Burt's Blog

Hi everyone, Pia here! I’m a fry, which is just a fancy name for a baby fish. You might remember that my mom Toni is a mouthbrooder. That means she protects us fry in her mouth while we grow up! Before we get released from her mouth, we have yolk sacs that we use to feed ourselves and we don’t get to see or do too much – we just stay nice and protected inside mom’s mouth until we’re big enough to swim and eat on our own! Once we’re released, there’s SO much to do and see! We have to find our own food, communicate with other fish, and escape from predators back to the safety of mom’s mouth. Plus, there’s lots to see around our tank like our fancy clay pot shelters and the scientists when they come to visit! Because the environment is so different inside and outside our mom’s mouth, the scientists wanted to see which brain regions we use before and after we leave. They looked for a molecule in our brains called pS6 which tells them which neurons were “turned on” or “activated” while we w

Hey guys, Tyrone here! I’m feeling down lately because I’ve been dealing with bullying a lot, especially from Burt. So, I’ve been trying to figure out how I should act when he inevitably decides to be mean to me again. Fortunately, the scientists in the lab care about my behavior and want to figure out what makes a fish susceptible or resilient to bullies like Burt! To cheer myself up, today I want to tell you all about the fun way the scientists study my behavior after repeatedly being bullied in a resident-intruder experiment (if you don’t remember the details check out my previous blog posts about this!). The scientists start with videos of these experiments to quantify our behavior. They specifically want to see how the intruder (like me, Tyrone) reacts to aggression from the resident (like Burt). By using a cool program called BORIS (which stands for B ehavioral O bservation R esearch I nteractive S oftware) they are able to see just how often and for how long we display certa
