| Abstract | ||
| The present study conducted to evaluate the effect rearing fish in floating cages on aquatic ecology of Tigris River. Four locations were choose in (Jedaydate Al-Shat) (Al-Rashdiya) north of Baghdad, (Aladhamiya) north Rusafa, Al-Jadriya south Resafa and Al-Madaayn south of Baghdad. Half month water Sampling were collected from five stations for each of the four locations; before the cages; in the cages; immediately after cages; 50m after cages and lastly 100m after cages. Results showed that nitrite level were 2.6-6.2, 1-5.7, 2.6-6.2, 2-8.9 mg/l in the four locations respectively and it was referred significantly (P≤0.01), phosphate level were 0.01-0.7, 0.08-0.3, 0.002-1, 0.06-0.5 mg/l with significant difference for the four locations respectively. All the data was in the valid range which recommended by FAO. Also in the result fish rearing in cages didn’t affect the ecological load | ||
