Goldspotted spinefoot Siganus punctatus (Siganidae) age-based reproductive life history and fisheries vulnerability.

Between February 2015 and 2016, samples of the Indo-Pacific goldspotted spinefoot Siganus punctatus were taken from local fish markets, feeding sites and nursery grounds on the main island of Pohnpei, Micronesia, to ascertain sexual pattern, reproductive seasonality, age, growth and mortality. Microscopic examinations of gonads identified two seasonal peaks in reproduction: February to May and September to December, with evidence of some spawning activity in most months. Ripe females were observed 4 days on either side of the new moon.
