Workshops


Fish Histopathology Workshop

Fish histopathology workshop is planned for Sunday before the conference. The workshop will start with the keynote speaker, Dr Jeff Wolf. The keynote presentation will be followed by a few talks by invited speakers who will each present a case study, including pathology and differential diagnoses. These presentations will focus on SKIN.

We are inviting Expressions of Interest from anyone attending (and registered for) the workshop for presentations on the organ of interest (skin). The Expression of Interest should have a brief description of the case and one picture as well as name and affiliation of the presenter. Please email yourExpression of Interest to B.Nowak@utas.edu.au. As we are planning to digitise all slides we will need histology blocks to be sent to UK for processing by June, so once your presentation is approved you will have to post the block (or blocks), which will be returned at the workshop. We are hoping that these presentations will result in some discussion.

In the last session we will be providing an opportunity for the participants to present images of pathology of unknown origin or unidentified structures. These presentations should still include background but the focus should be on the unknown structure/feature and the talks are expected to be short. (appr. 5 minutes). They will not be included in the final workshop materials. To be able to plan the structure of the workshop and to calculate the time needed, please also send a message to Barbara Nowak if you would like to give one of these short presentations.

Validation of diagnostic tests for infectious diseases of aquatic animals - tips and traps

Diagnostic validation (including estimation of sensitivity and specificity) is an important prerequisite for evaluation of a test’s fitness for purpose (e.g. surveillance, confirmatory diagnosis). Workshop participants will get the latest information on validation strategies for tests such as multiplex PCR, including how best to design and report test accuracy studies in peer-reviewed publications. In the hands-on computer session, participants will have the opportunity to analyze results of test accuracy studies in aquatic animals and get guidance on the evaluation of sensitivity and specificity when the reference test is imperfect. The workshop leader is Dr. Ian Gardner (left panel) from the Atlantic Veterinary College, University of Prince Edward Island, Canada. Ian has 25 years working in the area of test validation and interpretation of test results in both individual animals and populations of animals. Dr. Peter Mohr (right panel), Leader of the Aquatic Diagnostic Capability Team at the AAHL Fish Diseases Lab at the CSIRO, Australian Animal Health Laboratory in Geelong, will co-lead the workshop providing vital insights on PCR validation from a lab perspective.

Workshop topics (9:30h – 17:30h) – participants should bring a personal computer

  • Background including the World Organisation for Animal Health (OIE) pathway for test validation in the context of fitness for purpose; role of OIE reference labs, reasons for failure of validation studies
  • Laboratory experiments for validation of assays including singleplex and multiplex PCR and new technologies
  • Design of studies for field validation using naturally-occurring disease, and how to get the most from experimental challenge trials, and use of reference samples of known infection status
  • Statistical guidance for test validation studies, and hands-on session for analysis of data including strategies when the reference test is imperfect
  • Reporting test validation studies following the STRADAS-aquatic guidelines
  • Accuracy of pooled vs. individual animal testing: what experiments are needed to validate pooled tests?
  • Question and answer session including discussion of participant data and other diagnostic issues

Biosecurity Workshop

Developing a Biorisk Assessment System for Aquatic Pathogens

There is not a unified system to classify aquatic pathogens in terms of biorisk. One of the consequences is that aquatic organisms are classified for shipping using the criteria developed for terrestrial animal pathogens. Under the Hazardous Materials Regulations, Vibrio splendidus requires shipping as a UN2900, Category A Infectious Substance – using the same stringency as for Peste des petits ruminants virus or Foot and mouth disease virus. This results in restricted and expensive shipping which may not be necessary and could hamper research activities.

The aim of this workshop is not to classify aquatic pathogens. Rather it is to agree criteria under which aquatic microorganisms can be assessed and scored, such as survival time under different environmental conditions, infectious dose, susceptible species, background levels in the aquatic environment, etc. In this way, a benchmark is established against which to test and rank existing or newly discovered aquatic microorganisms. It is anticipated that in the future, this could provide the basis for developing a biorisk classification framework which is applicable to all aquatic microorganisms.

