Comment on Linking the Sex Difference in PCB Concentrations of Fish to Release of Eggs at Spawning: Time to Jettison the Dogma- Juniper Publishers

  Juniper Publishers -  Journal of Oceanography Opinion For the past 20 years or so, a commonly used explanation in the scientific literature for higher polychlorinated biphenyl (PCB) concentrations in male fish than in female fish has been that females lose a high proportion of their PCB body burden by releasing eggs at spawning time, and therefore the females undergo a substantial decrease in their PCB concentration immediately after spawning due to shedding of their eggs [ 1 ]. Indeed, this explanation can be viewed as the conventional wisdom used by toxicologists to account for differences in PCB concentrations between the sexes of fish. On the surface, this explanation seems plausible. PCBs are lipid soluble, and eggs are thought to be relatively high in lipid concentration. If a sufficiently high proportion of the PCB body burden within a female fish is transferred to the eggs, then the release of eggs at spawning would be expected to result in a dramatic decrease in the PCB conc

Linking Ocean Observation and Fisheries - Relevance to Deep Ocean Living Resources- Juniper Publishers

  Juniper Publishers -  Journal of Oceanography Abstract Systematic ocean observation for real time data collection during the last three decades, development of sensors and tools, and ocean modelling have paved the way for better understanding of the ocean processes and better prediction of coastal hazards like cyclones, tsunami, storm surge, etc., leading to direct societal benefits globally. In particular global ARGO float data have brought in remarkable changes in ocean science studies. This paper discusses about the growing need to link ocean observation to fisheries and futuristic approach about deep ocean marine living resources Go to Introduction The goal of fisheries oceanography is to understand the oceanographic and ecological processes that affect fishery abundance, distribution, and availability and then apply this understanding to improve fisheries assessment and management. Ecophysiology is the interrelationship between the environment and an organism's physiology [

Spatial Variation of Demersal Fish Communities in the Platform and Channel of Yucatan- Juniper Publishers

  Juniper Publishers -  Journal of Oceanography Abstract The nature semi-closed of the Gulf of Mexico, together with its oceanographic pattern and freshwater discharges, provide a rich region considering biodiversity. However, the demersal fish community structure is almost not known, even that this great ecosystem has been continuously impacted by oils spills and over exploitations of fishery resources. The present study was developed to evaluate spatial variation of the demersal fish community and with depth gradientin area of the Platform and Channel of Yucatan, southern Gulf of Mexico. Sampling was realized in 18 stations with an oceanographic ship using a shrimp trawl at 99m as average depth. A total of 129 species were recorded, where Serranidae family was the most diverse (10 species), following in importance Paralichthyidae (eight species), Sparidae and Triglidae with seven species each. The most representative specie considering density was  Syacium papillosum  (12.4% from tot

Scientific Productivity of Oceanography Literature: A Scientometric Analysis- Juniper Publishers

Image
  Juniper Publishers -  Journal of Oceanography Abstract The study examines India’s performance based on its publication output in Oceanography literature during 2011–2015, based on various aspect of the oceanography research such as growth of papers (year wise), most prolific authors, document types, institutions involved, Sources wise distribution, subject wise distribution of publications and international collaboration linkages. The study reveals that, most of the researchers preferred to publish their research results in journals; as such 1.92% of articles were published in journals, more numbers of articles were published in the year 2015, the study shows that overall average citation per paper was 2.32, all the studies will be helpful for its further development. Further this study also identified to analyses coverage growth rates, coverage growth rates, source wise. Degree of collaboration, institutions wise and Geographical wise distribution of the literature. Keywords:  Scien
