| Iran's aquaculture industry has experienced significant growth in the last two decades, among which rainbow trout as the essential cold-water breeding species has particular importance and a high growth rate of production. Of course, this rapid increase in production has created problems and risks for this activity, which need better and principled management to solve them. Among the management factors that are ignored is the issue of transporting fish and eggs. Fish transportation activities, such as moving, trapping, and exposing to optimal water quality, can cause physiological changes in fish due to increased stress. In addition, understanding misplaced environmental conditions and how they affect fish often leads to new protocols that reduce stress and the risk of disease transmission. Among the principles of fish transport discussed in this study is the regulation of osmotic pressure, dissolved oxygen, suspended solids, ammonia, the temperature of the transport tank and its preservation, carbon dioxide, physical fishing, and drugs and Anesthesia noted. The stages of ocular egg transfer are also examined separately. Considering the importance of quarantine and its essential role in preventing the spread of infectious diseases, we have also examined its basic requirements and implementation levels. |