From this workshop, suggestions for prioritising areas for research and future collaboration will be generated. In fact the information gathered for identifying such listing criteria would assist researchers and research managers in focusing their activities on aspects where a significant knowledge gap has been highlighted.

In order to facilitate the discussions, preliminary questionnaires will be distributed several weeks in advance of the workshop to assist attendees in the preparation of pertinent background information.

Preparing for an effective poster session: content, style and interactions

Preamble

Despite the key importance of posters as a means of communication scientific research, particularly at large conferences, many posters fail to communicate in a way that is effective, informative, and inspiring. In this workshop we will share key recommendations for content and style of the poster, and for having an enjoyable and productive dialogue with fellow investigators who visit the posters.

Workshop Topics

We will consider:

  1. The poster session as a key mechanism for scientific communication, comprising the poster itself and the interactions between presenter and audience; the importance of preparing for both parts!
  2. Content: key topics to present, how to determine what to include, what to exclude
  3. Style: the reader’s perspective (visual and knowledge), layout, text, images (graphic and photographs), colours, fonts
  4. Interactions: how to have an interesting and productive dialogue with your audience
  5. Recommended resources – print and electronic

Workshop Format

The workshop will mix didactic elements, individual exercises, and small group work.

Workshop Materials

Participants will receive lecture materials, hardcopy worksheets, and checklists for effective poster preparation and interactions.

Organizers

The workshop leaders are Dr. Barbara Nowak and Dr. Sarah Poynton. Dr. Nowak is Associate Editor of the Journal of Fish Diseases, and a member of the editorial boards for a number of other journals. Dr. Poynton is a reviewer for a diversity of aquatic animal health journals, teaches scientific and biomedical writing, and is a freelance editor.

Dr. Nowak and Dr. Poynton have taught the well-attended EAFP student workshops on scientific publishing in Las Palmas in 2015, and on titles, figures and tables in Belfast in 2017.

Duration

Two hours.

Co-infections and multiple stressors in fish

Farmed and wild fish populations are typically exposed to multiple physical, chemical and biological stressors.

The cumulative impact of co-infections between parasites, bacteria, viruses and (a)biotic environmental pressures may trigger complex interactions, eliciting different pathological and immunological outcomes than classically assessed in highly controlled host-pathogen interactions. New studies specifically focus on the impact and dynamics of heterogenous co-infections affecting fish, both in salmonid and non-salmonid species.

Furthermore, cross disciplinary studies attempt to measure the impact of environmental stressors in modulating the host response to pathogens. Scientific advances are needed to improve fish stock management, reduce pressure on natural populations and to design more efficient vaccination strategies and diagnostic tools.

This EAFP-promoted workshop aims to raise awareness of ongoing research on the interaction between multiple infectious agents and (a)biotic environmental stressors to foster new studies and collaborations.

The workshop will be opened by Dr Mark Fast, from Atlantic Veterinary College at UPEI in Canada, with a keynote talk on “Pathological synergies in co-infecting pathogens are impacted by exposure order, and host response to initial infection”.

We encourage researchers to join the “Co-infections and multiple stressors in fish” EAFP workshop, contributing with oral presentations and flash poster presentations. A joint article on this workshop will be published in the EAFP Bulletin.

This is an open workshop, organised by Bartolomeo Gorgoglione (from MSU, USA), Christyn Bailey (from FIWI, Switzerland), Laurent Bigarré (from ANSES, France) and Olga Haenen (from WBVR, the Netherlands). For additional information, please contact Dr. B. Gorgoglione.

Vivaldi Project:
Exchange session on the VIVALDI project


09 September 2019 - 16:00-18:30

This workshop aims at crossing experiences from the VIVALDI project with research conducted overseas by members of the VIVALDI expert advisory panel. What can be done to detect the emergence of diseases as early as possible? How can we anticipate on these diseases? Combining microscopy, new sequencing tools and environmental approaches can bring new perspectives and will be discussed by the participants to the workshop.

About the VIVALDI project

The European shellfish industry is a major contributor to global production of marine bivalves. Its success depends a great deal on high environmental quality and susceptibility to mortality events, often linked to pathogenic organisms such as viruses, bacteria and parasites (protozoa). In this context, the European project VIVALDI is developing tools and approaches with a view to better preventing and controlling marine bivalve diseases. 21 partners, research institutes, universities and SMEs, from 10 countries in Europe and beyond, cooperate in VIVALDI within 6 scientific work packages, with the same objective of improving the competitiveness and sustainability of the shellfish industry.


