The researcher has been led to carry out research on sea piracy and armed robbery in the Gulf of Guinea and its effect on shipping cost and Nigeria’s economic growth. This research was set out to realize some specific objectives, while research hypotheses were formulated in this regard to address the objectives of this study. Design/methodology/Approach: The research adopted ex-post facto design. Data were sourced through secondary means from Nigeria Maritime Administration and Safety Ag

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Arlene L Avillanosa Abstract Zooplankton samples were taken in six sampling stations at Malampaya Inner Sound, Taytay, Palawan, to determine its abundance, distribution, and diversity, and composition related to the complete lunar cycle during the month of April 2007. Horizontal towing and vertical hauling of 333 μm plankton net was conducted from the afternoon to midnight, two hours before the onset of the moon phase. 27 zooplankton taxa belonged to eight (8) different phyla identified. During the entire lunar phase, arthropods, chordates, cnidarians, and chaetognaths were present. Zooplankton appears in great abundance during nighttime, full moon, and high tide based on 1-month sampling. Higher zooplankton diversity was observed during the new and full moon, largely represented by arthropods, particularly copepods and decapods. Generally, the area has a high number of individuals but low

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Md Morshedul Alam Abstract Dipeptidy peptidase 4 (DPP4) is an enzyme that plays important role in metabolism and due to its exacerbating role in glucose metabolism, it is essential to inhibit its function to ameliorate Type 2 Diabetes Mellitus (T2DM). Vildagliptin, sitagliptin and some other drugs are being used worldwide. As a new source, marine derived bioactive peptide having DPP4 inhibitory effect would have a promising role to control its regulatory effect on disease manifestation. Keywords: DPP4 inhibition; Marine derived origin; Marine bioactive peptide Abbreviations: DPP4: Dipeptidy Peptidase 4; T2DM: Type 2 Diabetes Mellitus; GIP: Glucose-Dependent Insulinotropic Polypeptide; GLP1: Glucagon-like Peptide-1; ROS: Reactive Oxygen Species, RAGE: Receptor for Advanced Glycation End Products; FDA: Food and Drug Administration; APCs: Antigen-Presenting Cells

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Yuriy Dachev Abstract Once oil has been spilled, urgent decisions need to be made about the options available for response and clean-up in order that the environmental and socio- economic impacts are kept to the minimum. Getting the correct balance is always a difficult process and conflicts inevitably arise which need to be resolved in the best practicable manner. The advantages and disadvantages of different response options need to be considered and compared, both with each other and with the advantages and disadvantages of natural recovery. This assessment process is sometimes known as Net Environmental Benefit Analysis (NEBA).
