Question:

What is the ontogenetic migration?

Author: Asger LIndberg-Nielsen



Answer:

Ontogenetic migration: Different stages (life cycle) at different depths. Early life stage already have food and don’t need to feed. Don’t need to be at surface Intermediate larval stages – to weak to swim up and down. They don’t search up and down for food. cannot take part in dial-veritical migration They are not as deep as shown in figure.
