Previous studies have also shown that themetabolic energy had the
largest share in the energy distribution of decapoda crustaceans. Therefore,
the change of metabolic energy could determine the energy accumulation
for growth (Paul and Akira, 1989;Wang et al., 2005). Le Reste
(1970) reported that blue lightwas able to induce locomotor activity in
Fenneropenaeus indicus and more energy was allocated for respiration
when the shrimps were under the blue light.
