Abstract:

With the rapid development of the aquaculture industry, fry hatching, a critical stage in aquaculture, decisively influences both the quality and yield of fish. Traditional hatching methods face challenges such as poor water quality management, low hatching rates, and high labor costs, making them inadequate for modern high-density, intensive farming demands. This paper systematically introduces an automated recirculating water incubation system constructed with sensors, flow controllers, and heat pumps. By integrating key techniques like broodstock cultivation optimization and hormone injection experiments, the system achieves automated control in large-scale fry cultivation. Results demonstrate that the system significantly improves hatching rates and enables scalable fry production. Furthermore, it exhibits strong adaptability and stability in comparative hatching experiments across diverse fish species, including Ctenopharyngodon idellus, Opsariichthys bidens, Acrossocheilus parallens, and Saurogobio dabryi. The study confirms that this automated recirculating incubation system offers significant advantages in enhancing efficiency, reducing labor costs, and stabilizing water quality, indicating broad prospects for application and promotion.
