Assessment the effect of exposure to microplastics in Nile Tilapia (Oreochromis niloticus) early juvenile: I. blood biomarkers.

Chemosphere, 2019
There is a scarcity of knowledge about the impacts of microplastics (MPs) on the early juvenile stage of freshwater fish. The current study aims to inspect the exposure and post-exposure recovery of microplastics (MPs) on accumulation and blood ...

Metabolic response of Nile tilapia (Oreochromis niloticus) to acute and chronic hypoxia stress

Aquaculture, 2018
Hypoxia is a critical issue in aquaculture especially in intensive aquaculture systems. Acute hypoxia stress with dissolved oxygen (DO) 0.7 ± 0.1 mg/L for 6 h and chronic hypoxia stress with DO 1.1 ± 0.1 mg/L for 4 weeks were used to investigate the ...
