  Juniper Publishers -  Journal of Oceanography Abstract Key to realizing the vision of marine agronomy and seaweed utilization is an understanding about all steps necessary to collect and prepare the seaweed for processing (i.e., feedstock harvest, preprocessing, and logistics), as well as the costs and benefits of commercial implementation. Toward that end, the objective of this study was to examine the peer-reviewed scientific literature and other commercial information sources to identify and quantify key cost data. Specifically, this project focused on seaweed harvesting, drying, densifying, and transporting. This project did not, however, examine either growth/cultivation or the subsequent processing of the dried seaweed. Those topics, while important, will be the subject of a separate paper. Go to Introduction In recent years, mariculture has become a fast growing food sectors, not just in China and the Far East, but around the world, with an annual growth rate of 4-11%. This ra

  Juniper Publishers -  Journal of Oceanography Abstract This study done in 2010-2011 through Spring, Summer, Autumn and Winter, in 32 studies from 8 transects (Astara, Anzali, Sefidrood, Tonekabon, Noshahr, Babolsar, and Bandar Turkman). In each transect, have choosen 5 stations and different depths of 5m, 10m, 20m, 50m and 100m were sampled quarterly from the zero depth (level), 10m, 20m, 50m and 100m were by Niskin sampler. Since 2005 a new species of diatoms called Pseudo-nitzschia seriata found in the southern Caspian Sea and in the Caspian Sea, adapted itself to new conditions and the ability to grow and reproduce in the environment has increased. Pseudo-nitzschia seriata is a eukaryotic cell with ability to produce Domic acid that can be harmful to aquatic and human.Due to various Physic and Chemical factors such as temperature change (change of seasons), high concentrations of dissolved nitrogen in all of these examples can effect on the toxin (Domic acid) production, then in d

  Juniper Publishers -  Journal of Oceanography Abstract In this paper we address the importance and transcendence of biodiversity surveys to detect early arrival of exotic species that could become ecological invaders. We used qualitative-intensive surveys of gastropods benthic fauna in high energy beaches as a model for the detection of exotic species. Between 2009-2010, four beaches belonging to the Venezuelan Gulf were sampled every three month through the standard transepts and quadrants methodology using a Ekman grab. We identified 105 gastropods species, 35 of which were new addition to the Venezuelan malacofauna. Ten of these species are new for the Atlantic Ocean, which means, they are introduced species. These species are: Bittium rugatum Carpenter, 1864;  Cerithiopsis bakeri  Bartsch, 1917;  Diastoma fastigiatum  Carpenter, 1864;  Odostomia  astricta Dall and Bartsch, 1907;  Odostomia  aepynota Dall and Bartsch 1909,  Odostomia  excolpa Bartsch 1912; Triphora catallinensis B
