Heavy Metal Levels on Largemouth Bass (Micropterus salmoides Lacépède, 1802) from Tagus River Basin- Juniper Publishers

Image
  Juniper Publishers -  Journal of Oceanography Introduction The Tagus River is the longest waterway in the Iberian Peninsula (1,007km) with source in Albarracin mountain- Spain and mouth in a wide estuary near Lisbon - Portugal. Throughout 32% of its waterway Tagus River influences the Portuguese territory with several irrigation dams and hydroelectric power plants. For decades, this river has received environmental pollutants from increased activities in industrial, domestic and agricultural systems, and also from a Spanish nuclear power plant that is 37 years old. This nuclear power plant is about to 100km far from the Portuguese border. For all those reasons it is very important to know the level of contamination of aquatic animals living in Tagus River. In many cases the toxicity caused by heavy metals is sublethal. Therefore, the animals can survive long enough to accumulate those metals and transfer them along the food chain. Historically, fish consumption per capita in Portugal

A Review of Recent Status on Stingrays (Chondrichthyes: Dasyatidae) In Indonesian Waters- Juniper Publishers

Image
  Juniper Publishers -  Journal of Oceanography Abstract In this paper, the status of stingrays (family Dasyatidae) in Indonesian waters are summarized. There are 40 valid species of stingrays recorded here. Based on distribution of stingrays within seven faunal region of Indonesia, Kalimantan of Indonesian Borneo has 29 species, the largest diversity among other islands; following Sumatra (27 sepecies), Java (25 species), Sulawesi (14 species), Lesser Sundas (16), Mollucas (9 species) and Papua (17 species). According to the recent of Red List of Threatened Species of the International Union for the Conservation of Nature's (IUCN 2017), there are 18 species are listed as threatened species (under Endangered and Vulnerable status), 2 as Near Threatened (NT), 3 as Data Deficient (DD), 5 s as Least Concern (LC) and 12 species are Not Evaluated (NE). Five species listed as Endangered should have high prioritize for conservation:  Fluvitrygon oxyrhynchus  (Sauvage, 1878);  F. kittipong

Influence of Porosity in Quantitative Analysis of Heavy Mineral Placer Deposits- Juniper Publishers

Image
  Juniper Publishers -  Journal of Oceanography Abstract The Heavy mineral analysis of the beach sediment is one of the finest ways to interpret the presence of the placer deposits in the coast. The point counting method is a widely used technique, which is employed for the quantitative analysis of heavy minerals. Nevertheless, this method is not applicable in case of large scale volumetric or spatial investigations as the surficial sediments occupy an inaccurate space due to its irregular grain size. Therefore, porosity is an important feature that has to be considered for the analyzing the quantitative distribution of the placer minerals present in the surface sediments. This paper highlights the effect of porosity in the heavy mineral distribution with respect to the grain size. The outcome from this research helps to enhance the results in quantitative analysis of heavy minerals. Keywords:  Heavy minerals, porosity, beach, sediments, grain size Go to Heavy mineral analysis Quantita

Voluntary Commitments (VCs) under the UN Oceans Conference- Are VCs Advancing the Implementation of SDG 14?- Juniper Publishers

  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

Effect of Origanum vulgare Extract on Immune Responses and Heamatological Parameters of Rainbow Trout (Oncorhynchus mykiss)- Juniper Publishers

Image
  Juniper Publishers -  Journal of Oceanography Abstract In this study,  Origanum vulgare  extract was used to evaluate its effects on immune responses and hematological parameters of rainbow trout  (Oncorhynchus mykiss).  Six hundred (600) averages mean weight 13±0.05g rainbow trout ( Oncorhynchus mykiss)  were randomly allocated into two groups including placebo-treated group (control), and  Origanum vulgare  extract-treated group, each of three replicates. The fishes were hand-fed once a day with diet medicated placebo or  Origanum vulgare  extract (OE) at a rate of 1% of feed weight in the first feeding for 8 weeks. At the end of every two weeks 24hrs after feeding, fish were bled from caudal vein and blood samples were analyzed for some of hematological and immunological parameters. The results showed that serum total protein, albumin and globulin, respiratory burst activity, phagocytic activity and serum lysozyme activity vary among the two treatment groups which were found to be
