Abstract

Sampling of sediments from the southern region of Tiyab was carried out for fourteen patrols every two months to determine the sediment distribution of bedding, pathogenic bacteria from April to October 1996. Gravel particles at station 2 with a value of 1.5 in rank 1 and then station 3 and 2 in the order of 2 and 1.7 respectively. Silt particles at station 1 with the highest values ​​of 1.8 ± 22.6% have the highest and then stations 3 and 2, respectively, with 2.5 ± 15.7 and 3.2 ± 11.9% respectively. The total particles at Stage 3 with 21.7 ± 1.8% had the highest and stations 2 and 1 with 18.8 ± 18 and 16.3 ± 2.1% in the next. Total organic matter with 6.3 ± 0.4% at stations 2 has the highest and stations 3 and 1 with values ​​of 0.6 ± 6 and 0.6 ± 5.6% after station 2. The mean values ​​of T count in 3 stations indicate that stations 3, 2 and 1 are located at positions 1 through 3 with specified values. The mean values ​​of M T N indicate that stations 1, 2 and 3 are ranked 1 to 3 with average values ​​of 6.13, 6.24 and 6.16, respectively. The average total of form was assigned to stations 1, 2 and 3, with values ​​of 0.63, 0.62 and 0.610, respectively. It can be concluded that wastewater from shrimp breeding has increased the amount of organic matter and the total number of colonies.
