Waiting for a frost


Researcher Hans Verdaat is standing in the middle of a boat full of fish. They are sprats and about 3,000 kilos were caught in ten minutes.

'A big catch,' says Verdaat. Imares is doing research on the numbers of grebes along the northern Dutch coast. Grebes feed mainly on fish. So the aim of this expedition is to get an idea of fish stocks. Verdaat hopes then to be able to see the relation between the distribution of the birds and of their food supply. The researchers have been waiting months for a severe frost so that they could study the situation under wintry conditions.
