Economic Viability of
Rehabilitation of Disease-Prone Prawn-Shrimp Farm By
Chia Boon Tat, Liaw Kok Eng
and Angelito O. Abaoag* |
Sitiawan, Perak is one of the area in Malaysia affected by the devastating disease of tiger prawn. The once 1,000 hectare of ponds dedicated to tiger prawn culture was reduced to less than 100 and are mostly dedicated to white shrimp culture. Some ponds have cultures of tiger prawn but at very high risk. Bionovar were able to develop a system to treat the pond environment, maintaining good water quality and boost prawn/shrimp resistance to disease. This system enables previously abandoned farms to be rehabilitated. BioSEA application provide farmers to seed their farms at the same density as their previous culture, while improving survivability (40% to 85% for tiger prawn and 50 to 90% for white shrimp), increasing average body weight (from 25 to 35g for tiger prawn and 15 to 20g for white shrimp) and increasing the number of cropping per year (1.5 to 2.5). |
