Uhm Phd 7315943 R.Pdf INFORMATION TO USERS This dissertation was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing pagels) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again - beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced.

  • 2012 Economic Impacts of Marine Invasive Species
    Final Report to the Prince William Sound Regional Citizens’ Advisory Council Marine Invasive Species Program Contract No. 952.11.04 FINAL REPORT: July 19, 2011 – July 31, 2012 Submitted July 31, 2012 The opinions expressed in this PWSRCAC-commissioned report are not necessarily those of PWSRCAC Project Overview Non-Indigenous Species (NIS) may specifically be classified as invasive when ecologically or economically damaging and/or causing harm to human health. We see the economic consequences of invasions in other states and regions. Alaska has not experienced significant impacts to date but examples tell us it may only be a matter of time, and all the more assured if we do nothing or little to prevent and mitigate invasions. To date, we as a state have not undertaken an economic assessment to estimate how severe an economic impact could be due to marine invasive species. Without this economic analysis the environmental arguments supporting action for an Alaska Council on Invasive Species become mute. There may be impacts, there may be environmental consequences, but a louder voice echoing the economic impacts may be required to get the ear of the Legislature. To this end we proposed to work in collaboration with the University of Alaska Anchorage’s Institute of Social and Economic Research (ISER) to assess economic benefits and costs of taking action versus no action on invasive species in Alaska. This project is a result of the Marine Invasive Species Workshop held in 2010 by the Marine Subcommittee of the Alaska Invasive Species Working Group. Workshop participants discussed the status of marine invasive species in Alaska, the state’s invasive species policies and management, and the potential impacts of marine invasive species on Alaska’s commercial, recreation, and subsistence economies.

    Perelonia et al. / The Philippine Journal of Fisheries 28(1): 33-43 January - June 2021 DOI: 10.31398/tpjf/28.1.2020A0008 RESEARCH ARTICLE A Study on the Distribution and Level of Cadmium in Scallop Bractechlamys vexillum (Reeve 1853) from the Visayan Sea, Philippines Karl Bryan S. Perelonia* , Riza Jane S. Banicod, Kathlene Cleah D. Benitez, Gezelle C. Tadifa, Bryan E. Tanyag, Flordeliza D. Cambia, Ulysses M. Montojo Fisheries Postharvest Research and Development Division – Seafood Quality and Safety Section National Fisheries Research and Development Institute, Quezon City, Philippines ABSTRACT Bivalves such as scallop Bractechlamys vexillum are considered an essential resource for livelihood and revenues in the Visayan Sea, central Philippines. To date, there are several reports that the local marine ecosystems are contaminated with heavy metals like cadmium; hence, these species are also susceptible to bioaccumulation of cadmium because they feed mainly by filtering particles from contaminated water. In recent studies, scallops are suggested to be a potential bioindicator for cadmium contamination due to their ability to accumulate and tolerate the metal. This research aims to examine the anatomical distribution of cadmium in B. vexillum and measure the relationship between shell weight and cadmium concentration. The sites for this study include Carles, Iloilo, Madridejos, Cebu, and Cawayan, Masbate. Five organs were analyzed: adductor muscle, digestive gland, gonad, gill, and mantle. The analysis for quantification of cadmium in the different scallop parts was carried out by Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES Model ICPE-9820, Shimadzu, Kyoto, Japan). Results showed that cadmium preferentially accumulates in the digestive gland, accounting for 76.39% of the total metal concentration.

  • Impacts of the Invasive Ascidian Didemnum Vexillum on Green-Lipped Mussel Perna Canaliculus Aquaculture in New Zealand
    Vol. 4: 17–30, 2013 AQUACULTURE ENVIRONMENT INTERACTIONS Published online June 18 doi: 10.3354/aei00069 Aquacult Environ Interact OPENPEN ACCESSCCESS Impacts of the invasive ascidian Didemnum vexillum on green-lipped mussel Perna canaliculus aquaculture in New Zealand Lauren M. Fletcher1,2,*, Barrie M. Forrest1, James J. Bell2 1Cawthron Institute, Private Bag 2, Nelson 7010, New Zealand 2School of Biological Sciences, Victoria University of Wellington, PO Box 600, Wellington 6140, New Zealand ABSTRACT: Biofouling can pose a significant threat to shellfish aquaculture, as fouling organisms are often strong spatial competitors that are able to reach high densities or biomass in relatively short time frames. This study investigated the potential impacts of the colonial ascidian Didem- num vexillum on cultured New Zealand green-lipped mussels Perna canaliculus at one farm in the Marlborough Sounds region. Three size classes of mussels were examined: small (20 to 40 mm shell length at deployment), medium (40 to 60 mm), and large (60 to 70 mm). Replicate 4 m mussel lines were assigned to 1 of 3 treatments: (1) ambient fouling, (2) fouling enhanced by D. vexillum fragment inoculation (in addition to ambient fouling), or (3) control lines that were kept free of D. vexillum. After 15 mo, subsections of lines (0.5 m length) were processed to determine the effects of fouling cover on mussel density within lines, as well as on individual mussel size and condition. A highly significant negative relationship was shown between D. vexillum biomass and mussel density for small mussels, and to a lesser extent for medium mussels. Values of mussel condition indices were similar across size classes and across fouling treatments within each size class.
