A study on the Length- Weight Relationship and Relative Condition Factor in Glossogobius giuris found in River Singla in the Karimganj district of Assam, India.

Abstract

An attempt had been made to develop a comparative relationship between the length and the weight of Glossogobius giuris and also the Relative condition factor (Kn) collected from the river Singla which is the inlet of one of the biggest wetland, Sone Beel in the Karimganj district of Assam. During the study period the value of exponent ‘n’ in the equation W = cL n was found to be 1.47 for the species. The computed ‘t’ value indicated that the ‘n’ value of the species is significantly different from the expected value ‘3’ and hence the Cube Law W = cL n did not hold good in the case of Glossogobius giuris in the river. The correlation co-efficient (r) in Glossogobius giuris was found to be 1, indicating that there is high positive correlation between length and weight in the species. The relative condition factor (Kn = 1.523) remained greater than 1 for the species indicating their general well being to be good in the river.
