Physiological Responses of Golden Pompano Trachinotus ovatus Larvae Fingerlings in Transportation

The golden pompano Trachinotus ovatus has an outstanding farming performance and industrial advantages in aquaculture due to its great taste and short production cycles. At present, it has gradually become an important fish in aquaculture around the world. The transportation of golden pompano is a common but a vital component in its aquaculture production operation, especially for fingerlings. The success of fish transportation can affect the production cost to a large extent, which even directly determines the subsequent production profit. Generally, transportation in oxygenated polyethylene bags is the most common method. But in the transportation process from a hatchery to a fish grow-out farm, high mortality has been a serious problem. Up to present, there is no protocol for live transportation to follow based on scientific evidence on this species. Therefore, there is a strong need to know what happens to Trachinotus ovatus fingerlings in transportation, which means to understand the physiological responses of fish to water quality changes and stressors during transportation, so that we can determine optimal condition for the transport of live fish. In this chapter, we reviewed the results of previous studies on the physiological response of Trachinotus ovatus fingerlings to the transportation conditions and sought after the responding patterns of liver and serum biochemical parameters in fingerlings under transportation stress. Finally, we developed suitable protocols to optimize the transport success of Trachinotus ovatus fingerlings.
