Carole Shortal 1 Assistants: Douglas Garbini, Michael Torchia Secretary: Oeborah Kearse FOREWORD This publication is a collection of papers accepted for presenta- t1on at the International Conferenceon Design, Construct1on and Operation of ConanercialFishing Vessels. Forty papers are included; One of these "Developmentof a Sail Assisted FRPFishing Canoefor the Comoros"by Tokuzo Fukamachidid not arrive in time for presentation at the Conference,but is considered to be of sufficient importance to be included in this collection. There were 112 registrants from eighteen countries at the Conference. That and the generally high quality of the papers given confirmed that the time was right for a techn1cal meeting of naval architects. shipbuilders, fishermen, economists and other social sc1ent1sts, governmentand inter- national officials, in order to update developments in the field. This had not occurred in such a generalized manner since the third and last World Fishing Boat Conference organized by the U.N. Food and Agriculture Organization in 1967. That series of conferences led to steady and marked developmentin the technology of fishing vessel design, construction and operation, and 1t was fitt1ng that Jan-Olof Traung, organizer of those Conferencespresented a paper here which traces fishing vessel improvements since 1950 and looks to the year 2000. During the past ten years, rapid changes have occurred worldwide in the economic climate surrounding fisheries and fi shi ng operati ons due to factors such as ExtendedJurisdiction and the energy crisis . As a result fishing vessels are presently in a phaseof rapi d developmentand change,especially i n terms of energy consumptionand fi shing systems to meet the changing situation. This collection of papers is illustrative of the changes occurring, e.g., the return to sails as a means of reducing fuel consumption, the increasing extension of oil product1on into fishing areas, and the effect on f1shing industry operations of changing demands for waterfront use. Conferenceparti c1pants were asked to vote for the best paper each day, and for the best student paper. The three best papers in the overall category were: "Fishermenand Oil MenWorking together in the North Sea" by Alan Wilson, "A Rev1ewof SomeRecent Stab1lity Casualties Involving Pacific NorthwestFishing Vessels" and "ModelTests of DynamicResponse of a Fishing Vessel" both by Bruce Adee, and "Particular Needsof Fishing Vessels for Use in The DevelopingWorld" by Alejandro Acosta, Theophilus Brainerd, Bambang Pr1yono,Norbert Simmons,and RajapaksaDon Warnadasa . Best StudentPaper awardwent to DouglasMcGuffey who presented the paper "Effect of Loadingon F1shing Vessel Stability - A Case Study". In order to bring within boundsthe invnenseamount of material contained in the original papers, it has been necessaryto undertakesome edit1ng. In undertaking this task, 1 attempted to ma1ntain the authors' text and removeonly supporting mater1al and illustrations which did not appear ta be essential. However, I am sure that some authors will be disappointed; to them apologize, and accept full responsibility, emphasizing only the necessity of reducing the material to a publishable amount. 111 TheConference itself wouldnot havebeen possible without the supportof the sponsoringorganizations, and the dedication and hard workof the coordinatingcommittee and conference staff. all of whomare listed else- where. Weowe them a special thank you. Theauthors, sessionchai rmen, and the participants were the flesh and backboneof the wholeaffai r, andwere the ingred1entsof the successwhich they achieved so well. My thanks to them all. I wouldespecially like to acknowledgethe work of TomLeahy, Directorof Coneunicationsand Publ1cations for the Florida SeaGrant College Program.It 1s mainlythrough his efforts that publicationof thesepapers has materialized.

  • Environmental Management Plan
    Environmental Management Plan Exigrade Feeds Pty (Ltd.) Luderitz, Namibia Endorsed By: Jacobus Smit Endorsed By: Operational Director Signature: ____________________________ Date: 1/06/2019 ENVIRONMENTAL MANAGEMENT PLAN Exigrade Feeds, Luderitz EXECUTIVE SUMMARY Exigrade Feeds Pty Ltd is an existing fishmeal plant, situated on the premises of Pescanova Seafood factory in Luderitz, Namibia. The aim of this Environmental Management Plan (EMP) is to identify and address any environmental risks associated with the facility. As the facility is within an industrial area in the Fishing Harbour of Luderitz, it is surrounded by similar industrial facilities. Due to the nature and location of the development, impact can however be expected on the surrounding environment, see summary of potential impact below. Regular environmental performance monitoring will continue and be updated on an continues basis, to ensure compliance and that corrective measures be taken if necessary. The fishing industry is one of the biggest contributors to the Namibian economy and is a major contributor to employment in the coastal area. The existing operations at Exigrade Feeds is contributing to the local economy by increased productivity and value addition, through continued employment, and by providing opportunities for other local businesses for service delivery. The major concerns related to the operational activities at the Exigrade Feeds premises are that of air quality, waste production, fuel storage and consumption, and surface water impacts. All relevant local regulations and accepted best practices should always be adhered to. Noise and air pollution should always meet the minimum requirements to prevent air pollution and not to cause a nuisance to nearby receptors.

  • Fishing Gear Types Single Boat Midwater Otter Trawls
    Food and Agriculture Organization of the United Nations for a world without hunger Fisheries Division Fishing Gear Types Single Boat Midwater Otter Trawls Midwater Otter Trawls ISSCFG code: 03.21 – standard abbreviation: OTM Characteristics Overview A midwater otter trawl is a cone-shaped net which is towed in mid-water. It consists of a cone- shaped body, normally made of four panels, ending in a codend and the net has lateral wings extending forward from the opening. The horizontal opening is maintained by otter boards. Floats and/or sailkites on the headline and weights on the groundline provide for the vertical opening. Large modern midwater trawls are rigged in such a way that the weights in front of and along the groundline provide for the vertical opening of the trawl. The cable transmitting acoustic signal form the net sonde might also provide a lifting force that maximize the vertical trawl opening. To reduce the resistance of the gear and achieve a large opening, the front part of the trawls are usually made from very large rhombic or hexagonal meshes. The use of nearly parallel ropes instead of meshes in the front part is also a common design. The largest mesh sizes used so far are 128 m and, on modern large midwater trawls, approximately three quarters of the length of the trawl is made with mesh sizes above 400 mm. Accessory Equipment Hydrodynamic designed otter boards are used for midwater trawling. The fishing depth is usually controlled by means of a netsounder (netsonde) or depth recorders. As for other types of Trawls, catch sensors can be installed in the codend to give information about the amount of caught fish.

Bill Walk- er sent a letter asking U.S. Commerce Secretary Penny Pritzker to declare a fishery disaster for parts of the state experiencing poor pink salmon harvests this season. Walker also directed staff to promptly consider payment waivers for pink salmon fishermen holding state loans. Observer safety review • Page 6 A disaster declaration potentially could result in millions of dollars in federal relief for Alaska’s fishing industry. Alaska isn’t the only state hoping for help after a tough fishing season. California is seeking a federal disaster declaration for its crab fishery, which was hobbled last season due to an algae-related marine toxin. For sure, Alaska pink salmon fishermen had a miserable year. The state- wide harvest of about 38 million pinks was far below the preseason forecast of 90 million. Walker requested a disaster declaration for two areas that historically have Salmon wrapup • Page 8 produced large volumes of pink salmon – Prince William Sound and Kodiak. He also included two minor fisheries in his request – Chignik and Lower Cook Inlet. Curiously, the major Southeast Alaska fishery was not included in the governor’s request, even though Southeast likewise had a subpar pink salmon harvest this year.
