Colony Feeding Method

The colony feeding method is a controlled technique for supplying food to a colony of organisms while monitoring how feeding conditions affect colony maintenance, growth, or behavior. It works by standardizing the food type, quantity, timing, and delivery conditions, while controlling environmental factors such as temperature, humidity, and contamination. Researchers use this approach to compare resource use, evaluate population responses, and maintain laboratory or field colonies under defined conditions. By linking feeding practices with measurable biological outcomes, the method supports studies of colony ecology, environmental adaptation, and the effects of changing resource availability.

Larval zebrafish are adapted to feed on zooplankton. It is possible to capitalize on this natural feature in the laboratory by growing first feeding fish together in the same system with live saltwater rotifers. This "polyculture" strategy promotes high growth and survival with minimal labor and disturbance to the larvae.
