ABSTRACT


To explore whether the endangered White's seahorse Hippocampus whiteiwould
choose to inhabit artificial over natural habitats, ten adult H.
whiteiindividuals were put through a series of binary choice trials in
aquaria, during which they were offered different paired combinations of
natural (different types of macroalga and seagrass) and artificial habitat
(panels of swimming‐net material). It was found that H. whitei displayed a
significant choice for swimming‐net material over all other available
natural habitats and chose habitats according to the following rankings: (1)
Net; (2) Sargassum sp.; (3)Posidonia australis; (4) Zostera muelleri.
Hippocampus whitei's choice of swimming net material over natural habitat
suggests that these artificial structures could be a useful conservation
measure for seahorses in areas where natural habitat is becoming less
favourable due to declines in abundance or quality.
