“…Tilapias have become the most important farmed fresh water fish after carps worldwide (Fitzsimmons & Watanabe, 2010). Farming of Nile tilapia ( Oreochromis niloticus ) is widely expanding in India because of its fast growth rate and good meat quality (Nakkina, 2016). It has a white colored meat with rich flavor, low fat, and absence of intermuscular bones.…”

Gravads were prepared from Nile tilapia (Oreochromis niloticus) and evaluated its shelf life during chilled (6°C) and iced (0°C) storage. For standardizing the gravading process, different salt:sugar combinations of gravad mix and two steaks to gravad mixture ratio (1:0.1 and 1:0.2) were selected. Gravads prepared using 1:2 salt‐sugar in the gravad mix and a ratio of 1:0.1 steaks to gravad mix was found optimum combination. Gravads prepared using the standardized combination of salt and sugar were stored at 0°C and 6°C and evaluated for its biochemical and sensorial changes. Total volatile base nitrogen (TVB‐N) increased from 10.25 mg/100 g to 29.85 and 30.66 mg/100 g on Day 41 and Day 49 for chilled and iced samples, respectively. The extend of secondary oxidation was low in both samples, registering an increase from 0.14 mg MDA/kg sample to 0.814 and 0.851 MDA/kg sample on 41st and 49th day, respectively, for chilled and iced samples. Water soluble and salt soluble nitrogen contents were reduced to 1.82 and 5.47 mg/100 g and 1.58 and 4.72 mg/100 g by the end of 41st and 49th day, respectively, for chilled and ice stored gravads. The shelf life of gravads was determined as 41 days under chilled storage and 45 days under iced storage. Practical applications Nile tilapia is widely cultured fish species in India after the Indian major carps. It is of great interest to the farmers and demand among the consumers because of its fast growth rate and good meat quality. Value addition is an effective approach to utilize this resource cost‐effectively during excessive production periods. Conversion of Nile tilapia into gravads not only increases the value but also enhances the quality and shelf life of the product. The results of the present study provide an idea of appropriate process parameters for making gravads from Nile tilapia and information on its shelf life under refrigerated storage.

“…Nile tilapia (Oreochromis niloticus) is considered the world's second-largest farmed fish species and for several reasons is rapid growth, high survival rate (Nakkina, 2016). In the aquaculture sector the use of probiotics is gaining more attention as an eco-friendly agent and safe products as antibiotics and disease-protective (Hoseinifar et al 2018).…”

The current study investigates the isolation identification of bioactive strain from fish collected from El-Burrllus region in Egypt. The objective of the current study is to identify and assess the biological profile of a new record strain in Egypt Bacillus maritimus. The molecular identification of the selected promising isolate and phylogenetic analysis confirmed the accurate identity of the isolate as Bacillus maritimus. The novelty of the present study was not due to only to the fact that the Bacillus maritimus isolate was the first record from brackish-water Egyptian fish gut, but also due to the fact that there is no previous study on the bioactivity of Bacillus maritimus and their efficiency as biogenic nanoparticles synthesis. The bioactivities for the Bacillus maritimus were investigated through different biochemical assays as antioxidant, anti-inflammatory and antimicrobial activity against six of the tested human pathogens namely; Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 8739, Enterococcus faecalis ATCC 29212, Pseudomonas aeruginosa ATCC 15442, Klebsiella pneumoniae ATCC 13883 and Streptococcus pyogenes ATCC 19615. Bacillus maritimus bacteria were grown in nutrient broth for 24 h at 37°C and the optical density was determined at 600 nm using the UV-visible spectrophotometer. The optical density (OD) of the broth was adjusted to 0.5 with sterile phosphate-buffered saline, pH 7.4 (PBS). the bacterial isolate showed antioxidant, and anti-inflammatory activities. In addition the bacteria showed great reducing agent ability as a biogenic agent for the silver nanoparticles. The phytochemical screening of the Bacillus maritimus isolates have showed varieties of bioactive groups in addition to total phenolic compounds, flavonoids, tannic acid, carbohydrates, sulfated polysaccharides, total proteins and lipids. This study highlighted also that the Bacillus maritimus isolate could also produce novel secondary metabolites. The current study report for the first time the Bacillus maritimus in Egypt. Further studies are needed to isolate and characterize more bioactive strains from Egyptian Fishes that could possibly act as novel bioactive compounds source of medical and agricultures importance.

“…The present findings regarding the physicochemical parameters measured in this study such as temperature, dissolved oxygen (DO), pH and total dissolved solids (TDS) agree with the findings of Okomoda et al (2016), Dixit et al (2015) and Rehman et al (2006) who also recorded all these physicochemical attributes of pond water containing different types of fish species. However, dissimilar findings have been reported by Nakkina et al (2016) and Hura et al (2018), which could have been due to selection of different water quality and limnological parameters.…”

Fish polyculture has resulted in high fish production per unit area, mainly due to the best utilization of all kinds of nutrients. In this nine month’s experimental study, five different fish species were stocked in five earthen ponds designated as control (one pond), treatment-T1 (two ponds) and treatment-T2 (two ponds). Fish stocked in T1 and T2 ponds were fed with a commercial feed containing 20% and 25% crude protein, respectively, whereas fish stocked in the control pond was fed with a conventional mixture of feed ingredients (fish meal, gluten, sunflower, and rice polish) having 20% CP. The fish was fed @ 3% of the fish wet body weight twice a day. The fish was sampled every fortnight. Physicochemical parameters of the ponds were measured daily. The results showed that the maximum weight gain (255 g) was recorded in Pangasius pangasius in treatment T2 and minimum (52.5 g) in Cirrhinus mrigala in the control pond. Overall, maximum fish production was recorded after harvest in treatment T2 followed by that in treatment T1 and control ponds, respectively. Overall, the commercial fish feed enriched with crude protein was very effective in promoting growth and development of pond fish.
