The business meeting was called to order by Sherry Larkin, Interim Chair (May 22, 2017):

Two members that were officers have relocated in the past year and, until they officially transfer or revise an Appendix E, new officers are needed. The following assignments were agreed upon until new elections at the 2018 annual meeting to carry the group through termination in 2019.

  • Chair: Kwamena Quagrainie
  • Vice-Chair: Hiro Uchida
  • Secretary: Sherry Larkin

To help the group re-organize, and maintain connected, conference calls were suggested. It was agreed that quarterly conference calls should begin June 2017. The secretary will organize calls via Doodle Poll. The first call will be for current members only and will include discussion of ideas for future group activities and a brainstorming session on plans to formally recruit additional members.

Diego Valderrama reminded the group of the impact flyer that was created to highlight the significance of accomplishments of W2004 (2009-2014).

The new advisor (David Thompson, dathomps@ad.nmsu.edu, New Mexico State University) was announced. Hopefully he will be able to attend, and even join one of the conference calls in 2017-18.

The meeting ended with a call to engage these related projects and collaborators during the 2017 NAAFE Forum and beyond. Follow-up discussion revolved around the special session by Anderson/Asche/Anderson under Objective 4; the project is an extension of the working group of W3004 members held prior to the 2013 NAAFE Forum. That session developed primary data for the indicators and now the FPI project has more than 100 fisheries included and the database is being extended from commercial fisheries to aquaculture and recreational fisheries, which will require new or revised measures of key metrics in order to effectively incorporate for comparison.

The group proposed and agreed to hold the 2018 W3004 meeting in conjunction with the 19th Biennial IIFET (International Institute of Fisheries Economics and Trade) Conference in Seattle, which will be held July 16-20 (https://www.facebook.com/events/1075451839231150/). There was discussion about holding a W3004 workshop prior to the conference to again support the FPI project.

