Abstract
Description
Technical Field
[0001] This utility model relates to a fishpond system, and more particularly to a modular fishpond system constructed using containers arranged in a ring around the fishpond and combined with an intelligent management system. Background Technology
[0002] Traditional aquaculture typically uses conventional fishponds, constructed from cement or soil. These ponds are not only expensive to build, but once completed, their shape, size, or location is difficult to change to suit specific needs, severely limiting the flexibility of the aquaculture site. Expanding or reducing the scale of aquaculture often requires large-scale engineering modifications, consuming significant amounts of money and time.
[0003] In fish farming, farmers need to regularly check water quality, feed the fish, and maintain appropriate water temperatures. These tasks require a significant amount of human resources, resulting in low efficiency and the tedious monitoring work is prone to errors due to human negligence. Traditional water quality management in aquaculture ponds often relies on manual, periodic sampling and testing, which cannot reflect real-time changes in water quality. By the time water quality problems are discovered, the fish may have already been harmed. Temperature control typically relies on natural air temperature or simple heating equipment, making it difficult to precisely control the water temperature within the optimal range for fish growth. Feeding is mostly estimated manually, which can easily lead to overfeeding causing water pollution or underfeeding affecting fish growth. All these problems reduce farming efficiency and fish survival rates.
[0004] While existing aquaculture technologies incorporate some intelligent applications, most improvements focus on single functions, such as automatic feeding systems or water quality monitoring systems. These often fail to form an integrated intelligent solution, as the systems operate independently and struggle to collaborate, hindering data sharing and comprehensive decision-making. Furthermore, harvesting typically requires significant manpower, which is inefficient and disruptive to the pond environment, impacting the growth of unharvested fish. Subsequent processing, such as cleaning, processing, and freezing, necessitates additional facilities and equipment, increasing transportation and time costs. Environmental changes during transport can also affect product quality, ultimately reducing the overall economic benefits of aquaculture. Utility Model Content
