With the continuous improvement of people's living standards in our country, the demand for live fish sales has been steadily increasing. As a result, the live fish transportation industry is facing growing challenges and opportunities. While traditional methods of transporting live fish vary in terms of container design and transportation tools, they all share a common goal: maintaining sufficient oxygen levels to ensure the survival of the fish during transit. Techniques such as circulating water systems, oxygen cylinders, and chemical oxygen release are commonly used to increase dissolved oxygen in the transport water.
However, during transportation, fish are often kept in highly concentrated, confined spaces, making it difficult to maintain optimal oxygen conditions. Additionally, the movement and vibrations from transportation vehicles can cause stress and agitation in the fish, leading to increased metabolic activity. This not only raises their oxygen consumption but also increases the production of waste products like carbon dioxide and ammonia, which can pollute the water and further threaten the fish’s survival. Therefore, reducing the environmental demands on the fish during transit is crucial for successful live fish transportation.
One effective method that has gained popularity is the use of sedative drugs in live fish transport. By adding specific chemicals to the transport water, the fish are induced into a state of reduced activity and slowed physiological responses. These sedatives help the fish remain calm, move less, and lower their metabolic rate, thereby decreasing oxygen consumption and waste production. This "resting" strategy allows fish to survive longer in limited space. Once the transport is complete, placing them back into clean water helps them recover quickly and return to normal behavior.
The sedative-assisted live fish transportation method offers several advantages, including higher survival rates, greater transportation density, extended travel times, ease of operation, and lower costs. It does not require special equipment or complex management, making it an attractive option for the fishing industry. In recent years, this technique has been increasingly adopted and valued due to its efficiency and effectiveness in ensuring the safe delivery of live fish.
