  Oceanography & Fisheries Open Access Journal Juniper publishers Authored by:  Kantha Deivi Arunachalama Abstract Seasonal variations in physicochemical parameters and fish diversity, population dynamics, species index, and IUSN status were investigated in this study; quantitative samples were collected monthly from January 2019 to December 2020 around the Kalpakkam coastal water in the Bay of Bengal (BOB). Water and sediment parameters are compared to fish diversity. The Zoological Survey of India confirmed the existence of 102 fish species collected along the coast, divided into two groups, 22 orders, and 56 families. Fish diversity was calculated in five villages using the species index, species richness, and Shannon-Weiner index, with Sadras kuppam having the highest and Mahabalipuram beach having the lowest. When the collected fish species were compared to the International Union for Conservation of Nature (IUCN) threatened lists, 46.08 % were determin...

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by:  Augustine Ehireme Okonofua Opinion A unique characteristic of viruses is that they are always associated with livings things (cells). This is because they are totally depended upon their hosts existence. This total host dependency makes the study of viruses extremely difficult since the internal characteristics of the host’s cell interferes with observations made. Unlike other micro-organisms like bacteria, viruses cannot be cultivated on a laboratory media because of their host’s dependency. They therefore cannot be cultivated solely in the presence of organic or inorganic nutrient medium. They can only be grown by the use of living cells and tissues. In laboratory conditions this living cells and tissues act as viral culture medium. For the purpose of viral cultivation, the relevant cells or tissue have to be cultivated under laboratory conditions. Therefore, for the growth of...

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by  Rajib Biswas Introduction With the rise in world population, the pollution in varieties form is also escalating. The rise of technology and industrial revolution has beefed up many forms of pollution into the environment. As we can see, there are plastic pollution, aquatic pollution, sound pollution, light pollution and many more. On a closer note, it is seen that these pollutions are somewhat coupled to each other either directly or indirectly. Another evolving menace in the form of microplastics is slowly invading our ecosystem [1]. This can be treated as a subset of plastic pollution. They are slowly polluting the aquatic systems; thereby jeopardizing the existing ecosystem. This short communication overviews the basics of microplastics. It further highlights the dreadful impacts on the aquatic species, followed by future recommendations. ...

  Juniper Publishers -  Journal of Oceanography Abstract Antarctica is one of the most surprising places in terms of biodiversity, and is one of the regions less affected by humans. The study of pollution in Antarctica can help us understand the real influence of human activities on the environmental pollution from polar regions. Trace elements are worrisome to biota for their effects on health and ecosystems. These chemicals enter the water through natural processes and human activities, and can affect wildlife and humans. The northern of Antarctic Peninsula and the South Shetland islands are particularly vulnerable because of their proximity to the continent and for having major human pressure. Our studies have focused on the determination of metals in penguin excreta, as they are non-invasive materials which can be suitable for the monitoring of chemicals in the environment. Go to Introduction Heavy metals (or most recently known as trace elements) are chemicals whose expos...

  Juniper Publishers -  Journal of Oceanography Abstract The aim of the present study was to investigate the effect of water source on survival rate %, growth performance, feed utilization, fish yield, economic evaluation and production of Nile tilapia ( Oreochromis niloticus)  monosex reared in earthen ponds. Nine earthen ponds were used and divided into three categories of three earthen ponds each. The average size of each pond was approximately 5200m2, 6000 monosex all male Nile tilapia were used in each pond and were stocked for 192 days. The fingerlings average weight was 4.38±0.03g/ fish, the fish were fed using a floating feed 25% crude protein, and were fed at a daily rate of 3% of their body weight. Results showed that body weight was increased significantly (P<0.05) with well water to 472.33g/fish. While were 354.17 and 320.17g/fish for fresh and agricultural drainage water, respectively. Specific growth rates (SGR%) increased with well water compared to both...
