Which sex of the Yellow Perch generally grows faster and achieves greater ultimate sizes?
Answer
Females
A pronounced sexual dimorphism exists within the Yellow Perch population concerning growth and longevity. Specifically, females exhibit a biological advantage where they generally grow faster throughout their lifespan and consequently achieve greater ultimate sizes compared to their male counterparts. For example, a female seven years old might surpass a male of the same age by approximately 2.5 centimeters in length. This differential growth rate is a key factor in life history variation observed across different environments.
