Maritimes Region Fisheries Service 7 Aquaculture Workshop The workshop arranged by T.G. Carey, R.D.B. and J.E. Stewart, R & D, Fisheries Service, was mostly in-service and represented an attempt to bring government people up-to-date on what was happening in government and in closely related projects. The emphasis was largely, but not exclusively, on salmonids. The prepared statements listed in the agenda were presented and in some instances were illustrated with slides. Summaries of most of these statements were prepared by the authors and have been included in the written record. Discussions provoked by the prepared statements and by other points raised by different participants have been summarized briefly and presented below largely without attribution and should be read in conjunction with the various authors' summaries. Included as well is a copy of a highly relevant letter from J.S. MacPhail, Director of Resource Development for the Nova Scotia Department of Fisheries. OPENING REMARKS - J.E. Stewart This is a particularly appropriate time to hold a workshop on aquaculture, since even to the most casual observer it has become apparent that there is a multiplicity of private, university, federal and provincial government projects going by the name of aquaculture and costing a great deal of money. With the increasing competition for research funds it is unreasonable to expect continued financing of any research area unless the participants offer evidence of doing something useful and of deriving the maximum benefit from the money spent on the various projects going to make up the whole.

    Justification for the Mitigated Determination of Non-Significance (MDNS) for Washington Department of Fish and Wildlife SEPA 19-056 and for the Approval of Cooke Aquaculture Pacific’s Marine Aquaculture Permit Application Washington Department of Fish and Wildlife (contact: Dr. Kenneth I. Warheit; [email protected]) January 21, 2020 (Erratum section 4.2.5 January 29, 2020) INTRODUCTION In January 2019, Cooke Aquaculture Pacific (hereafter termed Cooke) submitted to the Washington Department of Fish and Wildlife (WDFW) two applications: (1) an application to renew an expiring 5-year Marine Aquaculture Permit to continue to culture Atlantic salmon (Salmo salar) at Cooke's marine net- pen facilities in Puget Sound; and (2) an application for a new 5-year Marine Aquaculture Permit to transition production from Atlantic salmon to all-female triploid (sterile) steelhead trout (Oncorhynchus mykiss) at Cooke's existing marine net-pen facilities in Puget Sound. Included with these applications were Fish Escape, Prevention, Response, and Reporting Plan; Regulated Finfish Pathogen Reporting Plan; Plan of Operation for All-female Triploid Rainbow Trout1; and Plan of Operation for Atlantic Salmon Rearing. In March 2019, WDFW approved and issued to Cooke a renewal of their 5-year Marine Aquaculture Permit for Atlantic salmon, contingent on the requirement specified in EHB 2957 that farming of nonnative marine finfish in Puget Sound is valid only with a current lease of state-owned aquatic lands. At the same time, WDFW responded to Cooke's second application by informing them that before WDFW could decide on their permit application a SEPA process was required to determine the environmental effects of transitioning production from Atlantic salmon to all-female, triploid steelhead trout at their existing facilities.

It acts as the main source of funds for developmental projects in the Latin American region. Nineteen years ago, the IDB began promoting the possibilities and significance of fishery development in Latin America. The experience gained over these years indicates that financial development agencies can make contributions to the progress of this sector if they have an accurate diagnosis on the sector, including natural and human resources, institutions, government policies, infrastructure, production capacity and developmental potential. In response to the banks desire to know the present situation of aquaculture in South America, its forestry and fisheries section hired a summer intern to conduct this up- date.

  • Integrated Mariculture a Global Review. FAO Fisheries And
    ISSN 2070-7010 529 FAO FISHERIES AND AQUACULTURE TECHNICAL PAPER 529 Integrated mariculture A global review Integrated mariculture – A global review global A – mariculture Integrated This technical paper provides a comprehensive review of current integrated mariculture practices around the world in three papers covering temperate zones, tropical zones and one semi enclosed ecosystem, the Mediterranean Sea. Integrated mariculture includes a diverse range of co-culture/farming practices, from integrated multitrophic aquaculture to the more specialized integration of mangrove planting with aquaculture, called aquasilviculture. Modern integrated mariculture systems must be developed in order to assist sustainable expansion of the sector in coastal and marine ecosystems thus responding to the global increase for seafood demand but with a new paradigm of more efficient food production systems. Successful integrated mariculture operations must consider all relevant stakeholders into its development plan, there is also a need to facilitate commercialization and promote effective legislation for the support and inclusion of integrated mariculture through adequate incentives particularly considering the reduction of environmental costs associated to monoculture farming. Bioremediation of fed aquaculture impacts through integrated mariculture is a core benefit but the increase of production, more diverse and secure business and larger profits should not be underestimated as additional advantages.

