Which of the two pond sites is better suited for fish production? Why?
What will be an ideal response?
The optimal water for fish production varies according to the species of fish. Trout
and salmon need cold water in contrast to Tilapia and catfish, which prefer warmer
water. Trout and salmon prefer water with a higher dissolved oxygen content—
warmer water holds less oxygen than cooler water. Good light penetration indicates
a lower level of suspended solids in the water than poor light penetration. Fish do
not grow well in silty water. Suggest that your students work in small groups. Assign
each group a commercial species of fish to consider when answering the questions
in this lab exercise. Hopefully, your students will come to the conclusion that the two
sites that you have selected might be each suited for the production of a different
species of commercial fish.
