The aim of the present study was to work out the natural food and feeding habits of Macrobrachium dayanum in Gho-Manhasa Stream Jammu. Samples were collected monthly between January 2004 and December 2004. A total of 480 specimens of Macrobrachium dayanum (M. dayanum) were analysed by categorizing them into four categories based on size and sex. Out of total 480 analysed specimens 214 (44.58%) guts were found to be empty while about 266 (55.41%) contained food. The frequency of empty stomachs decreased with increasing size. Index of preponderance revealed that detritus was the dominant food item of M. dayanum. Algae, the second most dominant food item was found to decrease with increase in size. After detritus and algae other important food items were found to be insecta, sand, annelids, macrophytes, mollusca, unidentified matter, crustacean and Rotifers. Based on overall analysisrnof different size groups the M. dayanum has been categorized as detriti-omnivore feeding on both animal and plant matter with detritus as dominant food item.Pages: 33-38 | 832 Views 12 DownloadsDownload Full Article:
