What dominates the diet of newly hatched yellow perch fry, often measuring less than half an inch long?
Answer
Zooplankton
When yellow perch first hatch, they are very small, typically under half an inch in length. Their initial survival is entirely dependent on consuming microscopic organisms suspended in the water column. This foundational food source that supports their rapid initial growth consists overwhelmingly of zooplankton. A weak or insufficient bloom of these organisms directly leads to a rapid decline in survival rates for the young perch, highlighting its critical role in their earliest life stage.
