  • Population dynamics of the jellyfish Pelagia noctiluca (Forsskål, 1775)
    Malej, Alenka, 1948- ; Malej, Matevž
    Recurring massive appearances of different coelenterate species may cause considerable ecological as well as commercial impacts in affected areas, yet our knowledge of the population dynamics of ... these animals is poor. We examined the seasonal occurence, size structure, patterns of growth and mortality of the jellyfish Pelagia noctiluca (Semaeostomeae, Scyphozoa) in the northern Adriatic Sea. The occurrence of mature specimens throughout the year and of ephyrae from April to December indicate a long spawning season, although size-frequency dta suggest a peak spawning period from August to November. The growth curve fitted to a set of bell-diameter-frequency data suggests that P. noctiluca reached the minimal size at which they may spawn inabout 150 days...
