A contribution to the biology of the halfbeak, Hyporhamphus georgii (Cuv. & Val.) (Hemirhamphidae)

Abstract

The hemirhamphids constitute an important group of the neretic-pelagic fisheries of the Gulf of Mannar and Palk Bay. Although there are eight species of halfbeaks distributed in these waters, Hyporhamphus georgii (C.V.) and Hemirhamphus marginatus (Forsk.) are the only species which may be considered of sufficient importance to constitute a distinct ' fishery'. With a view to obtaining accurate information on the fishery biology of these common species, a detailed investigation was taken up during 1957-59.
