…like I do, here’s a useful resource: Regular Care and Maintenance of a Zebrafish (Danio rerio) Laboratory: An Introduction. It’s text and a video guide to familiar procedures.
Unfortunately, it also assumes you have a commercial zebrafish rack, which if you buy the smallest size available, will set you back about $10,000. I’ve just been using an array of 5 gallon tanks, each with its own filter system, which is cheap to set up, but a pain to maintain. I’m going to bite the bullet and build my own DIY flow-through system this summer, though, which I expect will cost a few hundred dollars…which is more in my budget. If you want to follow along, here’s a paper on a Modular, Easy-to-Assemble, Low-Cost Zebrafish Facility — it’ll be something like that. It’s not exactly the kind of show aquarium you’d have in your home, but if all you care about is embryo throughput, it’s loads of fun and lower maintenance than what I’ve been doing so far.
