The design and operation of a grid-net are described, which allows the capture of entire shoals of wild fish and preserves information about the two-dimensional structure of shoals and the spatial positions of individual fish within the shoal. This simple technique facilitates investigation of several aspects of individual differences in fish shoaling behaviour in the wild for the first time.
