Study on Feed Management and Growth Performance of Magur (Clarias batrachus) Fry

Clarias batrachus, widely known as the Asian walking catfish, is a commercially valuable freshwater species in Asia. However, the success of such ventures depends largely on the application of proper culture and management practices. The present study evaluated different protein level on the growth performance of C. batrach us seed over a period of 21 days. Feed ingredients including fish meal, yeast, egg yolk, wheat bran and vitamin-mineral premix were formulated using pearson square method to produce three diets; Diet A (30% crude protein), Diet B (35% crude protein), and Diet C (40% crude protein). Fish seeds fed Diet A reported 25.4 mm length and 125.6 mg weight; seed fed Diet B reached 27.21 mm length and 137.7 mg weight: while Diet C displayed 34.66 mm length and 174.1 mg weight. Statistical analysis reported significant difference in growth performance among the three diets. The result suggested Diet C containing 40% crude protein had the most pronounced positive effect on seed growth and can be recommended for improved production outcomes.
