Seven points of hatchling turtle cultivation techniques

Currently, turtle farming has become increasingly popular among both hobbyists and professionals, with many achieving notable economic success. These individuals have found a path toward financial stability and prosperity. However, there are still some farmers who experience limited economic benefits or even incur losses and debt. This is primarily due to the high mortality rates of hatchlings and their low survival rates. While turtles are generally hardy creatures, especially adults, hatchlings are particularly vulnerable. Improper care and management can lead to significant mortality, resulting in substantial financial losses. Below are some key insights and tips for successfully raising hatchlings. When purchasing turtles, it's crucial to select healthy specimens. Look for turtles that are free from deformities, injuries, and appear lively. Ideally, choose turtles with a shell length of around 3 cm for Brazilian turtles, weighing at least 6 grams; for grass turtles, aim for a shell length over 2.6 cm and a width over 2.2 cm, weighing more than 3.5 grams; and for yellow-throated turtles, ensure they weigh over 7 grams. The hatchling pools should ideally be rectangular cement tanks. The floors should be slightly sloped at 2.5 degrees to facilitate drainage and cleaning. This also allows for varying water depths, creating areas for both shallow and deeper water. Place a properly sized cement slab in the pool, allowing for semi-dry and semi-aquatic conditions. This setup benefits the turtles by providing shade, shelter, and a place to bask. It can also double as a feeding area. Prior to introducing hatchlings, thoroughly disinfect the pools using bleach or quicklime. Maintain the pH levels between 7 and 8, ensuring the water is clean and clear with a transparency of about 25-30 cm. For hatchling density, aim for approximately 50-100 turtles per square meter. Higher densities require more frequent water changes, while lower densities allow for water changes every 5 days. Before introducing hatchlings, soak them in a potassium permanganate solution (4 mg/l) or saltwater for about 20 minutes. Ensure the water level remains shallow, around 10-20 cm, increasing gradually as the turtles grow. Maintain the water temperature between 26-30°C, with no more than a 4°C difference between day and night. Add aquatic plants like water hyacinths and water lettuce to help purify the water and provide hiding spots for the turtles. Feeding should focus on animal-based diets. Newly hatched turtles rely on their yolk sac for nutrition for the first 1-2 days. After this period, feed them boiled egg yolks, red worms, and green onions. A week later, introduce minced fish, quail, and animal liver. Feeds should be fresh, finely chopped, soft, and easy to digest. Avoid spoiled or indigestible foods like silkworm cocoons and fatty organs. Feed twice daily, ensuring the total daily intake is 5-10% of the hatchlings' body weight. Always place the food on a designated feeding table, ensuring it is consumed within 2 hours. During winter, two overwintering methods exist: warm breeding or natural hibernation. Historically, juvenile turtles faced higher mortality rates due to smaller size and lower energy reserves. To mitigate this, extend the growth period before winter. For natural hibernation, carefully manage hatchlings for at least two months. Layer the pool floor with 20 cm of damp sand, allowing the turtles to burrow. Keep the sand moist but not overly dry, adding water as needed. Insulate the pool during winter with straw or similar materials to prevent freezing. Gradually reduce temperatures over 5-7 days to avoid sudden cooling, which can be fatal. Preventive measures include regular water changes to maintain freshness. Alternate weekly treatments with 0.01% potassium permanganate solution and 2 mg/l furazolidone. Incorporate terramycin powder or furazolidone into the feed regularly. Disinfect feeding tables with bleach or quicklime. Monitor hatchlings for lethargy or floating behavior, diagnosing and treating issues promptly. Protect hatchlings from predators like cats, dogs, rodents, snakes, and ants. By following these guidelines, farmers can significantly improve hatchling survival rates and achieve sustainable economic benefits.
