  Juniper Publishers -  Journal of Oceanography Abstract Most recently signed economic, political, and social agreements such as the Paris Agreement, the 2030 Agenda for Sustainable Development, or the FAO’s Blue Growth Initiative have as common objective the strengthening of the global response to the threat of climate change holding the increase in the global average temperature well below 2 °C above pre-industrial levels. Aside of the implementation of ambitious plans on adaptation and mitigation, our ability to contain climate change within safe limits depends largely on the evolution of the ocean circulation and state. The increased awareness of the rapid degradation of the ocean and its importance to the future of humanity is the result of decades of ocean research that has finally been embodied by the proclamation of a Decade of Ocean Science for Sustainable Development (2021–2030) by the United Nations General Assembly. In the framework of this program, there is an ext...

  Juniper Publishers -  Journal of Oceanography Introduction The high-level United Nations Conference to Support the Implementation of Sustainable Development Goal 14: Conserve and sustainable use the oceans, seas and marine resources for sustainable development took place in New York in June 2017. While promising to be solutions-focused with engagement from all, it aimed at slowing down the decline in the health of the oceans, for the people, the planet and prosperity; and its outcome document "Our Ocean, Our Future: Call for Action" and the approximate 1,400 registered voluntary commitments (VCs) have been praised by the UN as a "global breakthrough on the path for the health of our oceans and seas" While SDG 14 focuses on actions where there seems to be a lack of willingness, capability and cooperation from governments to reach agreements [ 1 ], VCs are a tool often used alongside official agreements and declarations in sustainable development efforts since the 2...

  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...

  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 ...
