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.

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.

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.

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.

NEWS AND LINKS: November 19, 2010

  • Report reveals gaps in federal regulation of imported animals
    A Government Accountability Office report released Monday said it found lapses in the way federal agencies regulate foreign animals imported to the U.S., which totaled at least 1 billion between 2005 and 2008. The influx of foreign animals can lead to the emergence of zoonotic diseases that can spread around the world, the report stated. (Very Interesting reading, I’ll have a few comments soon. Some may be surprised at the number of fish imports. TMM)
  • From Ornamental Fish International a very brief report from Keith Davenport or the Ornamental Aquatics Trade Association on the recent Conference of the Parties to the Convention of Biological Diversity held in Nagoya, Japan, October 18-29, 2010.

CBD CONFERENCE IN JAPAN (Links to draft decisions and background information are included, TMM)

Keith Davenport (OATA) and also on behalf of OFI, EPO, PIJAC and PIJAC Canada, attended the CBD meeting from 18-29 October in Nagoya, Japan. Some 18.000 participants from 193 countries participated.

Keith reports:

“A number of issues covered are directly relevant to the industry immediately or in the future. The invasive species issue first became prominent in the CBD in the mid nineties and that issue has blossomed not only because it is serious, but scientists, and to a lesser extent officials have made a career out of the subject. Among the topics of note were:

Invasive alien species, in particular aquarium, terrarium, live food and bait species (Draft decision).

The meeting discussed the issue and agreed to establish an ad hoc Technical Expert Working Group (AHTEG) on the subject, which Spain has agreed to fund. So it will meet and discuss invasive pathways and risks trade in aquarium, terrarium, live food and bait species. Industry is to be included but to reinforce the point I made an intervention.

It remains to be seen how the industry gets invited to participate.

PIJAC are still developing a “tool kit” which might be launched at an AHTEG. Diseases are considered invasive species.

Strategic Plan Draft decision

This was hotly disputed and only agreed on the last day. It establishes targets for various matters surrounding biodiversity to be met by 2020. They follow on from a 2010 set of targets, which they failed to meet. The targets cover a wide range of items including public awareness, invasive species, sustainable use, poverty alleviation etc.

We could ignore them. However, we could also start to compile examples of what we do as an industry which, even if sometimes unintentionally, help to support meeting the targets. If we, the global industry, started to compile examples, we could produce literature, a web site or even hold side events at the next appropriate CBD meeting. For reasons that I explain more fully below the CBD is in a “we love business” mode at the moment and there is less risk now than perhaps ever that this would back fire. I have in a sense already put a mark in the sand with the item I wrote for the CBD Business 2010 magazine. The benefits may be a generally more positive view being taken of the industry globally. While we can work to influence issues in our home countries and the EU a quite closely, this may help color opinion about our industry more positively throughout the countries that are in our supply chains.

The Economics of Environment and BiodiversityTEEB

TEEB has in some senses taken the world by storm. Massive side events, political endorsement from all directions, endorsements from the World Business Council for Sustainable Development, mention in almost every decision made were just some of the accolades. Major companies were queuing up to say they had supported TEEB or were starting to or had undertaken TEEB projects within their business.

TEEB looks at the value of “environmental services” such as rainfall, river flow, carbon fixation by forests and the like. An example that keeps being mentioned is the use of forests, especially of those on sloping ground, in China. The value of the wood extracted was a fraction of the costs paid in losses due to landslides, floods and the like. China now no longer logs its own forests so heavily but buys in wood from Madagascar. The environmental costs of the logging in China (and now in Madagascar) were externalized by users. TEEB emphasizes that the price of environmental services used or conserved should be internalized in business accounts and pricing.

Large companies are looking to benefit by being allowed to put on their books the value of the environmental services on land they own and haven’t used or have restored. There was repeatedly talk of a market in the mold of the carbon market for environmental services.

Our industry helps play a part in conserving rainforests and reefs. In the Barcelos region of Amazonas where 70% of the income derives from ornamental fish collection there is, I believe, 8 billion tons of carbon fixed. The price for carbon is approximately €13 per ton. So we might suggest our industry plays a role in help keeping €100 billion worth of carbon fixed. We will never get a cent from it, but it puts in context an unintentional consequence of our activities. Equally on the reef arguments along these lines might become apparent if we were delve a little.

Access and Benefit Sharing (ABS) from genetic resources – Draft decision

I kept a watch on this issue and did talk to UK and EU officials about this briefly. They remember past positions I had presented and so it did not take much of my time. Anyway, after 10 years of negotiations officials broke up at 1 am in the morning of the final day with no agreement. The President of the meeting (a Japanese Minister with help from CBD legal staff) cut out all text that could not be agreed on. The actual text was agreed at 3am on Saturday after a 3 hour boozy reception hosted by India to celebrate being awarded the next COP in 2012. I think the main protagonists were worn out and under political instruction from the 100+ Ministers present.

Amongst the text that was removed was some saying commodities (which the EU said included ornamentals) would not be included. This reference was removed and so the picture is less clear. Indeed, the failure to get agreement on many areas just leaves uncertainty.

At worst breeders may be required to obtain Prior Informed Consent (PIC) and establish Mutually Agreed Terms (MAT) before accessing genetic materials (breeding stock). However this unclear. It is also not clear if the agreement applies from next year on when it is likely to formally start its work of 1994 when the Convention (with its text on this issue) came into force.

I think that countries that were aggressively pursuing the harshest conditions on access and retroactivity may implement “harsher domestic measures”. There might be an obligation on the governments of importing countries to help resolve disputes. All the Africa and South America as well as Malaysia and India could prove difficult on this issue if they move their gaze further than pharmaceutical products. Will we have more cases of “biopiracy” as highlighted in Brazil for instance?

Industry engagementWeb link

There were more industry representatives than I have ever seen before. The CBD Chief Executive made an impassioned statement along the lines that “industry may not just be part of the solution to biodiversity loss it may be the solution”. I think this was echoed in part by others. Though mainly they are anticipating funds they do seem prepared to recognize positive impacts of industries. Several delegates especially one from Sweden said after a discussion the pet industry might be better served by being more vocal.

CBD Conclusion

There was a wide range of other discussions on relevant issues. As I said above we can ignore them. However, I have found following the invasive issue in from the CBD to the UK and the EU has helped in promoting our case and in some cases turning the tables on officials to achieve outcomes more to our benefit. I think maintaining a presence at the meeting so a face from the industry that becomes “part of the furniture” is useful.” ( As we often say here in Oregon when policy/regulatory issues arise, ” You’re either at the table or your on the menu!” – TMM)
