The AAHP now has a Facebook page and Twitter feed!!!

Here’s the link to the new Aquatic Animal Health Program Facebook page.  I also have a Twitter feed. Our first use will be to post periodic updates and location indicators for the Rio Negro expedition which begins next Saturday. There will be a message and a link to the Delorme website. When you click on the link you will see a map with an arrow indicating our location. I’m using an inReach satellite communicator which only allows text messages and location information.

We’ll try to post some pictures when we get wireless access, probably only 1-2x during the course of the trip. One of my colleagues may be live blogging. If that works out, he will be using a sat phone and a data package, I’ll send the weblink.

In the future I’ll post bits of news, upcoming educational opportunities, and program activities.

Chat soon.

Heading off for our Annual Study Tour to Japan

We are heading to Japan Monday morning for our annual trip. Looking forward to meeting old friends and making new ones. I’ve included the outline for the formal portion of the trip . Some may find it interesting. We will also be visiting the Takashi Amano Gallery as well as the Ring of Fire Aquarium in Osaka as well as the Suda Aquarium in Kobe. We’ll have the opportunity to tour behind-the-scenes and meet withe directors, curators , veterinary and husbandry staff. We’ll probably also visit the Hiroshima Memorial as well as the temple complex in Narita.

STUDY TRIP: JAPAN 2012
HEALTH MANAGEMENT WITHIN JAPANESE KOI INDUSTRY
&
DEVELOPING ADEQUATE HEALTH MANAGEMENT PROGRAMS FOR JAPANESE KOI IMPORTED INTO THE UNITED STATES

NOVEMBER 12-21, 2012
Total CE credits proposed: 22 CE Credits

Lead Instructor: Tim Miller-Morgan, DVM
Extension Veterinarian – Aquatic Species
Lead, Aquatic Animal Health Program
Oregon Sea Grant and OSU College of Veterinary Medicine
Oregon State University

Co-Instructors:
Mr. Tony Prew, All Japan Koi, Hillsboro, OR, USA
Mr. Hoshino Masaharu, Koda Yorijo, Niigata, Japan

GOALS: The primary goal of this trip is to familiarize U.S. veterinarians with the Japanese koi industry and the health management practices within the Japanese koi Industry. Further, we will discuss opportunities and barriers to developing health management programs for imported Japanese koi with U.S. based importers and some the characteristics of the high-end U.S. koi hobbyist and their motivations for participating in the hobby and their information seeking strategies. Finally, we will participate in a group project to develop the concept and basic plans for a non-profit fish hospital.

Program Sessions:
1. Farm Visits – Niigata, Chiba and Hiroshima. We will visit a number of small family farms in the Niigata region of Japan and two large farms located just outside of Hiroshima and another outside of Chiba. (15 hours)
a. Farms in Niigata: Shinoda Yorijo, Yagozen, Marusaka Yorijo, Koda Yorijjo, Hosokai Yorijo, Suda Yogyojo. Farm in Hiroshima: Konishi Koi Farm. Farm in Chiba: Tani Farms
b. Instructors: Dr. Tim Miller-Morgan, Mr. Tony Prew and Mr. Hoshino Masaharu
c. Expected outcomes:

  • Observe standard koi handling practices
  • Observe and discuss basic biosecurity protocols related to pathogen exclusion and pathogen containment on and between farms.
  • Discuss common diagnostic procedures and infrastructure available to the koi farmers.
  • Discuss common treatment methodologies utilized by koi farmers in Japan.

2. ZNA 48th International Koi Show, Kobe, Japan – We will attend this koi show and spend time observing some of the highest quality show koi in the world. Mr. Prew a recognized expert on koi varieties and quality will lead this session. (2 hours)
a. Instructors: Mr. Tony Prew and Dr. Tim Miller-Morgan, DVM
b. Expected outcomes:

  • Review the common varieties of koi
  • Discuss assessment of koi quality including: body conformation, color, pattern, deportment and defects.
  •  Observe the common biosecurity protocols utilized at Japanese koi shows.

