Does anyone know about Deep Sea aquatic life depreasurization or deep sea marine life to give me their opinion on what im thinking?

Hey everyone! I just wanted to make a post here and see if anyone knows more than me on this. Currently I'm starting as a freshman at Florida Institute of Technology in the fall and as a student there our senior year we need to present a project to the school fair in order to graduate. Usually undergrad students start planning for the project they are going to make in their freshman year and do research and other short projects in the mean time to learn the skills to make their final project. Im looking into producing a product to make it so we can bring aquatic life from deep in the ocean up to the surface for study or even zooculture. Ive only seen a few small projects like the subCAS thats gone down to 600 feet but only in certain places. I just wanted to get some feedback from people and see what they thought and if this would be a good undergrad project.

Fish are affected by the pressure change in a destructive way because of their swim bladders expanding. Crustaceans, echinoderms, jellies, etc that dont have swim bladders arent nearly as effected. Simply using a needle to pop the swim bladder is enough to release the pressure and keep the fish functional, the small needle wound doesnt permanently harm them. Ichtyologists like Richard Pyle use this technique widely to keep their specimens healthy as they ascend. No need for pressurized tanks or long decompression schedules. Even just a couple hundred feet is hundreds of psi, so a very small tank would be subject to thousands of pounds of pressure over its surface. You could build a system like this and have a small wet bomb thats a pain to maintain, or you can do a quick fish stabbing and put them in standard surface pressure tanks.

Look up some research first about fish that can move from deep pressure to the surface. Many species do a vertical migration at night to come up to feed or reproduce. I once saw a batfish in 2 feet of water! Could be a good starting point to help yourself understand more about physiology to survive different conditions.

Jeff Drazen did this when he was at MBARI, he’s now at University of Hawaii, so check his work out.
It’s hard, but not impossible to get animals to the surface under pressure. The real trick is keeping them alive when they get there. Because you need to clean the water, provide oxygen, all under pressure. And eventually feed the animals and remove solid waste.
Honestly, the numbers of animals you can get to the surface are so low, and the experiments you can do are so limited that it’s not worth the trouble. The technology to do work underwater is available to do these experiments on the seabed an that’s very hard but possible.

There was a PI at the university of Delaware in Lewes that had pressurized deep sea tanks bc he studied hydrothermal vents they have a pretty good program there.

Your school better have exceptional funding, maybe your family?
Otherwise you could write a proposal letter to Woods Hole & hope that they may be amenable to helping you with your project.
They're very cool people. Wish you the best of luck!
I wanted to be a marine biologist ever since I was a child but it just didn't work out that way.
Didn't get the proper schooling, doesn't mean that I don't have the proper knowledge😉🐋🦀

This seems very difficult for an undergrad project. You would need to maintain pressure (and low temperature) while providing food, oxygen and waste removal (and ample space) to keep the organism alive. If you can pull it off, then bravo!
