  Abstract Phylogeographic studies of Penaeid shrimps have revealed genetic divergence among populations between known biogeographic barriers in the western Indian Ocean, between the Bay of Bengal and the south-eastern Africa, and across the Sunda-Shelf and the Isthmus of Kra. The phylogeographic lineages identified should be considered as evolutionary significant units (ESUs) or conservation units and should be considered in the management of the Penaeids, both in aquaculture and fisheries in order to maintain the large diversity within the species in the Indo-Pacific region.

  Abstract Four specimens of red seabream Pagrus major (non-native species), were caught at the entrance of Amvrakikos Gulf and Echinades islands of the Ionian Sea (Western Greece). Identification was confirmed by genetics. Location and morphological characteristics as well as stomach content analysis and a brief history of farming attempts in the Mediterranean are presented.

  Abstract The Western Ghats has been well studied for freshwater crabs among the regions of the Indian subcontinent. Several studies on the Western Ghats crabs notwithstanding, their actual diversity is still incompletely known. The previous data on their diversity seems to be erroneous. The freshwater crabs of the Western Ghats are revisited to update the information on their diversity, distribution, endemism, and conservation, which include 888 locality records from 46 publications. The updated data comprises 62 crab species in 18 genera of the family Gecarcinucidae, including recognition of two new records from the Western Ghats: Oziotelphusa biloba and Oziotelphusa ravi. The Western Ghats crabs contribute nearly half the diversity of the Indian freshwater crabs and more than two-thirds the diversity of the Indian gecarcinucid crabs. Nearly two-thirds crab species of the Western Ghats have been reported during the last two decades. The Southern Western Ghats is rela

  Abstract The applicability of the photosynthesis equation to the analysis of the changes of global carbon cycle main participants (carbon dioxide, atmospheric oxygen, sedimentary organic carbon) is shown. Photosynthesis is manifested in antiphase changes in the average concentrations of CO 2 and O 2 in the atmosphere and in-phase changes in the concentration of oxygen in the atmosphere and the rate of burial of organic matter in the sediment. Due to the regulatory role of photosynthesis, the global carbon cycle spontaneously moves to a stationary state, what makes it possible to estimate the amount of buried organic matter in the earth’s crust. This parameter is the key in the study of the biosphere, its evolution, for the study of various geochemical correlations.

  Abstract Sustainability of ecological and social system in the marine needs the structure reform of stakeholders. We employ a classification of stakeholders; inside, outside and external stakeholders to explore the sustainable society in the marine. From the beginning of the 21th century innovation of ICT improves industrial revolution of digital technologies in the proceeding of globalization. In the early stage of the globalization, global corporations do not only increase inside and outside stakeholders within their market network but also accompany rising external stakeholders. It has raised many environmental and social problems into the marine society. The digital revolution can develop the efficient connection between consumers and producers by lowering the transaction cost of markets and improve conservation of marine resources economically and ecologically. Consequently, some external stakeholders are transferring to the outside stakeholders. In addition, dis

  Abstract The experiment comprised five treatments including a control without any organic carbon addition and four different carbon sources applied in biofloc system namely sugar cane molasses, fine rice bran, cassava powder and combination of rice bran and cassava at an estimated C:N ratio of 12. The nursery phases were assessed in tanks with a volume of 450 L for 30 days. The black tiger shrimp ( Penaeus monodon ) postlarvae with an average weight of 0.01 g were randomly stocked at density of 600 Ind. m-3. Results showed that carbohydrate addition resulted in better water quality and shrimp performance than that in the control system. Among the different carbon sources used, cassava and molasses have slightly increased the survival of shrimp. Overall, use of sugar cane molasses as carbon source seem to be more effective that gave better water quality, survival and production of shrimp.

  Abstract Floating marine debris represent a threat to marine and coastal ecology. Since the Mediterranean basin is one of the highly impacted regions, both by the coastal pollution as well as from sea traffic, the potential harm of a floating pollution on the marine ecology could be overwhelming in this area. Our study area covers the central Mediterranean crossing that connects the western and eastern Mediterranean and is one of the areas impacted by a high intensity of sea traffic. To identify regions in the central Mediterranean that could be more exposed by high concentration of floating marine pollutants we use Leeway model for lower windage small-size particles. We perform numerical simulation of a large ensemble of Lagrangian particles that approximate at-sea debris. The particles are forced by high-resolution sea kinematics from the Copernicus Marine Environment Monitoring Service (CMEMS) and 10 m atmospheric wind from the European Centre for Medium-Range We
