Turtle farms primarily raise freshwater turtles (primarily, Chinese softshell turtles as a food source [1] and sliders and cooter turtles for the pet trade); [3] [4] therefore, turtle farming is usually classified as aquaculture. However, some terrestrial tortoises (e.g. Cuora mouhotii) are also raised on farms for the pet trade. [1]
A food web model is a network of food chains. Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.

About 50% of female sea turtles complete "false crawls," which occur when they crawl onto the beach but return to the water without laying eggs.
Sexually mature females of the western pond turtle produce 5–13 eggs per clutch. They deposit eggs either once or twice a year. They may travel some distance from water for egg-laying, moving as much as 0.8 km (1/2 mile) away from and up to 90 m (300 ft) above the nearest source of water, but most nests are within 90 m (300 ft) of water.
