Abstract

This research studies the use of local materials, namely cockle shell, mussel shell, mangrove charcoal and mangrove bark from Samut Songkhram province for the adsorption and desorption of nutrients in the lab-scale study. The 300 g of each local material was placed in the 15 L laboratory scale-bucket to observe the nutrients concentration for 15 days of operation in the natural brackish water. Local materials application with marine shrimp during the nursery period in the aquaculture pond was also investigated.  Results from lab-scale experiment revealed that only mussel shell and mangrove bark could adsorb ammonia on the first day, and subsequently all local materials slowly released nutrients in the brackish water. The cockle shell, mussel shell, mangrove charcoal and  mangrove bark  released inorganic nitrogen and ortho-phosphate at the ratios of 10:1, 8:1, 4.6:1, and 1:2, respectively.  Application of mangrove charcoal and mussel shell at the amount of 10.8 and 2 kg, respectively in the 2 m2 net cage for nursery of 2,500 black tiger shrimp (Penaeus monodon) gave the significant higher shrimp length than without local materials at 26 % and heavy metals also can be adsorbed.
