| Bahrakan is one of the four areas of major Persian Gulf oil reservoir and is of economic importance.
Sediment particle size is an important factor in distribution of the benthic fauna. In the ecological study of
this region’s Ostracods, 14 stations were determined in two transects parallel to the coast. Sampling was
done by grab and corer 8.5 cm2 of 5 cm of surface sediments. Sediments with a 63 mm sieve were washed
and stained with Rose Bengal. These organisms were isolated by flotation with the CCL4. The maximum
density at 1 m depth in winter was 10495 in d/10 cm2 and lowest density in the summer was 3444 ind/10
cm2. In 1 min depth, diversity Brillou in index, Hill index and Simpson index were 2.03, 0.78 and 0.44,
respectively. Fitness was calculated using MDS in total stations and in both seasons. The stress value was
0.01. |