3. Principles of biosecurity for the koi industry (1 hour)
a. Instructor: Dr. Tim Miller-Morgan
b. Description: Biosecurity consists of the practices and procedures used to prevent the introduction, emergence, spread, and persistence of infectious agents and disease within and around fish production and holding facilities. Furthermore, these practices help eliminate conditions that can enhance disease susceptibility among the fish. In short, biosecurity precautions are put in place to exclude and contain fish pathogens. Biosecurity practices are applicable to all levels of the koi industry: producers, importers, retailers, and hobbyists. Proper use of biosecurity measures will help prevent introduction of infectious disease in a fish facility, and will also help minimize the risk of diseases being passed from producer to hobbyist. Such practices will lead to a healthier and more sustainable industry since decreased or reduced disease leads to decreased losses among broodstock and grow out fish lots, decreased financial output to treat or manage disease outbreaks and improved overall quality of fish for the export or the domestic market.

As import-export regulations for koi become increasingly stringent on a global level, veterinarians may be called upon to assist koi facilities in the planning and implementation of biosecurity programs. We will present a brief overview of the major considerations that should be taken into account when developing a biosecurity program for a koi facility.

Basic biosecurity procedures are uniform across the industry, but the biosecurity plan will be tailored to meet the special needs of each business. As the scope, needs, and finances of the business change, the facility manager will modify and adjust biosecurity measures accordingly, yet maintain the basic tenets of good biosecurity practices.

Designing and implementing biosecurity practices can be simplified if we consider some basic themes: pathogen exclusion, pathogen containment, and basic best health practices. We will consider the elements of each, and show how these elements will allow you to hinder access of pathogens to a facility, control the spread of pathogens that may emerge, and promote high health and disease resistance among the fish in the facility. The overlap of practices addressing these themes will become evident.

4. Development of Best Health Practices for the U.S. Based Koi Dealer and Importer. Opportunities and Barriers for the veterinary practitioner.
(1 hour)
a. Instructor: Dr. Tim Miller-Morgan
b. Description: This Best Health Practices Program (BHPP) is a new initiative aimed at helping control the spread of disease within ornamental pond fish retail facilities and to their customers. Project KHV provided initial support for this project, it is a charitable committee formed in 2004 by the Associated Koi Clubs of America, a nation-wide umbrella group of over 100 Koi clubs. The initial goal of this project was to focus on controlling the spread of Koi herpes virus (KHV) within the US. However, it became readily apparent that a true best health practices program should be broader in scope and address the risks associated with a wide range of common infectious diseases of ornamental pond fish.

The need for such a best health practices program was validated through a national survey of ornamental pond fish retailers and veterinary practitioners actively involved in pet fish medicine.

The BHPP has been designed and written by a group of aquatic animal health professionals. The BHPP is anticipated to operate as follows: Ornamental pond fish retailers will have access to the BHPP implementation guidelines through web-based or face-to-face workshops. Interested retailers may opt to participate in this voluntary program. Trained veterinary practitioners will be able to contract with these retailers to help implement the BHPP and assist with ongoing quality control, quality assurance, health monitoring and disease surveillance. In the future it is possible that compliant retailers may be issued an annual certificate by their veterinarian indicating program compliance. The veterinarian will continue to verify the dealership’s adherence to the program by requiring written Standard Operating Procedures that include ongoing reporting and disease surveillance:

• Facility configuration,
• Biosecurity,
• Employee training,
• Record keeping,
• Regular dealer reports on quarantine,
• Immediate reporting of suspected diseases of concern,
• Appropriate corrective action as required, plus
• Periodic site inspections.

Participating dealers would agree to quarantine all incoming Koi for a specific period of time and at a specific temperature necessary for a number of common diseases to be revealed. Further, they agree to health screening of fish in each fish lot arriving at the quarantine facility. If screening procedures indicate no evidence of disease or asymptomatic carriers, the fish are released for sale. If disease is suspected, the partnered veterinarian directs and monitors the dealer’s investigation and corrective action.

