Aspects of the Distribution of Lanternfishes (Pisces: Myctophidae) from the Northern Sargasso Sea
Abstract:Sampling in the northern Sargasso Sea using Isaacs-Kidd midwater trawls, neuston and plankton nets resulted in the capture of 4,180 lantern fishes (Pisces: Myctophidae). Sixteen genera and 45 species were identified. Relative abundances, shallowest depths of capture and zoogeographic affinities were determined for the 14 most common species. Sixteen species are recorded for the first time in surface waters at night. Size frequency distribution suggests that species generally associated with tropical waters were advected into the study area via Gulf Stream transport as juveniles. The species list and faunal affiliations are in agreement with earlier zoogeographic accounts. The present study fills an important sampling void in the Northern Sargasso Sea zoogeographic province.
