Water Quality Parameters and Growth Performance of Freshwater Mud Eel, Monopterus cuchia (Hamilton, 1822) in Different Ditches

Abstract

The experiment was carried out to observe the water quality parameters and growth performance of the freshwater mud eel, Monopterus cuchia at Uthrail union of Sadar upzila under Dinajpur district for six months in different ditches namely as T1, T2 and T3. Randomized Complete Block Design (RCBD) with three replication in each treatment was differentiated at significant level 0.05. Stocking density, feed and fertilization were same for each treatment. The average weights (gm) of the freshwater mud eel, M. cuchia in three treatments were was 316.7±1.8, 403.4±1.4 and 416±1.3, while an average length (cm) was 71.15±1.02, 73.07±0.59 and 75.13±0.88. It also found that the body weight (gm) gain was 221.05± 1.2, 305±0.9 and 318±1.5 while the body length (cm) gain was 16.87±0.8 cm, 17.61±1.2 cm and 18.02±1.09 cm at T1, T2 and T3 respectively. The survival rate was observed maximum (99%) at T2 and minimum was found (60%) at T1. From the study, it can be observed that the highest growth performance of Monopterus cuchia was found in the normal ditch (T3) but survival rate was the lowest. On the basis of survival rate and growth performance, it is suggested that T2 is suitable for the culture of freshwater mud eel, M. cuchia
