“…However, Hoang et al (2002a, b) believed that the molting frequency of P. merguiensis broodstock appeared to be stimulated by strong light intensity. Some authors believed that more frequent molting under stronger light intensity was related to molt-stimulating hormone (MSH) synthesis activity or other metabolism-related hormones (such as the crustacean hyperglycemic hormones (CHH) family, mainly secreted from the eyestalk; Hoang et al 2003). However, in this study, molting frequency in group LL was almost the same as that in group NL, but the light intensity in group LL was dimmer than that in group ML.…”

“…Gardner and Maguire (1998) suspected that the shorter molting interval of Australian giant crab larvae at a higher light intensity (500 lx) was possibly caused by increased feeding, but they also pointed out that brighter light (500 lx or more) was not necessary for optimal feeding. Hoang et al (2003) found that prawns cultured at 750 lx consumed less feed compared with those cultured at 75 lx. In the present study, the crabs were excessively fed, since the digestive enzyme (trypsin and pancreatic lipase) was Data presented are means ± SE.…”

“…Similarly, Hoang et al (2003) reported that light intensity had no significant effects on molting frequency or molting interval of Penaeus merguiensis. Gardner and Maguire (1998) also found Australian giant crab larvae reared in brighter light (500 lx vs 2 lx) had shorter intermolt duration.…”

“…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.

“…También es conocido el hecho que la intensidad de luz afecta la intensidad de color en decápodos (Hung-Pan et al, 2001;Hoang et al, 2002Hoang et al, , 2003, pero este fenómeno no está tan extensamente estudiado y está documentado para camarones marinos donde se ha encontrado que ciertas intensidades de luz favorecen el crecimiento en tanto que otras lo inhiben (Wang et al, 2004).…”

RESUMEN.Macrobrachium tenellum es un langostino dulceacuícola que destaca por su capacidad de cambio en función de diferentes estímulos. Para determinar el efecto de diferentes intensidades de luz sobre la expresión de cromatóforos, crecimiento y supervivencia, se sometieron langostinos juveniles (28.60-28.97 mm) a cuatro tratamientos 30, 600, 1500 y 3500 lux, durante 45 días. Al final de experimento se determinó el crecimiento en talla y peso, cantidad de alimento consumido, factor de conversión alimenticia y supervivencia. El análisis de la expresión de cromatóforos se efectuó mediante su conteo a partir de fotos del tercer somita y exopoditos de los urópodos. El crecimiento en peso y talla de los organismos sometidos a las diferentes intensidades de luz no mostró diferencias significativas entre tratamientos (P > 0,05). El consumo total de alimento, factor de conversión alimenticia y supervivencia tampoco resultaron con diferencias significativas. Respecto de la cantidad de cromatóforos hubo diferencias entre tratamientos, las dos intensidades menores de luz y las dos mayores intensidades de luz fueron diferentes, a mayor intensidad de luz mayor número de cromatóforos expresados.

Effect of different light intensities on expression of chromatophores, growth and survival in juvenile Macrobrachium tenellumABSTRACT. Freshwater prawn Macrobrachium tenellum is noted for its ability to change color depending on different stimuli. In order to determine different light intensities on the chromatophore expression, growth and survival, juvenile shrimps (28.60-28.97 mm) were subjected to four treatments 30, 600, 1500 and 3500 lux for 45 days. At the end of the experiment the growth in size and weight, amount of food consumed, feed conversion and survival were determined. The expression analysis of chromatophores was performed by its count from photos of the third somite and the uropod exopodite. Growth in height and weight of prawns subject to the different light intensities showed no differences between treatments (P > 0.05). The total consumption of food, feed conversion and survival showed no significant differences. In relation with the number of chromatophores, differences between treatments were evident; lower light intensities were different to higher ones. The higher light intensity increased the number of expressing chromatophores.

This study aimed to investigate the effects of red, yellow, green, violet, blue, and white light in Macrobrachium amazonicum larviculture. The trials were composed of six treatments (i.e., colors red, yellow, green, blue, violet, and white light in tanks) with four replicates each. Transparent tanks of 1 L of water, 10 salinity, and 2400 newly hatched larvae were used in trials. The larvae were fed Artemia salina nauplii and complemented with commercial shrimp feed daily. The light color affected the temperature, pH, and dissolved oxygen in the water culture and nauplii consumption, survival, and productivity of M. amazonicum. In the tanks with red light, the mean temperature was lower, while the oxygen and pH levels were higher than those with other colors. The mean consumption of A. salina nauplii was 15% higher by M. amazonicum in tanks with blue and violet light than red light. No difference in larval development was observed; however, larvae cultured under white light completed the larval cycle four days earlier than those cultured under red light. The productivity of larvae cultivated under white and violet light was 45% greater than larvae cultured under red light, and the survival was > 75%. Results indicated that M. amazonicum larval cultivation should be performed in tanks under bright light, preferably white, since other colors may negatively affect the larval development.
