American freshwater turtle
The Emydidae family (Freshwater turtles) is increasingly recognized as a significant pest in aquaculture and irrigation management. As invasive species, they pose a serious threat to managed aquatic ecosystems, often outcompeting native fauna and disrupting the economic stability of agricultural water usage.

American freshwater turtle
Turtles of this family primarily damage fish farms and irrigated agricultural fields such as paddy crops. They feed on juvenile fish and fish eggs, leading to substantial economic losses for fish farmers. Furthermore, their movement through irrigation canals can damage water delivery systems and clog filtration mechanisms.
Their biology is characterized by high reproductive rates and extreme environmental resilience. Females lay eggs in soil near water bodies, and the hatchlings rapidly populate surrounding irrigation ditches and ponds. Their ability to tolerate various environmental conditions ensures their survival in both pristine and agricultural habitats.
The damage caused is twofold: direct consumption of agricultural bio-assets and indirect structural damage. By destroying protective netting and burrowing into irrigation embankments, they compromise the integrity of water infrastructure, which leads to water waste and secondary environmental degradation.
Control measures are vital for preventing population explosions. Recommended strategies include the use of predator-proof perimeter fencing, the deployment of specialized live-capture traps, and regular inspection of banks to destroy nesting sites during the egg-laying season to minimize the next generation's growth.
