Question: what is a phd in fish feeding? do you just feed fish?

Lol, it was a little more complicated than that. So a PhD is a 3-4 year study you can do after getting a degree at University. This gives you the title “Dr” although it doesn’t mean you are a medical doctor, I still can’t heal sick people.
During a PhD you study a subject in great detail and write a Thesis which is basically a very long report of what you did and what you found out. I studied how whiting (a fish that lives in the North Sea a bit like cod) catch and handle their prey (in this case shrimps). One of the things I did was to use video to record their feeding so I could slow it down and see how they captured different sized shrimps. Basically I could see whether it was better to eat lots of small shrimp that were easy to catch or eating less harder to catch bigger shrimp. I was able to see that as the fish filled their stomachs and became less hungry their feeding choices changed. I built a computer model that would help me predict what different sized fish would choose to eat.
