MAHA SARAKHAM: Farmers in Maha Sarakham Province have successfully transitioned from traditional rice cultivation to raising ornamental carp in converted rice fields, yielding significant financial gains in just six months. This innovative approach has demonstrated the viability of carp farming as a profitable alternative, providing incomes exceeding 100,000 baht per cycle.
According to Thai News Agency, Lt. Natthasan Sirikij, who leads the community enterprise for carp farmers in Ban Tiew, Khao Subdistrict, initiated this venture by first experimenting with a single pond. The ease of raising carp, along with their favorable market prices, encouraged Lt. Sirikij to transform his 5 rai rice field into a carp pond. This strategic shift has proven beneficial, as the ornamental fish are in high demand.
The key to successful carp farming lies in maintaining optimal water quality. Ponds are constructed to dimensions of 10 meters in width, 15 meters in length, and a depth between 80 to 150 centimeters, which facil
itates both fish health and ease of harvesting. Too shallow a pond results in overheating due to sunlight, while depths exceeding 150 centimeters complicate netting operations. Prior to stocking, ponds undergo a cleaning process, with water left to settle for up to three weeks to achieve a pH balance between 6.5 and 8. Protective nets are installed to safeguard against predators like monitor lizards and snakes.
Fish fry are introduced at a cost of 15 baht each, with a recommended stocking density of 3,000 fry per pond to avoid the necessity of an oxygenation system. Nutritional needs are met with catfish feed containing 30-35% protein, supplemented by water hyacinth eggs every ten days, enhancing fish growth and coloration while reducing feed expenses. Over a period of three to six months, these practices lead to a substantial profit margin, as fish raised at a cost of 15 baht can be sold for 60 baht each, translating to more than 100,000 baht per pond.
Lt. Sirikij’s carp farming model underscores the poten
tial for traditional farmers to diversify and increase their income through aquaculture, providing a sustainable alternative to rice farming in the region.
