An Optimized Zebrafish Nursery Feeding Regimen Improves Growth Rates and Labor Costs.

Setting nutritional standards for larval zebrafish () that maximize growth, survival, and reproductive success is challenging. We evaluated the effects of different feeding regimens on larval zebrafish by comparing Gemma Micro 75 pelleted diet and live-type L rotifers () in 3 feeding regimens starting at 9 days postfertilization (dpf): bolus feeding of live diet (BL), continuous feeding of live diet (CL), and pelleted diet (PD). Animals in the PD and CL groups were longer than the BL group at 4-5 weeks postfertilization.
