“…Studies performed in fish showed that shorter wavelengths (blue and green) can promote larvae growth performance in Atlantic cod (Gadus morhua), turbot (Scophthalmus maximus), and European sea bass (Dicentrarchus labrax) (Villamizar et al, 2009;Sierra-Flores et al, 2016). In crustaceans, enhanced growth was reported in the giant freshwater prawn (Macrobrachium rosenbergii) when exposed to green as opposed to red light (Wei et al, 2021). However, specific growth rate (SGR) was enhanced in the Chinese shrimp Fenneropenaeus chinensis reared under natural light while SGR was suppressed under blue light (Wang et al, 2003).…”

An 8 weeks trial was performed to test the effects of light spectra [full-spectrum, violet (405 nm), blue (470 nm), cyan (500 nm), green (525 nm), yellow (570 nm), and red (625 nm)] on growth performance, molting, antioxidant capacity, stress response and expression of molting, and apoptosis-related genes in Scylla paramamosain. Results showed that spectrum had a significant effect on S. paramamosain physiology. Compared to blue light, crabs exposed to violet light had a significantly lower survival rate (79.5 ± 3.6% vs. 94.9 ± 3.6%), weight gain (49.2 ± 5.4 vs. 67.6 ± 6.7), molt frequency (4.2 ± 0.2 vs. 4.5 ± 0.1), and extended intermolt intervals between instar 1 and 2 stages (C1–C2) (6.3 ± 0.3 vs. 5.0 ± 0.1 days). Expression of the molt-inhibiting hormone (mih) gene was upregulated in crabs reared under violet light. According to the regression analysis, maximum SGR would be at 449.97 nm. Crabs exposed to blue light also had lower melatonin levels than under full-spectrum and lower cortisol levels than violet and yellow groups. Regarding oxidative stress, crabs in full-spectrum had lower H2O2 and MDA contents, however, no significant difference was found in total antioxidant capacity (T-AOC), superoxide dismutase (SOD), and catalase (CAT) in hepatopancreas from crabs under different spectra. Gene expression of hsp40, hsp70, hsp90 were down-regulated in crabs exposed to the full-spectrum light group. Regarding apoptosis-related genes, bcl-2 gene expression in crabs under cyan and the cox IV and caspase 3 in green were upregulated, suggesting cyan light may inhibit, while green light may promote apoptosis. Taken together, these results suggest that blue or cyan light would promote growth performance, while full-spectrum light could reduce stress response in S. paramamosain.

“…The Engineering Park has a modular closed-loop water supply system, which allows you to keep enough shrimp for a statistically significant sample. According to the experiment plan, there are 2 input parameters: water quality and feed type and 2 output parameters: growth rate and survival rate [9]. Additionally, the nutritional content of the meat was evaluated.…”

The aim of the study is to determine the effect of the feed type (Daphnia pulex-based feed and Dajana nano gran brand) on the water quality (presence of microorganisms and suspended solids) and on the growth and survival of Macrobrachium rosenbergii shrimp larvae. The study implementation plan involved 4 groups of shrimps placed under the same conditions, which were evaluated for 14 weeks through periodic observations and biometrics. The data obtained recorded significant differences between the groups where the best growth and survival results were obtained in organisms that received Dajana nano gran feed, regardless of water quality. In addition, the values of protein in shrimp meat up to 45% and different amounts of fatty acids were obtained. It was determined that the Daphnia pulex-based feed showed lower results in the growth rate and survival rate of Macrobrachium rosenbergii shrimp.

“…Salinity is a vital environment factor that affects survival, growth, and distribution of many aquatic organisms and mainly affects the physiology of various aquatic animals [1,2]. Under salinity fluctuations, some of the aquatic animals required more energy to adjust the osmotic pressure balance between their body fluid and the environment [3,4].…”

Salinity is one of the important environmental factors affecting survival and growth of aquatic animals. However, the impact of low-salinity stress on M. rosenbergii post-larvae at different development stages remains elusive. Therefore, the aim of this study was to explore the underlying mechanisms of hypotonic stress at different development stages of M. rosenbergii post-larvae through transcriptome analysis and antioxidant parameters detection. The salinity of the control group was 15 psu (S15) and the hypotonic stress group was 6 psu (S6). Samples were collected at 7 days-post-hatch (dph), 14 dph and 21 dph larvae. The results showed that hypotonic stress caused oxidative damage in post-larvae evidenced by decreased glutathione peroxidase (GSH-Px); superoxide dismutase (SOD); anti-superoxide anion free radical (ASAFR); and increased malondialdehyde (MDA); nitric oxide (NO); and inducible nitric oxide synthase (iNOS) levels. Transcriptome analysis showed that there were 1428, 1187, 132 DEGs including 301, 366, 4 up-regulated genes and 1127, 821, 128 down-regulated genes at 7 dph, 14 dph and 21 dph larvae under hypotonic stress, respectively. Furthermore, GO and KEGG enrichment indicated that hypotonic stress led to dysregulation of immune signals including lysosome and autophagy in the 7 dph larvae. The autophagy-related genes including beclin 1-associated autophagy-related key regulator (Barkor); ubiquitin-like modifier-activating enzyme ATG7 (ATG7); Beclin; autophagy-related protein 13 (ATG13); nuclear receptor-binding factor 2 (Nrbf2); ubiquitin-like-conjugating enzyme ATG3 (ATG3); vacuole membrane protein 1 (VMP1); and autophagy-related protein 2 (ATG2) decreased at 7 dph, and 14 dph larvae, and then increased at 21 dph larvae under hypotonic stress. In the 14 dph and 21 dph larvae, the renin-angiotensin system was activated. In conclusion, our data indicated that hypotonic stress reduced the antioxidant capacity and impaired the immune system in post-larvae, but as development progresses, the adaptability of post-larvae to hypotonic stress gradually increased, and might reach a new homeostasis through the RAS signaling pathway.
