Abstract: Length weight relationship is an important tool for fishery management and which will able us to know about size, structure, age and also to assess the health of the host. It will provide various facts about seasonal cycle of the host, growth period of fishes and influential aspect of biotic and abiotic factor. The length-weight relationship of the same species may be different in the population because of feeding, reproduction activities and fishing. Likewise, relative gut length is the useful index used to know about the nature of food and feeding habit. It is therefore necessary to know the length and weight relationships of gutof fishes to understand depends on the nature of food they consume, the length increases with the increase in the vegetable matter in the diet. Most of the literatures show only the length and weight relationship of whole body but not the gut hence this study was conducted to establish the length and weight relationship of alimentary canal compared to the whole body weight of exotic grass carp Ctenopharyngodon idella from Balkhu live fish Market of Kathmandu, Nepal. Ninety fish samples in three phases i.e. first during winter (Magh/Falgun), second in spring (Chaitra/Baishakh) and final during summer (Jestha/Ashad) has been investigated. The weight of carp showed the increasing trend with the increase in length and weight of alimentary canal. The slope value of length was 0.875 and for weight was 0.0714.
