Abstract
The present investigation deals with the assessment of fecundity and gonadosomatic index (GSI) of Schizothorax plagiostomus collected from the river Jhelum, Kashmir. The mean value of fecundity was estimated as 14599 (SD 9219.7) eggs with a mean total length of 34.340 (SD 6.86) and a mean total body weight of 440.60 (SD267.62). The relationship of fecundity with other parameters such as total length, total weight, ovary length and ovary weight were found to be linear and the value of correlation coefficient ® was 0.965, 0.961, 0.933 and 0.972 respectively. The highest value of GSI was recorded in the month of May 12.56 (SD1.81).
Highlights
The present investigation deals with the assessment of fecundity and gonadosomatic index (GSI) of Schizothorax plagiostomus collected from the river Jhelum, Kashmir
The present study is aimed to determine the fecundity and its relation with total body length, total body weight, ovary length & ovary weight) which are useful in increasing the yield of fish species, stock management and assessment in any water body
Ovary structure: The ovaries of Schizothorax plagiostomus was a bilobed fleshy structure occupying a large part of the abdominal cavity
Summary
The present investigation deals with the assessment of fecundity and gonadosomatic index (GSI) of Schizothorax plagiostomus collected from the river Jhelum, Kashmir. The decline of Schizothorax population in the water bodies of Kashmir is taking place due to many factors especially habitat destruction, over fishing, competition for food and breeding grounds from exotic carps, water pollution, etc. These complex factors have altered the landscape and water flow which in turn have reduced the fish stock in water bodies by affecting fish migration, spawning and nursing grounds. The present study is aimed to determine the fecundity and its relation with total body length, total body weight, ovary length & ovary weight) which are useful in increasing the yield of fish species, stock management and assessment in any water body. The present study will be useful in understanding the relationship of fecundity with above mentioned body parameters and serve as a tool for better management of this resource
