Abalone grow out technology both land based and marine based culture have been well developed worldwide. Some constraint related to maintain the survival of the animal are controlling pest/predators that could reduce the survival rate, other than practical handling and efficiency. Information related to those constraint are insufficient. The objective of this study was to evaluate field experiment abalone grow out technic using 200L PE drum at the bottom surface. The second objective was to improve seaweed farmers by converting the by product of seaweed to be abalone feed.

The construction of the cultivating drum  were installed at the bottom of  intertidal zone with the minimum and maximum depth are 0,6m and 2m. One unit of CPD consisted of 4 drums which were stacked and tied at metal based stage by 7" PE rope. Each  PE drums which was act as outter layer borred with ∅1cm diameter at the all drum surface beneficial for external protector and good water circulation. The inner layer which was made from super  net acted as  cultivating basket equipped with PE net and rope for easy feeding. Feeding the abalone was conducted during low tide or by snorkling to the submersed CPD.

This submersibe cultivating units were also meet the requirement for tourism sectors need by not to expose the construction above the sea water level and create new recreational based aquaculture. Abalone CPD cultured fed with the excess of seaweed showing better growth rate than hanging and floating drum culture. By this static methods were succesfull to reached 6-8cm shell length in 6 month cultivations. With this system operational efectivity was easier and the cultivated animal could be protected due to wild predators.
