| Abstract |
Twenty-four pleurotremate elasmobranch species are recorded from the Languedoc coast. Biological and demographic observations on 15 species are presented in this paper. The biological observations essentially concern size at birth, size at sexual maturity, maximal size and, wherever possible, reproductive cycle and fecundity. A single species is regularly and abundantly captured: the smallspotted catshark, Scyliorhinus canicula. Two other species arc relatively common, namely the blackmouth catshark, Galeus melastomus, and the velvet belly, Etmopterus spinax. A constant decrease of species having a commercial value is observed, particularly Mustelus spp. and Squalus spp. The other species are occasionally captured, e.g. the great migratory sharks and the deep-sea squalids. |