Accomplishments

Accomplishments – by Objective

  1. Improve the development of seafood markets by focusing on analyses of new marketing themes, market niches, and alternative seafood products
    1. One project examined whether price premiums often observed at the retail level are sufficiently transmitted to ex-vessel prices, that is, whether fishermen are benefiting from certification programs such as the Marine Stewardship Council (MSC). This was collaborative work with Cathy Roheim (University of Idaho, W2004 member) and produced a Master’s thesis paper that was published.
    2. Another project examined the overall ‘seascape’ of seafood certifications – meant to convey information that would increase demand by consumers – using the evolution of Theory of Change over the entire supply chain. The goal was to suggest what may come next that would mitigate many of the issues currently faced by various players along the supply chain. This was a collaborative work with Cathy Roheim, Simon Bush (Wageningen Univ., The Netherlands), Jim Sanchirico (UC Davis), and Frank Asche (UF). The paper was presented at the 2017 NAAFE Forum. This project also supported (partially) a PhD student from China, who analyzed the Chinese consumer market for sustainable seafood as part of his dissertation. Preliminary results from that study were also presented at the 2017 NAAFE Forum.
    3. A current project involves a survey of Connecticut residents’ interest in and demand for Connecticut aquaculture products—specifically, oysters, clams, and seaweed. The survey involves a choice experiment and participants will be given various information treatments about the health/nutrition and environmental benefits of (local) aquaculture. The survey will launch June 2017. This is collaborative work with Tessa Getchis and Anoushka Concepcion from Connecticut Sea Grant and Miriah Kelly from UConn Extension. External grants cover parts of the work, including supervision of an MS student. Findings will be submitted to Agricultural and Resource Economics Review later this year and presented at the 2018 IIFET, AERE, and/or NAREA meetings next year.
    4. Another study investigates the potential for local oysters to command a price premium over imports. A discrete choice experiment was administered to seafood restaurant chefs to examine how they value different attributes related to price, grow-out site, freshness, and supply constancy. This effort is a joint endeavor between W3004 members from the University of Hawaii at Manoa and the University of Alaska – Fairbanks.
    5. Invasive lionfish in the Caribbean are causing concern for the sustainability of reef systems, especially in affecting the supply of fresh fish upon which small island nations depend. One project, funded by the NOAA Saltonstall-Kennedy program, seeks to assess the viability of seeking to grow a commercial fishery for lionfish in the USVI. This is a collaborative effort with Emory University (Tracy Yandle) and Georgia Southern University (Jenn Sweeney-Tookes) and involves mapping fishing areas and assessing willingness to sell and buy lionfish. Surveying was completed during the summer of 2016 and several events are being held on the islands in mid-June 2017 to share the results and train fishermen and consumers on how to catch, handle, fillet, and cook lionfish.
  2. Enhance fishery and aquaculture production by developing decision support tools to integrate management and marketing
    1. There are currently dozens of computer-based models being used to evaluate and implement Ecosystem-Based Fishery Management (EBFM)-inspired fisheries management policies (in fisheries throughout the world). All of these models rely on ad hoc and frankly indefensible assumptions for the role and behavior of fishermen, i.e., the top predator in most ecosystems. One recent paper from this project entitled, “Ecosystem-Based Fisheries Management under Rational Ecological-Economic Equilibrium” incorporates state-of-the-art principles for modeling economic behavior in regulated environments. The methodology introduced in the paper generates robust predictions of ecological and economic outcomes of management interest (harvests, discards across time and space) within competitive markets and importantly, under rational expectations equilibrium behavior of fishermen. This work represents a fundamental departure from currently available approaches and is expected to significantly advance EBFM.
    2. The production of Pacific white shrimp (Litopenaeus vannamei) in indoor facilities has gained a lot of interest in the Midwest and attracts premium prices. Fish farmers are benefiting from the local foods movement and consumers’ willingness to pay for locally grown food products. However, the economics of indoor shrimp production is not well understood and the current high prices are not sustainable. Workshops were conducted on indoor shrimp production with experts in the field speaking on various topics related to the subject. Then, a study was conducted to assess the profitability of indoor production of the marine shrimp in the Midwest, under different production scenarios that involved stocking size, market size, survival rate, and selling price.
    3. Working to advance aquaculture as a business involves research into different production systems with an attempt to increase efficiencies in production while decreasing cost of production. Working with a variety of aquaculture producers, three projects are investigating the economics of (i) indoor greenhouse aquaculture of tilapia and using the fish effluent to fertigate vegetable production; (ii) developing a new intensive production technology called the in-pond raceway system; and (iii) development of vaccines to reduce disease mortalities in the US farm-raised catfish industry. Graduate students are being funded to support each project and are presenting results in journals and at aquaculture association meetings.
    4. Traditional fishpond aquaculture in Hawai‘i has declined since global trade provided access to cheaper imports, but stakeholders in Hawai‘i hope to develop a local oyster farming industry. This study investigates the production economics of a fishpond-based oyster farm by 1) assessing profitability, 2) determining sensitive input parameters, and 3) using stochastic modeling to determine the likelihood of different economic outcomes. Findings showed a marginally negative profit, with the bulk of operating costs from labor. Decision reversal analysis indicated the model farm can be profitable with an increase in market price from US $1.25 to US $1.35 per oyster or a decrease in mortality rate from 50% to 45.9%.
