Fry breeding intelligent production system


Fry breeding intelligent production system

  Global marine fisheries are gradually depleting, and aquaculture fisheries are rising. At present, global aquaculture production is increasing at an annual rate of 8%, and 90% of them are concentrated in Asia (FAO, 2016). The aquaculture industry in Taiwan is also one of the important basic agriculture, but its production has been stagnating at 300,000 tons many years (F.A., 2020) and there has been no breakthrough in the development of fry breeding technology. The main reason is that the aquaculture industry in Taiwan is mostly extensive and small-scale. The related breeding procedures and environmental management information are difficult to inherit, which is not conducive to product management and resume tracking and makes improvement and progress extremely difficult. Therefore, guiding aquatic technology toward automation, intelligence, and leading inheritance are the main tasks of the intelligent fry production system.

  The core of the system takes modularization, standardization and multi-function as the main concepts. It uses programmable logic controller for decision-making and connection of the intelligent breeding system. It connects various valves, sensors, controllers, computers and other systems through various interfaces, which have the advantages of low failure rate and high reliability, and combines with peripheral equipment such as artificial intelligence, Internet of Things, machine learning and other technologies. It can fast and simply add or replace various modules without costly modifications to the system and keep pace with the modern technology.

  The peripheral systems contain the micro-organism observation system that is used to observe the length and width of the fry through stereo vision, the plate-type biometric device which can provide accurate biological data and make decision for culturing of live-food organisms, and quantitative suction device to provide accurate feeding. The control of the system can be carried out at the remote end and cross-platform to achieve a completely unmanned design. Compared with traditional artificial breeding, the current experimental results of fry harvest have reached 3.85 times and 2.38 times in giant grouper and orange-spotted grouper and achieve a stable breeding condition.

  By breeding in the intelligent way with various modules, the intelligent fry production system can reduce the manpower requirement and achieve the goal of saving costs and stabilizing the output. It is expected to save 60% labor, 40% production cost, improve fry growth rate through big data compared with traditional farming, and form a complete intelligent production chain with the adult fish intelligent breeding system. It is helpful for the overall output value of aquaculture industry in Taiwan and the policy promotion of Smart Farming.
