Slightly off topic:

Presumably the water in the truck stocking the tilapia is warmer than the pond water.

What is the procedure to release fish (any type) where the water in the tanks is at a different temperature than the water in the pond?

I have not seen a chart in the archives of the acceptable temperature difference for different species of fish. Does such a chart exist, or is there a rule of thumb that covers all of the most common species?

Thanks,
