Potential Influence of Shading in Freshwater Ponds on the Water Quality Parameters and the Hematological and Biochemical Profiles of Nile tilapia (Oreochromis niloticus Linnaeus, 1758)

Nile tilapia is a high-demand commodity in most developing countries including the Philippines, but its production hampered by fluctuating water temperature (WT) and dissolved oxygen (DO) concentrations, which are mostly influenced warming. Net shading has been demonstrated to reduce pond increase rate of spawning cultured tilapia. The current study aimed investigate potential effects on quality parameters, blood indices, serum biochemical profiles Fish were collected from unshaded (control) shaded (experimental) ponds three breeding cycles. WT DO concentrations measured, while hematological analyses performed. results showed that average was considerably decreased with no significant difference concentrations. Red cells, hemoglobin, lymphocyte counts significantly lower fish raised ponds, although mean corpuscular volume neutrophil higher. Likewise, Chole, TP, Alb values affected interaction cycle setup. Cortisol, Glb, K+, Cl−, Mg2+, TCa differences only cycle. Similarly, AST ALT both Water parameters (WT DO), variables correlated positively each other. In brief, prior data imply net can aquaculture stress tilapia, lessen consequences warming species production.
