What is the term for all individuals that hatch at one time from eggs laid by the same parents?

The term "brood" is used to refer to all individuals that hatch at one time from eggs laid by the same parents. This term is commonly applied in the context of various species, particularly in ecology and animal husbandry, to describe a group of offspring produced during a specific reproductive event.

Broods often have similar traits and are exposed to the same environmental conditions during their early development, influencing their survival and growth. Understanding the concept of a brood is essential in aquatic pest control, as it helps professionals to identify and manage population dynamics effectively, particularly in assessing the potential impact of a pest species on ecosystems.

In contrast, the other terms listed, such as "batch," "litter," and "cluster," are generally associated with different contexts of reproduction or collection. A "batch" typically refers to a quantity produced at one time, often used in manufacturing rather than biology. "Litter" refers to a group of young animals born to the same mother at one time, commonly used in mammals, but does not apply as directly to hatching from eggs. "Cluster" usually describes a collection of similar items grouped together, not specifically in the context of offspring or reproductive output.
