  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Yuriy Dachev Abstract Regulating the sea spaces of the UN member states is simultaneously socio-economic, political, international law and scientific and technical issue. Factors for this are the possibilities for exploitation of the seaspaces’resources, the raw materials of the seabed, as well as the protection of the marine environment. The growing shortage of raw materials and resources worldwide is drawing the attention of countries to the seabed, which contains the largest undeveloped resources. Other factors are also important - fishing, aquaculture, maritime transport, tourism, energy sector, underwater cultural heritage, and others. These as paces of Rep. Bulgaria have been regulated since 1987 by the Maritime Areas Act, and since 2000 their legal regime has been regulated by the Maritime Areas, Inland Waterways and Ports Act of the Republic of Bulgaria. It is fully compliant with

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Dmitry Kopyev Abstract Restrictions on the Russian fish products supply to the People’s Republic of China resulted in the emergence of cargo flows to China through other countries and the redirection of flows to the central part of Russia. The possible appearance of new distribution centers in the Russian Far East will create additional fish products delivery routes to the central regions of Russia and China. The paper presents methodological approaches to the selection of routes using a modification of the network problem. Keywords: Transport leg; Shipment charges; Route choice; Fish products distribution hub Introduction The functioning of the Russian economy in the context of the COVID-19 pandemic is forcing the Russian government to change the transport development strategy in the Far East of the country. The changes will also affect the

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Yongjiang Yu Abstract Using the environment physical field, the CINRAD/SA data of Jianyang and the step velocity volume processing method, the hail processes of a classic supercell storm in the northwest part of Fujian Province in China on March 5, 2010, are analyzed. The result shows that the vertical structure of upper dry and lower wet , strong vertical wind shear, positive vorticity in middle-upper levels and mesoscale low pressure in surface provided the suitable dynamic conditions environmental for the classic supercell storm. The appearance of bounded weak echo regions (BWER), lower-level hook echo and three-body scatter spike can be served as hail features of supercell on weather radar echo images. The cyclonic convergence in low levels is important indicator in the initial and developing stages of the hailstorm system. Keywords: Supercell; SVVP; Horizontal circulation

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by:  P Padmavathi Abstract Mola alexandrine , commonly known as bump-head sunfish has been reported for the first time from Andhra Pradesh coastal waters. A detailed morphological description of the specimen is provided, and the morphometric and meristic data are compared with those of the same species reported by earlier workers. Historical records of the family Molidae from Indian waters are summarized and discussed. Keywords: First record; Mola alexandrine ; Morphometrics and meristics; Ocean sunfish Introduction The ocean sunfishes belonging to the family Molidae are composed of three genera ( Ranzania, Masturus and Mola ) with five valid species viz., Ranzania laevis (Pennant 1776), Masturus lanceolatus (Lienard 1840), Mola mola (Linnaeus 1758), Mola tecta (Nyegaard et al. 2017) and Mola alexandrini (Ranzani 1839) [1-4]. Family Molidae is monop

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Devashish Kar Introduction The water bodies under `Lentic’ category is said to form the `Standing water series’. Although the name is `standing water’ the water in such bodies is in motion in different ways. Hence, `standing water’ does not necessarily mean `static’. It simply means that water does not flow [1-3]. Until recently, many naturalists, including biologists, thought the lentic bodies (wetlands, lakes, etc.) to be much the same wherever they occur; because similarities are often found among different kinds of lentic bodies about their physico-chemical and biological features. Although a partial survival of this idea is still prevalent among many laymen; with the advent of limnology, it has been established that, lentic bodies as a class, manifest a most amazing physico-chemical and biological diversity. Further, as a partial indication of lentic bodies diversity, it could well

       Oceanography & Fisheries Open Access Journal Juniper publishers Authored by: D C Escobedo Urias Abstract The concentrations of dissolved trace metals (Fe, Mn, Cr, Cu, Co, Ni, Pb, Zn, Cd, Sr, V, As) were analyzed in 56 water samples from the intertidal zone of the Mexican Caribbean coast during 2019 and 2020. The higher concentrations of dissolved metals (especially Pb, Ni, Cd) in 2019, suggest the influence of anthropogenic inputs mainly related to an intense development of tourism in the region. In 2020, higher variability was observed in the distribution pattern of metals related to the reduction in tourism activity due to the COVID 19 pandemic and the simultaneous enrichment effect from the runoff during the rainy episodes. The generation of anoxic regions in some beaches due to the great accumulation of Sargassum influences the mechanisms of mobilization/enrichment of dissolved metals (especially Ni, Cd). The concentrations of metals showed an increase of
