Abstract

The mating behaviour, fecundity characteristics and egg production process were investigated in the barbed pipefish Urocampus nanus under aquarium conditions. The mating behaviour consisted of five motor patterns, some of which have been generally reported in other syngnathids. Neither the number nor size of newborns related to the size of parents, although there was a negative correlation between the number and size of newborns. The ovary consisted of two germinal ridges, and mature eggs were produced synchronously with multiple ovulations. This type of egg production has thus far been reported only in a polyandrous and sex-role-reversed pipefish.
