Why must the water flow rate be matched with fish size in raceways?

Matching the water flow rate with fish size in raceways is essential for preventing injury and stress caused by high flow rates. Fish, especially when they are smaller or younger, have less developed structures and weaker physical abilities. If the water flow is too strong, it can lead to physical harm, such as damaged fins or bodies from being tossed around in the current. Additionally, excessive flow can induce stress in fish, which can negatively affect their health and overall well-being.

Properly adjusted water flow rates help create an environment where fish can swim comfortably and access food without being overwhelmed by the current. This balance is crucial for fostering a healthy aquaculture system.

The focus on flow rates ensures that different sizes of fish receive the appropriate environmental conditions; larger fish might be able to handle stronger currents without suffering detrimental effects, while smaller fish could be easily overpowered. Balancing flow rates with fish size ultimately contributes to maintaining the integrity of the population and supports sustainable aquaculture practices.
