Review of World Aquaculture and Oceanography

Authored by Sunil kumar P

The main objective of this issue is to publish most complete and reliable source of information on research and current developments in the areas of aquaculture and oceanography. This issue covers areas in marine, brackish water and environmental aspects of fisheries. It provides an international forum for publication of papers in areas of fisheries science and aquaculture. Aquaculture contributed 43 per cent of aquatic animal food for human consumption in 2007 and is expected to grow further to meet the future demand. It is very diverse and, contrary to many perceptions, dominated by shellfish and herbivorous and omnivorous pond fishes. The rapid growth in the production of carnivorous species such as salmon, shrimp and catfish has been driven by globalizing trade and favourable economics of larger scale intensive farming.
Aquaculture includes species at any tropic level that are grown for domestic consumption or export. Aquaculture has some positive impacts on biodiversity. Cultured seafood can reduce pressure on overexploited wild stocks, stocked organisms may enhance depleted stocks, aquaculture often boosts natural production and species diversity, and employment in aquaculture may replace more destructive resource uses. On the negative side, species that escape from aquaculture can become invasive in areas where they are nonnative, effluents from aquaculture can cause eutrophication, ecologically sensitive land may be converted for aquaculture use, aquaculture species may consume increasingly scarce fish meal, and aquaculture species may transmit diseases to wild fish. Most likely, aquaculture will continue to grow at significant rates through 2025, and will remain the most rapidly increasing food production system. In the area of aquaculture increased output is likely to require expansion in new environments, further intensification and efficiency gains for more sustainable and cost-effective production. The trend towards enhanced intensive systems with key monocultures remains strong and, at least for the foreseeable future, will be a significant contributor to future supplies. Dependence on external feeds, water and energy are key issues. Some new species will enter production and policies that support the reduction of resource footprints and improve integration could lead to new developments as well as reversing decline in some more traditional systems.

Bioluminescence in Fishes: Diversity and Functions- Juniper Publishers

                  Juniper Publishers -  Journal of Oceanography Introduction Bioluminescence is a amazing biological phenomen, which can be found in terrestrial and oceanic environments. Numerous bioluminescent taxa were described from the marine environment [ 1 - 2 ]. Bioluminescence is especially abundant in the deep-sea. The majority of luminescent taxa are invertebrate animals. In contrast to the high diversity in invertebrates, vertebrates lack bioluminescent light organs, with the exception of an amazing diversity in teleosts and some shark species. A recent paper reported that bioluminescence appeared in ray finned fishes in 27 independent evolutionary events [ 3 ]. Bioluminescent light is generated in spezialized light organs based on a oxyidation of a light emitting luciferine in the presence of oxygene and the enzyme luciferin [ 1 , 4 ]. Most of the bioluminescent species produce blue green light in the wavelength range around Xmax ~475nm [ 1 ]. Luminescence in fishes c

SDS-PAGE Electrophoresis of Ocypode rotundata Miers, 1882 and O. ceratophthalma Pallas, 1772 using Muscle Tissue along the Coast of Pakistan

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by Sahir Odhano Abstract Electrophoretic studies for the identification of ghost crabs (Ocypode rotundata and Ocypode ceratophthalma) using the SDS-PAGE were performed on protein patterns along the Sandspit coastal areas. The muscle tissues were used to estimate the molecular mass of proteins through SDS-PAGE electrophoresis. Electrophoretic settings were standardized to use 10% acrylamide resolving gel and 5% acrylamide stacking gel. A discontinuous buffer system was used following the protocols of Laemmli (1970) to observe the relative mobility and molecular weight of proteins. In O. rotundata total of 6 protein bands were resolved among them band-5 was found similar in size to the marker used (BSA = 66 kDa MW). Whereas in O. ceratophthalma total of 8 protein bands were resolved among them three protein bands (band-6, band-7, and band-8) were found to be higher in size than the molecular mar

Environmental Perception of Recreational Fishers in Urban Beaches

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by:  Jacqueline S Silva-Cavalcanti Abstract Recreational fishers depend on the good quality of those environments. The assessment of the environmental perception of social actors who show a sense of belonging to the landscape can better describe the impacts on the environment. This study aimed to assess the recreational fishers’ perception of the environmental quality in four urban beaches. 170 recreational fishers agreed to participate in the research. They were required to respond to questions about their fishing strategies and their perception of the environmental quality of the beaches and the possible impacts on the fishing activity. Based on the responses presented, a description of both local fishing activities made, as well as an analysis of the perception of the beaches’ environmental quality for fishers. On average, the recreational fisher ones have been working for 16.2 years. Pollu
