Reproductive behaviour of the long-snouted seahorse Hippocampus guttulatus under culture conditions

2 pages, 1 figure.-- Contributed to the International Conference AQUACULTURE EUROPE 2008 (Krakow, Poland, Sep 15-18, 2008).Seahorses have been considered monogamous but only a few seahorse species have been investigated. The European long-snouted seahorse Hippocampus guttulatus is a data deficient species (IUCN, 2006). One of the unknown aspects of its biology concerns its reproductive behaviour. The present study shows the results achieved on courtship and mating behaviour in long-snouted seahorses maintained under captive conditions during two successive breeding seasons.Financed by the Spanish Ministry of Science and Technology (CGL2005-05927-C03-01) and Xunta de Galicia (PGIDIT06PXIC402106PN, PGIDIT06PXIA402066IF).Peer reviewe