    5. The overall goal of a rather unique sub-project (for W3004) is to develop a methodology for assessing the socioeconomic impacts of aquatic animal diseases and estimate the adverse economic impacts. Specifically, one project aims to measure forgone (i) output or sales by businesses within the economic region affected by the disease outbreaks; (ii) personal income including wages and salaries and proprietors' income or income from self-employment from fish farming and related businesses; (iii) employment in fish farming and related businesses; (iv) contribution made to the value of fish products at each stage of harvesting, processing and distribution; and (v) tax revenues associated with harvesting, processing and distribution of fish products. The project is a result of an international working group built upon an existing relationship with FAO (Food and Agriculture Organization of the United Nations) to assist with methodology selection and to conduct a socioeconomic assessment baseline study of the impacts of Epizootic ulcerative syndrome, which is a type of fungal infection, affecting aquaculture production in Zambia and Zimbabwe. The group held a three-day workshop in Durban, South Africa on October 24-26, 2017 was attended by 28 participants coming from the African continent, Italy, Sri Lanka, Bosnia and Herzegovina, Norway, Canada and United States (including a W3004 member).  
  3. Increase the organizational and institutional efficiency of the aquaculture and fishery sectors by analyzing the regulatory environment and developing ideas to support the sectors
    1. A recently completed project investigated the effect of information on health benefits and risks of consuming seafood. An experimental auction method was used to actual consumers to collect data. Key findings include that consumers react more readily to health risk information (e.g., mercury contamination in swordfish) while almost no reaction to health benefit information (e.g., omega-3 in salmon). The paper was recently published in AJAE. This was a collaborative work with Cathy Roheim (U of ID) and Robert Johnston (Clark U in MA). The sequel paper is currently under development led by a PhD student as part of his dissertation. Preliminary results of that second paper was presented at 2017 NAAFE Forum.
    2. An Aquaculture tour was conducted that connected foodservice professionals with Indiana fish producers. This is important because much of the fish produced in Indiana is sold live to ethnic markets, direct to consumers on farms, and in limited amounts, to the food service sector. With the increasing emphasis on eating local foods and knowing where your food comes from as part of a healthy lifestyle, there was an opportunity to increase awareness and improve perception of the aquaculture industry in Indiana foodservice businesses. The tour provided chefs and culinary professionals the opportunity to interact with fish producers at their farms to learn about aquaculture practices and products in Indiana. The tour resulted in new business contacts and markets for the aquaculture industry.
    3. An ongoing project is examining the impact of foodborne disease outbreaks in the context of oyster farming. Oyster farmers face two kinds of foodborne disease-related risks: an outbreak risk in his own farm, and negative influence they face through markets when an outbreak occurs in a neighboring farm. This project focuses on the latter risk, and asks what oyster farmers can do to shield themselves from such adverse impacts. Data collection is scheduled to begin in June 2017.
    4. Improving the regulation of quota-managed commercial fisheries is a universal goal. Theoretical and empirical evidence of the impacts of flexibility provisions in multiple-species catch shares fisheries is currently unavailable. Regulators are nonetheless implementing flexibility provision in quota-managed fisheries without knowledge of their implications. The paper titled “Quota flexibility in multi-species fisheries” fills an important gap that will improve the design of catch-share regulatory systems.
  4. Improve the understanding of how infrastructure investment, location, and sector organization affects the stability of both the aquaculture and capture fishery industries.
    1. Fishery Performance Indicators: the paper based on the first round of FPI implementation began under W2004, led by collaborators Jim Anderson (UF, past member) and Chris Anderson (UW, past member), was published in online journal PLoS One.
    2. Developing the economic impact of recreational and commercial shellfish sector is a top priority in the northeast U.S. region. IMPLAN is being used for this analysis. A project has already completed two surveys of shellfish commissions to obtain the numbers of permits, associated product sales, and agency budgets for managing recreational shellfishing. Preliminary economic impact estimates of employment, output and value added have been generated and are now being reviewed.
    3. Workshops were conducted on aquaponics to practitioners. Aquaponics has significant appeal because of the sustainable aspect of producing vegetables from the waste product from the fish, lending itself to diversified, small-scale, local niche producers. The practice of aquaponics is technically difficult as it combines two separate rearing strategies of aquaculture and hydroponics. The 1-day workshop brought together hydroponics practitioners and experts in food safety of vegetables, fish production, pest control in aquaponics, sustainable horticultural systems, hydroponic crops, greenhouse structures, and economics and marketing. The presenters provided latest research results in their various fields relating to issues associated with aquaponics. As a result, current and potential aquaponics practitioners were educated on structures for an aquaponics operation including greenhouses; potential fish and vegetable combinations and their requirements; pest control in green houses; types of aquaponics production systems; economics of aquaponics; marketing of fish and vegetable products; and food safety and handling of produce. Aquaponics practitioners also had the opportunity to network and benefit from one-on-one interactions with the scientists.