  • Perspectives for Sustainable Development of Nordic Aquaculture
    TemaNord 20 TemaNord 13:546 Ved Stranden 18 DK-1061 Copenhagen K www.norden.org Perspectives for sustainable development of Nordic aquaculture Perspectives for sustainable development The Paban-Report of Nordic aquaculture Aquaculture is one of the fastest growing productions and the value of aquaculture is now about to pass the value of capture fisheries. Among the Nordic countries, Norway in particular has been able to create a large aquaculture industry with high growth rates over a number of years. The other Nordic countries have only had limited growth, but have a high unutilised potential. There is a need to identify opportunities and limitations for increased growth with due care for sustainability and environment. This report identifies seven focus areas with special potential for creation of a sustainable, com- petitive Nordic aquaculture sector. These areas are new feeds, better use and reuse of nutrients (nitrogen, phosphorus and carbon), value adding of by-products, technological and regional development, domestication of new species and reduction of energy consumption. The aquaculture sector with its strengths and weaknesses is described for each of the Nordic countries. The report is compiled on basis of contributions from a Nordic group of experts. It was presented at a seminar on Green Growth at the annual meeting of the Nordic Ministers of Fisheries in Trondheim, July 2012.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Research Papers in Economics The Innovation System of Norwegian Aquacultured Salmonids Heidi Wiig Aslesen NIFU STEP, Oslo Correspondence: [email protected] Abstract This paper is about one of the most important export products in Norway, “Norwegian salmon”, focusing especially on the innovation system of aquaculture of salmon and trout in Norway, the aim of the paper is to describe the sector in a national and global context, for thereafter highlight in particular how different aquaculture firms operate and carry out innovation by looking at what kind of external relations and interactive learning processes are involved in innovation, and as such suggesting input to policy makers on how to strengthen the sectoral innovation system, a sector with the potential to become even more knowledge intensive and innovative than today. By differentiating aquaculture according to knowledge base and degree of structured and functionally differentiated organisations, the empirical material presented in this paper shows that aquaculture firms have very different approaches to innovation; from anti- innovation strategies to strategies of being in the fore-front of innovation in the industry. The empirical material has shown that firms with very different innovation systems exists side-by-side and the overall functioning of the sectoral innovation system of aquaculture is influenced by all the different layers of firm types.

  • Biological Control of Salmon Lice
    Master’s Thesis 2020 30 ECTS Faculty of Landscape and Society (LANDSAM) Biological Control of Salmon Lice: A Critical Analysis of Knowledge Production and Development in the Norwegian Cleaner Fish Industry Patrick John Bolliger Master of Science in International Environment Studies BIOLOGICAL CONTROL OF SALMON LICE: A CRITICAL ANALYSIS Abstract The lumpfish and four species of wrasse have become important resources for cleaning salmonids of sea lice in Norwegian aquaculture. Cleaner fish’s delousing effectiveness and mortality rates in salmon cages vary dramatically due to environmental conditions, disease, and husbandry practices. While cleaner fish are portrayed as an environmentally friendly product, no post-cleaning use is made of their body parts. Thus, researchers and animal rights organisations have questioned whether the wrasse fishery and large-scale lumpfish aquaculture is justified and ethical. This case study analyses themes derived from qualitative interviews focussing on the history, knowledge production, and contestation of cleaner fish practices using a critical political ecology approach. The results suggest that despite rapid growth in their use, cleaner fish are an impermanent delousing solution. Perceptions of cleaner fish use are changing from optimism to scepticism and their use is characterised by uncertainty due to efficacy and welfare challenges. I argue that producing and using cleaner fish in Norway is contradictory in nature and constitutes a ‘socioecological fix’ of capitalism. This helps explain how salmon aquaculture’s inherent vulnerability to lice creates an opportunity for behaviour in cleaner fish to be produced, exploited, and profited on. At the same time, this process both produces and ‘fixes’ social, economic, and environmental externalities.
