Conservation of freshwater turtles, tortoise and terrapin must be based on the natural behavior. Currently, the hatchlings are raised in two ponds at our headstarting facility. Fifty hatchlings are in a larger pond and the rest are in another smaller pond. This is to give larger space for them to swim or move in the ponds. Water in the ponds is replaced twice a week to keep the cleanliness of the ponds. Water salinity and pH are also controlled.

The food is combined of kangkung (Ipomoea aquatica), fruit berembang (Sonneratia sp), pellets.

Pelestarian kura-kura, termasuk merawat kura-kura, harus didasarkan pada perilaku alamiah mereka. Saat ini, keseluruahn anak kura-kura dibesarkan di dua kolam yang ada di fasilitas pembesaran. Sebanyak 50 ekor di kolam yang berukuran lebih besar, sedangkan sisanya sebanyak 30 ekor di kolam yang lebih kecil. Hal ini dilakukan untuk memberikan ruang yang lebih besar bagi mereka untuk berenang dan bergerak di dalam kolam. Air di kolam diganti dua kali seminggu untuk tetap menjaga kebersihan kolam. Tingkat salinitas dan keasaman air juga dikontrol setiap minggu.

Hingga saat ini, makanan dikombinasikan dari kangkung (Ipomoea aquatica), buah berembang (Sonneratia sp.) dan pelet.
