Abstract

Herbivorous fish are generally considered to be diurnal feeders, but the disappearance of seaweeds at night has been observed in Japan. We conducted field experiments using an infra-red time-lapse camera to identify fish browsing on seaweed at night at two sites on Fukue Island, western Japan. At both sites, brown chub (Kyphosus bigibbus) were photographed around transplanted seaweed from sunset to sunrise, and the seaweed declined after the appearance of K. bigibbus. This study is the first report of nocturnal browsing in a purely herbivorous fish.

期刊介绍: The Journal of Fish Biology is a leading international journal for scientists engaged in all aspects of fishes and fisheries research, both fresh water and marine. The journal publishes high-quality papers relevant to the central theme of fish biology and aims to bring together under one cover an overall picture of the research in progress and to provide international communication among researchers in many disciplines with a common interest in the biology of fish.
