FISH CAN SEE IN COLOUR

Angling Times (UK) - - UNDERWATER SPECIAL -

DO fish see dif­fer­ent colours the same as we do? Coarse fish have the same light-re­ac­tive cells in their eyes as hu­mans, so they can see colours, although they might per­ceive them slightly dif­fer­ently us. More im­por­tantly, though, coloured baits re­ally do stand out against the gen­er­ally brown lake bot­tom or riverbed.

In very deep water, say more than 20ft, colours at the red end of the spec­trum are lost as these wave­lengths of light are ab­sorbed by the water. Shal­lower than this, though, colours stand out well.
