  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Siyanbola A Omitoyin Abstract Fish stocks have been reported to have been depleted as a result of climate change impacts in Ilaje Local Government Area of Ondo State, Nigeria, where a large number of people depend on water bodies for their livelihood, this research therefore look into livelihood vulnerability of fisherfolks in the area to climate change and how they are coping and adapting to the changes brought by it. A Multi-stage sampling technique was employed to select a total of two hundred (200) fisherfolks within the regions, data collected were aggregated using a composite index and differential vulnerabilities LVI–IPCC was scaled from -1(least vulnerable) to 1 (most vulnerable). The result show that coastal fishing communities in Ilaje, had a higher livelihood vulnerability index (0.357) than the freshwater fishing communities (0.356), indicating relatively greater vulnerabil...

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Albert O Amosu Abstract This study was conducted to evaluate the nutrient utilization, protein requirement and proximate analysis of Wesafu from fry to fingerlings in an earthen pond. The experimental fish were monitored for comparative analysis and growth performance using commercial feed (Coppens ® 0.2mm) and wheat flour in formulating feed with 30%, 35%, 40% and 45% crude protein levels. Fry were fed thrice daily at 8am, 12 pm and 4pm with 5% body weight for 8 weeks. Samples of experimental diet and fingerlings were analyzed for proximate composition while growth performance and nutrient utilization of diet were evaluated using growth indices such as Weight Gain (WG), Percentage Weight Gain (%WG), Specific Growth Rate (SGR), Food Conversion Ratio (FCR), Gross Feed Conversion Efficiency (GFCE), Protein Intake (PI), Protein Efficiency Ratio (PER). The results revealed that the ...

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by  Devashish Kar Abstract The North-Eastern (NE) region of India includes the province of Assam, which provides enough potential for high fish production which can supplement food requirement of the region and could provide answer to the diminishing protein supply. Assam is gifted with innumerable nature’s wealth in the form different kinds of lentic and lotic water bodies. A `Haor’ is a kind of seasonal floodplain wetland which contains water for some time of the year only, particularly, during the rainy season. Definitions of other kinds of wetlands along with details about `Haors’ in the region, have been discussed in the present communication. Keywords: Wetland; Haor; Assam Hotspot; India; Asia Introduction The North-Eastern (NE) region of India, which includes the province of Assam, is typically a difficult topography with undula...

  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. ...
