There is, though, a relatively recent growth in interest in ‘fish twitching’, peeking into the rich underwater world that has often evaded wider public perception and appreciation. One strand of evidence for this includes the increasing profile of native fishes in television broadcasting. The patient observer, finding a suitable vantage point over still or flowing waters, is likely to be rewarded for their persistence looking through, rather than at, the surface film. This is significantly assisted by a good pair of polarising sunglasses that help vision cut through the surface glare. Generally, fish twitching is non-invasive, causing little or no disturbance. However, some precautions are necessary to ensure that the fish come to no harm. Fish do in some places, and can in others, form part of the tourism experience—for the casual or committed fish twitcher even if they have no angling interest—contributing to the tourism experience and economy.
