An efficient mass culture method for <i>Beroe cucumis</i>

This study reports an effective and simple method for culturing the comb jellyfish, Beroe cucumis. The breeding another jelly, Bolinopsis mikado, was published by Ikeda et al. (2022), in which mikado bred stably large numbers, then provided as food to developing Fertilized eggs were found a 235-L tank two days after five parental cucumis housed tank, individuals isolated from next day. day found, larvae (0.54 ± 0.04 mm long (n = 9)) observed daily fed mikado. only during early stages of development. They reached total length approximately 10 17 days, 20, when most had grown (approximately 12 over) enough not pass through 3-mm perforated plates, they moved 145-L display tank. Thereafter, reared same manner successfully propagated cumulatively more than generations. greatest advantage this culture is that need be until reach size required display. Therefore, stable can achieved feeding its with reducing labor stress on organisms frequent water changes.
