A tragic loss for the ornamental fish industry.

Last Thursday many of us lost a great friend and the ornamental fish industry lost a tireless advocate. OFI Secretary-General, Alex Ploeg, his wife, Edith, and their son, Robert, were on the Malaysian Airlines flight 17 shot down over the Ukraine. A truly senseless tragedy.

Practical Fish Keeping just published a short article about this tragedy and the impact Alex has had on the industry during his tenure as OFI Secretary-General.

You may also go to the OFI website to read some personal messages from fiends in the global ornamental fish community.

Our thoughts and prayers  are with their two daughters , Mirjam and Sandra, who must now move ahead without their parents and brother.

Viral disease in Ornamental Fish

Since we are on the topic of viral diseases, I thought I’d share a few recent publications about viral diseases in ornamental fish and a few associated with food fish. These are excellent  publications that are not too technical but provide a nice overview of the current state of our knowledge regarding the biology and management of these diseases.

Below are two background publications about the basics of fish viral diseases and the potential role of vaccination as part of an overall biosecurity program.

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.

Under the Sea Radio – Another Interview

I’m a bit late posting this but on February 5th I did another interview with the Under the Sea Radio Show. We had a wide ranging discussion over two hours. THe first hour really addressed careers in veterinary medicine with a focus on aquatics. The second hour was quite an open discussion of fish health management. I hope you enjoy the show.

So what does Dr. Tim do at the Hatfield Marine Science Center? The lost radio show found!!

It has been quite awhile since I’ve posted. Here is a little interview from the past.

Marine Science Chat is a regular radio show in Newport that showcases individuals and work being done at the Hatfield Marine Science Center. These shows are also available as podcasts.

I  participated in one of these programs a number of months ago but the  file was lost foe a time. The interview is now available. So if you are interested in what I do at the HMSC have a listen.

I’m heading to Japan later today. Stay tuned for posts about this current trip.

Dr. Tim discusses quarantine of marine ornamental fish and invertebrates

Last week while I was in Singapore I had the opportunity to discuss fish health management and particularly quarantine of marine ornamental fish and invertebrates with Kevin Erickson a director-at-large with the Marine Aquarium Society of North America.

I’m constantly amazed at technology and the capability to communicate globally. We did the interview via Skype. Kevin was in Stirling, Scotland and I was in Singapore. What an amazing world!!

I hope you find the interview interesting. Please feel free to post any comments. I’m always interested in your comments and opinions.

Farm Visits – Singapore and Malaysia, some impressions

On my way home today.  I’m writing this at the airport in Vancouver BC.

Over the past few days I’ve had the opportunity to visit a number of farms and export facilities in both Singapore and Malaysia. What I’ve taken away is an industry in these countries that is working to significantly upgrade their biosecurity and health screening procedures to meet increasing demands as well as anticipated new requirements from the World Animal Health Organization, the EU, Australia and to some extent the US.

We visited a number of facilities with significant biosecurity protocols which included:

  • Separate quarantine facilities for export – fish are quarantined in these export facility prior to shipment. These facilities are separate from the actual production facilities. We visited two of these facilities that are slated to come on line in the next few months.
  • Some facilities have two levels of quarantine; pre-quarantine at the production facility prior to shipment to the export quarantine facility.
  • Separate facilities for holding domestic and imported fish.
  • Movement from pond culture to tank and cement pond culture. Easier to prevent disease spread and easier to disinfect the rearing units.
  • Tanks and ponds with individual water supplies and filtration. Water is not shared between tanks/ponds.
  • Dedicated equipement for each tank or rearing unit.
  • Individual siphons for each holding/rearing tank. These were actually hard-plumbed. Pretty cool idea.
  • Bird netting, covered or enclosed rearing areas.
  • Regular disease screening for export purposes but also as part of an ongoing health management program.

These are a few of the more significant examples of the move to more biosecure production systems.

Of course, there are still many facilities that are rearing fish in the older style pond culture systems many with many cage nets within individual ponds. There are also problems with pest control in some facilities – frogs moving between pods, birds, snakes. Further, there are instances where there appears to be inadequate disinfection between batches, not pulling mortalities quickly and inadequate equipment disinfection. I believe all of these issues can be addressed in time.

However, the hobbyist must be willing to pay more for this increased level of health management and biosecurity. All too often I hear, particularly in the US that hobbyists want healthier and safer fish but I’m told by many retailers that they are unwilling to pay more for these fish. Price still seems to be the guiding factor. THese additional health management practices add cost to the production process and it is important for the hobbyist to understand this fact.

Just some initial thoughts. Next I will post some images to give you a feel for the different types of farms and export facilities. Stay tuned. TMM

Aquarama – One of the Premier Ornamental Fish Industry Trade Shows. Some thoughts and Observations.

I’m in Singapore, a wonderful city, attending Aquarama one of the major ornamental fish trade shows.

