The obtention of floating macroalgae debris in waters of southern Chile, for the first time allowed to explore the presence of fishes swimming together with such kind of ensemble. The presence of the following three species was recorded: the pipefish Leptonotus blainvilleanus (Family Syngnathidae), the chicy ruff Seriolella porosa (Family Centrolophidae); the starry butterfish Stromateus stellatus (Family Stromateidae) and the thornfish Bovichtus sp. (Family Bovichtidae). The last one, a specimen different from Bovichthus chilensis, the only species of the genus known in South America. The finding of representatives of these species allowed the addition of new antecedents, potentially important to explain aspects of their geographical distribution

 

Key words: Ichthyogeography, Bovichtus, Leptonotus, Seriolella, Stromateus
