Effect efficiency of the fragmentation method to asexual reproduction of Stichodactyla haddoni

This study examines the effect of half and quarter separation methods by fragmentation for culture sea anemone Stichodactyla haddoni (with mouth diameter 28.97±1.37 cm, foot diameter 9.39±0.44 cm, weight 1466.78 ± 192.13g) after 90 days in recirculating aquaculture systems. Research using a completely randomized design with three treatments: control, 1 to 2 individuals and 1 to 4 individuals. Each treatment repeated three replications. The results show that the survival was high, with 88.89±11.111% in control and 88.89 ±5.556% in the anemones cut in half, and 72.22±2,778 % cut in quarters (p>0.05). There was a difference in growth in mouth diameter (p<0.05) but no difference in growth in foot diameter and wet weight (p>0.05). Anemones were cut in half larger, less stressed, and grow faster than the quartered individuals, but the number of anemones from the quaternary separation method was higher. Experiments show that both fragmentation methods are highly effective and can be used to breed Stichodactyla haddoni anemone.
