“…In general, studies demonstrating the influence of light on feeding rates and metabolism in crustaceans are rare. Fanjul-Moles et al (1998) demonstrated the effect of light on the neural and endocrine structures responsible for the control of behavior and metabolic functions of crayfish during exposure to different photoperiods and light intensities. However, several studies have indicated the relevance of light duration and intensity on diverse other biological processes in crustaceans (Gardner and Maguire 1998;Otero et al 1998;Hoang et al 2003).…”

The effect of different light regimes on physiological parameters (feeding activity, oxygen consumption, and activity of the metabolic enzyme malate dehydrogenase [MDH]) of Antarctic krill, Euphausia superba, was studied over 12 weeks under laboratory conditions. Krill were exposed to light-cycle regimes of variable intensity to simulate Southern Ocean summer, autumn, and winter conditions, respectively, using: (1) continuous light (LL; 200 lux max), (2) 12-h light and 12-h darkness (LD 12 : 12; 50 lux max), and (3) continuous darkness (DD). In all experimental groups, the food concentration was kept at high levels (, 800 mg C L 21 ). Krill exposed to LL and LD 12 : 12 showed an increase in all measured parameters over the experimental period. Physiological parameters of krill held under LD 12 : 12 showed a more consistent increase and remained below those of krill held under LL. No change was recorded for krill exposed to DD; clearance rates and daily C rations did not respond to the high food availability, and oxygen consumption rates and MDH activity were significantly lower (p , 0.05) than those of krill exposed to summer light condition. Thus, changes in the environmental light regime have an important effect on physiological parameters of krill, such as feeding and metabolic rates, and may indicate an inherent overwinter adaptation strategy triggered by the Antarctic light regime.

“…Long days shorten the time between molts, which produce lower biomass incorporation due to the high cost of energy that the molt implies. An increase of photoperiod length produces an increase in haemolymph of lactate similar to that produced by exercise and other factors considered as stressors in decapod crustaceans (FANJUL-MOLES et al, 1998). Palaemonetes argentinus is not very aggressive and the density in the aquaria was quite low to avoid cannibalism on individuals which had recently moulted.…”

“…Some studies have compared the effect of constant conditions with the daily light-dark cycles, with variable results (DALLEY, 1980). Artificial light is used as a tool, in species adapted to diverse environments and at different latitudes, to investigate the physiological dynamics which could be involved in determining distribution and adaptation patterns of these animals (FANJUL-MOLES et al, 1998). The daily cycle of light and dark, and the seasonal changes in the proportions of light-dark are most likely to be of significance in the crustacean life (DALLEY, 1980).…”

Growth, survival and molting rate in Palaemonetes argentinus Nobili, 1901 were compared under different light-dark conditions. During 80 days, 150 immatures of both sexes (initial mean weight 0.09±0.002g), from Los Padres lagoon, Mar del Plata, Argentina, were maintained in aquaria at 19±0.4°C under three light conditions: 0:24, 10:14 and 13:11 (L-D). They were fed daily on an artificial diet (45% proteins, 17.2% lipids, 7% water, 7% ash). Good weight increment was obtained with the three treatments, finding a positive linear correlation between mean weight and time (0:24, r=0.97; 10:14, r=0.99; 13:11, r=0.98). There were no significant differences in the percentage increment in mean weight among the treatments (0:24, 19.3%; 10:14, 29.3% and 13:11, 26.5%) (p<0.05). Molting rate was significantly higher at a long-day photoperiod (MR=1.7) than at a shortday (MR=0.6) or continuous dark condition (MR=0.3) (p<0.05). The lowest survival was found in animals maintained under 13:11 L-D conditions (77%), being statistically different of the other two treatments (92% and 89% at 10:14 and 0:24, respectively) (p<0.05). These results suggest that the best growth and survival in P. argentinus result with a 10:14 L-D cycle, and that the growth is less affected by photoperiod than molting rate and survival.

“…The effects of light intensity have been studied on molting and growth (Vijayan and Diwan 1995;Hoang et al 2003;Wang et al 2004), maturation (Hoang et al 2002a, b) and activity (Wassenberg and Hill 1994;Fanjul-Mole et al 1998) in prawns or shrimps, but very few studies have investigated the effects of light intensity on the growth, survival, or behavior of crabs (Gardner and Maguire 1998;Vannini et al 1995;Rabbani and Zeng 2005;Epelbaum et al 2007). Furthermore, most studies related to light effect were carried out at a constant light intensity or photoperiod, which was different from natural conditions.…”

A 74-day growth trial was carried out to investigate the effects of light intensity on the juvenile Chinese mitten crab, Eriocheir sinensis, under semi-natural conditions. The experiment had three light intensity treatment groups, natural light (NL), middle light (ML), and low light (LL), as light intensity became weaker. The results indicated that light intensity had no significant effect on molting interval and molting frequency but did have a significant effect on the molting weight gain of the crab. Molting weight gain in group NL was significantly higher than that in group LL (P \ 0.05). Specific growth rate in weight (SGRw) and in carapace width (SGRcw), weight gain, and final body weight were significantly affected by light intensity (P \ 0.05). No significant difference was detected in survival between groups (P [ 0.05). The precocious rate in groups NL, ML, and LL was 26.14, 15.48, and 17.14%, respectively. The precocious rate in group NL was significantly higher than that in groups ML and LL (P \ 0.05). Chemical composition of the crab body was significantly affected by light intensity, but the activity of alkaline phosphatase, trypsin, and pancreatic lipase was not significantly affected by light intensity. The results indicated that the submitted light intensity was useful in reducing the precocious rate without affecting the normal growth of juvenile E. sinensis.
