Bag nets is one of method who can be a solution for that problems. The aim of this research are want to know about daily growth rate (DGR) and absolute growth rate (AGR) from seaweed E. Spinosum. This research has been done in August – September 2019. The net bags was designed to be strong enough for protect seaweed from predation and strong current at there. The net bags prepared are 56 nets, with initial weight of seaweed 50 grams. The result of this research show the daily growth rate (DGR) was 5.6 % each day and for absolute growth rate (AGR) was 304.9 grams. The growth rate is good enough because growth more than 2% each day.
