The study was conducted to evaluate the applicability of producing organic shrimp without using any chemicals in Ilan, Taiwan. The trials respectively employed intensive monoculture of two penaeoid species, white shrimp (Litopenaeus vannamei ) and kuruma prawn (Marsupenaeus japonicus) and extensive polyculture of kuruma prawn (0.56 m-2 stocking density) and grey mullets (500 pcs). Experimental units consisted of three earthen ponds, 900 m2 , 1100 m2 and 4600 m2, respectively with a minimal water exchange.
