To my knowledge, anyone who does research on live Antarctic toothfish conducts their work in Antarctica and keeps the fish in tanks with water from the nearby frigid ocean environment. In my research, I used otoliths (fish ear bones) to estimate their age and growth and the majority of my work was conducted in laboratory. The otoliths were collected by fisheries observers who go out on fishing boats and collect biological data. I hope that answers your questions! Cassandra Hi Arpine,

It fascinates me that there is life in such freezing temperatures of waters. I was wondering if you could explain how you go about conducting research on these fish since they need the subfreezing temperature of water to survive? Do you have water set at a certain temperature to keep them alive while they are out of the ocean? Thank you so much I hope to hear from you soon! Best of luck, Arpine Bandaryan Hi Cassandra,

Sounds like you have a very interesting report you are doing and I will do my best to answer your questions. The antifreeze proteins found in Antarctic fish can be cloned in the lab, so in that sense, yes they can be replicated scientifically. I do not know if it could be placed in the human body for cold resistance, I think that would be a very complicated thing since we aren't in other ways adapted to freezing temperatures. However, people are currently doing research to see if they can use these proteins to prevent plants (crops) from freezing and for the potential preservation of tissues and organs. See the link I found on the NSF website for some good information (http://www.nsf.gov/pubs/1996/nstc96rp/sb3.htm). This report is from 1996, so they have likely more recent research you can look up for how fish antifreeze proteins are being used. If you do a quick google search on fish antifreeze proteins or uses for fish antifreeze proteins you should find some later stuff. Also, check out this PDF I found on the use of fish antifreeze proteins in ice cream (http://www.themilkweed.com/Feature_06_Dec_1.pdf)! And wikipedia also has a whole page on this topic (http://en.wikipedia.org/wiki/Antifreeze_protein). Good luck and enjoy and let me know if you need more help or have questions! Best of luck with your project! -Cassandra Hi Avi,

For an oceanography project in school i am doing a report on your exibition and would like to know: A) If the Protien found in the fish can be replicated scientifically in the lab? and B) if the protien can be placed and thrive in the human body for cold resistance? thank you for the help I read your blog about the Toothfish and found it very interesting.

I also enjoy reading what others are doing and how they live in Antarctica, including your story on the toilet tent! Hope you are enjoying the comforts of being back home. I wish you the best of luck in your work. Its amazing to me that we can be doing work in Antarctica from Santa Cruz… We should share pics and stories. Best wishes, Cassandra Dear Nadine,
