Crayfish summer farming management skills

Summer is the peak season for crayfish growth, and it's also a time when various harmful factors can arise. Improving the efficiency of crayfish farming during this period is essential. Here are some key management techniques to consider during the summer months: First, proper stocking is crucial. The success of crayfish farming in summer depends heavily on pond selection and stocking methods. Choose ponds with a stable water supply, clean water, good drainage, and easy access for management. The pond should be sturdy, with walls at least 1 meter high and 3 meters wide at the top to prevent escape. Fencing around the inlet and outlet is necessary to keep crayfish from leaving. A shaded area can be created nearby using vines like melons or gourds to provide cooling. Two weeks before stocking, apply 75–100 kg of slaked lime per acre to disinfect the pond. After mixing the lime into the mud, add 200–500 kg of fermented manure per mu to enrich the water with natural food. Plant aquatic plants like Hydrilla or water hyacinth, but keep them limited to about 10% of the pond area, spread out to allow water circulation. Select healthy, active, and disease-free seedlings, and use a 60–80 mesh net to prevent unwanted species from entering. Maintain water depth between 50–80 cm and transparency of 30–40 cm. Stock in the early morning or late afternoon, with 6,000–8,000 juveniles per acre for 2–6 cm size, or 4,000–6,000 for 3–5 cm. Keep sizes uniform and consider adding white abalone for additional income. Feeding should be scientific. Crayfish are omnivores, eating organic detritus, plants, small animals, and commercial feed. For the first three days after stocking, feed minced fish or meat. After that, introduce small fish, meat, or compound feed. When they grow to 6–7 cm, include crushed snails, vegetables, and other feeds. Feed daily, ensuring no leftovers. Medium-sized crayfish should be fed 15–20% of their body weight, while adults need 5–10%. Feed twice daily, with more at night. Distribute feed evenly around the pond and supplement with aquatic plants like water hyacinth. During hot weather, add animal-based feeds like snails or fish waste. Water quality must be carefully managed. Crayfish thrive in water with dissolved oxygen above 3 mg/L and temperatures between 0°C and 37°C, ideally 18°C to 31°C. Maintain a tea-brown color with 25–30 cm clarity. Apply fertilizer monthly at 150–200 kg per mu. Change water once or twice a week during hot seasons, replacing 20–30% each time. Monitor temperature and oxygen levels. If it gets too hot, use shade structures or deepen the water. If oxygen levels drop, reduce feeding and increase aeration. If crayfish show signs of distress, such as floating or climbing onto the shore, take immediate action by adding fresh water or using an aerator. Disease prevention is vital. Crayfish are sensitive to pesticides, so focus on ecological control and avoid toxic chemicals. Use low-residue, safe pesticides when necessary. Disinfect seedlings before stocking and regularly treat the pond with lime. Add vitamins to the feed to boost immunity. Regular monitoring and quick response to any issues can prevent major outbreaks. Finally, effective management is key. Increase patrols during summer, checking for water quality, oxygen levels, and potential predators like rats, snakes, or birds. Remove any threats immediately. Harvest crayfish regularly every two months to reduce density and improve productivity. Use traps, nets, or dry field harvesting methods to collect them efficiently. Consistent care and attention will lead to better yields and healthier crayfish.

Gas Grill

The gas oven is a modern cooking device that combines efficient heating and easy operation. It uses clean gas as an energy source to heat ingredients quickly and evenly through a precisely controlled flame, and whether it is baking pizza, barbecue or baked bread, it can be easily harnessed to bring mouthwatering taste. Gas ovens are not only easy to operate and quickly preheat, but also energy efficient, making them ideal for modern kitchens and commercial dining venues.
When the Gas Pizza Oven is working, the gas flow is controlled by the gas valve. After the ignition device ignites the gas, the flame burns in the furnace to produce high temperature. Heat is transferred to the pizza through the furnace wall, which heats it evenly and gradually RIPS it. Gas pizza ovens are usually equipped with temperature control systems that can precisely adjust the baking temperature to ensure the baking effect of the pizza.
High efficiency: Gas Pizza Oven heating speed, can reach the required baking temperature in a short time, improve baking efficiency.

Temperature control: Equipped with advanced temperature control system, the baking temperature can be accurately adjusted to meet the baking needs of different pizzas.
Environmental protection and energy saving: Gas as a clean energy, combustion produces less waste gas, less pollution to the environment. At the same time, the gas pizza oven has a high energy efficiency ratio, which can effectively reduce energy consumption.
Easy to clean: Components such as furnaces and baking nets are usually made of easy-to-clean materials, which facilitate daily maintenance and maintenance.