A panoramic view of Marine Bay, central Singapore

Aquarama is an annual trade show held at the Suntec Convention and trade center in Singapore. The show provides an opportunity for may segments of the industry to come together and network, see new products, conduct business, attend seminars and tour facilities.

The Trade Show

Dr. Tim Chatting with Scott Dowd from the New England Aquarium outside the Ornamental Fish International booth.

Water Bats!!!

It is a large event strictly devoted to ornamental fish and invertebrates. The show is also well known for its fish and aquarium show. Here producers enter fish, planted tanks and marine aquarium displays. THey are judged by experts and the winners announced. It is another great way for producers to showcase their products.

The Fish Show

Eric very excited about a red arowana

and the Bettas!!

THere are also two days of educational seminars, addressing key issues in the industry. Topics covered over the past two days focused on international perspectives on a changing industry and maintaining of improving quality of the animals traded. Speakers from multiple countries provided a diverse range of views, experiences and opinions. Specific topics included:

  • Resident-based Ornamental Fisheries in the Western Ghats, India: Managing Poverty Alleviation and Change at the community Level. – Dr. Rajeev Raghavan
  • An update on Recent Biosecurity Changes and Their Impact on the Australian Ornamental fish Sector – Shane Willis, Australia
  • Roadmap towards a “Green” Aquarium Industry – Scott Dowd, USA
  • Eco-Freindly Marine Culture and Capture – A Mexican Perspective – Dr. Nuno Simoes, Mexico
  • Potential Impacts of Climate Change on the Ornamental Fish Industry – Ryan Donnelly, Australia
  • A New quality Assurance Scheme to Assure better Quality  Ornamental Fish from Singapore – Poh Yew Kwang, Singapore
  • Total Quality Management in the Aquarium Business – Dr. Anton Lamboj, Austria
  • Fish Health and Biosecurity Issues in Retail Shops and Wholesale facilities – Dr. Gerald Bassaleer, The Netherlands
  • DNA Multi-Scan a New Fish Disease Diagnostic Tool – Dr. Kris Willems, Belgium
  • Implications of Epizootic Ulcerative Syndrome Legislation for the Ornamental Aquatic Industry – Somkiat Kanchanakhan, Thailand
  • EU Fish Health Legislation: Clarifying the Confusion and Introduction of New Online Tool for the Successful Completion of Health Certificates for Import – Alex Ploeg, The Netherlands
  • Invasive Ornamental Fish Species in Singapore: A Case Study – Dr. Ng Heok Hee, Singapore
  • A Trade Perspective on Invasive Species – Sven Fossa, Norway
  • A Profile of the Indian Ornamental Fish Industry with Special Focus on the Concerns of Key Players – Dr. Mini Sakharan, India
  • Trends in Breeding Marine Aquarium Fish: Where Are We Today and Where Do We Need to Go? – Matthew Wittenrich, USA
  • Where do Science, Industry, and Aquariums meet?Practical Applications for What Can Be From THings Learned in the Aquarium Hobby – Julian Sprung, USA

What I have taken away from these presentations and my discussions with industry members is that there are three emerging areas that all sectors of the industry must address in the next few years:

  • The need for improved biosecurity throughout all sectors of the industry. THis is being driven by new emerging diseases as well as re-emerging diseases that not only pose a threat to the ornamental fish trade but also to the  aquaculture industry for food fish and invertebrates. Consequently there is increased scrutiny by the regulatory bodies for national and international trade. THis is a truly global issue since ornamental fish are being exported from over 130 different countries.
  • The need to address the issue of aquatic invasive species. There are many animals traded that could have significant invasive potential in many countries. Many of these are banned for import but are often included due to poor quality control at packing or a lack of awareness of the specific regulations and/or risks on the part of the exporters and importers. There is a need for more research characterizing the specific invasive pathways as well as improved outreach and education at all levels when it comes to aquatic invasive species.
  • There is emerging pressure to develop specific guidelines that ensure adequate concern for animal welfare throughout all sectors of the industry. At this point the European Union and Australia appear to be the primary drivers though there are also emerging discussions on this topic in the United Staes as well. It is not inconceivable to envision specific regulations that would require documentation of  adherence to specific welfare guidelines in order for ornamental fish to be exported to some of these countries. This would probably be very much like a health certificate. Obviously, this will be an area of much spirited debate and diplomacy since the definitions of welfare, the perceptions of an actual need for guidelines, and the appropriate methods for guideline development and enforcement vary dramatically across the globe.

These are all weighty issues that will not be addressed overnight. However, it is very important to continue discussions, continue to develop industry solutions and to maintain contact and educate key regulatory bodies about the industry. The key is to remain proactive. The alternative is regulatory requirements developed and implemented with little industry input. Not making a decision to address an issue is a decision but it may not be a very good one in this case.