An online course and accompanying wet lab will also be available to those interested in becoming certified BHPP veterinarians. One of the other goals of this program is to build further opportunities for veterinarians within the ornamental fish hobby and industry.

For Hobbyists, the advantages are obvious. Customers would have a reduced risk of purchasing diseased fish from retail facilities.

For Dealers, the advantages include:

• The BHP helps prevent disease from entering other portions of their facilities beyond quarantine,
• Being proactive and adopting reasonable self-regulation may preclude or at least forestall mandatory government intervention into this problem,
• It offers an opportunity to establish a working relationship with qualified veterinarians who can provide additional valuable fish-health advice and services, and
• Dealers can favorably differentiate themselves in the marketplace.

It is important to note that the BHPP does not certify any fish as being disease free. It is a best management program designed to minimize the likelihood of an infected fish leaving a dealer’s facility.

The authors group developed the preliminary BHPP and an associated online training program for veterinarians. Six koi dealers from across the US and four veterinarians participated in this beta-test of the program to assess the feasibility, practicality and effectiveness of the overall program. Feedback was provided throughout the implementation process and after the participating veterinarians had determined each facility had achieved compliance.

We will discuss the outcomes of this beta-test as well as some of the opportunities for practicing veterinarians and pitfalls that can be associated with developing health management programs for this sector of the industry in the United States.

5. Characterizing the Koi Kichi – What makes the koi hobbyists tick, How do we reach them?, and How to we get compliance? (1 hour)
a. Instructor: Dr. Tim Miller-Morgan
b. Description: Hobby activities can be viewed through the lens of informal, free-choice learning. A wide range of hobbies combine fun and learning-intensive practices, and can contribute to scientific literacy. Hobby learning involves clear goal orientation, persistence and effort, and often results in more richly and strongly connected knowledge; traits highly valued in both in and out-of-school science learning. In this study, Koi hobbyists were sued as subjects to discover and explore hobbyists’ information-seeking strategies under different learning scenarios. We approached koi hobbyists’ learning about koi and their koi hobby in both quantitative and qualitative ways. We designed a Stage of Engagement Model to illustrate koi hobbyists’ engagement with their hobby, and adapted Falk and Dierking’s Contextual Model of Learning to explain how personal, socio-cultural and physical contextual factors affect koi hobbyists’ learning.

An instrument was developed to assess koi hobbyists’ experience with keeping koi, knowledge about the hobby, motivation/goals, interaction with other hobbyists, and the information-seeking strategies they used under different learning scenarios. This questionnaire was administered to koi hobbyist communities in the U.S. Pacific Northwest and online. Based on the quantitative analysis, the results supported the hypotheses that koi hobbyists chose different information-seeking strategies based on personal contextual factors such as previous experience, motivation and learning goals; socio-cultural contextual factors such as interactions with other koi hobbyists; and physical contextual factors such as the nature of the problems they encounter. Koi hobbyists also chose different information-seeking strategies based upon their stage of engagement with their hobby. The long-term potential of this study is to offer insights into how learners construct their knowledge by applying different learning strategies under different personal, socio-cultural and physical circumstances, and to provide a framework for the future study of other kinds of hobbies and hobbyists that will help to promote public scientific literacy.

The results of this work will be useful for the veterinary practitioner wishing to develop better communication with this unique client base. This work provides some valuable insights that are very useful in terms of understanding changing needs and information sources of the koi hobbyists as he/she moves through the hobby.

This work based upon the PhD Dissertation of Dr. Michael Liu, a former Senior Aquarist and Research Aquarist within the Aquatic Animal Health Program. He received his PhD in Science and Math Education/Free-Choice Learning.

