Ecological Relationships between Biotic and Abiotic parameters within the establishment of Fish Farming Cage Culture in the southern Caspian Sea
Journal Title: International Journal of Farming and Allied Sciences - Year 2016, Vol 5, Issue 7
Abstract
This research examines the abundance and biomass of biota factor with the relation of some physicochemical parameters at the fish cage culture in the southern Caspian Sea (KelarabadMazandaran, Iran) in 2013 to 2015. Seasonal sampling was conducted at three stations, station1 (fish cage site), station 2(at a distance of 500 m west), and station 3 (at a 50 meters east of the fish cages). The aims of this study were to investigate the relationship between the density and biomass of phytoplankton, zooplankton and macrobenthos and the concentration of some heavy metals and petroleum parameters. A total of 38 species of phytoplankton, 6 species of zooplankton and 7 species of macrobenthos were identified. The results showed that the highest concentration of DON and DIN was recorded in winter which showed a positive correlation between phytoplankton and nutrients. At the present study, the abundance and biomass of phytoplankton showed reduced in the spring but in contrast the density and biomass of zooplankton was highest which would be due to full feeding of predators, zooplankton. Comparison of Polycyclic Aromatic Hydrocarbons (PAHs) at different seasons showed that the highest amount was detected in spring and the highest concentration of Anthracene and Fluoranthene was in autumn. The results showed that the amount of pollutants in the Caspian Sea was less than the standard limited. There was not significant differences between petroleum amounts in various seasons (P>0.05). The environmental parameters analysis showed that 5 to 20 meter depths were considered as sensitive areas and a depth of 5 and 10-20 meter divided on two groups that represent the interactions between biotic and abiotic parameters on each other's activities.
