Carbon content of Mnemiopsis leidyi eggs and specific egg production rates in northern Europe Academic Article uri icon

abstract

  • The comb jelly Mnemiopsis leidyi is considered to be a successful invasive species, partly due to its high reproduction potential. However, due to the absence of direct carbon measurements of eggs, specific reproduction rates remain uncertain. We show that egg carbon is 0.22 ± 0.02 µg C and up to 21 times higher than previously extrapolated. With maximum rates of 11 232 eggs ind?1 day?1, largest animals in northern Europe invest ?10% day?1 of their body carbon into reproduction.
