I found this video to be quite interesting. It's 33 minutes long, showcasing how fish are captured in Indonesia, how they are quarantined, measured, and prepared for travel. One moment that caught my eye was how they added air to the bags initially using a hose from an inflated inner tube. The fisherman are creative, and of course want their efforts to result in success rather than death. Overall, this video gives hobbyists a realistic overview of how fish come from there to our homes. Hopefully you have the time to watch the entire thing.
