Stocking Conditions: 2) The water temperature in the pond must be above 14°C, but not lower than 12°C. It's important to maintain a stable temperature to avoid stress on the young shrimp. 3) The salinity of the shrimp pond should ideally be kept between 20 to 32 parts per thousand (‰). When transferring seedlings from the nursery room, the salinity difference should not exceed 5 ‰ to prevent shock or mortality due to sudden changes. 4) The pH level of the water should be between 7.8 and 8.6. If it goes beyond this range, a large water exchange is recommended to restore balance and maintain a suitable environment for the shrimp. 5) Avoid stocking seedlings during heavy storms or adverse weather conditions. Sudden changes in water quality, strong currents, and fluctuating temperatures can harm the delicate young shrimp. Stocking Density The stocking density of shrimp seedlings should be determined based on several factors, including the water depth in the pond, the frequency of water exchange, the type and quantity of feed available, the size of the shrimp, and the skill level of the farm staff. As a general guideline, for 1-cm-long seedlings, the recommended stocking density is 1 to 1.5 million tails per mu. For 3-cm-old seedlings that are in the mid-cultivation stage, the density should be lower, around 0.7 to 1 million tails per mu. Proper stocking ensures optimal growth and reduces the risk of disease and overcrowding. Electronic Bluetooth padlocks represent a modern advancement in security technology, combining traditional locking mechanisms with smart wireless connectivity. These innovative locks utilize Bluetooth technology to enable convenient, keyless access control via smartphones or other Bluetooth-enabled devices. Designed for various applications, from securing lockers, cabinets, and storage units to gates and personal belongings, electronic Bluetooth padlocks offer enhanced security features compared to conventional mechanical locks. One of the key benefits of electronic Bluetooth padlocks is the ability to manage and share access permissions remotely. Users can grant or revoke entry rights instantly through a dedicated mobile app, eliminating the need to distribute physical keys or combinations. This feature is particularly useful for businesses, gyms, rental properties, and shared facilities where multiple users require access at different times. Most Bluetooth padlocks incorporate robust encryption protocols to prevent unauthorized access and hacking attempts. The locks typically include tamper alarms and automatic locking functions that activate after a set period or when the lock is moved forcibly. Some models also offer audit trails, logging every access attempt with timestamps, enabling users to monitor who accessed the lock and when. The construction of these locks often features weather-resistant materials such as stainless steel or hardened alloy, making them suitable for both indoor and outdoor use. Many electronic Bluetooth padlocks come with rechargeable batteries that provide months of operation on a single charge. In case of battery depletion, some devices include backup power options or mechanical override keys for emergency access. Installation is generally straightforward, as Bluetooth padlocks mimic the form factor of traditional padlocks and do not require complex wiring or infrastructure changes. The mobile apps designed for these locks are usually intuitive, offering features like multi-user management, temporary or scheduled access, and notification alerts for suspicious activities. Overall, electronic Bluetooth padlocks represent a significant step forward in secure, flexible, and user-friendly locking solutions. They are ideal for individuals and organizations seeking smart security options that blend convenience with advanced technology. Whether protecting personal valuables, securing commercial assets, or controlling access to shared spaces, Bluetooth padlocks deliver reliable protection with modern connectivity advantages.

1) The water depth in the rearing pond should be maintained between 40 to 70 cm. The water should be rich in nutrients, with a transparency of 30 to 40 cm to ensure good visibility and healthy growth conditions for the shrimp.
