What is the required structure where female yellow perch affix their masses of eggs?
Answer
Submerged vegetation, sticks, or debris in shallow, still water
Yellow perch utilize a non-nesting, broadcast method for reproduction, characterized by the females laying their eggs in distinctive long, gelatinous ribbons or strands. These masses are not simply dropped; they must be adhered to firm substrates to ensure proper development. The preferred locations are shallow areas characterized by slow-moving or still water where there is ample presence of submerged aquatic vegetation, sticks, or other debris. These firm surfaces provide the necessary attachment points for the gelatinous ribbons, offering a basic level of protection until the embryos hatch.
