101 Tips

Welcome to 101 Tips, where we’ll share tips, tricks and historical info related to raising Zebrafish in the lab. Why 101? Seems like a lofty and reasonable goal, we’ll slowly post these and continue to share the most pertinent information available.

Tip 1:

Did you know that rotifers were once considered a pest in traditional Japanese aquaculture do to their rapid generation time in eel rearing ponds? Now these small critters (80–300 microns) are key in zebrafish labs and marine aquaculture hatcheries.

Tip 2:

What are the dissolved oxygen requirements for laboratory zebrafish and why is it important?

Currently the optimal dissolved oxygen level of laboratory zebrafish has not yet been determined. It is recommended that DO2 levels be maintained at or just under saturation (~7.8 mg/L at 28.0°C) based on their high metabolic rates as a small-bodied warm water species.