Impacts

  1. Scientists developed innovative new state-of-the-art models that better incorporate economic behavior in regulated environments. These models will predict ecological and economic outcomes of management interest (harvests, discards across time and space) within competitive markets and importantly, under rational expectations equilibrium behavior of fishermen. This new approach is expected to significantly advance the implementation of Ecosystem-based Fishery Managemetn (EBFM) practices and policies worldwide.
  2. University of Hawai'i researchers worked with local stakeholders to assess the viability of local oyster farming industry as an alternative to imports. Findings indicate that a $0.10 per oyster increase in market price or a 4% decrease in oyster mortality rates would be needed for farmers to overcome high labor costs and turn a profit.
  3. Consumers are regularly exposed to information on the health benifits and risks of seafood consumption, but producers aren't always sure what messages consumers react to. New research by University of Idaho and Clark University scientists on actual consumers shows that they react more readily to health risk information (e.g., mercury contamination in swordfish) while almost no reaction to health benefit information (e.g., omega-3 in salmon). This information can be used to refine seafood marketing, increase consumption, and thus producer profits.
  4. In Indiana, a small percentage of locally-farmed fish is sold to the food service sector. However, consumers are increasingly demanding locally-grown products in restaruants. To increase awareness and improve the perception of the Indiana aquaculture industry, chefs and other culinary profssionals were given a tour of farms in the state. The tour resulted in new business contacts and markets for the aquaculture industry.
  5. Aquaponics is the process of simultaneously growing vegetables from fish waste products. The practice is appealing to small-scale, niche producers who can market sustainably-grown products. However, aquaponics is a technically difficult process because it combines both aquaculture to raise fish and hydroponics to raise vegetables. Scientists held a 1-day workshop and brought together hydroponics practitioners and experts in food safety of vegetables, fish production, pest control in aquaponics, sustainable horticultural systems, hydroponic crops, greenhouse structures, and economics and marketing. The presenters provided latest research results in their various fields relating to issues associated with aquaponics. As a result, current and potential aquaponics practitioners were educated on structures for an aquaponics operation including greenhouses; potential fish and vegetable combinations and their requirements; pest control in green houses; types of aquaponics production systems; economics of aquaponics; marketing of fish and vegetable products; and food safety and handling of produce. Aquaponics practitioners also had the opportunity to network and benefit from one-on-one interactions with the scientists.
  6. Findings by Georgia researchers indicate that P. ananatis strains pathogenic to onion possess a specific-plasmid borne gene cluster (OVR A-D) that majority of the non-pathogenic strains lack. These regions can be utilized for designing specific diagnostic assays helping in accurate diagnosis of pathogenic P. ananatis strains. Susceptible growth stages of onion that can cause bulb symptoms were also identified and further investigations indicate that chemical treatments with Kocide 3000 at these stages can greatly reduce bulb infection. However, in situations with thrips infestation, any chemical management against P. ananatis would be ineffective. Hence, rigorous thrips management is required for effective management of P. ananatis with bactericides.
  7. Participating New York growers increased adoption of both insecticide resistance management strategies, with a 39% increase in following an appropriate rotation of insecticide classes and a 42% increase in using the action threshold from 2015 to 2017. Onion growers who followed the action threshold successfully controlled onion thrips infestations, and applied 2-4 fewer insecticide applications compared with those growers who did not use the action threshold. Cost savings from using the action threshold recommendations averaged $42/acre in 2016 and 2017.
  8. In 2013, Cornell confirmed that SLB was the cause of excessive leaf dieback and onion plants dying standing up. In 2014, via an on-farm fungicide trial, Hoepting identified that effective management of SLB was imperative when managing DM, because SLB readily invades leaf tissue once it has been attacked by DM and the resulting DM-SLB complex was more aggressive than ever with the new form of SLB. Collaborative work between Hoepting, Pethybridge and Hay revealed that SLB had developed resistance to FRAC group 11 fungicides; fungicides that were once top performing products had become completely ineffective. After learning this, onion growers no longer wasted $25 per acre per spray on products that did not work. In 2017, onion growers reported being very satisfied with their ability to manage leaf diseases in a year when conditions were very favorable for disease, thanks to their adoption of Hoepting’s considerably revamped fungicide recommendations to include new fungicides that effectively control the new aggressive form of SLB. Today, onion growers proudly know which resistance groups different fungicide products belong to and how many sprays they may make before rotating to a different resistance group. In 2017, out of the 174 individual fungicide applications made in 20 spray programs representing the majority of CVP onion acreage, an outstanding 99% followed rotation restrictions and maximum use rates for best fungicide resistance management practices to ensure their useful longevity.
  9. Pennsylvania onion growers are shifting from producing onions on standard black plastic mulch to reflective silver mulch, which can significantly reduce soil temperatures and therefore losses due to center rot. In one on-farm trial, the marketable onion yield on silver mulch was over three times that of black plastic. The incorporation of silver plastic into the integrated pest management toolbox provides growers with another tactic that they can employ to reduce losses due to bacterial disease.
