16 degrees celsius comes out to about 61 in fahrenheit.. I think that's pretty cold. I keep my bass at a "low" 21.1 degrees celsius during winter. Like Gangster said, just put them in with the water from the lake. I have no idea what's the weather like there but if it's hot, find a way to keep the water from getting too warm. If it's cold, the rate at which the temperature decreases in the transporting water should be pretty slow; it probably won't shock the fish.
