“…Despite no significant difference in survival rates between the red-light and yellow-light groups, the average weight gain rate and total length gain rate within the red-light group were notably lower compared to those observed in the yellow and green-light groups. This may be due to the different durations of the two experiments; this study lasted 16 days longer than the experiment designed by Cheng et al [20]. Consequently, the continuous development of the compound eyes of crustaceans and their corresponding changes in sensitivity to different spectra and internal response mechanisms may occur, and the optimal light conditions for growth may also change accordingly [27].…”

“…Different crustacean species exhibit varying degrees of photosensitivity [23,24], which may be closely related to their environmental niches during different developmental stages [25][26][27]. Previously, Cheng et al [20] found that within 14 days post-hatching, juvenile redclaw crayfish exhibited higher survival rates under red light and experienced accelerated growth rates under blue light but demonstrated decreased survival rates and slower growth under green light [20]. However, findings from this investigation reveal that under yellow light spectrum cultivation conditions, the survival rate of juvenile redclaw crayfish was highest after 30 days posthatching, with a higher SGR.…”

“…Currently, research on how light affects newly hatched redclaw crayfish juveniles lasts only 14 days. Given that the factory-scale cultivation period for redclaw crayfish juveniles is approximately 30 days (with the total body length ranges from 3 to 5 cm), this research requires further refinement [20]. Hence, the objective of this study was to examine that five distinct spectral conditions impact the survival, growth performance, pertinent enzyme activity, and gene expression levels associated with the growth and development of juvenile redclaw crayfish during a 30-day rearing period.…”

The spectrum is a key environmental factor, and light-emitting diodes (LEDs) can influence the growth and development of crustaceans by altering the composition of the spectrum. This study conducted a 30-day experiment to investigate the effects of five LED spectra (red, yellow, blue, green, and white light) on the growth, antioxidant and immune enzyme activities, stress hormone levels, and the expression of α-amylase (α-AMY), ecdysone receptor (EcR) and retinoid X receptor (RXR) genes in juvenile redclaw crayfish (Cherax quadricarinatus). The results show that the survival rate of juveniles is markedly higher in the yellow and red-light groups than in the other three groups (P<0.05). The green light group exhibits the lowest survival rate, yet it demonstrates the highest weight gain rate and specific growth rate. Regarding enzyme activity and hormone levels, the yellow light group shows the lowest malondialdehyde content, with higher superoxide dismutase and acid phosphatase activity than the other groups; no significant differences are observed in lysozyme activity among the groups (P>0.05). The melatonin content in the green and blue light groups is significantly higher than that in the other three groups (P<0.01). In terms of growth gene expression, the expression of α-AMY, EcR, and RXR in juvenile C. quadricarinatus is regulated by the spectrum. In conclusion, when raised under the yellow light spectrum, juvenile C. quadricarinatus displays elevated survival rates, rapid growth, and robust antioxidant and immune defenses. This study provides important technical parameters for optimizing and enhancing the industrial cultivation of juvenile C. quadricarinatus.

“…Moreover, in crustaceans, the expression levels of α-AMY , MEF2a , GR , CHI , and EcR were closely associated with digestion and absorption, molting, and muscle production (Gao et al 2022 ; Zhang et al 2019 ). Specifically, molting is a periodic and energetically costly event regulated by EcR and CHI (Cheng et al 2023 ). MEF2a and GR were associated with muscle growth, while α-AMY was closely related to digestive and absorptive capacity and nutrient metabolism in crayfish (Zhang et al 2021 , 2023 ).…”

The intestinal microbiota interacts with the host and plays an important role in the immune response, digestive physiology, and regulation of body functions. In addition, it is also well documented that the intestinal microbiota of aquatic animals are closely related to their growth rate. However, whether it resulted in different sizes of crayfish in the rice-crayfish coculture model remained vague. Here, we analyzed the intestinal microbiota characteristics of crayfish of three sizes in the same typical rice-crayfish coculture field by high-throughput sequencing technology combined with quantitative real-time polymerase chain reaction (qRT-PCR) and enzyme activity, investigating the relationship between intestinal microbiota in crayfish and water and sediments. The results showed that the dominant intestinal microbiota of crayfish was significantly different between the large size group (BS), normal size group (NS), and small size group (SS), where Bacteroides and Candidatus_Bacilloplasma contributed to the growth of crayfish by facilitating food digestion through cellulolysis, which might be one of the potential factors affecting the difference in sizes. Follow-up experiments confirmed that the activity of lipase (LPS) and protease was higher in BS, and the relative expression of development-related genes, including alpha-amylase (α-AMY), myocyte-specific enhancer factor 2a (MEF2a), glutathione reductase (GR), chitinase (CHI), and ecdysone receptor (EcR), in BS was significantly higher than that in SS. These findings revealed the intestinal microbiota characteristics of crayfish of different sizes and their potential impact on growth, which is valuable for managing and manipulating the intestinal microbiota in crayfish to achieve high productivity in practice. Key points • Significant differences in the dominant microflora of BS, NS, and SS in crayfish. • Cellulolysis might be a potential factor affecting different sizes in crayfish. • Adding Bacteroides and Candidatus_Bacilloplasma helped the growth of crayfish.

“…The rhythmic secretion of melatonin by Chinese mitten crab (Eriocheir sinensis) and the crab (Neohelice granulate) can be disrupted under constant light conditions [15,18]. Furthermore, as a stressor, drastic changes in photoperiod can cause crustaceans to produce a series of responses, which cause variations in reactive oxygen species (ROS) levels and lead to oxidative stress and negative impacts [16,19]. Cortisol is an essential indicator of internal environmental stability in crustaceans.…”

Through a 30-day experiment, this study investigated the effects of five photoperiods (0L:24D, 6L:18D, 12L:12D, 18L:6D, and 24L:0D) on the survival, enzyme activity, body color, and growth-related gene expression of redclaw crayfish (Cherax quadricarinatus) juveniles. The results showed that C. quadricarinatus juveniles under 18L:6D and 24L:0D photoperiods exhibited the highest survival rate, which was significantly higher than the survival rates of juveniles under the other three photoperiods (p < 0.05). However, the 0L:24D group had the highest final body weight and weight gain rate, significantly surpassing those of the 12L:12D, 18L:6D, and 24L:0D groups (p < 0.05). Regarding enzyme activity and hormone levels, juveniles under the 18L:6D photoperiod exhibited relatively higher activity of superoxide dismutase (SOD), acid phosphatase (ACP), and lysozyme (LZM) enzymes than those under other photoperiods, but their levels of melatonin and cortisol were relatively low. In addition, the 24L:0D group showed the highest malondialdehyde (MDA) content. Analysis of gene expression levels revealed that retinoid X receptor (RXR) and α-amylase (α-AMY) genes in C. quadricarinatus juveniles exhibited significantly higher expression levels under the 18L:6D photoperiod than those under the other four photoperiods (p < 0.05). With increasing daylight exposure, the body color of C. quadricarinatus changed from pale blue to yellow–brown. In summary, C. quadricarinatus juveniles achieved high survival rates, good growth performance, strong antioxidant stress response, and immune defense capabilities under an 18 h photoperiod. Therefore, in the industrial seedling cultivation of redclaw crayfish, it is recommended to provide 18 h of daily light. Further, the study demonstrated the ability to manipulate the body color of C. quadricarinatus through controlled artificial photoperiods. These findings provide essential technical parameters needed for the industrial cultivation of C. quadricarinatus juveniles.