  10. The WSU Extension Commercial Vegetable program determined the best timing and application methods for new narrow-spectrum insecticides, which often are slower acting than previously used broad-spectrum insecticides and would be ineffective if used in the same manner. The new insecticides are applied at lower rates and are safer for the environment and non-target organisms than the older insecticides. Additionally, the improved application methods (applying via drip or center pivot irrigation) are less expensive and more effective than foliar applications. Narrower spectrum insecticides now account for greater than 60% of insecticide applications in the Columbia Basis. Furthermore, producers have shifted from using broad-spectrum insecticides early in the season to using them late in the season, or not at all in order to preserve beneficial insects in onion fields.
  11. More than 80% of the onion growers in Washington have altered their IPM strategies for managing thrips in onions as a result of research conducted by WSU Extension. Studies showed that when the most effective insecticides were utilized in thrips management programs in onions, yields increased by 25%. A 25% increase in onion yield translates to at least $2,400 more in net profit per acre for growers who use these treatments, using the 2015 onion market value. With 24,000 acres of onions in WA, if 20% of users implement these changes, the WA onion crop value would increase by $11.5 million annually.
  12. The very significant benefits to onion growers resulting from research and extension by T. Waters and L. du Toit’s programs over the last 10+ years, including work directly related to the W-1008, W-2008, and now the W-3008 multistate projects, increased awareness among onion producers, packers, and shippers of the need to support onion research. As a result, the Columbia Basin Onion Research Commission was formed in 2016, based on a voluntary contribution of $5/acre to support research efforts in the Columbia Basin of central Washington and northcentral Oregon, where ~24,000 acres of onion bulb crops are grown annually. This has equated to approximately a $100,000/year new investment in funding for regional onion research and extension, with the first year of funding in 2017.
  13. An increasing number of onion farms in the Columbia Basin are using microbial inoculants such as AMF in an attempt to increase environmental sustainability of their production practices and, potentially, reduce the reliance on soil fumigation, pesticide applications, etc. However, the lack of independent data on efficacy of these products has results in fairly widespread use of some products that have not provided an evident benefit to the crops. Feedback from onion growers who have participated in the arbuscular mycorrhizal fungi (AMF) research project by du Toit and Waters indicated significant savings to some farms that were using liquid formulations of commercial AMF inoculants that this project demonstrated did not cause any increase in AMF colonization of onion roots compared to granular formulations. One farm alone indicated that the results have saved the operation $50,000/year, demonstrating the tremendous value of grower-cooperator trials, even when the results indicate a product is not providing benefits.
  14. Research trials on Rhizoctonia stunting in the Columbia Basin identified some highly effective management practices that significantly reduce the impact of this disease. Onion crops on coarse, sandy soils can average ~3% stunted patches. The average center-pivot irrigated onion crop is valued at a minimum of $500,000, 3% of which is $15,000. Even if only one-quarter of the ~200 onion fields in the Columbia Basin experience Rhizoctonia stunting, $15,000 x 200/4 = $750,000/year in yield loss to Rhizoctonia stunting that has been prevented as a result of growers implementing the management practices developed as a result of this research.
  15. Onion thrips research projects have identified the most effective insecticides and proper use patterns for these products. Producers that utilize this information can achieve an average 10% increase in crop yield via increased onion bulb size. It is estimated that at least half of the producers utilize this information. As such, each season, $5 million worth of onion crop is preserved by using the proper insecticides and timing of those products.
  16. In the Treasure Valley, Oregon State University and Industry partners developed the Pest Management Strategic Plan (PMSP). It is benefiting the industry by 1) providing regulators with information on actual pest management practices and therefore reducing errors in formulating risk assessments; 2) documenting stakeholder needs to support funding requests; and 3) providing information for growers to facilitate their transition to alternative pest management practices. These benefits will help assure the sustainability of onion production in the Treasure Valley.
  17. In Oregon, new compounds were identified that can be used to induce white rot sclerotia germination and reduce inoculum prior to planting. The identification of dose x treatment interactions will inform decisions on treatment-rate combinations to test in future studies. Field trials demonstrated that the combined use of sclerotial germination stimulants to reduce initial inoculum levels and in-furrow applications to suppress white rot in-season could form the basis of an IPM approach for white rot.
  18. In New Mexico, if the new inoculation protocol developed by New Mexico onion breeder, proves successful at identifying onion bulbs that are resistant to Fusarium basal rot (FBR), than FBR resistance will finally be realized and the protocol could be used by other onion breeding programs to develop FBR resistant cultivars.
  19. In Utah, more onion growers are getting soil tests done prior to planting rather than just applying a set amount of fertilizer regardless of what is present in the soil. Research by Dan Drost and Diane Alston showed that thrips populations are often higher on onions grown with high nitrogen levels and Claudia Nischwitz showed that potassium levels can affect IYSV symptom expression.
