Description

Technical Field

[0001] This utility model relates to the technical field of freshwater fish recirculating aquaculture equipment, and in particular to an integrated recirculating aquaculture equipment for the temporary holding of freshwater fish. Background Technology

[0002] With the increasing demand from consumers for high-quality aquatic products, freshwater fish, with their firm flesh and lack of muddy taste, are gradually becoming a new market favorite. Freshwater fish refers to adult fish that have been raised in ponds for a period of time and then temporarily raised in a clean water environment. By controlling feeding and increasing the fish's swimming activities, the fat and muddy taste substances in the fish are reduced, thereby improving the quality of the fish meat. During the temporary rearing process, water quality, dissolved oxygen levels, and water temperature play a decisive role in the survival rate and meat quality improvement of freshwater fish. Therefore, professional temporary rearing equipment has become the key to the industry's development. Thus, developing a freshwater fish temporary rearing equipment that integrates water purification, precise temperature control, efficient oxygenation, and intelligent monitoring functions, and is suitable for different farming scales, is an urgent need to solve the current pain points of the industry and promote the sustainable development of the freshwater fish industry.

[0003] Currently, recirculating aquaculture systems (RAS) on the market mainly consist of water circulation and treatment components and temporary holding components. Traditional freshwater fish temporary holding often uses open ponds or ordinary cement pools. These methods have many drawbacks: First, water quality is difficult to control precisely. Open water bodies are easily polluted by external sources, such as pesticide residues from surrounding farmland and industrial wastewater discharge, which not only affects the quality of freshwater fish but may also lead to disease and death. Second, water resources are wasted significantly. Because water cannot be recycled, frequent water changes are necessary, a problem particularly prominent in water-scarce areas. Third, there is a lack of systematic environmental monitoring and regulation equipment. Farmers cannot monitor key parameters such as water temperature, dissolved oxygen, and pH in real time, making it difficult to optimize the aquaculture environment. This results in long holding periods, low efficiency, and inconsistent fish quality. Although some RAS equipment exists on the market, there are few dedicated integrated systems specifically for freshwater fish temporary holding. Most existing RAS equipment has limited functions, only providing simple water filtration and oxygenation, which cannot meet the specific needs of freshwater fish temporary holding for water purification, precise temperature control, and simulated flowing water environments. Utility Model Content
