two species omnivores ( Osteobrama belangeri, Oreochromis sp.) and remaining two species herbivores (Labeo calbasu, Labeo rohita). In the present study, the determination of food composition and feeding habits of studied fish species may give some important information for culture of these freshwater fish species.
