Flow field simulation of aquaculture tank

Our laboratory is working on visualizing the flow in the culture tank using fluid simulation (CFD analysis) and visualization experiment (PIV experiment), with the aim of improving the breeding environment in the tank.
Complete aquaculture has the highest mortality rate in seedling production (from hatching to the larval stage), which has been a bottleneck for mass production.
It is known that fish at the larval stage are easily affected by the flow in the aquarium due to their low swimming ability and are prone to sinking death (a phenomenon in which they are damaged and die when hitting the bottom of the aquarium).
To prevent sinking death, the flow field in the aquarium must be set to avoid a sudden downward flow.
