Second, the construction of turtle ponds.
When family-style turtles are raised, turtles can be farmed under existing conditions. The following describes the experience and methods of building turtle ponds at the leading museum of amphibians and reptiles in Haining, Zhejiang Province for your reference.
1. The turtle pool. The pro-turtle pool requires open water and sunny shelter. There should not be tall buildings around the pool, but there must be a certain height of the wall to be isolated from the outside world. The bottom of the pool requires mud or sandy soil, no cold soaking, no leakage. Adequate water supply, no pollution, convenient drainage and irrigation. The turtle pool is composed of two parts: the pool and the dry land. The dry land is divided into two parts: the sports ground (feeding platform) and the sandy land. The pool and the dry land are connected by a 30-degree slope, so that the turtle can climb to the sand pool and dig holes to lay eggs.
The stocking density of the pro-turtle should not be too large. Each mu of aquaculture water should be stocked with 600 kg of turtles and 3 eggs per square meter. The turtle pool is preferably a rectangle with a surface area ratio of about 7:3 and a water depth of 0.5 m to 1 m. The three sides of the pool are preferably steep slopes, so that the turtle cannot go up and down; the other side is a gentle slope, and the slope ratio is 1:3. Turtle ponds should be planted with more trees and grass around them to try to simulate the natural ecological environment and be conducive to breeding turtles.
2. Hidden turtle pool. The hatchery pool generally requires a cement masonry structure that can be built both indoors and outdoors. The area should not be large, about 10 square meters, the pool depth of 50 cm, depth of water 10 cm to 30 cm, can be built into a long strip pool, the pool can also be divided into a number of small grid. The water on the other side of the pond is left on land, and the land and the pool are connected by a 30-degree slope, which facilitates the hatchlings to sun back and rest. The food table is located on the platform where the pool meets the land, allowing the hatchlings to feed and clean up the remaining food in time. Chicks are petite, frail, and have a poor ability to defend against invasion by external enemies. Therefore, it is best to cover the juvenile turtle pool with wire mesh to reduce unnecessary losses.
3 baby turtle pool. At present, young turtle breeding uses warming and feeding methods. Juvenile turtle area should not be too large, about 30 square meters to 50 square meters, the pool is rectangular, cement masonry structure, the pool wall is about 1 meter high. The bottom of the pool is covered with a layer of 10cm thick sand, and one side of the pool is made of bricks or cement boards to form a platform parallel to the water surface for turtles to inhabit and sun back. Close to the cement platform, use a cement board or wood board to set up the feed table. Generally, when warming and feeding, keep the water temperature between 26°C and 30°C so that the young turtle will grow rapidly in the stable water temperature keeping pond.
4. Adult turtle pool. Adult turtles can be reared in a turtle-to-fish culture mode. Most of them use common fish ponds, but they must add a 50-cm-high anti-flight wall to the dike.
