Larval propagation refers to the process by which certain organisms, such as insects and marine animals, reproduce by releasing larvae into the environment. These larvae are immature forms that undergo various developmental stages before maturing into adults. This method allows for a greater dispersal of offspring, increasing the chances of survival in diverse habitats. In many species, larval propagation occurs through external fertilization, where eggs and sperm are released into the water or air. The larvae often have different feeding habits and habitats compared to their adult forms, which helps reduce competition for resources as they grow and develop into their final forms.
