Fiordos de Chile: Potencial zona de crianza de Bathylagichthys parini (Pisces: Osmeriformes: Bathylagidae)

Eighteen juveniles of Bathylagichthys parini (Osmeriformes: Bathylagidae) were collected in fjords of southern Chile (ca. 48°S-74°W) in November 2008. Standard length and wet weight ranged from 22.6 to 37.7 mm, and between 0.049 and 0.243 g, respectively; density ranged between 3.56 and 41.77 juveni...

Description
Résumé:Eighteen juveniles of Bathylagichthys parini (Osmeriformes: Bathylagidae) were collected in fjords of southern Chile (ca. 48°S-74°W) in November 2008. Standard length and wet weight ranged from 22.6 to 37.7 mm, and between 0.049 and 0.243 g, respectively; density ranged between 3.56 and 41.77 juveniles x 10 m². Stomach contents included calanoid copepods (mainly Acartia tonsa and Paracalanus parvus adults and copepodids), ostracods and mussel larvae. This finding suggests that juveniles feed near surface waters and aids evidence to the hypothesis the fjords are utilized as nursery zone for this rare oceanic species from South Pacific.
