Abstract

This study investigated ovarian structure and mode of egg production in the seaweed pipefish, Syngnathus schlegeli. The ovary had a rolled sheet-like structure where developing follicles were arranged serially in sequence according to their development, with a single germinal ridge running along the edge of the sheet. Oocytes of various developmental stages were concomitantly present in the ovary, and the number of mature eggs increased continuously over time, indicating that egg production is asynchronous. This would be a physiological basis for multiple spawning within a short time span associated with polygamy in this fish.
