Abstract: (7939 Views) |
| The aim of this study was to investigate benthic invertebrate community and application of AMBI
(AZTI's Marine Biotic Index) for determining quality of health status in Bahmanshir River in vicinity of
Abadan City. Sampling was done to collect macrobenthose from six stations seasonally through March
2011 to Septambre 2011. Totally, 67 species identified in the study area. Portions of identified species
were as follow 40 polychates, 4 gastropods, 11 amphipods, 9 bivalves, 1 britle star and 1 cumacean and 1
tanaid. The macrobenthose abundances ranged between 26.37 ind.m-2 to 66.58 ind.m-2 in summer and
winter respectively. The ANOVA showed signifant difference in seasonal abundances (P<0.05). The
maximum absolute mean of abundances found in station3 (162.3 ind.m-2) and the least was related to
station 6 (4.8 ind.m-2). The results of ANOVA showed signifant difference of abundances between stations
(P<0.05). The health of stations were examined by AMBI and determined that station 6 and station 3 had
bad and good status respectively. |
