This will provide overall mixing and aeration. Want to locate the cage where it will have maximum available water movement. Pesticides are toxic to fish. Heavy amounts of manure can lead to dissolved oxygen problems. Water Quality Temperature Water temperature affects fish activity, behavior, feeding, growth, and reproduction.
Fish are cold-bloodied, and their temperature is approximately the same as their surroundings.
The temperature tolerances of common cage cultured species can be found in Table 1. Since fish take on the surrounding temperature, they cannot tolerate rapid changes in temperature. This becomes important when stocking and the container water temperature differs from the receiving pond water temperature. The recommended acclimation rate is for every 10 F change in temperature temper fish for 20 minutes. The cooler the water temperature, oxygen is more soluble.
