“…Alkhazan et al [28] also showed a significant increase in pH as the magnetic intensity increased. Ahmed et al [12] recorded that DO and pH values in magnetic water increased as compared to control water, but ammonia was inversely decreased. Similar results were recorded in previous studies [5,29,30] pointed that the Mansoura Vet Med J 22:3 (2021) 97-104 increase in magnetic intensity led to an increase in dissolved oxygen concentration compared to normal water.…”

“…[7] reported the enhancing effect of exposure to MF on growth, immune and digestive enzyme levels in juvenile Sea cucumbers Apostichopus japonicus. Furthermore, [8]; [9]; [10] ; [11] and [12] have evaluated the effect of MF treated water on improving water quality, growth parameters, feed utilization and immunity. However, the field application of the magnetic treatment in tilapia reared under different feeding rates still new approaches and need further research.…”

The present study was designed to investigate the effect of magnetic water treatment technique and different feeding rates on growth performance, feed utilization, water quality parameters, chemical composition and intestinal histomorphometric parameters of monosex Nile tilapia (Oreochromis niloticus). Design: Experimental study with a factorial design. Fish: A total of 2880 apparently healthy monosex Nile tilapia (O. niloticus) with an average initial body weight of 69.86 ± 0.8 g were randomly distributed into 18 concreate ponds. Procedures: Experimental fish were fed on commercial diet (30.1% protein and 4600 Kcal GE/kg diet) based on three levels of feeding rate 3, 4 and 5% from fish biomass for both treated and control groups. Water was treated with magnetic waves at 0.2 Tesla (Tesla= 2000 Gauss) compared to the control group water (zero Tesla). Growth performance parameters, feed utilization, chemical composition and intestinal morphometric analysis were calculated in all groups at the end of the experiment after eight weeks. Results: The results indicated that growth performance, feed utilization and intestinal histomorphometric analyses improved significantly (P<0.01) in magnetic water groups compared to control groups at the three levels of feeding rate. In addition, water physicochemical parameters including Ammonia (NH4), Nitrate (NO3), Nitrite (NO2), PH and dissolved oxygen (DO) significantly improved in magnetic water treated groups at the three feeding rate levels. Conclusions and clinical relevance:In conclusion, magnetic treatment of water could improve water quality parameters, fish growth performance, feed utilization, and intestinal histomorphometric analyses at different feeding rate.

“…Dissolved oxygen (DO) is the most important factor in fish farming that is required for fish growth and production (Abdel-Tawwab et al, 2019). Also, hydrogen ion concentration (pH) is the master control parameter and affects the metabolism and other physiological processes in the aquatic environment (Ahmed and Abd El-Hamed, 2020). Water magnetization by magnetic device 18000 gauss (1.8 Tesla) in this study improved the water quality parameters of Nile tilapia aquarium.…”

This study aims to examine the effects of magnetic water on behaviour, performance and some physiological parameters of Nile tilapia fish and the physicochemical properties of water. Forty-eight Nile Tilapia fish with 30.95±1.75g in weight were reared under normoxia conditions and classified into two groups (n=12/aquarium, 2 replicates). Group 1: fish raised in non-magnetized water (control). Group 2: fish raised in magnetic water using a magnetic field, 18000 Gauss (MW). Fish performance, behavioural and physiological responses were examined as well as water quality parameters of the fish aquarium were measured. At the end of the experiment, fish (n=6/aquarium, 2 replicates) of two groups were exposed to 8 hours of hypoxia. Fish behaviour was recorded and water quality parameters of the fish aquarium were measured. Results revealed that the body weight and body weight gain of fish were significantly (p<0.05) increased, however, feed conversion ratio was decreased for fish reared under the use of water magnetization. Magnetic water fish showed high comfort behavioural activities with low surfacing and eliminative behaviours. Water magnetization improved significantly the dissolved oxygen, ammonia, and turbidity of the fish aquarium. Magnetic water fish showed high total protein and globulin with a lower plasma glutathione reductase (GSH). Fish of magnetic water showed a significant increase in resting and a decrease in surfacing, chasing, and biting with lower plasma cortisol when exposed to hypoxia condition. The dissolved oxygen of magnetic water was significantly more than the dissolved oxygen of normal water after hypoxia exposure. These findings suggest that using magnetic water has significant performance and behaviour benefits, as well as reduced hypoxia stress effects in Nile tilapia fish.

A 45-day study investigated the effect of magnetized water on improving the larval aquaculture of the European sea bass in the deteriorated conditions. The present study addressed the impact of magnetized water on growth performance, body proximate composition, oxidative stress indicators, water properties, and microbiota at the early larval stages. The larvae were stocked into fiberglass tanks. Four magnetic devices with different intensities in Tesla [T1 (0.015 T), T2 (0.035 T) and T3 (0. 050 T)] were manually prepared and applied in triplicates in addition to a control tank (no magnet). The results proved the suitability of using the strength of 0.035T for attaining better survival, and growth performance parameters that were significantly (P>0.01) surging the other investigated factors compared to the control. Meanwhile, this magnet dose (0.035 T) showed significantly higher crude protein content (CP%) as well as higher antioxidative activity in superoxide dismutase and catalases levels. Otherwise, microbial analysis of the different magnetized waters and the larval body showed varied counts. Thus, it was concluded that the exposure and intensity of 0.035T gave different bio-responses on the level of improving larval aquaculture and have varied physico-chemical-response withrespect to water quality.