This project has received funding from the EU’s Horizon 2020 Research and innovation programme under grant agreement N° 678589

The farming of sea bass and sea bream is an important productive sector in the Mediterranean, significantly contributing to the local economy and job creation in rural and coastal areas. Sea bream and sea bass are by volume the third and fourth most farmed fish species in the European Union (EU). However, in recent years, there is a growing concern regarding the lack of growth and improvement in Mediterranean Marine Fish Farming (MMFF) which covers the majority of sea bass and sea bream production. For the last decade, overall production in the EU has remained stagnant and at present the industry is under a range of pressures, including technical, market-oriented, legislative and financial issues.

ParaFishControl


10 September 2019 - 16:00-18:30

While bacterial and viral diseases of cultured finfish have been extensively studied and have witnessed substantial advances in their control, parasitic diseases have received less attention and research funding. Nevertheless, disease prevention and management are essential for the sustainability of the European aquaculture industry. The diversity of species and farming practices throughout Europe involves a significant number of threats from numerous pathogens. These pathogens hamper production, and require specific preventive and curative practices and tools to ensure a high level of biosecurity in aquaculture production and related seafood products.

Over the last four years, the EU-funded project ParaFishControl (634429) has been working to develop innovative solutions and tools for the prevention, control and mitigation of the most harmful parasitic species affecting the main European farmed fish species, namely: Atlantic salmon, rainbow trout, turbot, gilthead seabream, European sea bass and common carp.

The “Mediterranean Fish Parasite Management Strategies” workshop will focus on the parasites which have been most damaging to Mediterranean farmed species populations - Amyloodinium ocellatum, Ceratothoa oestroides, Enteromyxum leei, Enteromyxum scophthalmi, Enterospora nucleophila, Philasterides dicentrarchi, and Sparicotyle chrysophrii. During the workshop, industry representatives will provide an overview of the most prevalent issues related to parasitic diseases in Mediterranean aquaculture farms. ParaFishControl partners will then present the new tools and techniques developed within the project to diagnose, prevent and treat these diseases. The workshop will provide attendees with new knowledge to better manage their farms, and greatly reduce population loss in a cost-effective way.

Trans-national study to define epidemiological cut-off values (ECOFF) for Vibrio and other aquatic bacteria

Antimicrobial resistance (AMR) is a major issue for both human and animal health, and tackling it requires a One Health approach. Aquaculture is rapidly growing internationally. Antimicrobials are widely used in aquaculture for therapeutic or prophylactic purposes and this usage is often not strictly regulated. There is a growing concern over good practices and other measures to support the prudent use of antimicrobials throughout the food chain. Knowledge of AMR in aquaculture is poor compared to other animal species. AMR in aquaculture may develop in fish and shellfish bacteria as a result of antimicrobial therapy or by contamination of the aquatic environment by human or animal waste containing antimicrobials and antibiotic resistant bacteria and AMR genes.

Vibriosis caused by various Vibrio species has a major worldwide economic impact in freshwater, brackish and marine fish and shellfish culture . Vibrio anguillarum, Vibrio vulnificus and Vibrio parahaemolyticus are all examples of as severe aquaculture pathogens. Data on AMR in Vibrio spp. from aquaculture are scarce and those are available are often not produced using internationally recocognised antimicrobial sensitivity testing guidelines and associated interpretative criteria.In particular there are, to date, no established epidemiological cut-off values (ECOFF or ECV) for any of these species. We have established a network of laboratories to help develop epidemiological cut off values using both disc diffussion and broth microdilution-based methods for V. anguillarum, V. parahaemolyticus and V. vulnificus spp. The aim of this roundtable is to present results to date and to discuss what further work needs to be done to enable the generatation of more data on a larger number of Vibrio and/or other bacterial species.

The roundtable will be opened by a presentation from Peter Smith on the theorical aspects of epidemiological cut off value determination.
