Fish joke for Monday-itis
What’s called a fish and is silver but isn’t a fish?
A silver fish!
Go figure.
Sea food at New Port, Rhode Island
After a day of whale watching, some of us escaped the cafeteria food to enjoy some local fresh seafood at Newport. It was an enjoyable meal shared with fellow students at Aquavet.
From left to right, Dr Rob Ossiboff (Cornell Pathology Resident), Ms Kelsey Shroeder, Ms Heidi Fink and Ms Deanna Sin (all part way through their veterinary studies).
Goldfish come in so many colours and flavours!
Logo for Aquavet 2012
Each year, the students at Aquavet put in a submission for a T-shirt logo so that we may have something to remember our experience by. Unfortunately mine didn’t make the cut 😦
But, it’s going to be made into mugs ;P
Check out how many different animals you can see in the logo I designed!
What are parasites? How can you visualise them better on microscopy?
Day 7, Dr Sarah Poynton from the John Hopkins Medical Institute, presents at Aquavet 2.
“Parasitos” = to eat at another’s table.
Parasites are organisms that they are nutritionally dependent on their host.
They’re not always primary pathogens.
Did you know that Microsporidia are now considered to be more closely related to fungi?
And that Myxosporea are now considered to be more closely related to metazoa?
Some of these bugs are difficult to visualise under normal HE stained histological sections. So what are some useful histological stains that can be used to help with visualising the very small parasites?
- Gram
- ZN
- Giemsa
- PAS
- Protargol (similar to GMS, a silver stain)
- DAPI
- Feulgen
Other techniques include
- Normarski (differential interference contrast).
- Wet preparations (to visualise movement)

The nautilus has up to 90!
Why study fish?
Apart from the reason that they’re so interesting, there are countless reasons. The material below is a summary taken from Dr Jeff Wolf’s presentations over the last two days at the Aquavet II course.
We study fish for the:
Improvement of aquatic animal health
-Sport and commercial fisheries
-Aquaculture, ornamental fish trade
Animal models of human diseases
-Naturally occurring or genetically created
-Less emphasis lately
Surrogate test species for toxicology
-Less expensive than some mammalian models
-Less resistance from animal welfare advocates
Environmental sentinels
-Carcinogenesis
-Endocrine disruption
But why study fish of all things? Why not study birds?
It’s because the aquatic the aquatic environment is the essentially the “sink” for everything from the human household, to the industry, to farming, everything ends up in the water. Fish act as sentinels for our environmental health and our health.
The picture below is from a lecture provided by Jeffrey C. Wolf, DVM, DACVP from the Experimental Pathology Laboratories (EPL®), Inc. Sterling, VA, USA. He sourced this picture from Mr Ed Orlando.
We need to start thinking of the “One Health Concept” rather than thinking about it as animal health, fish health, human health, environment health. We live in a very interconnected world where for every action, there is a consequence.
