Solution Overview
Problem
Current methods for transporting live fish, such as anesthetic transport, electric shock, and cooling water tank transport, face issues like sanitary problems, high costs, uncertainty in physiological characteristics, and stress on fish, while conventional artificial hibernation methods struggle to maintain fish freshness and safety during long-hour transport.
Innovation Solution
A method involving gradual temperature reduction from an initial water temperature to an appropriate hibernation temperature, followed by a rapid decrease to the lowest temperature where fish swimming stops, combined with a container using potassium superoxide and gypsum to maintain internal temperature and supply oxygen, allowing fish to be packed in a waterless state for extended periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fish are transported using cooling water tank method, then fish can be kept alive during transport, but transport cost increases and fish may die during long-hour transport
Solution Approach 1:
The patent applies parameter changes by transitioning fish from active state to artificial hibernation state through controlled temperature reduction. Fish are gradually cooled from initial water temperature to hibernation temperature, fundamentally changing their metabolic state to reduce oxygen consumption and extend survival time without continuous water supply, thereby reducing transport costs while maintaining high survival rates
Solution Approach 2:
The patent enables fish to enter a self-maintaining hibernation state where their own physiological processes slow down sufficiently to allow survival without external water supply. The fish's reduced metabolic rate during hibernation allows them to sustain themselves on stored energy reserves, eliminating the need for continuous water provision and reducing transport infrastructure requirements
2Use of energy by stationary object
If plastic bag is used for waterless transport of hibernating fish, then distribution cost is reduced, but plastic bag may break at high altitude causing fish death
Solution Approach 1:
The patent applies beforehand cushioning by preparing fish for hibernation through gradual temperature adaptation before packaging. Fish are slowly cooled over several hours to acclimate their physiological systems to low temperatures, reducing thermal shock stress. This preparatory hardening makes them more resilient to environmental changes during transport, including pressure changes at high altitude, preventing sudden physiological failures that would cause death
3Speed
If water temperature is rapidly lowered to induce hibernation, then hibernation is induced faster, but fish experience cold shock increasing stress
Solution Approach 1:
The patent applies preliminary action by implementing a multi-stage temperature reduction process. Fish are first gradually cooled to an intermediate temperature, allowed to acclimate, then slowly cooled further to the final hibernation temperature. This staged approach prepares fish physiological systems progressively, preventing sudden thermal shock while still achieving hibernation induction within a practical timeframe
Solution Approach 2:
The patent implements periodic action through cyclic temperature adjustment phases: gradual cooling, stabilization period, further cooling, and final stabilization. Each phase allows fish to adapt to temperature changes before the next reduction begins. This periodic pattern of cooling and stabilization minimizes cumulative stress while ensuring complete hibernation induction

AI summary
The present invention relates to a method for inducing artificial hibernation of fish that is capable of transporting the fish in a state of being alive for long hours. According to the present invention, a water temperature is gradually decreased from an initial water temperature to the lowest water temperature, the fish are induced to the artificial hibernation, and they are packed in a waterless state. The packing is carried out in an environment where the lowest water temperature is constantly maintained, and a refrigerant is also packed to constantly maintain a temperature in a packing container, while oxygen is continuously supplied to the live fish induced to the artificial hibernation. The fish are individually packed in the Styrofoam box, and even if an atmospheric pressure in the airport is lowered during transport of the fish, there is no danger of causing respiration of the fish to be hard due to a plastic bag damaged. Through the hibernation inducing method and packing capable of reducing stress of the fish, in addition, the fish can be alive in a waterless environment for 36 hours or more, thereby making possible to globally distribute the live fish.
