Aquatic Science and Technology <p>Aquatic Science and Technology (ISSN 2168-9148) is a peer-reviewed international scientific and open access journal published by Bigedu Foundation. AST's primary goal is to publish original research papers and review articles dealing with aquatic systems (marine, wetlands, and freshwater systems) and their boundaries. It is published in online version which is free to access and download. The journal accepts Online submission and Email submission. All manuscripts and any supplementary material can be submitted via the journal’s online submission or email to</p> <p><strong>AST is included in:</strong></p> <ul> <li><a href="" target="_blank" rel="noopener"><strong>ERA</strong></a></li> <li><a href=";query=2168-9148">Genamics JournalSeek</a></li> <li><a href=";user=QnVzB_wAAAAJ">Google Scholar Citations</a></li> <li>Lockss</li> <li>PKP Open Archives Harvester</li> <li><a href="">SHERPA/RoMEO</a></li> <li>The Standard Periodical Directory</li> <li>Worldcat</li> </ul> <div><strong>Areas include but are not limited to:</strong></div> <div> <ul> <li>Aquaculture</li> <li>Aquatic Biology</li> <li>Aquatic Chemistry</li> <li>Aquatic Ecology</li> <li>Aquatic Environmental Monitoring</li> <li>Aquatic Pollution and Remediation</li> <li>Aquatic Toxicology</li> <li>Conservation and Utilization of Aquatic Resources</li> <li>Dynamics of Aquatic Ecosystems</li> <li>Fisheries Science</li> <li>Investigation and Assessment</li> </ul> <p><strong>Paper Selection and Publication Process</strong></p> <div id="additionalHomeContent"> <p>a). Upon receipt of paper submission, the Editor sends an E-mail of confirmation to the corresponding author within 1-3 working days. If you fail to receive this confirmation, your submission/e-mail may be missed. Please contact the Editorial Assistant in time for that.<br /><br />b). Peer review. We use a double-blind system for peer review; both reviewers’ and authors' identities remain anonymous. The submitted manuscript will be reviewed by at least two experts: one editorial staff member as well as one to three external reviewers. The review process may take four to ten weeks. In some rare cases, according to the recommendations from editors and reviewers, a second round of peer review may be initiated. <br /><br />c). Notification of the result of review by E-mail.<br /><br />d). The authors revise paper and pay an Article Processing Charge (100USD).<br /><br />e). E-journal in PDF is available on the journal’s webpage, free of charge for download. We aim to post articles online within 3 weeks of acceptance.</p> <p><strong>NOTE:</strong><br />The publisher and journal have a policy of "Zero Tolerance on the Plagiarism". We check the plagiarism issue through two methods: reviewer check and plagiarism prevention tool ( All submissions will be checked by iThenticate before being sent to reviewers.</p> </div> </div> Bigedu Foundation en-US Aquatic Science and Technology 2168-9148 Evaluate the Effect of Using Source of Nitrogen (Soaked Brown Lentils) on Chemical Composition for Marine Microalgae Nannochlorpsis oceanica <p>Microalgae culture media must be efficient, give high growth, meet micro-requirement, and be available. The effect of different levels of brown lentil infusion and use at [25, 50 and 75%] levels on the chemical composition (protein, carbohydrates, fatty acids, and amino acids) in <em>N. oceanic </em>was evaluated. Compared to the standard F/2 Guillard. The obtained results indicated that the chemical components of <em>N. oceanica </em>were affected by these levels. The highest protein and carbohydrate content and the highest EAA content (55.92%) were obtained using OB3 medium (75% SBL) compared to the control group (100% F/2). The highest biomass production was obtained in OB3 medium. The highest TSFA and USFA were recorded for <em>N. oceanica</em> by the OB3 mean.</p> <p>The present study recommended that it is possible to use microalgae grown on OB3 and OB2 medium as a lipid and protein inducer in aquaculture.</p> Ali M.
