Attempts to apply the same farming techniques to other Asian softshells species have not succeeded. It is generally considered that hard shelled turtles and tortoises grow too slowly for them to become economically attractive for farming.
Historically, the market prices for most hard shelled turtles and tortoises had been generally similar regardless of species. An exception to this is [Cuora trifasciata] which traditional Chinese medicine places a higher value on, consequently driving up demand and price. This has resulted in small scale grass roots type "ranching" of [C. trifasciata] in China, the scale of which is unknown. The Vietnamese people are fond of keeping [Geomyda spengleri] as pets and in these instances, breeding is known to occur. In 1997 and 1998 an influx of neonate [Cuora flavomarginata], [Ocadia sinensis], [Mauremys mutica], and to a lesser degree, [Cuora galbinifrons] and [Pyxidea mouhotii] have appeared in the Mong Kok pet markets in Hong Kong. Due to the small size of the turtles, they may be well suited to pet market economics and be farm raised. Commercial opportunities from the pet sector could provide the necessary incentive to ranch the hard shell species thus creating a self sustaining supply and becoming a [de facto] conservation activity, perhaps buying some time for these species.