6. Designing the Optimal Fish Hospital (roundtable discussion) (2 hours)
a. Instructor/Facilitators: Dr. Tim Miller-Morgan and Tony Prew
b. Description: Participants will discuss the key aspects and features necessary to develop a not-for-profit fish hospital serving both freshwater and saltwater clients. The final outcome of this roundtable will be a rough diagram of the facility as well as a basic equipment and services synopsis.
c. Expected outcomes:

  • Develop a list of basic services that could be offered at such a facility
  • Develop a strategy for staffing such a facility: Medical director, technicians, local clinicians
  • Rough floor plan for such a facility given the current footprint available and the existing structures (the land and some basic structures are in place.
  • Develop a basic equipment list for equipping such a facility.
  • Assess interest for further participation in this project and develop a communication strategy.

 

I will try to post a few comments and pictures as we progress on our trip.

 

Until later.

2012 Ornamental Fish Medicine Course, Hatfield Marine Science Center, Newport, Oregon

 

Just finished teaching 1 week intensive Ornamental Fish Medicine Course. Great group of 12 participants: 8 senior veterinary students from OSU, 2 professional aquarists (Oregon Coast Aquarium and Seattle Aquarium), 1 veterinarian from the SEattle Aquarium, and 1 colleague from India ( Dr. Anna Mercy, Kerala College of Fisheries and Ocean Sciences). Great learning experience for all of us. Great exchanges during the lectures, labs, group projects and case studies. Looking forward to next year. Considering expanding to 2 weeks. Thanks to my co-instructors: Dennis Glaze, Dr. Jerry Heidel, Stu Clausen, and Dr. Anna Mercy.

 

Dr. Mercy is from Kerala College of Fisheries and Ocean Sciences, India. She participated in the course but was also kind enough to give two lectures. One lecture addressed the current status of the Indian ornamental fish industry and outreach work she has lead to train ornamental fish farmers. In the second lecture Dr. Mercy discussed some of the common health problems associated with collecting native broodstock  and breeding these fish in captivity. We recorded both of these lectures and you will be able to view them on our YouTube channel soon. I will post the links once the lectures have been posted.

 

Here’s the course outline for the course this year.

Industry Profile: Aquatic Animal Veterinarian

THE PET FISH DOCTOR

March 2011

When your dog or cat needs medical care, it’s generally not difficult to find a local veterinarian who is familiar with the general afflictions facing these species. But if your fish needs a doctor, whom are you going to call? Veterinarians with knowledge of pet fish medicine may be few and far between, but they do exist.

Dr. Helen Roberts is a small and exotic animal veterinarian who is one of the few practitioners in the country who provide medical and surgical care for fish. Located only 15 minutes from Niagara Falls, she is a partner at the 5 Corners Animal Hospital and is the go-to fish doctor at her associated practice, Aquatic Veterinary Medicine of Western New York.  She says that when she talks to people about her work, most are “amazed” that she treats fish, and that she even performs surgery on fish. “I think the public perception is once a fish is sick, it’s dead,” she says. But through her veterinary practice, her educational publications and her lectures to all kinds of audiences about fish health, this outdated perception is beginning to change.

Dr. Tim rambling on about various aspects of Koi Health on KoiTV

Koi-TV features videos of Dr. Tim demonstrating and discussing various common fish health procedures and protocols on koi. These were all done in one take. To my colleagues who will say, ” you should have mentioned…..”, yes I know. I will address some these in later posts. It’s hard to remember everything without cue cards.

My profound thanks to Promod and Sumi from KoiTV for their patience on this project. I hope we can continue and produce some more educational vignettes.

Dr. Craig Adams, MS, DVM discusses fish surgery

From AVMA, AquaVetMed an interview with one of our local, Pacific Northwest Fish Veterinarians: 

 

As the field of aquatic veterinary medicine expands, so do the medical options available for fish. One of these options is surgery.

 

As fish become more popular as pets, the demand for veterinarians to look after their health also increases. Whether you’ve got a guppie or a koi, any fish owner who develops a strong bond with their fish wants access to the best health care they can find. As the field of aquatic veterinary medicine expands, so do the medical options available for sick or injured fish. One of these options, explains Dr. Craig Adams, a mixed-animal veterinarian and owner of Aquatic Veterinary Services in western Washington, is surgery.
