Effect of Lysine on Growth of the Green Tiger Prawn Penaeus semisulcatus de Hann.

Abstract

Using lysine 0.5, 1.0 and 1.5% in the artificial food for the treatments B, C and D while A is a control for feeding the green tiger prawn (Penaeus semisulcatus de Hann). One hundred postlarvae (P15) with an average of 1.2 centimeters body length and 0.005 gram body weight were cultured for 150 days in the concrete pond with the capacity of 2 cubicmeters (1.5 x 4.0 x 0.35 m³). The result shows that there were none significant difference in the growth rate of prawn that feeded on an artificial food with lysine an the control one. However for the fist 30 days, an average growth weight per day of D (120.66%) is considered as the best treatment and others are as C (110.00%), A (108.66%) and B (103.33%) respectively. After that the diminishing of the average growth weight was shown in all treatments. The survival rate of prawn at the end of the experiment were D (92.25%), A (88.25%) B and C (84.25%). The average production of the following treatments were D (384.93), B (335.26), A (334.70) and C 312.45 Kg/Rai/150 days respectively.
