Abstract
There is something magical about it: making something visible that is largely invisible. A kind of metaphysics. Because one thing has not fundamentally changed since the ancient Greeks or Brother Sarmiento: throughout its entire lifetime tuna lives under water. What exactly it does there we barely know. This is not exclusively a problem with tuna but applies to all wild fish. It may be possible to make a more or less reliable estimate of the size of populations in a closed system such as that of freshwater fish in a lake. We can do something similar for groups of fish in the sea when we know that they live more or less entirely in fixed places around coral or in rocks.
