“…Seventeen isonitrogenous (crude protein 37%) and isolipidic (crude lipid 7.5%) diets were produced: a control diet (free‐supplementations) and 16 experimental diets that added with four levels of five different supplementations as follows: Vit E (40, 160, 240 & 320 mg/kg); NT (2, 4, 6 & 8 g/kg); H. pluvialis (2, 4, 6 & 8 g/kg); ARA (5, 10, 15 & 20 g/kg); YP (2.5, 5, 10 & 15 g/kg) using orthogonal array design method (L16 [4 5 ], [Table 1]) according to Shehata et al (2020). The formulation and nutrient composition of experimental diets and supplementation levels are shown in Tables S1 and S2.…”

“…Aeration was supplied to each tank for 24 h per day, and the photoperiod was maintained at 14 h light: 10 h dark with fluorescent lights controlled by electric timers. All the previous processes we have mentioned, according to Shehata et al (2020). All crayfish handling and sampling, plus the experimental protocols used in this project, were approved in advance by the University of FAFU Institutional Animal Care and Use Committee (IACUC).…”

An optimal diet is an important factor for the proper growth and health of crustaceans. However, the regulation of antioxidant activity and non-specific immunity related to the consumption of feed additives has not been studied in RC-crayfish. Triplicate groups of 20 crayfish/tank (36.72 ± 0.70 g) fed with a basal diet and sixteen experimental diets that contained five feed additives with four grade levels (40, 160, 240 and 320 mg/kg vitamin E, 2, 4, 6 and 8 g/kg nucleotides, 2, 4, 6 and 8 g/kg Haematococcus pluvialis, 5, 10, 15 and 20 g/kg arachidonic acid and 2.5, 5, 10 and 15 g/kg yeast extract) on physiological parameters, fatty acids profile and growth of Cherax quadricarinatus for a period of 70 days by using orthogonal array method (L16 4 5 ). The results showed that the antioxidants activity in the haemolymph and hepatopancreas were both higher in crayfish fed with diets NO. 9 to 12 than others. Also, all the diets except diets NO. 13 to 16 showed lower free radicals contents than the control group. Similarly, significantly higher nonspecific immune parameters were observed in the hepatopancreas of crayfish supplementations than those fed a control diet. Biochemical parameters related to protein profile in haemolymph increased in diets NO. 9 to 12 and then decreased in control and diets NO. 13 to 16, while the highest biochemical parameters related to lipid profile except HDL-c contents in haemolymph were observed in crayfish fed the control diet. Fatty acid composition in the hepatopancreas, muscle and ovary of RC-crayfish was significantly influenced by using the combination of Vit E, NT, H. pluvialis and YP compared to the control group. Compared to all treatments, RCcrayfish fed with diets NO. 2 and 12 had significantly stimulated higher growth performance and feed utilisation. Overall, our results suggest that diets supplemented with Vit E level of 240 mg/kg, in combination with 8 g/kg NT, 4 g/kg, H. pluvialis, 5 g/kg ARA and 10 g/kg YP are the promising treatments to increase antioxidants activity, non-specific immune response, fatty acids composition and growth of RC-crayfish. However, high dietary supplementations level can reduce antioxidants activity, immunity and inhibit growth.

“…The orthogonal array design, theory, and method is a modern time-and cost-effective research technique constructing an orthogonal array to classify regions where varieties may be successfully reduced (Ross, 1996), like the previously experiments have done in plants (Elmardy et al, 2021;Liang et al, 2021;Hamedalla et al, 2022) and animals (Shehata et al, 2020(Shehata et al, , 2022. Furthermore, the interaction effects between factors can be treated as autonomous factors and evaluated using the triangular table in relation to the associated orthogonal array preserving the advantages of the traditional fractional factor design (Cortés-Jacinto et al, 2005;Shehata et al, 2022).…”

Due to advances in the industrial development of light-emitting diodes (LEDs), much research has been conducted in recent years to get a better understanding of how plants respond to these light sources. This study investigated the effects of different LED-based light regimes on strawberry plant development and performance. The photosynthetic pigment content, biochemical constituents, and growth characteristics of strawberry plants were investigated using a combination of different light intensities (150, 200, and 250 μmol m−2 s−1), qualities (red, green, and blue LEDs), and photoperiods (14/10 h, 16/8 h, and 12/12 h light/dark cycles) compared to the same treatment with white fluorescent light. Plant height, root length, shoot fresh and dry weight, chlorophyll a, total chlorophyll/carotenoid content, and most plant yield parameters were highest when illuminated with LM7 [intensity (250 μmol m−2 s−1) + quality (70% red/30% blue LED light combination) + photoperiod (16/8 h light/dark cycles)]. The best results for the effective quantum yield of PSII photochemistry Y(II), photochemical quenching coefficient (qP), and electron transport ratio (ETR) were obtained with LM8 illumination [intensity (250 μmol m−2 s−1) + quality (50% red/20% green/30% blue LED light combination) + photoperiod (12 h/12 h light/dark cycles)]. We conclude that strawberry plants require prolonged and high light intensities with a high red-light component for maximum performance and biomass production.

“…Red claw crawfish ( Cherax quadracarinatus ) is a wide‐temperate and moderately salty crustacean native to northern Australia. Due to its wide environmental tolerance and capability of growing at high stocking densities (Ghanawi et al, 2019; Shehata et al, 2022), red claw crayfish can easily establish populations in different habitats and has been extensively introduced to many regions for aquaculture worldwide (Shao et al, 2017; Shehata et al, 2020). Based on the recent survey of the FAO (2020), red claw crayfish is now the second most cultured crayfish species globally and has become a prominent aquaculture species with high economic impact.…”

A 60‐day feeding trial was conducted to evaluate the effects of yellow mealworm (YM) (Tenebrio molitor) (9%, 18%, 27% and 36%) and black soldier fly larvae (BSFL) (Hermetia illucens) (7%, 14%, 21% and 28%) meal replacing fish meal (FM) on growth performance and antioxidant capacity of red claw crayfish (Cherax quadricarinatus). Nine diets, including control, were fed with quadruplicate of 20 crayfish (0.20 ± 0.05 g). The highest weight gain (WG) and lowest feed conversion ratio were observed in crayfish fed YM18 and BSFL14. The highest superoxide dismutase activity and the lowest malondialdehyde content were detected in the hepatopancreas of the crayfish fed YM18 and BSFL14. Compared with the control group, crayfish fed BSFL14 had higher levels of glutathione peroxidase, catalase acid and alkaline phosphatase and the lowest malondialdehyde (MDA) content in hemocytes. The mRNA expression of CqBAF, HSP70 and MnSOD in the hepatopancreas of crayfish showed an increasing trend. Based on the second‐order polynomial regression analysis of WG, the optimal dietary replacement level of FM with YM meal and BSFL was determined to be 21.9% and 17.1% for juvenile C. quadricarinatus.
