THE FEEDING INTENSITY OF FAT GREENLING LARVAL UNDER DIFFERENT ILLUMINATION

This paper deals with the feeding intensity,feeding rate and feeding dynamics of fat greenling larval under different illuminations.The feeding intensity was greatly influnced by light intensity.Under the light intensity between 100 and 10?Lx,the feeding intensity was relatively high.Under the strong light of 10?000?Lx,the feeding intensity is low.Then it began to increase with the weakening of illumination and reaches maximum under 100?Lx.Then it decreased with the continued weake\|ning of light intensity and reached the minimum under 0 1?Lx.Under the conditions of this experiment,100?Lx is the optimum illumination for feeding.
