This study was designed to investigate the effect of magnetic water technique on growth performance, feed utilization, water quality parameters and some blood parameters of sex reversed (all-male) Nile tilapia (Oreochromis niloticus) fry.
Fry were randomly distributed in three experimental groups reared in glass aquaria.
The experiment was based on two levels of stocking density [low level ٧ fry/aquarium ( ٨٠ fry /m٣) and high level ١٤ fry/aquarium (١٦٠ fry /m٣)].The same levels were treated with magnetic water at ٠.٧ Tesla compared with the control groups ordinary water (٠ Tesla) and each group was triplicated, with ٠.٣g / fry an average initial weight.
Experimental fish were fed on commercial diet (٣١.٧١% protein and ٤١٧٠.٧ Kcal GE/kg diet).
At the end of the experiment, the results indicated that growth performance and feed utilization improved significantly (P>٠.٠١) in magnetic water treatment compared to the control groups with high and low stocking densities.
The present study recorded that NH٤, NO٣, NO٢ and DO in magnetic water treatment with high and low stocking densities improved significantly (P>٠.٠١) in comparison with the control groups.
While there were no significant differences (P>٠.٠٥) in pH.
As for blood parameters, there were no significant (P<٠.٠١) differences in them between high and low stocking densities.
Results indicated that fish reared in magnetic water treatment improved significantly (P>٠.٠١) compared to those in the control groups in high and low densities.
In short, applying magnetic water on aquaculture definitely on Nile tilapia farming improves growth performance
