  Juniper Publishers -  Journal of Oceanography Abstract Recently luminous  Vibrio campbellii  has been recognised as a cosmopolitan pathogen in seafood and aquaculture industry. The significance of this study is to present the findings derived from longer-term starvation experiment on intense luminescence producing bacteria  Vibrio campbellii  strain STF1. This strain was isolated from surface swab of  Synanceia verrucosa  (stone fish) and subjected to the starvation-survival procedure. The viability rate of this culture was determined following spread plate method by counting viable cells in starter inoculum and in the same starvation culture. It was observed that 90 to 95% of luminous bacteria could remain viable for over 4 years under nutrient deficiency condition. This study also determines the effectiveness of the preservation of luminous bacteria in sterile sweater. Keywords:  Luminous bacteria; Vibrio campbellii; Starvation; Survival ...

  Juniper Publishers -  Journal of Oceanography Abstract Coastal communities are blessed with abundance of natural resources nevertheless, they remain poor especially in developing countries. The livelihoods of the inhabitants of coastal areas are deficient in proper economic growth. To improve sustainable ways of earning from various income sources using their existing resources, approaches to develop alternative livelihood is a common practice. Coastal communities of Bangladesh occupied on southeastern coasts, known to have a significant number of commercially valuable seaweeds grown seasonally. The communities here are aware of the value yet have no idea how to use it. The current study elucidated the response of coastal inhabitants' on potentiality of seaweed farming as an alternate income generation (AIG) activity to improve the livelihood of the coastal community in Bangladesh. Keywords: Seaweed; Alternative income generation (AIG); Bangladesh; Coasta...

  Juniper Publishers -  Journal of Oceanography Abstract Nepal has a considerable hydropower potentiality, however the analysis of Kaligandaki River Basin optimization of power potentiality and subsequently identified two critical impacts of climate change-GLOF's and variability of runoff along with temperature difference are most pronounced during the dry winter season, and least during the height of the monsoon. In Himalaya region the Intergovernmental Panel on Climate Change (IPCC) has indicated that global warming is occurring relatively faster in recent decades, with the rate of temperature increase being greater in the high altitude Himalaya, then lowland parts of Nepal [ 1 ]. It is more susceptible to impacts of climate change than a reservoir based hydro installation, on meteorological data obtained from Lete station, near a hydropower project site (Kaligandaki Gorge Hydropower), precipitation patterns slightly increase of 0.28mm, however overall steepl...

  Juniper Publishers -  Journal of Oceanography Abstract The abundance and community composition of zooplankton is spatially and temporally variable so it requires sampling over space and time. Quantitative assessment of biomass, community composition, and abundance is sensitive for sampling methodology, including the location and seasonal timing of sampling, as well as mesh size and gear type. Therefore, repeated and consistent sampling is essential to determine the changes in zooplankton distribution, abundance, community composition and seasonal timing at time scales that have impacts on higher trophic levels. In the present study, El-Mex Bay is highly diversified (204 forms) but low standing crop (annual average 8935 organisms/m 3 ). Using GIS and the other mapping applications give an easy and clear image about the distribution of aquatic fauna especially microscopic forms which help in understanding the dynamic of biological ecosystem. ...
