Investigations into the viability of commercially available probiotics will be conducted against known bacterial pathogens, applied via appropriate delivery method in to the larviculture protocols, with resulting juveniles then challenged with known pathogens. These investigations will be combined with economic analyses to determine impacts on production efficiencies, costs, and determination of economic viability. Specific approaches include the following: 1) Conduct in-vitro trials to determine which commercially available probiotics are effective at inhibiting clinical isolates of bacteria that are pathogenic to fish. 2) Conduct in-vivo trials by applying viable probiotics, screened from Objective #1, into larviculture applications via appropriate delivery methods. Delivery methods will include dosing the water directly and/or in the larval feed. The impacts of probiotics on production variables such as survival, growth, density, and morphology will be determined. 3) Conduct additional in-vivo trials, disease challenge assay using fish from Objective 2, to determine if disease resistance will be increased in fish that have been exposed to probiotics versus those who have not. In addition to survival, other molecular or histological tools will be considered. 4) Economic analysis to determine whether application of tested probiotics are economically practical.

Progress 09/01/19 to 08/31/20
Outputs
Target Audience:The USDA-NIFA Southern Regional Aquaculture Center (SRAC) is a funding activity focused on identifying and solving problems in southern aquaculture. The ultimate audience for products developed through these funded projects include infrastructure personnel (farmers, processors, feed manufacturers, equipment manufacturers, harvesters, etc.) and consumers. The research funded through this project is made available to the research community through SRAC Annual Progress Reports, peer-reviewed journal articles, books, and presentations at professional society meetings. Audiences for SRAC factsheets, videos, and other publications include Extension Specialists and agents, educators, regulatory agencies, and potential investors. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?SRAC does not fund training and professional development directly. The individual project participants may receive training and professional development opportunities as part of the individual funded project. How have the results been disseminated to communities of interest?Detailed summaries of outputs from research and Extension activities and administrative support activities are presented in the SRAC 31th Annual Progress Report available from the SRAC website at http://srac.msstate.edu/annualprogressreports.html. These projects resulted in 20 oral presentations, 2 poster presentations, 4 Extension/Outreach publications, 4 journal articles, 5 digital products, and has supported 22 students. Scientific publications and additional journal articles resulting from research and Extension projects are reported by each participating institution. Publication and journal article lists can be found on the SRAC website. Fact sheets and videos are requested and used by RACs and Extension personnel in other regions. In addition to direct requests for printed material, fact sheets and other informational materials are accessed daily from the SRAC website by people searching for technical information. In the period from September 2017 through August 2018, 59,101 visitors came to the SRAC Publications website and accessed publications 249,581 times. These visitors came from 169 countries/territories. Since the fact sheets are also accessible through numerous other university research and Extension websites, the total usage and impact is undoubtedly several times greater. SRAC videos were viewed on the SRAC YouTube Channel 41,455 times during the reporting period. The AQUAPLANT website from September 2017 through August 2018 had 233,279 visitors that accessed 592,196 pages. These visitors came from 181 countries/territories. What do you plan to do during the next reporting period to accomplish the goals?During the next reporting period, there will be a joint meeting of the Industry Advisory Council (IAC) and Technical Committee (TC) to prioritize research and Extension needs. The IAC will initiate the project development process by identifying critical problems facing aquaculture in the region. The IAC and TC will discuss the potential impacts and pitfalls of each proposed problem area. The IAC will then prioritize problem areas and recommend the most important research and Extension needs to the Director and Board of Directors. Once an area of work has been approved, the Executive Committee will appoint a Project Writing Team to develop a Request for Pre-Proposals. These Pre-Proposals will then be reviewed by a Proposal Review Team and one proposal for each priority project will be selected for funding. After each proposal has been selected for funding, the SRAC Director recruit a Project Work Group, which consists of individuals collaborating in the selected pre-proposal and members of the Project Writing Team. The Project Work Group will prepare the project proposal, which will be reviewed by the IAC, TC, all project participants and designated peer reviewers from within the region and from outside the region. The SRAC Director will submit the project proposal and peer reviews to the Board of Directors for review and approval. The Director will prepare an annual plan of work, including all project proposals approved by the Board, and submit the plan to NIFA for approval. Pending a successful review of the project plan and budget, NIFA will notify SRAC of final approval. Letters of Agreement (subcontracts) between SRAC and participating institutions will then be prepared and forwarded for approval and execution by the authorized institutional official. Additional plans include: Prepare budgets for the Administrative Center, track administrative expenditures and obtain USDA-NIFA approval for project and budget revisions. Prepare budget reports for the Board of Directors, tracking expenditures and status of funded projects and the Administrative Center. Assist with preparation and revision of proposals for technical and scientific merit, feasibility and applicability to priority problem areas. Solicit and coordinate national reviews of project proposals. Distribute factsheets to research and Extension contacts throughout the Southern Region, other RACs, and USDA personnel. Produce and distribute the SRAC Annual Progress Report, which includes editing and proofreading the project reports. Produce and maintain the website for SRAC which provides downloadable copies of all SRAC fact sheets, the Operations Manual and Annual Reports, as well as lists of other research publications and Extension contacts in the Southern Region. Prepare and distribute Requests for Pre-proposals to research and Extension directors and other interested parties throughout the Southern Region. Respond to requests from aquaculture producers, the public, and research and Extension personnel for copies of factsheets, research publications and videos produced by SRAC and the other Centers, as well as requests for general aquaculture related information. Serve as fiscal agent to review and approve invoices and distribute funds to participating institutions as approved under the grants and as set forth in the Letters of Agreement. The next Publication project year is still in development and specific publications have not been established. The SRAC Publication Steering Committee will meet to develop next year's project.
