Crocodile feeding methods and supply and demand

First, the method. 1. **Correct Location** The entire area is in excellent condition with no industrial, pesticide, or domestic pollution. There is a sufficient and clean water supply, fresh air, and no soil contamination. The fish ponds at the crocodile breeding base are located in fertile soil, maintain good environmental hygiene, and have a fresh atmosphere. 2. **Fish Pond Facilities** (1) The crocodile farming area covers 225 acres, with each pond ranging from 1 to 2 acres. The bottom of the ponds is flat, with silt depth less than 20 cm, and water depth between 1 to 1.5 meters. A one-meter-high wall surrounds each pond to prevent crocodiles from escaping and to keep outsiders away. The ratio of water surface to land area inside the wall is approximately 1:1, which is ideal for crocodile growth. (2) Fish such as tilapia, cockroaches, and snails are raised in soil ponds covering a total of 165 mu, with each pond being 8–10 mu in size. The bottom is flat, with silt depth not exceeding 20 cm, and water depth between 1.5 to 2 meters. 3. **Crocodile Species Selection** The main species bred include the Siamese crocodile, Nile crocodile, and other common crocodile varieties. 4. **Disinfection and Preparation** Before stocking, the ponds are cleaned, disinfected, and water quality is adjusted to ensure optimal conditions for the crocodiles. 5. **Water Quality Monitoring** A dedicated quality control team oversees the water quality and safety of the breeding base. They closely monitor the surrounding environment to detect any potential threats, such as pesticide spraying, changes in water sources, or water quality issues. In case of any problems, they work with fisheries and environmental protection agencies to take immediate corrective actions. The Guangdong Fisheries Quality Supervision and Inspection Center was commissioned to evaluate the environmental quality of the area. The report confirmed that the water meets the standards set by "Quality of Freshwater Aquaculture Water for Non-Environmental Foods" (NY5051-2001). 6. **Selection of Fry** Healthy, disease-free, and inspected self-bred crocodiles or imported seedlings from Thailand are selected for stocking. Similarly, healthy tilapia, cockroaches, and quails are chosen as feed fish. 7. **Stocking Density** For crocodiles with body lengths between 30–100 cm (3–10 kg), the stocking density is 200–300 per mu. For feed fish like tilapia, clams, and cockroaches, the density follows standard practices, with a policy of "catching large and keeping small" to optimize growth. 8. **Feeding Methods** (1) Crocodiles are fed with self-raised, fresh fish such as tilapia, oysters, and clams. Ponds are regularly refilled with new water. Large crocodiles weighing over 30 kg are harvested and processed, while smaller ones continue to be cultured. (2) Tilapia, cockroaches, and clams are mainly fed with mixed feed including corn and wheat bran. Scientific feeding methods are used, along with regular applications of quicklime, beneficial microorganisms, and water quality improvers. Aerators and aeration pumps are also used to maintain good water conditions. Again, the "catch large and keep small" principle is applied to ensure the feed meets the requirements for crocodiles. 9. **Daily Management Measures** The base uses self-raised, fresh fish to feed the crocodiles. All operations are managed uniformly, and technical staff receive training in crocodile health care, feeding, and disease prevention. Daily management includes: (1) Regular monitoring of water quality, with tests conducted every 10 days at the water source and every 15 days in the aquaculture ponds. Standards follow NY5051-2001, with pH between 7–8.5, transparency around 30 cm, and dissolved oxygen above 4 mg/L. Water samples were tested by the Guangdong Fisheries Quality Supervision and Inspection Center, and all 12 parameters—color, smell, taste, total coliforms, heavy metals, and others—met the required standards. (2) Production personnel maintain detailed records of seedstock origin, growth, feed use, and water quality changes. This helps in creating scientific breeding plans that promote healthy development. (3) Feed, additives, and medications are used correctly. All crocodiles are fed live tilapia, cockroaches, and clams raised on-site. Feeding amounts are adjusted based on crocodile activity, water quality, and weather. Spoiled fish are strictly prohibited. Tilapia, clams, and cockroaches are not given unapproved feed or additives, and the use of illicit drugs is banned. Disease prevention follows a "prevention first" approach, using biological agents and minimizing chemical drug usage. (4) During winter, when temperatures drop below 15°C, crocodiles become inactive. To protect them, we cover the pools with thin film and pump warm water from deep wells into the ponds. We also increase their food intake to support continued growth during colder months. This comprehensive approach ensures a safe, sustainable, and high-quality crocodile breeding operation.
