New video reveals how aquarists care for animals at HMSC Visitor Center

Posted by: | May 10, 2017 Comments Off on New video reveals how aquarists care for animals at HMSC Visitor Center |

Have you ever wondered how aquarists care for the animals at the Hatfield Marine Science Center Visitor Center? Now you can learn all about it, by watching this fascinating, award-winning video from Oregon Sea Grant: Animal Care at the Hatfield Marine Science Center’s Visitor Center.

The full video (15:45) comprises six discrete segments, starting with a behind-the-scenes tour of the area where new and sick animals are quarantined and treated (0:52). Other segments explain how aquarists feed the animals (3:54), take care of the octopus on display (7:10), care for coral (9:27), propagate coral (11:39) and clean the tanks (13:16).

If you’d prefer to watch one or more individual segments rather than the entire video, you may do so by clicking on the appropriate link(s) below:

Oregon Sea Grant operates the Visitor Center, which features interactive exhibits and attracts more than 150,000 visitors each year. It is home to Oregon Sea Grant’s marine education program for K-12 students and teachers.

The video was filmed and edited by Oregon Sea Grant videographer Vanessa Cholewczynski.

Aquarium fish develop antibiotic resistance

Posted by: | January 17, 2013 Comments Off on Aquarium fish develop antibiotic resistance |

Discus fishNEWPORT, Ore. – The $15 billion ornamental fish industry faces a global problem with antibiotic resistance, a new study concludes, raising concern that treatments for fish diseases may not work when needed – and creating yet another mechanism for exposing humans to antibiotic-resistant bacteria.

The risk to humans is probably minor unless they frequently work with fish or have compromised immune systems, the authors said, but transmission of disease from tropical fish has been shown to occur. More serious is the risk to the ornamental fish industry,  a $900 million annual business in the United States.

There are few regulations in the U.S. or elsewhere about treating ornamental fish with antibiotics, experts say. Antibiotics are used routinely, such as when fish are facing stress due to transport, whether or not they have shown any sign of disease.

“We expected to find some antibiotic resistance, but it was surprising to find such high levels, including resistance in some cases where the antibiotic is rarely used,” said study Tim Miller-Morgan, Oregon Sea Grant’s Extension aquatic species veterinarian and an assistant professor with OSU’s College of Veterinary Medicine.   “We appear to already have set ourselves up for some pretty serious problems within the industry.”

In the new study, 32 freshwater fish of various species were tested for resistance to nine different antibiotics, and some resistance was found to every antibiotic. The highest level of resistance, 77 percent, was found with the common antibiotic tetracycline. The fish were tested in Portland, Ore., after being transported from Colombia, Singapore and Florida.

Findings of the study were reported in the Journal of Fish Diseases.

The bacterial infections found in the fish included Aeromonas, Pseudomonas, Staphylococcus and others, several of which can infect people as well as fish.

Problems and concerns with antibiotic resistance have been growing for years, Miller-Morgan said. The nature of the resistance can range widely, causing an antibiotic to lose some, or all of its effectiveness.

There have been documented cases of disease transmission from fish to humans, he said, but it’s not common. It would be a particular concern for anyone with a weak or compromised immune system, he pointed out, and people with such health issues should discuss tropical fish management with their physicians. Workers who constantly handle tropical fish may also face a higher level of risk.

From an industry perspective, losses of fish to bacterial disease may become increasingly severe, he said, because antibiotics will lose their effectiveness.

Anyone handling tropical fish can use some basic precautions that should help, Miller-Morgan said. Consumers should buy only healthy fish; avoid cleaning tanks with open cuts or sores on their hands; use gloves; immediately remove sick fish from tanks; consider quarantining all new fish in a separate tank for 30 days; wash hands after working with fish; and never use antibiotics in a fish tank unless actually treating a known fish disease caused by bacteria.

Sea Grant Veterinarian Helps Control Virus in Koi Ponds

Posted by: | January 28, 2009 Comments Off on Sea Grant Veterinarian Helps Control Virus in Koi Ponds |

Koi in a pondCORVALLIS, Ore. – Call him the koi doctor. An ichthyologist a la koi. The koi keeper’s confidant.

His patients are living works of art – brilliantly painted Picassos that swim in elaborate ponds and fetch up to $70,000 a piece. When disease strikes, the fallout can be disastrous, costing koi keepers in Oregon and around the world hundreds of thousands of dollars.

One half of a two-man SWAT team called in to render medical support for ornamental fish, Oregon State University’s Tim Miller-Morgan is a Sea Grant Extension veterinarian for aquatic pets, based at the Hatfield Marine Science Center in Newport, Ore.
