Aquatic Science and Technology <p><em><strong>Aquatic Science and Technology</strong></em> (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 <strong><a href="">Online submission</a></strong> and Email submission (<strong></strong>).</p> <p>The scopes of the journal include: Aquaculture, Aquatic Biology, Aquatic Chemistry, Aquatic Ecology, Aquatic Environmental Monitoring, Aquatic Pollution and Remediation, Aquatic Toxicology, Conservation and Utilization of Aquatic Resources, Dynamics of Aquatic Ecosystems, Fisheries Science, Investigation and Assessment</p> Bigedu Foundation en-US Aquatic Science and Technology 2168-9148 “Notes” Morphology and Histology of the Mysticete’s Prostate and Its Implications in Male Fertility <p>The global whale population has dramatically declined in the past centuries due to anthropogenic abuse, whereas, climate change, ship strikes, entanglements, pollution, and water debris are currently making an enormous impact on the recovery of all whales on the planet.</p> <p>The prostate is recognized as the only male accessory gland in odontocete cetaceans, and prostatic pathologies have been recently described as very common in these animals. But nothing is reported about the male accessory gland in any species of mysticete. Here, we describe the topography and histology of the prostate of two baleen whales: a fin whale (<em>Balaenoptera physalus</em>) and a Bryde’s whale (<em>Balaenoptera edeni</em>) and conclude that in the mysticetes, the prostate displays the same general morphologic and histologic characteristics as in odontocetes.</p> <p>The prostatic gland of the mysticete may be a target for many pathogens that wants to spread by a sexual transition to other animals and the offspring which may have great impact on reproductive capability for the individuals.</p> Suárez-Santana C.

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.
