  Juniper Publishers -  Journal of Oceanography Abstract The edible green seaweed  Ulva fasciata  which is abundant in Tanzania, is highly nutritious and can therefore help in curbing severe malnutrition currently reported in the country. Seaweeds on the other hand, are reported to be affected by temperature. This study was therefore aimed at investigating the effect of rising temperature on the nutritive value of  Ulva fasciata.  Samples were collected at the Oysterbay shoreline in Dar es Salaam and grown under controlled conditions at the University of Dar es Salaam. Growth rate and selected nutrients (proteins, vitamin A, carbohydrates, iron, phosphorus, calcium and potassium) were determined using standard analytical methods. Data analysis was done using Paleontological statistics (PAST) version 1.27, 1999-2012 package. The results show that temperature elevation caused a decline in growth rate of  Ulva fasciata.  Furthermore, its protein cont...

Juniper Publishers- Open access journal of Oceanography and Fisheries Ecological assessment of two sandy beaches along the Kerala coast, south west coast of India: perspective to pollution The distinct nature of the two shores (Fort Cochin and Dharmadam) of south west coast of India has the potential to evaluate the ecological function and processes. This study observed two different sandy beaches; Fort Cochin and Dharmadam and examined the faunal community structure and anthropological influences. From the entire study, it was uncovered that the shorelines chosen showed disparity in their shoreline profiles and faunal composition. Anthropological invasions and natural processes lead Fort Cochin beach to the threat of obliteration. The Dharmadam beach retained a pristine appearance; however, the temporal evaluation of beach fauna and biotic indices confirmed the occurrence of disturbed community. Impacts of anthropological activities were disclosed in the study and for which...

Juniper Publishers- Open access journal of Oceanography and Fisheries Deposition of the Mn in the Tissues of Crucian Carp in the Coal Gangue Polluted Water and Natural Water Coal gangue is the solid waste material in the process of coal mining and coal washing, which contains a lot of heavy metal: Manganese (Mn), which poses a serious threat to food security and human health. In order to study the present pollution situation of Mn and the deposition of Mn in the tissues of fish from gangue polluted water of Yongcheng, Shangqiu, Mn was determined by using the flame atomic absorption method. The results show that the concentration of Mn in the heart, hepatopancreas, gills, muscles of crucian carp from pollution-free waters in Tianmu Lake were 138.96.±35.85 (μg/g ), 10.20±4.92 (μg/g), 30.02±7.62 (μg/g), 14.64±4.06(μg/g); whereas they were 316.48±23.41 (μg/g ), 25.84±6.03 (μg/g), 70.18±14.67 (μg/g), 30.09±10.44(μg/g) in the crucian carp from the coal mining subsidence area.
