The Length-Weight Relationship (LWR) and relative condition factor (Kn) of Mud eel (Monopterus cuchia) from three different areas of Meghalaya were studied. The data was analyzed using the formula: W=aL^b. The values of regression co-efficient ‘b’ indicate a positive allometric growth pattern of the fish due to higher proficiency in feeding. The values of correlation co-efficient proved to be highly significant. It also exhibits a high degree of positive correlation between the length and weight of the species. The values of relative condition factor ‘Kn’ indicate a good well-being of the fish. High relative condition factor (Kn) value proved that condition factor increased with increasing length and weight of the species. The results revealed a healthy habitat conditions. The Length-Weight Relationship and relative condition factor showed that the growth of Monopterus cuchia from three different areas of Meghalaya is quite satisfactory.
