  Juniper Publishers -  Journal of Oceanography Abstract The study examines the ecological and economic implications of dredging activities on fishing sites in the Niger Delta area of Nigeria. Data from secondary sources were empirically analysed and results show that dredging operations have significant effect on fishing sites. These are revealed by the magnitude of ecological and economic implications to the region, which is reflected by the level of economic value of damage caused by dredging in the area, the number of fishing sites and farm lands affected by the dredging operations. The study concludes that even though dredging is imperative for the economic survival of the area, there is need for routine studies to be conducted prior to the operations so as to ensure that dredging activities are executed in the most environmentally friendly manner in accordance to international best practices in order to mitigate ecological imbalance in the basin.

  Juniper Publishers -  Journal of Oceanography Abstract The samples were collected once in three months during 2015 from intertidal zone of Shatt al-Arab River from eight sampling sites. For the purpose of evaluating the spatial and seasonal variations in the diversity, density and abundance of invertebrates in relation to diversity of Aquatic plant and related the dynamics of water temperature, salinity, water transparency, pH, dissolved oxygen, phosphate and nitrate. The diversity and distribution patterns of certain invertebrate's species were clearly related to plants and water quality as evident from the present study. In the present study tried to assess indices invertebrate species as Shannon-Weaver index, Simpson's index, and Index of Evenness species in eight sites at Shore of Shatt Al- Arab River and predict the state of water according to species and physicochemical parameters. The indices were evaluated at individual species level and varied species to species. In...

  Juniper Publishers -  Journal of Oceanography Abstract The Adriatic Sea represents a vulnerable ecosystem and need an Integrated Coastal Management to protect, conserve and manage the coastal and marine areas. This preliminary work proposes a local case study aimed to the characterization of coastal marine habitats along Teatina coast (Abruzzo, central Italy), carrying out 11 transects parallel to the coastline. Moreover, the presence of sea turtles and cetaceans has been estimated by the analysis of specimens stranded and included in the GeoCETUS database of Centro Studi Cetacei onlus. The results show that the study area has a considerable marine biodiversity and a sustainable management is urgent for preserving the habitats and associated species. As first step the Nature 2000 network should be implemented by including the marine areas in front of each terrestrial SCIs and Natural Reserves, to create some marine protected areas along Teatina coast with the...
