Abstract

Artificial substrates in coastal areas provide suitable habitats for jellyfish (Cnidaria, Scyphozoa) polyps. Here, we examined the population dynamics of jellyfish polyps as a function of substrate unit variation using delayed differential equations. The time delay in the equations was set to 1 year; that is, the effects of increasing available substrate appeared with a 1-year delay. An increase in the amount of substrate resulted in an exponential increase in the polyp population, although survivorship was reduced by 95% as a result of natural processes. To reduce the jellyfish polyp population, two scenarios and their effects were simulated: a change in polyp survivorship condition on the substrate and the removal of artificial substrate. The delayed effects of different survivorship conditions generated oscillations in polyp populations, with blooms occurring in alternate years, whereas decreasing the amount of artificial substrate available reduced the effective carrying capacity and, consequently, the polyp abundance. Simulation results further indicated that limiting jellyfish blooms in coastal areas is only possible if the amount of artificial substrate is reduced or removed.
