Bullfrogs' daily management techniques

(1) Proper management of the waste from bullfrog tadpoles in the pond is essential. Any leftover bait should be removed promptly to prevent water pollution. The pond should be refilled every 5 to 7 days, adding 7 to 10 centimeters of fresh water each time. The quality of the water used for refilling should be good and clean. It's best to refill the water in the morning between 7 to 8 am or in the afternoon between 4 to 5 pm. Avoid changing the water too frequently, and never add water that contains pesticides, fertilizers, sewage, or very cold spring water. For high-density bullfrog ponds, it’s important to maintain a constant flow of fresh or live water to ensure a healthy environment. (2) Temperature control is crucial for the growth of bullfrog tadpoles. The ideal temperature range is 23 to 25°C. If the water temperature exceeds 35°C, it can severely impact their growth and even lead to death. When the temperature drops below 8°C, the frogs will eat less and stop growing altogether. In early spring, fill the pond with shallow water to help warm it up. During hot seasons, deepen the water, provide shade, or add floating plants like gourds to reduce the temperature and support healthy development. (3) Regular inspections of the pond should be conducted every morning and evening to monitor for any signs of escape or disease. This helps in early detection and quick response to potential problems, ensuring the safety and health of the bullfrogs. (4) Feed quality must be carefully monitored. Never feed spoiled or rotten food to the bullfrogs. Also, avoid using pig feed that contains coarse meal, as it can be hard to digest and may cause intestinal blockages. Consuming such feed can lead to serious digestive issues and even death in bullfrogs. Always ensure the feed is fresh and suitable for their dietary needs. (5) During the metamorphosis stage, when the bullfrog tadpoles begin to develop their front legs, they lose their gills and start breathing through their lungs. As a result, they cannot stay submerged in water for long periods. To support this transition, it's important to keep the environment quiet and stress-free. Additionally, place some logs or other structures in the pond to help the young frogs climb out of the water and complete their transformation successfully.

Mini Locking Plate

The mini locking system can be used for the fixation of ossicles and small bone fragments, osteotomy, arthrodesis, and replantation and reconstruction of ossicles and small bone fragments.

It is composed of micro locking plate 1.5mm/2.0mm/2.4mm/2.7mm series, covering a variety of plate types and a wide range of indications. The plates are all anatomical design, which reduces the need for shaping and helps to reduce the workload of surgeons. Low profile and countersunk screw design can reduce soft tissue injury. Matching orthopedic screws self-tapping design, convenient implantation, screw plum design, reduce screw hexagonal sliding teeth. The composite hole design can not only realize the compression of the fracture end, but also can be used as a locking internal orthopedic fixation frame. Part of the reconstruction structure is convenient for the surgeon to tailor the implant according to the actual situation in the reoperation, and increase the flexibility of the operation. Its indications are mainly phalanx, metacarpal, scaphoid and other carpal bones, ulnar styloid process and capitulum, radial head and styloid process fracture fixation. The 1.5mm orthopedic implants titanium system is mainly used for the middle and proximal phalanx, the 2.0mm orthopedic plates system for the metacarpal bones, the 2.4mm implant locking plate system for the first metacarpal bones and carpal bones, and the 2.7mm mini plate system is mainly used for the distal ulna and radius. According to the clinical research, the micro-locking plate internal fixation in the treatment of multiple comminuted metacarpal fractures can effectively achieve the anatomical reduction and healing required by the clinic. The patients have good postoperative healing, and the functional recovery of the affected limb is good during the postoperative follow-up. It has good clinical effect and can be further promoted and applied.
