tonsa under high density conditions may be a reproductive strategy used in localized patches of superabundant food and few predators to compensate for future predation pressure and food shortages, and may also be a means to stockpile current food surplus with reproduction and subsequent cannibalism on the naupliar stages when the food source diminishes.

However, naupliar and copepodite growth and development are severely limited when individuals are raised on monospecific cyanobacterial diets (Xu and Burns 1991), and the demographic consequences for Boeckella of cyanobacteria remain uncertain, particularly when this "poor quality" food is ingested together with other algal species.

Abstract.--In symbiotic copepods, most naupliar stages are typically planktonic, playing a primary role in dispersal, while the first copepodid usually represents the infective stage.
