“…The results of the present study revealed that there was no significant difference in SOD and CAT activity between various treatments although the highest levels were reported in probiotic-supplemented groups. In accordance with the results of the current study, Kord et al (2021) reported that the best results for CAT and SOD levels were recorded in Nile tilapia supplemented with Sanolife PRO-F. In a similar sense, supplementation of diet with probiotics in biofloc systems enhanced SOD and CAT in Nile tilapia (Mohammadi et al, 2021) and SOD in red tilapia (Bañuelos-Vargas et al, 2021).…”

“…Our findings presented that fish fed diets enriched with multistrain probiotics displayed higher globulin levels than fish fed no diets enriched with the mono-strain. Similarly, a similar increase in globulin values in the Nile tilapia group fed diets enriched with Sanolife PRO-F (Kord et al, 2021) and Bacilli-based probiotics (Reda & Selim, 2015) was reported. Interestingly, there was a decrease in AST levels in fish groups fed on multi-strain probioticsenriched diets.…”

“…Probiotics include bacteria, yeast and filamentous fungi, which can be used individually or in mixtures or consortia (Ringø et al, 2020). Several studies have shown that enrichment of Nile tilapia diet with probiotics enhanced growth (Elsabagh et al, 2018;Khunrang et al, 2021;Silva et al, 2021;Tachibana et al, 2021), boosted immunity (Kord et al, 2021;Kuebutornye et al, 2020) and protected from infections (Aly et al, 2008;Cavalcante et al, 2020;Liu et al, 2021;Mohammadi et al, 2021;Ramos et al, 2017;Tan et al, 2019;Waiyamitra et al, 2020). Similarly, the use of probiotics showed positive effects in shellfish (Abdel-Tawwab et al, 2020;Butt et al, 2021;Kesselring et al, 2019;Knipe et al, 2021;Ringø, 2020;Vargas-Albores et al, 2017), rainbow trout (Al-Hisnawi et al, 2019) and common carp (Yanbo & Zirong, 2006;Zaheri-Abdehvand et al, 2018).…”

This study assessed the impact of dietary supplementation of single-and multi-strain Bacillus-based probiotics on growth performance, intestinal morphometry, blood parameters, immune-oxidative status and transcriptomic response of Nile tilapia for 60 days. Fish (N = 150, 1.632 ± 0.035 g) were allocated into five experimental groups:(1) Control group (CG) that was fed on a basal diet; (2) Eco. 0.01%, received basal diet with 0.1 g/kg Ecobiol; (3) Eco. 0.02%, received basal diet with 0.2 g/kg Ecobiol;(4) Pro-F FMC 0.001%, received basal diet with 0.001 g/kg Sanolife PRO-F FMC; (5) Pro-F FMC 0.002%, received basal diet with 0.002 g/kg Pro-F-FMC. Fish received Pro-F FMC 0.002% displayed higher growth performance than CG (p < 0.05), while Pro-F FMC 0.001% exhibited the highest intestinal weight. Sanolife PRO-F FMC supplementation improved intestinal villi length and goblet cell number while decreased inter-villi space (p < 0.05). The best haemoglobin, haematocrit and monocyte per cent were observed in Pro-F FMC 0.001%, whereas Pro-F FMC 0.002% revealed the best leukocyte, lymphocyte and neutrophil contents. Pro-F FMC-supplemented groups showed better phagocytic activity, phagocytic index and lysozyme activity than Ecobiol-supplemented groups and CG. Pro-F FMC 0.001% enrichment induced the highest upregulation level of NPYα, AgRp-2, ghrelin and GH-1, whereas Pro-F FMC 0.002% significantly upregulated IGF-1 and IGF-2 gene expression. Eco. 0.02% induced the highest upregulation level of orexin and galanin gene expression.Conclusively, dietary enrichment with single-or multi-strain Bacillus-based probiotics is likely to improve growth, immunological parameters and transcriptomic response of Nile tilapia.

“…This is mainly driven by lack of access to high quality food products. Fisheries and aquaculture programs can address and mitigate issues of malnutrition in the world by increasing the access to fish ( 12 , 13 ) due to its nutritional value. Therefore, increasing fish production could increase the access to fish products and improve the nutritional status in children which has the potential to end malnutrition and food insecurity.…”

Fish is a relatively cheap and accessible source of animal protein for human consumption even in rural communities. It is critical for global food and nutrition security, and its consumption continues to increase. As a highly nutritious food, fish consumption is highly recommended for children and expectant mothers for normal growth and development. The present paper explores the nutritional value of fish as approach to nutrition in children and its benefits. The findings reveal that fish is a valuable source of essential amino acids (EAA) and polyunsaturated fatty acids (PUFAs) that play important physiological functions for maintenance and development of fetuses, neonates, and infant brains. Therefore, it could be a valuable tool in the fight against food insecurity and malnutrition. However, fish and fish products are also highly susceptible to contamination by various organic and inorganic compounds that threaten public health. Particularly, heavy metals and biogenic amines (BAs) have shown adverse effects when contaminated fish is consumed, and the effects in children have been worse. Hence, while fish consumption is highly recommended for children's nutrition, the safety and quality of the product should always be checked to safeguard public health.

“…The Blue crab, Callinectes sapidus, is widely reported in various Mediterranean regions [6,7]. Morphometrics and length-weight relations are often used to evaluate population characteristics [8][9][10] and determine the size of sexual maturity or possible variability among species in the stock assessment of commercially significant species [11,12]. The production of crabs largely depends on the quality of the broodstock, and the male reproductive system information is crucial when collecting the matured males for breeding [13].…”

The blue crab, Callinectes sapidus Rathbun, 1896, is considered to be a luxury meal, especially in touristic cities. It contains more than 20 types of amino acids and provides all the needed amounts for human growth. This study describes the morphology and complex differentiation in the gonadosomatic index, morphological and ultrastructure features of the reproductive system, spermatogenesis, and spermatophores structure; this is due to the need to maintain natural and fishing stocks. Mature adult male crabs (carapace length 59 ± 7.12; width 126 ± 18.8 mm) were obtained from Abu-Qir Bay from November 2018 to October 2019 and transported alive in seawater to the laboratory. The reproductive system was dissected and weighed to the nearest 0.001g using the electronic balance, and the gonadosomatic index was subsequently calculated. The morphological analysis showed the developing testes with highly compacted seminiferous tubules. Using Periodic acid–Schiff stain, the spermatophore appeared with a zigzag-shaped wall that indicates its carbohydrate constituents. Each Spermatophore consisted of an inner spermatozoal mass embedded in a matrix, whose main components were secretions 1 and 2, and an outer thin acellular layer composed of secretions 3 and 4 from the anterior vas deferens (AVD). Secretions 5 and 6 (S5 and S6) also appeared with carbohydrate constituents using Mallory triple stain. The transverse section of the middle vas deferens (MVD) showed spermatophores with rod-shaped secretion S6 and granular secretions 7 (S7), forming a complex matrix between spermatophores. The secretion found in the MVD was granular, strongly acidophilic, and secreted by its highly columnar epithelium (S7). The ultrastructure showed that the testes were surrounded by a monolayer of myoid cells with an elongated nucleus, which also contained the following stages: spermatogonia, primary spermatocyte, secondary spermatocytes, and spermatids as well as spermatozoa. On the other hand, scanning electron microscope studies for fully formed spermatophore taken from the middle part of the vas deferens indicated that it is ellipsoidal in its outline with terminal stalk. Furthermore, the spermatophore was surrounded by a thick capsule of non-cellular substances and contained mature spermatozoa.
