Fish Playpens: Method for Raising Individual Juvenile Zebrafish on a Recirculating System for Studies Requiring Repeated Measures.

ABSTRACT

Even though many experimental approaches benefit from tracking individual juvenile animals, there is yet to be a commercial zebrafish rack system designed to accomplish this task. Thus, we invented playpens, an acrylic, and screen container, to raise 12 individual zebrafish juveniles per standard 10 L tank on an existing recirculating fish system. During a week-long experiment, fish raised in playpens grow to the same size as conventionally raised juveniles.
