The vertical distribution of small o group anguilla larvae in the sargasso sea with reference to other anguilliform leptocephali

Schoth, M.; Tesch F W.

Further evaluations of Mocness-hauls (multiple opening/closing net) in 1979 and of a 1 day haul in 1981 reveal that small 0-group Anguilla larvae, 5.0 mm body length and longer, perform a more distinct diel vertical migration with increasing size. Their preferred depths during darkness and daylight and the vertical distributions of several other anguilliform larvae, which were caught in various quantities (i.e., Serrivomer beani, S. brevidentatus, Derichthys serpentinus, Nemichthys scolopaces, Eurypharynx pelecanoides, Anarchias yoshiae and Arisoma balearicum) are discussed; 5 other anguilliform species [Gnathophis sp., Paraxenomystax sp., Kaupichthys hyoproroides, Chlopsis bicolor, and Chilorhinus seunsoni] caught only sporadically are also reported.
