| Abstract: |
The paper describes the phototactic types of fishes in the photogradient.The phototactic behaviour depends not only on the strength of illumination, but also on the wavelength of various light.Influence of moonlight was also investigated.It is found that the degree of inhibition depends on the relative intensity between background light and stimulating light and on the phototactic character of fishes.Finally, a theoretical analysis for phototactic behaviour of fishes is suggested.
Basic research on the phototactic behaviour of fishes is not only significant for understanding the influence of light on fish behaviour, but also has implication for production. |
